Molecular Structures

Antifreeze proteins are found in a wide range of overwintering
plants where they inhibit the growth and
recrystallization of ice that forms in intercellular spaces.
Unlike antifreeze proteins found in fish and insects,
plant antifreeze proteins have multiple, hydrophilic icebinding
domains. Surprisingly, antifreeze proteins from
plants are homologous to pathogenesis-related proteins
and also provide protection against psychrophilic
pathogens. In winter rye (Secale cereale), antifreeze
proteins accumulate in response to cold, short daylength,
dehydration and ethylene, but not pathogens.
Transferring single genes encoding antifreeze proteins
to freezing-sensitive plants lowered their freezing
temperatures by w18C. Genes encoding dual-function
plant antifreeze proteins are excellent models for use in
evolutionary studies to determine how genes acquire
new expression patterns and how proteins acquire new
activities.

Within a liquid drop model the energy of the 12 C, 16 O, 20 Ne, 24 Mg and 32 S 4nnuclei has been calculated within different configurations of α-molecules : linear chain, triangle, square, tetrahedron, pentagon, trigonal bipyramid, square pyramid, hexagon, octahedron, octagon and cube. The potential barriers governing the decay and entrance channels via α emission or absorption as well as the potential barriers of other possible binary and ternary reactions have been compared. The rms radii of the linear chains do not correspond to the experimental rms radii of the ground states. The binding energies of the three-dimensional molecules at the nascent point of the fragments are higher than the ones of the planar configurations. The A-4 daughter plus α particle configurations have always the lowest potential energy.

We report the synthesis of peripherally alkylated dithienosilole (DTS) and dithienogermole (DTG) monomers that possess side chains of different lengths (methyl vs. butyl) attached to a bridging heavy atom (Si or Ge) and the resulting copolymers with benzothiadiazole (BT) units. We study the optoelectronic and charge transport properties of these copolymers, with a particular focus on their use for bulk heterojunction photovoltaic devices in blends with phenyl-C70-butyric acid methyl ester (PC70BM). Enhanced charge carrier mobility is observed by substituting Si atom with Ge atom and better mixing of copolymers with PC70BM desirable for better charge generation is obtained by shortening the side chain length of copolymers from butyl to methyl groups. We observe a very high open circuit voltage (Voc = [similar]0.94 V) in single layer blend devices (polymer:PC70BM = 1 : 4 by weight in DCB) with good device performance (PCE = 2.66%, Jsc = 6.11 mA cm−2, FF = 0.46) using Ge substituted copolymers with methyl side groups. Neither additional pre- or post-thermal annealing steps nor additives to the photoactive blend layer are needed to achieve such device performance. Based on detailed investigation including absorption, emission, charge carrier mobility and quantum chemical calculations for molecular geometry and electronic energy levels, we clarify the role of the heavy atom substitution in the donor–acceptor bridged copolymers and discuss their effects on device performance in bulk heterojunction photovoltaic cells.

In the present work, an effort has been made to develop suitable process conditions for synthesis of carbon molecular sieve (CMS) from a locally available palm shell of Tenera type. The process involves three stages; carbonization, physical activation with steam, and carbon deposition by using benzene cracking technique. The highest micropore volume of activated carbon was obtained at 53.2% burn-off,

Electron beam lithography (EBL) patterning of poly(methylmethacrylate) (PMMA) is a versatile tool for defining molecular structures on the sub-10-nm scale. We demonstrate lithographic resolution to about 5 nm using a cold-development technique. Liftoff of sub-10-nm Au nanoparticles and metal lines proves that cold development completely clears the PMMA residue on the exposed areas. Molecular liftoff is performed to pattern DNA rafts with high fidelity at linewidths of about 100 nm. High-resolution EBL and molecular liftoff can be applied to pattern Creutz-Taube molecules on the scale of a few nanometers for quantum-dot cellular automata.

