acute renal failure is one of the side effects while using intravenous immunoglobulins. this complication is also observed with iodinated contrast media. herein, we describe a patient with acute renal failure who received intravenous immunoglobulins and iodinated contrast media concomitantly. both drugs are responsible for osmotic nephrosis. the same effect on renal cells may explain a synergis...

The catalytic degradation of chlorinated volatile organic compounds (CVOCs) at low temperatures is a great challenge. In this work, Pt-Co/HZSM-5 ternary catalysts were synthesized and used for the oxidation dichloromethane (DCM). By adding only trace amounts Pt (0.01 wt. %), catalyst exhibits better CO2 yield lower by-product than Co/HZSM-5 catalyst. Besides, it maintained stable activity least...

Amino acid modifications of the Thermobifida fusca Cel9A-68 catalytic domain or carbohydrate binding module 3c (CBM3c) were combined to create enzymes with changed amino acids in both domains. Bacterial crystalline cellulose (BC) and swollen cellulose (SWC) assays of the expressed and purified enzymes showed that three combinations resulted in 150% and 200% increased activity, respectively, and...

CO2-assisted gasification of carbon-based waste materials is one the processes that both utilises carbon chemicals and produces CO, which a highly sought after raw material. In this work, we aimed at finding clarifying synergistic effects simultaneous potassium Fe, Co, or Ni-driven catalysis. To reveal behaviour such systems, series with different loadings fixed second metal loading 5 wt.% was ...

Zeolite fibers have attracted growing interest for a range of new applications because of their structural particularity while maintaining the intrinsic performances of the building blocks of zeolites. The fabrication of uniform zeolite fibers with tunable hierarchical porosity and further exploration of their catalytic potential are of great importance. Here, we present a versatile and facile ...

Here, a novel N,B-doped graphene aerogel, abbreviated as N,B-GA, was obtained via a two-step approach and served as a metal-free catalyst for the oxygen reduction reaction (ORR). This two-step method involved a hydrothermal reaction and a pyrolysis procedure, guaranteeing the efficient insertion of the heteroatoms. The resulting three-dimensional (3D) N,B-GA obtained at pyrolysis temperature of...

Abstract The study investigates tert- butoxy alkanols (otherwise defined as polyol butyl ethers) that have vicinal and hydroxy groups in their molecules from the perspective of usability oxygenated additives for motor gasoline. A series propylene glycol mono- ether (PTBE) glycerol di- (di-GTBE) samples were prepared: PTBE by direct acid-catalytic alkylation diols with butanol, di-GTBE epichloro...

Though s-block organometallics are indispensable tools in synthetic chemistry, their impact homogeneous catalysis has been small compared to that for transition metals. Surprisingly, however, Group 1 and 2 compounds have recently utilised hydroelementation catalysis. For example, transfer hydrogenation of alkenes alkanes catalysed by (Ca, Sr, Ba) bis-hexamethyldisilazides (HMDS), though reactio...

Non‐noble‐metal‐based and earth‐abundant electrocatalysts have been extensively investigated for the hydrogen evolution reaction (HER). However, they still suffer from large Tafel slopes high overpotentials, resulting in inferior HER catalytic activity. Herein, a novel, cost‐effective, electrochemically stable catalyst is presented by growing ultrasmall CoSe 2 nanoparticles on MoS nanofilms usi...
