Solid-state photovoltaic cells based on robust metal-organic frameworks (MOFs), MIL-125(Ti), MIL-125(Ti)-NH2, UiO-67, Ru(bpy)2-UiO-67, (bpy 2,2‘-bipyridine) as active components and spiro-MeOTAD (MeOTAD 2,2‘,7,7‘-tetrakis[N,N-di(p-methoxyphenyl)amino]-9,9′-spirobifluorene) hole transporting layer have been prepared., The response of this material increases in the presence bathochromic −NH2 grou...

Class II actin genes usually specify a polypeptide with a Met-Cys-Asp NH2 terminus, whereas the actin itself begins with an acetyl (Ac)-Asp(Glu). Previous studies with Drosophila actin showed that the first detectable intermediate is one with an Ac-Cys NH2 terminus which is subsequently cleaved in a novel reaction to expose the Asp. The initiator Met was probably removed early in translation as...

Purpose To determine the role of protease-activated receptor-2 (PAR-2) in cornea infected by Aspergillus fumigatus. Methods PAR-2 was tested in normal and infected corneas of C57BL/6 mice. Mice corneas were infected with A. fumigatus with or without pretreatment of PAR-2 antagonist (FSLLRY-NH2). Polymorphonuclear neutrophilic leukocytes (PMNs) were stimulated with 75% ethanol-killed A. fumiga...

A novel magnetic solid phase extraction based on mercaptophenylboronic acid (MPBA)-functionalized Fe3O4-NH2@Au nanomaterial (Fe3O4-NH2@Au-MPBA) was developed for selective separation and enrichment of catecholamines (including dopamine, norepinephrine adrenaline). Fe3O4-NH2@Au-MPBA nanoparticles were achieved by self-assembly-anchoring MPBA molecules the surface nanocomposites, which synthesize...

Colloidal dye-sensitized photocatalysis is a promising route toward efficient solar fuel production by merging properties of catalysis, support, light absorption, and electron mediation in one. Metal-organic frameworks (MOFs) are host materials with modular building principles allowing scaffold property tailoring. Herein, we combine these two fields compare porous Zr-based MOFs UiO-66-NH2(Zr) U...

Metal organic frameworks (MOFs) have attracted great interest in photocatalysis, but their activity is hampered by the issue of severe carrier recombination. Here, through a carboxyl group assisted coordination route, MXene decorated with groups provides chelation sites enabling UiO-66-NH2(Zr/Ti) (UZT) to fabricate tightly connected UiO-66-NH2(Zr/Ti)/carboxyl-functionalized (UZT/CFMX) heterostr...

LaMnO3 with perovskite structure is a SCR de-NOx catalyst good performance at low temperatures. In this paper, the reaction process on 010 surface of was studied by DFT method, to guide development catalysts and their effective application. The results obtained through research indicate that both E-R L-H mechanisms exist surface. NH3 molecule can be absorbed L acid then oxidized lattice oxygen ...

A simple protocol was used to prepare amine functionalized cellulose nanocrystals (CNC-NH2). In the first step, epichlorohydrin (EPH) was reacted with ammonium hydroxide to produce 2-hydroxy-3-chloro propylamine (HCPA). In the next step, HCPA was grafted to CNC using the etherification reaction in an organic solution media. Various reaction parameters, such as time, temperature, and reactant mo...

Two peptides that crossreact with an antiserum raised against Phe-Met-Arg-Phe-NH2 were purified from bovine brain extract. Their structures were determined to be Ala-Gly-Glu-Gly-Leu-Ser-Ser-Pro-Phe-Trp-Ser-Leu-Ala-Ala-Pro-Gln-Arg-Phe- NH2 and Phe-Leu-Phe-Gln-Pro-Gln-Arg-Phe-NH2. The sequences were determined by gas-phase sequencing, except for the COOH-terminal phenylalaninamides. These were as...

The phase equilibriums of the ternary system KCl-(NH2)2CO-H2O at 303.15 K, 323.15 333.15 and 343.15 K were studied using isothermal dissolution equilibrium method, in which composition solid was determined by Schreinemaker’s wet residue method X-ray diffraction (XRD) method. It found that is a simple cosaturated system, without formation neither double salt nor solution. Wilson NRTL models empl...