Lubrication is an art that has been practiced for thousands of years from the early days of our human civilization. The study of lubrication as a science began in the 17th century with the development of bearings and axles. In the early 21st century, the advent of automobiles and steam engines spurred the development of modern complex lubricants consisting of base oils and chemical additives. The development, however, has been mostly empirical in nature. The detailed mechanisms of the chemistry and why they worked were not understood. Rapid advancements in analytical instrumentations and techniques in the last several decades offer an unprecedented opportunity to analyze the complex chemistry and probe the surfaces for chemical evidence. Recent developments in nanotechnology provide further ability to examine phenomena and mechanisms at the nanometer level. As a result of these advances, our understanding of the complex lubrication system has improved significantly. This paper will attempt to provide a molecular basis of how lubricant and additives function in lubrication. Monomolecular thin films have been developed to investigate the fundamental mechanism of boundary lubricating films. Results provide additional insights of how antiwear films work in the lubrication system. Prospect for applying this know-how may result in a revolutionary change in our current lubricating technology.

In the present work, rarefied gas flow between two parallel moving plates maintained at the same uniform temperature is simulated using the direct simulation Monte Carlo (DSMC) method. Heat transfer and shear stress behavior in the micro/nano-Couette flow is studied and the effects of the important molecular structural parameters such as molecular diameter, mass, degrees of freedom and viscosity-temperature index on the macroscopic behavior of gases are investigated. Velocity, temperature, heat flux and shear stress in the domain are studied in details. Finally, a discussion on the role of the molecular structural parameters in the decrease or increase of amounts of hydrodynamics and thermal properties of the gas is presented.

BaH (and its isotopomers) is an attractive molecular candidate for laser cooling to ultracold temperatures and a potential precursor for the production of ultracold gases of hydrogen and deuterium. The theoretical challenge is to simulate the laser cooling cycle as reliably as possible and this paper addresses the generation of a highly accurate ab initio 2 ⌃ + potential for such studies. The performance of various basis sets within the multi-reference configuration-interaction (MRCI) approximation with the Davidson correction is tested and taken to the Complete Basis Set (CBS) limit. It is shown that the calculated molecular constants using a 46 electron e↵ective core-potential and even-tempered augmented polarized core-valence basis sets (aug-pCVnZ-PP, n = 4 and 5) but only including three active electrons in the MRCI calculation are in excellent agreement with the available experimental values. The predicted dissociation energy D e for the X 2 ⌃ + state (extrapolated to the CBS limit) is 16 895.12 cm 1 (2.094 eV), which agrees within 0.1% of a revised experimental value of <16 910.6 cm 1 , while the calculated r e is within 0.03 pm of the experimental result.

Fluorescence emission spectra are reported for naphth[2',l',8',7': 4,10,51anthra [1,9,8cdeflcinnoline, benzo[lmnl[3,81phenanthroline (also called 2,7-diazapyrene), benz[4,10]anthrall,9,8cdeflcinnoline, naphtho[8,1,2hijlpyreno[9,10,1deflphthalazine, acenaphtho[1,2b]pyridine, benzo[alphenazine, indeno[1,2,3ijl[2,71naphthyridine, and indeno-[1,2,3ijlisoquinoline dissolved in organic nonelectrolyte solvents of varying polarity and acidity. Results of these measurements indicate that naphth[2',l',8',7':4,10,51anthra[1,9,8cdeflcinnoline exhibits some signs of probe character as evidenced by changing emission intensity ratios; however, numerical values did not vary systematically with solvent polarity. The effect of nitromethane and 1,2,4-trimethoxybenzene as selective quenching agents on both the unprotonated and protonated PANHs was also examined. Nitromethane was found to quench fluorescence emission of roughly two-thirds of the alternant unprotonated PANHs studied to date. Emission intensities of the protonated PANHs remained essentially constant and were not affected by nitromethane. 1,2,4-Trimethoxybenzene, on the other hand, quenched the fluorescence emission of several unprotonated and all protonated PANHs examined.

