in this paper, we report on the synthesis of cu nanoparticles through a single-precursor route by controlling the growth temperature. selective adsorption of oleylamine on various crystal planes may play an important role in the growth process. the understanding of this self-assembling process will help us develop reliable and reproducible methods to synthesis other three dimensional nanostruct...

Abstract The acene series, an important class of linearly polycyclic aromatic hydrocarbons, are interest owing to their unique physicochemical features. With increase in the number fused benzene rings, acenes display evolution electronic structure and properties. Thus, efforts have been devoted synthesis longer acenes, with dodecacene being longest (12 rings) reported date. However, formation p...

the accurate prediction of protein stability is one of the most challenging goals in protein formulation and delivery. in this study, a gradient rp-hplc method is described for the separation of human growth hormone (hgh) variants as deamidated and oxidized forms. the methodology employed a polymeric poly (styrene-co-divinylbenzene) column and a 1ml/min flow rate of a linear gradient of 0.1% v/...

This study explores the co-deposition of thin polymeric films loaded with nanoparticles for its possible future application as radiation detectors. Thin containing zinc oxide (ZnO) in plasma polymerized n-hexane (PPH) were deposited on silicon substrates using an atmospheric pressure jet (APPJ). Crystalline ZnO produced by wet chemistry, characterized, and injected through aerosol buffer. The p...

Este trabalho descreve um estudo detalhado da oxidação eletroquímica de etanol sobre eletrodos de Ti/(RuO2)(x)Pt(1-x) com várias composições, preparados pelo método de precursores poliméricos. Os resultados obtidos usando voltametria cíclica e cronoamperometria mostraram que a melhor composição dos eletrodos de Ti/(RuO2)(x)Pt(1-x) para os processos de oxidação do CO e do etanol é Ti/(RuO2)(0.5)...

In this work, the copolymer-based synthesized Cysteine-loaded nanocarriers prepared by a routine protocol, coprecipitation method. It is the first report to investigate the neuroprotective potential and biocompatibility of Cysteine derivatives loaded into poly(ethylene glycol)-block-poly(ε−caprolactone) methyl ether (PEG-b-PCL). The average size of the polymeric/empty NCs was 89 nm and for poly...

acute lymphoblastic leukemia (all) is the most prevalent hematological malignant tumor during childhood. unilateral infiltration into the gums is less prevalent and more often observed in the aml type. a 12-year-old girl with symptoms of pain and swelling in the buccal vestibule and also at the posterior part of the right palate of the maxilla was referred to a private dental office. the patien...
