Heavy metals in a polluted environment are toxic to life. However, some microorganisms can remove or immobilize heavy metals through biomineralization. These bacteria also form minerals with compositions similar to those of semiconductors. Here, this bioprocess was used to fabricate semiconductors with low energy consumption and cost. Bacteria that form lead sulfide (PbS) nanoparticles were screened, and the crystallinity and semiconductor properties of the resulting nanoparticles were characterized. Bacterial consortia that formed PbS nanoparticles were obtained. Extracellular particle size ranged from 3.9 to 5.5 nm, and lattice fringes were observed. The lattice fringes and electron diffraction spectra corresponded to crystalline PbS. The X-ray diffraction (XRD) patterns of bacterial PbS exhibited clear diffraction peaks. The experimental and theoretical data of the diffraction angles on each crystal plane of polycrystalline PbS were in good agreement. Synchrotron XRD measurements showed no crystalline impurity-derived peaks. Thus, bacterial biomineralization can form ultrafine crystalline PbS nanoparticles. Optical absorption and current–voltage measurements of PbS were obtained to characterize the semiconductor properties; the results showed semiconductor quantum dot behavior. Moreover, the current increased under light irradiation when PbS nanoparticles were used. These results suggest that biogenic PbS has band gaps and exhibits the general fundamental characteristics of a semiconductor.

Structural studies using multiple powder profiles were described with two examples. An algorithm for determining the element-selective charge density is developed using multi-wavelength anomalous synchrotron X-ray powder diffraction data. The method is employed in order to resolve the disordered structure of Yttrium in Y@C₈₂(C₆H₅CH₃). Systematic structural studies of 24 different kinds of endohedral metallofullerenes, M_xC_2n(M = La, Y, Sc, Lu, Ti, Eu, Er, Hf, Sc₃N ; 34 ≤ n ≤ 43), as 1 : 1 cocrystals with solvent toluene molecules have been carried out. It is found that the volume for one fullerene and one toluene molecule depends linearly on the number of carbon atoms in the fullerene cage. The linear dependence found in the present study provides a metallofullerene diagnostics diagram that may have universal importance for structural characterization of the so-called cluster endohedral fullerenes.

<p>Mechanochemical reaction between SiO₂ and MoO₃ has provided amorphous mixed metal oxide involving Si–O–Mo linkages. This is a good precursor for the subsequent hydrothermal synthesis to prepare Mo-substituted MFI-type zeolite ([Mo]-MFI), where Mo atoms have tetrahedral coordination geometry. Thus prepared [Mo]-MFI has exhibited unique catalytic activity for oxidative coupling of methane and has produced C₂ compounds with suppression of over-oxidation to CO and CO₂, in contrast to the MoO_x/ZSM-5 catalyst, which has mainly yielded CO and CO₂.</p>

<p>Shale gas revolution motivated researchers to develop heterogeneous catalysts enabling efficient methane transformation. We previously developed a novel preparation method of heteroatom-incorporated MFI-type zeolites via mechanochemical treatment and subsequent hydrothermal synthesis. In this work, SiO₂ and Ga₂O₃ were initially ball-milled together, to form amorphous material. UV-vis and SEM-EDS measurements revealed that Ga atoms had tetrahedral coordination and were highly dispersed in thus prepared material. The hydrothermal treatment using this amorphous material as a precursor successfully generated Ga-incorporated MFI zeolite. In methane conversion over [Ga]-MFI in the presence of oxygen, CO was obtained as a major product.</p>