The influence of anellation on the properties and structures of heterocyclic diaminogermylenes was studied. Benzo-and pyrido-anellated cyclic germylenes 1,2-C 6 H 4 [N(CH 2 t Bu)] 2 Ge (1) and 2,3-C 5 H 3 N[N(CH 2 t Bu)] 2 Ge (2) were synthesised by dilithiation of aromatic ortho-diamino compounds C 5 H 3 X[N(CH 2 t Bu)] 2 (X =CH, N) with BuLi and subsequent reaction with GeCl 2 (dioxane), the non-anellated but analogously N, was obtained by reductive metalation of N,N%dineopentyl-glyoxal diimine with lithium and cyclisation with GeCl 2 (dioxane). Crystal structure determinations on 1 -3 give evidence on their monomer nature and lack of interactions between Ge(II) and the basic pyridine N-atom in 2. Spectroscopic data and structures of anellated and non-anellated compounds were compared. The sensitivity to distortions of bond lengths in the germylene 3 as compared to 1 and 2 may hint to a lower stability of the non-anellated diazagermoline-2-ylidene p-system as compared with the 10p-system in the anellated compounds 1 and 2, which are favoured by the intrinsic stability of the o-arenediimine fragment.

Crystalline N,N-cyclo-pentamethylenedithiocarbamate (PmDtc) cadmium(II) complex was prepared and studied by means of 15 N, 113 Cd CP/MAS NMR spectroscopy and single-crystal X-ray diffraction. The unit cell of the cadmium(II) compound comprises two centrosymmetric isomeric binuclear molecules [Cd 2 {S 2 CN(CH 2) 5 } 4 ], which display structural inequivalence in both 15 N and 113 Cd NMR and XRD data. There are pairs of the dithiocarbamate ligands exhibiting different structural functions in both isomeric molecules. Each of the terminal ligands is bidentately coordinated to the cadmium atom and forms a planar four-membered chelate ring [CdS 2 C]; whereas pairs of the tridentate bridging ligands combine two neighbouring cadmium atoms forming an extended eight-membered tricyclic moieties [Cd 2 S 4 C 2 ], whose geometry can be approximated by a 'chair' conformation. The structural states of cadmium atoms were characterised by almost axially symmetric 113 Cd chemical shift tensors. All experimental 15 N resonance lines were assigned to the nitrogen structural sites in both isomeric binuclear molecules.

Reaction of the cyclic triphosphenium ion derived from dppe and PCl 3 with SbCl 5 did not cause chlorination at the middle phosphorus atom, but has led to isolation of the ionic title compound [Ph 2 P(Cl)CH 2 CH 2 P(Cl)Ph 2 ] 2' [SbCl 5 ] 2(, the structure of which has been ascertained by X-ray crystallography. The cation has been structurally characterised for the first time; the geometry about each phosphorus atom is approximately tetrahedral, with a slightly larger angle between the bulky phenyl groups than between the other ligands. The pentachloroantimonate(III) anion exists as an isolated species, with a stereochemically active lone pair. This gives an approximately square pyramidal structure, with the shortest SbÃ/Cl bond trans to the lone pair position.

The hydrogen-bonded molecular complexes formed between methanol and dimethylamine, as proton donors, and the series of proton acceptors trimethylamine, dimethyl ether, methyl fluoride, trimethyl phosphine, dimethyl sulphide and methyl chloride, have been studied by means of ab initio molecular orbital theory, at the second order level of Møller-Plesset perturbation theory, and using the 6-311++G(d,p) basis set. The properties determined were the molecular structures, the interaction energies and the vibrational spectra. The results show that, based on the trends in the values of these properties, the order of strength of interaction per proton donor is methanol > dimethylamine and the order per proton acceptor is trimethylamine > dimethyl ether > methyl fluoride for the first row bases and trimethyl phosphine > dimethyl sulphide > methyl chloride for the second row. The first row proton acceptors consistently form stronger hydrogen-bonded complexes than their counterparts from the second row.

