The first magnetic circular dichroism (MCD) spectra are reported at room temperature for well-defined thiolate-protected Au 25 clusters (Au 25(SG) 18 and Au 25(PET) 18, where SG and PET denote glutathione and 2-phenylethanethiolate, respectively). MCD essentially corresponds to electronic transitions in the absorption spectrum, so the electronic structures of the Au 25 clusters are explored based on a simultaneous deconvolution analysis of both the electronic absorption and MCD spectra, giving enhanced spectral resolution. We then find that the observed MCD responses are entirely interpreted in terms of the Faraday B terms, representing strict nondegeneracies of the excited and ground states of the Au 25 clusters that correspond to so-called superatom D and P orbitals, respectively. © 2012 American Chemical Society.

Chemically modified fullerenes and chlorinated solvents have been predominantly chosen in the recent studies of the photovoltaic devices based on polymer bulk heterojunction composites. However, these items seem to be undesirable because of their potential impacts on the environment as well as the consumption of resources. In this context, a systematic study on the annealing effect and film composition dependence of bulk heterojunction photovoltaic devices based on composites consisting of poly(3-hexylthiophene) (P3HT) and neat C70 prepared with a chlorine-free solvent 1,2,4-trimethylbenzene has been carried out. For the device using P3HT:C70 composite (2:1 by weight) film as an active layer, power conversion efficiency of 1.47%, with open-circuit voltage of 0.52 V, short-circuit current density of 6.2 mA/cm 2 and fill-factor of 45%, has been obtained after post-production annealing at 160°C. The combination of neat fullerenes with naturally obtained solvents will open up a new way to produce cost-effective and environmentally-friendly photovoltaic devices based on polymer:fullerene bulk heterojunction composites. © 2012 Elsevier B.V.

The enzyme hydrogenase reversibly converts dihydrogen to protons and electrons at a metal catalyst. The location of the abundant hydrogens is of key importance for understanding structure and function of the protein. However, in protein X-ray crystallography the detection of hydrogen atoms is one of the major problems, since they display only weak contributions to diffraction and the quality of the single crystals is often insufficient to obtain sub-ångström resolution. Here we report the crystal structure of a standard [NiFe] hydrogenase (∼91.3 kDa molecular mass) at 0.89 Å resolution. The strictly anoxically isolated hydrogenase has been obtained in a specific spectroscopic state, the active reduced Ni-R (subform Ni-R1) state. The high resolution, proper refinement strategy and careful modelling allow the positioning of a large part of the hydrogen atoms in the structure. This has led to the direct detection of the products of the heterolytic splitting of dihydrogen into a hydride (H-) bridging the Ni and Fe and a proton (H+) attached to the sulphur of a cysteine ligand. The Ni-H- and Fe-H- bond lengths are 1.58 Å and 1.78Å, respectively. Furthermore, we can assign the Fe-CO and Fe-CN- ligands at the active site, and can obtain the hydrogen-bond networks and the preferred proton transfer pathway in the hydrogenase. Our results demonstrate the precise comprehensive information available from ultra-high-resolution structures of proteins as an alternative to neutron diffraction and other methods such as NMR structural analysis. ©2015 Macmillan Publishers Limited.

It is an object of the present invention to provide a conveyor which estimates weight of a transport object while it is carried without using devices such as a load cell which directly measures weight. The conveyor has a plurality of zones forming a series of carriage ways. An approach-run zone and a weight-measurement zone are arranged adjacently in the conveying direction and are provided with different drive motors. The drive motor of the approach-run zone and the drive motor of the weight-measurement zone are controlled with respectively different predetermined rotation speeds as their target rotation speeds. A rotation speed sensing means obtains the change of rotation speed of the drive motor in the weight-measurement zone when a transport object is conveyed into the weight-measurement zone from the approach-run zone, and a weight sensing means then calculates the weight of the transport object based on the change of the rotation speed.
