This article is devoted to the use in concrete of polymeric reagent POLY-ANS, developed based on production waste polyacrylonitrile fibers. The results effect capillary absorption concrete, which contributes provision high resistance cement saline environments, are given.

Deoxygenative upgrading of 5-hydromethylfurfural (HMF) into valuable chemicals has attracted intensive research interest in recent years, with product selectivity control remaining an important topic. Herein, TiO2 supported gold catalysts coated a thin N-doped porous carbon (NPC) layer were developed via polydopamine-coating-carbonization strategy and utilized for pathway-specific conversion HM...

The development of novel approaches to the remotion pharmaceuticals in wastewater is a subject concern due their effect on living beings and environment. Advanced oxidation processes use relevant catalysts are feasible treatment alternatives that require further development. suitable heterogeneous necessity. This work proposes synthesis an iron catalyst deep eutectic solvent (Fe-DES) composed c...

Here we report a modified peptide reagent useful for the rapid, native elution of protein complexes containing a Protein-A-tagged component. We tested this reagent for the elution of tagged endogenous protein complexes from yeast (Nup53p/Nup170p dimer; Nup1p/Kap95p/Kap60p trimer; pentameric GINS complex) and bacteria (RNAP holoenzyme). The majority of the affinity-isolated material is released ...

A modified toluidine blue O (TBO) stain for Pneumocystis carinii cysts was evaluated with regard to the influence of (i) the age and extent of use of the sulfation reagent, (ii) the source of TBO, (iii) the TBO content of the staining solution, and (iv) the amount of TBO present in the alcohol wash solutions. All TBOs evaluated, except for a new TBO obtained from Roboz Surgical Instrument Co., ...

In the flotation process, the concentrate grade and the tailing grade are crucial technical indices which reflect the product quality and efficiency. There are strong nonlinearity and uncertainty in such technical indices dynamic behaviors, which can hardly be described using accurate mathematical model. The technical indices which cannot be measured online continuously vary with boundary condi...

The activated partial thromboplastin time (aPTT) is widely used as a screening coagulation test and for monitoring unfractionated heparin therapy. Various commercial reagents are available, with different performance characteristics, particularly responsiveness to the lupus anticoagulant (LA). Because aPTT reagent selection significantly affects the interpretation of results, we reviewed Colleg...