The structures, interaction energies and vibrational spectra of the electron donor-acceptor complexes formed between silicon tetrafluoride and the common Lewis bases ammonia, water, phosphine and hydrogen sulphide have been determined by means of a series of ab initio molecular orbital calculations. The results confirm the trends observed in our previous studies of the complexes formed between the same four bases and the Lewis acids boron trifluoride and sulphur dioxide. The analogous complexes of silicon tetrafluoride with hydrogen fluoride and hydrogen chloride were also examined and, consistent with our earlier findings concerning the adducts of boron trifluoride and sulphur dioxide with these two diatomic species, were found to be very weakly-bound, if at all.

Chemistry students experience a number of problems during the learning process in subjects like molecular biology, biochemistry and others, particularly when they study molecular structure, since it is generally complex and abstract. This paper describes a proposal of learning object development to support understanding of molecular structures, using multimodal virtual reality technology. This paper also comments the development of a test bed for analyzing the possible applications and limitations of the technology and pedagogical contents of learning objects in virtual reality.

Imino-quinolyl ligands L1-L5 were synthesized by condensation reactions and obtained in good yields. Reactions of the ligands with either PdCl2 (cod) or K2 [PtCl4 ] gave the corresponding palladium(II) and platinum(II) complexes 1-10 also in good yields. All the compounds were characterized by elemental analysis, IR, 1 H and 13 C NMR spectroscopy. X-ray crystallography was used to confirm the structures of these compounds. Molecular structures of 3 and 5 showed that the ligands coordinate to the metal centre through the two nitrogen atoms, generating a distorted square planar geometry around the palladium atom. The new complexes exhibited remarkable cytotoxic activities against MCF-7 and HT-29 cancer cell lines.

In this chapter,  the diamondoid molecules which are cage-like organic (saturated hydrocarbons) with unique structures and properties are presented. These molecules are ringed compounds, which have a diamond-like structure consisting of a number of six-member carbon rings fused together. More explicitly, they consist of repeating units of ten carbon atoms forming a tetra-cyclic cage system. They are called “diamondoid” because their carbon–carbon framework constitutes the fundamental repeating unit in the diamond lattice structure.
Also, the general aspects of how to define and classify diamondoids is discussed. Difference between diamondoids and NDs are pointed out. The Lewis acid-catalyzed rearrangement of hydrocarbons to synthesize lower diamondoids is presented and its limitations for the synthesis of higher diamondoids are discussed. Classical methods of diamondoid cage chemical syntheses and functionalization, along with recent methods
for higher diamondoid chemical modification set the tone for organic chemistry of diamondoids.

In the present work, an effort has been made to develop suitable process conditions for synthesis of carbon molecular sieve (CMS) from a locally available palm shell of Tenera type. The process involves three stages; carbonization, physical activation with steam, and carbon deposition by using benzene cracking technique. The highest micropore volume of activated carbon was obtained at 53.2% burn-off, which is then used as a precursor for CMS production. In order to narrow down the pore mouth size to a required size, benzene was cracked at 800 °C for 15-60 min. The characterization of the samples was assessed by physical adsorption of N2 at 77 K. The adsorption kinetic of CO2, CH4, O2 and N2 were measured at room temperature in order to determine the sample behavior as CMS. © 2007 Elsevier B.V. All rights reserved.

The reaction of [Sm(Tp Me2 ) 2 ] with Mn 2 CO 10 results in the reductive cleavage of the Mn Á/Mn bond and the formation of the salt [Sm(Tp Me2 ) 2 ]Mn(CO) 5 which has been characterized by X-ray diffraction (Tp Me2 0/HB(3,5-dimethylpyrazolyl) 3 ). In addition a second product, [(Tp Me2 ) 2 Sm(m-O 2 CH)Sm(Tp Me2 ) 2 ]Mn(CO) 5 , was isolated and characterized crystallographically. Two mechanisms for the formation of this complex are proposed. #

