In menB mutant photosystem 1 particles from the same species, plastoquinone-9 occupies the A1 binding site. By incubation of menB mutant photosystem 1 particles in the presence of phylloquinone, it was shown in another study that phylloquinone will displace plastoquinone-9 in the A1 binding site.

In particular, we derive a circuit model based on ANA measurements. We also demonstrate the first terahertz detection (up to 2.54 THz) in bundles of CNTs that were deposited through dielectrophoresis across the smallest gap in log-periodic antennas. Data are given that support the hypothesis that the detection process is bolometric at THz frequencies.

We describe new techniques for fabrication of log periodic antennas, as well as for better control of the placement and selection of the CNTs.

Unlike charge-based electronics which are prone to leakage at nanoscale dimensions, memory devices based on phase change materials (PCMs) are more scalable, storing digital information as the crystalline or amorphous state of a material. Here, we describe a novel approach to self-align PCM nanowires with individual carbon nanotube (CNT) electrodes for the first time.

bundles of single wall carbon nanotubes (SWCNTs) at the
ISSTT2008, we have fabricated a large number of additional
antenna-coupled SWCNT devices that all show terahertz
detection. The maximum voltage responsivity (SV) is about 25
V/W (intrinsic value 50 V/W) at 4.2 K, and SV decreases slowly
with temperature up to about 100 K. In this paper we further
explore different fabrication procedures and the bolometric
detection process. We also demonstrate diode type detection at
terahertz frequencies in SWCNTs for the first time. We present
results of circuit simulations and ab initio simulations of the
electronic properties of SWCNTs.
