Abstract As cheap and renewable sources, the exploitation of biomass resources was great value in phase change energy storage. In this study, hemp stems were converted into biochars with three-dimensional multi-level anisotropic pores through a temperature-controlled charring process, which used as supports for polyethylene glycol (PEG6000) to form shape-stable composite materials (ss-CPCMs). I...

Bovine serum albumin (BSA), Tween-20, and polyethylene glycol (PEG6000) were added to washed corn stover solids produced by ammonia fiber expansion (AFEX), ammonia recycled percolation (ARP), dilute sulfuric acid (DA), lime, controlled pH, and sulfur dioxide (SO(2)) pretreatments and to untreated corn stover (UT) and pure Avicel glucan prior to adding cellulase supplemented with beta-glucosidas...

Introduction: Macro-creatine kinase (Macro-CK) is a complex with longer half-life that leads to elevation of enzyme activity and analytical errors. We present two cases with macro-CK to picture the problem. The aim of the study was to evaluate and compare different methods using polyethylene glycol (PEG) for screening. Methods: Serum samples (n=39) were analysed using different PEG methods PEG6...

cuals2  chalcopyrite  nanocrystalline  are  synthesized  with  facile method.  the  heat  arrested  solvothermal  method  for  synthesize nanocrystalline  were  investigated.  the  time  duration  of  synthesis, temperature of solution and metal salts to solvent molar ratio can be parameters  that we are  studied. the nanoparticles were  synthesized with cucl, alcl3 and  thiourea (sc(nh2)2) as ...

This work aimed at elucidating the influence of zwitterionic hard segments on the structures and properties of shape memory polyurethanes (SMPUs). A series of zwitterionic SMPUs was successfully prepared with N-methyldiethanolamine (MDEA), 1,3-propanesultone (1,3-PS), 1,6-hexamethylene diisocyanate (HDI) and polyethylene glycol (PEG6000). The influence of MDEA-PS-based zwitterionic hard segment...

The accurate detection of pathogens in environmental matrices, such as sediment, is critical in understanding pathogen fate and behavior in the environment. In this study, we assessed the usefulness of methods for the detection and quantification of Vibrio spp. and norovirus (NoV) nucleic acids in sediment. For bacteria, a commonly used direct method using hexadecyltrimethylammonium bromide (CT...

Background: There are varieties of purification techniques for separation of human plasma proteins such as salting out, ion exchange chromatography, and ethanol fractionation. There are limitations for each method, for example in salting out method, the salt has to be removed in an additional step. Ion exchange chromatography is difficult for scaling up, and plasma fractionation is a time consu...