Carbon molecular sieves (CMS) have been prepared from locally available palm shell of Tenera type by a thermal treatment technique involving carbonization followed by steam activation and benzene deposition technique. Carbonization of the dried palm shells was done at 900 °C for duration of 1 h followed by steam activation at 830 °C for 30–420 min to achieve activated carbons with different degree of burn-offs. The highest micropore volume of activated carbon obtained at 53.2% burn-off was found suitable to be used as a precursor for CMS production. Subsequent benzene deposition onto activated samples at temperature range from 600 to 900 °C for various benzene concentrations have resulted in a series of CMS with different kinetic selectivities. The molecular sieving behaviour of the CMS products was assessed by kinetic adsorption isotherms of O2, N2, CO2 and CH4 at room temperature.

Making further advances in such diverse problems as building more powerful computers, measuring material properties of biological samples or exploring fundamental physical laws on the atomic level requires gaining access the to the nanoworld. The nanoManipulator system adds a virtualreality interface to an atomic-force microscope (AFM), thus providing a tool that can be used by scientists to image and manipulate nanometer-sized molecular structures in a controlled manner. As the AFM tip scans the sample, the tipsample interaction forces are monitored which, in turn, can yield information about the frictional, mechanical, material and topological properties of the sample. Computer graphics are used to reconstruct the surface for the user, with color or contours overlaid to indicate additional data sets. Moreover, a force feed-back stylus, which is connected to the tip via software, allows the user to directly interact with the macromolecules. This system is being used to investigate carbon nanotubes, DNA, fibrin, adeno-and tobacco-mosaic virus. Nanotubes have been bent, translated and rotated to understand their mechanical properties and to investigate friction on the molecular level. Using AFM lithography in combination with the nanoManipulator, the electromechanical properties of carbon nanotubes are being investigated. The rupture forces of DNA and fibrin fibers have been measured and the elastic moduli of viruses are being studied. It is now also possible to insert this system into a Scanning Electron Microscope (SEM) which provides the user with continuous images of the sample, even while the AFM tip is being used for manipulations. Investigators are invited to apply to use the system as described on the web at http://www.cs.unc.edu/Research/nano/doc/biovisit.html.

stability of fluorosulfonyl arenes dramatically differing from other haloanhydrides; i.e. a typical purification procedure for aryl sulfonyl fluorides is steam distillation (!). Thus, it should be admitted that, in our opinion, aromatic sulfonyl fluorides may compete with expensive or rare aryl trifluoromethyl sulfones as key compounds for various practical applications.

The molecular structures, electron affinities, and dissociation energies of the As n /As n Ϫ (n ϭ 1-5) species have been examined using six density functional theory (DFT) methods. The basis set used in this work is of doubleplus polarization quality with additional diffuse s-and p-type functions, denoted DZPϩϩ. These methods have been carefully calibrated (Chem Rev 2002, 102, 231) for the prediction of electron affinities. The geometries are fully optimized with each DFT method independently. Three different types of the neutral-anion energy separations reported in this work are the adiabatic electron affinity (EA ad ), the vertical electron affinity (EA vert ), and the vertical detachment energy (VDE). The first dissociation energies D e (As nϪ1 -As) for the neutral As n species, as well as those D e (As nϪ1

For the purpose of investigating alternative adsorbents, new metal-organic compounds were synthesized,
characterized and examined for their hydrogen storage capabilities. First, the compounds were synthesized
and then the molecular structures of the compounds were determined experimentally by using thermal, FT-IR,
solid-UV and powder-XRD analysis. Then, the crystal structures were solved using theoretical calculations. At
last, the simulated maximum hydrogen storage capacities of the compounds were 3.62 and 0.64 wt. % at 77 K
and 100 bars, while the numbers less than 0.1 wt. % for 1 bar and same temperature. In brief, crystal structures
of inorganic compounds are determined with combined experimental and computational techniques, then,
hydrogen storage abilities are investigated
