A novel polyfunctional neutral organophosphorus compound, 2-(diphenylphosphoryl)-N,N-diethyl-3-(1-phenyl-1H-1,2,3-triazol-4-yl)propanamide (I), was synthesized and studied as an extractant for Pd(II), Ln(III), U(VI), and Th(IV) from HNO3 solutions. The influence of aqueous and organic phases on the extraction efficien…
We investigated the photocatalytic inactivation of free Escherichia coli and E. coli attached to carbon particles using granulated activated carbon filter effluent as a water sample. The inactivation rates of both free and attached E. coli exposed to UV/TiO2 were higher than that using UV irradiation alone. However, a…
The present paper describes a first step taken at the Paul Scherrer Institut in the development of a new multi-physics platform for reactor analysis. Such platform is based on the finite-volume software OpenFOAM and aims at a tightly coupled description of neutron transport, thermal mechanics and fluid dynamics. For t…
Liquid lead or lead-based alloy is a potential candidate coolant for fast reactors and ADS subcritical reactors because of its many unique nuclear, thermal-physical and chemical attributes. Chinese Academy of Sciences (CAS) had launched an engineering project to develop ADS system and lead-based reactors. Series CLEAR…
Crystalline InAs films have been prepared directly at room temperature through a new electrochemically induced alloying method by controllably reducing As 2 O 3 dissolved in an alkaline aqueous solution at an indium (In) foil electrode. Steady-state Raman spectra, transmission electron microscopy, and selected area el…
Top-down synthesis of 2D materials from a parent 3D zeolite with subsequent post-synthetic modification is an interesting method for synthesis of new materials. Assembly, disassembly, organisation, reassembly (ADOR) processes towards novel materials based on the zeolite UTL are now established. Herein, we present the…
Subconjunctival/episcleral, intrascleral, and suprachoroidal routes of drug delivery for treatment of posterior segment eye diseases have become more feasible and popular in the past few years. These routes have the advantage of bypassing the main barriers to topical drug penetration, the ocular surface epithelium, th…
We present Raman investigations on lysozyme/trehalose/glycerol solutions at low water content, from room temperature up to the occurrence of the protein thermal denaturation. We studied the Amide I band and the low-frequency spectrum as a function of the glycerol content. The former allows us to monitor the protein un…
Molecular dynamics simulations are used to investigate the behaviour of liquid acetonitrile confined within nm diameter silica pores. Different approaches for characterising the liquid structure in the pores are examined and compared. The effect of surface chemistry on the liquid layering at the pore interface is disc…
A single barrier dielectric barrier discharge tube of quartz with multi-strip Titanium-Gold (Ti-Au) coatings have been developed and utilized for ultraviolet-B (UV-B) radiation production peaking at wavelength 308 nm. The observed radiation at this wavelength has been examined for the mixtures of the Xenon together wi…
Abstract A new in‐situ NMR strategy (termed CLASSIC NMR) for mapping the evolution of crystallization processes is reported, involving simultaneous measurement of both liquid‐state and solid‐state NMR spectra as a function of time. This combined strategy allows complementary information to be obtained on the evolution…
New thiophene derivatives (THs) are prepared and proposed here as new photoinitiators in combination with an iodonium salt for the cationic polymerization of vinylethers. They contain electron donor and electron acceptor (D–A) moieties and exhibit red‐shifted absorption spectra. They allow the use of a long‐wavelength…
Reaction of CO2 with a Pd(I)-Pd(I) dimer supported by amido/bis(phosphine) pincer PNP ligands produces free CO in the presence of Me3SiCl and Me3SiOTf.
A common technique for the preparation of polymeric nanoparticles (NPs) from preformed polymers is the emulsification solvent evaporation (ESE) method. However, the particle size of such carriers can typically not reduced below 100 nm. A bimodal distribution of particle size when applying ESE to the preparation of eth…
Kryptopyrrole (2,4-dimethyl-3-ethylpyrrole) was acylated with, for example, benzoyl chloride to afford 2-benzoyl-3,5-dimethyl-4-ethylpyrrole (L(1)H). With SiCl4 this ligand reacts under liberation of HCl and formation of the complex L(1)2SiCl2. In related reactions with HSiCl3 or H2SiCl2, the same chlorosilicon comple…
We have studied the structural and electronic properties of YPd2Sn in the Heusler structure using a generalized gradient approximation of the density functional theory and the ab initio pseudopotential method. The electronic results indicate that the density of states at the Fermi level is primarily derived from Pd d…
A mononuclear iron(II) complex, Et4N[Fe(C10H6NO2)3], coordinated by three 1‐nitroso‐2‐naphtholate ligands in a fac‐N3O3 geometry, was initiated to catalyze the direct hydroxylation of aromatic compounds to phenols in the presence of H2O2 under mild conditions. Various reaction parameters, including the catalyst dosage…
Methanogenic archaea lack cysteinyl-tRNA synthetase; they synthesize Cys-tRNA and cysteine in a tRNA-dependent manner. Two enzymes are required: Phosphoseryl-tRNA synthetase (SepRS) forms phosphoseryl-tRNA(Cys) (Sep-tRNA(Cys)), which is converted to Cys-tRNA(Cys) by Sep-tRNA:Cys-tRNA synthase (SepCysS). This represent…
Solid-state quantum dot sensitized solar cells (QDSSCs) were fabricated with zinc sulfide quantum dots (ZnS QDs), which served as the light absorber and the recombination blocking layer simultaneously. ZnS QDs were prepared successfully by a novel successive ionic layer adsorption and reaction technique based on dip-c…
The performance of InGaN/GaN light-emitting diodes (LEDs) fabricated using NH 3 was varied by intentionally adding H 2 O, O 2 , or CO. The oxygen concentration in the active layer varied with the type of impurity, which was related to the binding energy of the impurity. When a small amount of oxygen was incorporated i…
