Abstract We fabricated inorganic–organic hybrid quantum-dot light-emitting-diodes (QD-LEDs) consisting of several types solution-processed n-type oxide electron injection layers (EILs)/quantum-dot (QD) and poly (9-vinylcarbazole) (PVK) blend light emitting layer (EMLs)/4,4-bis(carbazole-9yl)bihpheyl (CBP)/a-NPD/1,4,5,8,9, 11-hexaazatriphenylene-hexacarbonitrile (HAT-CN) hole layer/Al structures...

The synthesis of sugar fatty acid esters (SFAEs) from lignocellulosic biomass and oleic (C18:1) was catalyzed by immobilized-stabilized derivatives Candida antarctica lipase B in a methyl ethyl ketone medium. After steam-explosion pretreatment mixed hardwoods enzymatic hydrolysis at 15%wt solids, xylose glucose were purified/concentrated to mass ratio ~3 1. These sugars superior commercial as t...

Abstract Self‐healable elastomeric materials ( PUA x PU 10– ‐PDMS , = 4, 6, or 8) have been synthesized and utilized as substrates encapsulation films on the top of barrier (deposited polyethylene terephthalate (PET) substrates) to improve their gas properties for packaging applications. Hexa‐layer (HL) assembly consisting two inorganic 2D nanoplatelets, including Mg‐Al layered double hydroxide...

Abstract Polyethyleneimine (PEI)/silica adsorbents have been considered as a promising candidate for post-combustion CO2 capture, but the limited process study has performed on pilot-scale unit. Herein we report 150 h continuous test results using 100 kg sample of silica-PEI fluidized bed The removal efficiency and dynamic sorption capacity were evaluated continuously by changing number variabl...

As the most widely used disposable paper-based diagnostic tool in world, immunochromatographic test strips (ICTS) have occupied more and positions field of rapid diagnosis due to their ease operation affordability. Therefore, development an easily prepared, sensitive, accurate signal reporter is great significance for detection some low-abundance biomarkers clinical diagnosis. Herein, Mg/Fe lay...

Background. Various cationic polymers have been proposed for use as carriers of genetic materials in biotechnology and biomedicine. The poly(2-dimethylamino)ethyl-methacrylate (poly(DMAEMA)) demonstrated high transfection efficiency low cytotoxicity when used a gene delivery system. aim the present study was to evaluate ability poly(DMAEMA)-block-poly(N-vinylpyrrolidone)-co-(butyl-acrylate)-co-...

Chemically ordered, self-assembled FePt nanoparticle arrays with high magnetic anisotropy are considered a candidate medium for data storage beyond 1 Tbit/in. We report comprehensive structural and magnetic studies on thin (3 layer) assemblies of polyethylenimine (PEI) and 4 nm Fe58Pt42 nanoparticles using X-ray diffraction, small angle neutron scattering and magnetometry. We show that prior to...

Propionic acid production from glycerol was studied using Propionibacterium acidipropionici DSM 4900 cells immobilized on polyethylenimine-treated Poraver (PEI-Poraver) and Luffa (PEI-Luffa), respectively. Using PEI-Luffa, the average productivity, yield and concentration of propionic acid from 40 g L(-1) glycerol were 0.29 g L(-1) h(-1), 0.74 mol(PA) mol(Gly)(-1) and 20 g L(-1), respectively, ...

BACKGROUND Several nanoconjugates have been designed to deliver nucleic acids such as small interfering RNA (siRNA) and DNA to cells to study silencing and expression efficacies. In the present study, we prepared novel epithelial cell adhesion molecule (EpCAM) monoclonal antibody conjugated polyethyleneimine (PEI) capped gold nanoparticles (AuNPs) loaded with EpCAM-specific siRNA molecules to k...
