Abstract Kinetics of oxidation of L‐cysteine by CoIII and FeIII complexes based on α‐ and γ‐diimine Schiff base ligands were studied in aqueous solution. Pairs of trans and cis isomers of the metal complexes were used in the studies. Kinetic measurements were performed at 25 °C and constant pH and ionic strength under…
Abstract This investigation highlights the adhesion performance of carbon fiber‐ and glass fiber‐reinforced polyphenylene sulfide when joined by high‐performance neat epoxy adhesive and nanofilled epoxy adhesive. A significant increase in the surface energy of these materials is observed after the surface modification…
A chiral charge-transfer (CT) complex was formed using achiral 9,10-bis(3,5-dihydroxyphenyl)anthracene (BDHA) as an electron donor and achiral 1,1′-dimethyl-4,4′-bipyridinium dichloride (MVCl2) as an electron acceptor. This chiral CT complex can include n-alkyl alcohol molecules as guests. On the other hand, when 1,1′…
Abstract In this work, the effective degradation of Acid Red B dyes in aqueous solution was realized in various ultrasound (US)/TiO2/oxidant (KIO4, KIO3 and K2S2O8) systems. In addition, the degradation efficiencies of Acid Red B in US/TiO2/oxidant systems for a variety of oxidants were compared. The results revealed…
A natural leaf is a synergy of elaborated structures and functional components, producing a highly complex machinery for photosynthesis in which light harvesting, photoinduced charge separation, and catalysis modules combine to capture solar energy and split water into oxygen and “hydrogen” efficiently. On p. 951, Ton…
We report measured and calculated results for elastic scattering of low-energy electrons by ethyl vinyl ether (ethoxyethene), a prototype system for studying indirect dissociative attachment processes that may play a role in DNA damage. The integral cross section displays the expected ${\ensuremath{\pi}}^{*}$ shape re…
Rice (Oryza sativa L.) Os4BGlu12, a glycoside hydrolase family 1 beta-glucosidase (EC 3.2.1.21), was expressed as a fusion protein with an N-terminal thioredoxin/His(6) tag in Escherichia coli strain Origami B (DE3) and purified with subsequent removal of the N-terminal tag. Native Os4BGlu12 and its complex with 2,4-d…
We have used reactive force field (ReaxFF) to investigate the mechanism of interaction of alanes on Al(111) surface. Our simulations show that, on the Al(111) surface, alanes oligomerize into larger alanes. In addition, from our simulations, adsorption of atomic hydrogen on Al(111) surface leads to the formation of al…
The wetting behavior of ethylene adsorbed on MgO(100) was investigated from 83-135 K using high resolution volumetric adsorption isotherms. The results are compared to ethylene adsorption on graphite, a prototype adsorption system, in an effort to gain further insight into the forces that drive the observed film growt…
The cover shows a schematic illustration of patterned colloidal photonic crystals with different bandgap positions. When an unknown light source impinges on the patterned photonic crystals, the light information can be identified from the reflection intensity profile of the constituent photonic crystals. The two optic…
Magneto-optical measurements on ruby under high-pressure conditions provided direct determination of the trigonal crystal field acting at the ${t}_{2g}$ orbitals of ${\text{Cr}}^{3+}$ in ${\text{Al}}_{2}{\text{O}}_{3}$ $({\text{CrO}}_{6})$ and its dependence with pressure. The correlation study between the measured tr…
A(1)A(o) ATP synthases are the major energy producers in archaea. Subunit E of the stator domain of the ATP synthase from Pyrococcus horikoshii OT3 was cloned, expressed and purified to homogeneity. The monodispersed protein was crystallized by vapour diffusion. A complete diffraction data set was collected to 3.3 A r…
Phosphoglucose isomerase (PGI) is a key enzyme in glycolysis and glycogenesis that catalyses the interconversion of glucose 6-phosphate (G6P) and fructose 6-phosphate (F6P). For crystallographic studies, PGI from the human malaria parasite Plasmodium falciparum (PfPGI) was overproduced in Escherichia coli, purified an…
Abstract CeCu5 is a Kondo lattice in which antiferromagnetic ordering occurs at 3.9 K. Substituting Cu with Al to achieve CeCu3Al2 results in amplifying the Kondo interaction through addition of conduction electrons, and simultaneously driving the magnetic order down to beyond detection. We present results of specific…
In a previous work ( J. Cryst. Growth 2009, 311, 2590), direct growth of a fcc architecture of Cr 2 O 3 phase onto (001)TiO 2 substrates has been obtained by photolysis of CrO 2 Cl 2 in a three-dimensional interference field of UV laser light. This growth includes a step of CrO 2 -to-Cr 2 O 3 transformation which is c…
Abstract We performed extensive density functional calculations on various metallofullerene complexes and their polyanions to gain insight into novel η1 and η2[6:5] metal (M)–C60 bonding modes. For LnMC60 (L = ligand), the η1 mode is calculated to be the most stable, followed by η2[6:5] and η2[6:6] for –3 anions, in c…
Architectural fabrics are translucent, lightweight and flexible allowing impressive forms to be achieved unlike any other material.However in order to create the required double curved structural form, flat fabrics must undergo shear deformation during installation.Due to the woven nature of architectural fabrics cont…
The need for new and effective/efficient antibacterial therapeutics and diagnostics is necessary if we want to be able to maintain and improve the protection against pathogenic bacteria. Bacteria are becoming increasingly resistant to traditionally used antibiotics and as a result are a major health concern. The numbe…
UNLABELLED: The ever increasing number of structural biological data calls for robust and efficient software for analysis. Easy Structural Biology Template Library (ESBTL) is a lightweight C++ library that allows the handling of PDB data and provides a data structure suitable for geometric constructions and analyses.…
This study was performed to determine the effect of boric acid treatment upon the decay resistance and mechanical properties of poplar wood. Test specimens were prepared from poplar wood (Populus nigra L.) to meet ASTM D 143-94 and BS 838:1961 requirements. Samples were impregnated with boric acid solution (0.5, 1, an…
