The yield and purity of synthetic peptides were greatly related to the amino acid protection and activation during the synthesis process. Therefore, the amino acid protection and activation are the most important steps in peptide synthesis. By using tetrahydrofuran as the solvent, 9-fluorenylmethoxycarbonyl as protection group, 2-(7-azobenzotriazol-1-yl)-N,N,N',N'-tetramethyluronium hexafluorop...
Atomic layer deposition (ALD) has been considered as an efficient method to deposit high quality and uniform thin films of various electron transport materials for perovskite solar cells (PSCs). Here, the effect sequence in ALD process aluminum-doped zinc oxide (AZO) on performance stability PSCs is investigated. Particularly, surface AZO film terminated by diethylzinc (DEZ)/H2O (AZO-1) or trim...
In this study, indium-tin oxide (ITO)/Al-doped zinc oxide (AZO) composite films were fabricated by pulsed laser deposition and used as transparent contact layers (TCLs) in GaN-based blue light emitting diodes (LEDs). The ITO/AZO TCLs were composed of the thin ITO (50 nm) films and AZO films with various thicknesses from 200 to 1000 nm. Conventional LED with ITO (200 nm) TCL prepared by E-beam e...
We synthesized a porous twofold interpenetrated MOF [Zn(2)(NDC)(2)(1)] (coined CAU-5) using 3-azo-phenyl-4,4'-bipyridine (1), 2,6-naphthalenedicarboxylic acid, and Zn(NO(3))(2)·6H(2)O. The azo-functionality protrudes into the pores, and can be switched, by irradiation with UV light (365 nm), from the thermodynamically stable trans-isomer to the cis-isomer. Back-switching was achieved thermally ...
The human platelet receptors for normal, nonimmune IgG and its F(ab')2 and Fc fragments were studied by the use of a cleavable, bifunctional, photoactivable, 125I-labeled cross-linking agent. Derivatization of the ligands with N-[4-(p-azido-m-[125I]iodophenylazo) benzoyl]-3-aminopropyl-N'-oxysuccinimide ester (Denny-Jaffe reagent) reduced their binding to platelets by greater than or equal to 2...
Ultrathin (submicrometer) organic films of specified index of refraction are constructed by the sequential deposition of self-assembled zirconium phosphonate (ZP) molecular monolayers that contain two Merent bisphosphonate ions, 1,lO-decanediylbis(phosphonate) (DBP) and 4,4azobis[(p-phenylene)methylenelbis(phosphonate) (AZO). By varying the ratio of DBP to AZO monolayers in the ZP multilayer fi...
Since the early observations of Kellner (1936) and Fuller (1937), who demonstrated that p-aminobenzenesulfonamide (sulfanilamide) is formed in animal tissues when prontosill or prontosil soluble2 (neoprontosil3) is administered by mouth, and the studies by Domagk (1935), Colebrook and Kenney (1936), and Colebrook, Buttle, and O'Meara (1936), wherein they were unable to demonstrate an antibacter...
We report a new strategy for shape control over the synthesis of gold nanoparticles (AuNPs) by using a photoresponsive surfactant based on a modified seed growth method. Owing to photoresponsive properties of the azo group, the designed surfactant, N(1),N(3),N(5)-tris[(4'-azobenzene-4-sulphonic acid)phenyl]benzene-1,3,5-tricarboxamide, exhibits a distinctive molecular configuration under light ...
The data reported in this paper are complementary to the characterization of 4-(phenylazo)-benzoyl-2,2,6,6-tetramethylpiperidine-1-oxyl radical (AzO-TEMPO) and of the 4-(2-thienylazo)-benzoyl-2,2,6,6-tetramethylpiperidine-1-oxyl radical (ThiO-TEMPO) before and after their grafting to two polyethylene matrices (a copolymer ethylene/α-olefin (co-EO) and a high density polyethylene (HDPE)). Partic...
