Abstract The crystallinity of hydroxyalkylformamides‐platicized thermoplastic starch (HAFTPS) was characterized by X‐ray diffraction (XRD). The HAFTPS crystallinity related to the structure of plasticizer hydroxyalkylformamides (HAF). If there was one H atom attaching to N atom of HAF, the corresponding HAFTPS only ha…

Abstract CdSe films have been deposited on glass substrates at different substrate temperatures between room temperature and 300 °C. The films exhibited hexagonal structure with preferential orientation in the (002) direction. The crystallinity improved and the grain size increased with temperature. Band gap values ar…

Independent cryo electron microscopy (cryo-EM) studies of the closely related protein disaggregases ClpB and Hsp104 have resulted in two different models of subunit arrangement in the active hexamer. We compare the EM maps and resulting atomic structure fits, discuss their differences, and relate them to published exp…

Nanostructured NiS was prepared by inclusion into anodic alumina templates. The resultant particles were found to be stoichiometric and highly crystalline. The particles displayed small particle superparamagnetism, and a low temperature (at 48 K (T(sg))) spin-freezing phenomenon (a spin-glass) and higher temperature (…

Complete spectroscopic, structural, and anion-binding properties are reported for a special class of calixphyrins, namely, 5,10-disubstituted porphodimethenes (PDMs). The crystal structure clearly shows that PDMs exhibit nonplanar (distorted) structures with both sp(2)- and sp(3)-hybridized meso carbon centers. We wer…

Several heteromultimetallic pincer-porphyrin hybrids have been prepared in excellent yields by stepwise metalation of a general precursor, [2H(Br(NCN))(4)], which was designed in such a way so as to guarantee selectivity for either the porphyrin or pincer sites during the metalation steps. First, a metal was introduce…

Photolysis of 1a yields 4a in argon-saturated methanol, whereas 1b is photostable. Laser flash photolysis of 1a in acetonitrile shows formation of biradical 2a (lambda(max) = 340 nm, tau = approximately 60 ns), which undergoes intersystem crossing to form Z-3a (lambda(max) = 380 nm, tau = 270 ns) and E-3a (lambda(max)…
