Chemistry &Biodiversity, EarlyView.ABSTRACT The escalating global challenge of antibiotic resistance amid rising oxidative stress emphasizes the critical necessity for innovative antimicrobial strategies. This study, reported synthesis of Schiff base ligand, (Z)‐2‐[(4‐nitrobenzylidene)amino]phenol (HL), derived from condensation between 2‐aminophenol and 4‐nitrobenzaldehyde, and it Co ...

Dynamic phenomena in superconducting oxides by ESR [PDF]
, 1994 Dynamic electron spin resonance (ESR) measurements compare the paramagnetic and antiferromagnetic (AF) properties of superconducting oxides in the range 4 K to room temperature, at 8 MHz and 9.36 GHz. Two are derivatives of YBa2Cu30 7: 1: Nd(Nd0.05Ba0.95

From Hydroborations Catalyzed by Sn(II) Cations to Photoluminescent Boronic Esters
ChemCatChem, EarlyView.The N‐coordinated Sn(II) cation was found as efficient catalyst for the hydroboration of a broad range of substrates including substituted benzaldehydes, heterocyclic carbaldehydes, aliphatic aldehydes as well as ketones. It was also used in large‐scale hydroboration reactions of pyridine‐substituted carbaldehydes, which were characterized by NMR ...

ChemistryEurope, EarlyView.It is shown that pnictogenium ions [R2E]+ (E = P, As, Sb, Bi) either insert into the E′E″ bond or coordinate to the phosphorus lone‐pair of the tetrahedral heterodipnictogen complexes [{CpMo(CO)2}2(μ,η2:2‐E′E″)] (E ≠ E″ = P, As, Sb). Reactivity studies of the obtained three‐membered interpnictogen chains with another tetrahedrane unit allowed for the ...

Theoretical Study of Heteroatom Resonance-Assisted Hydrogen Bond: Effect of Substituent on π-delocalization [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2010 The concept of Resonance Assisted Hydrogen Bond (RAHB), which usually occurs in b diketons, has a remarkable role in chemistry. These molecules, which contain heteroatom particularly O and N, are species with biological interest in protein folding and ...

ChemistryEurope, EarlyView.Ligand‐to‐metal charge transfer photocatalysis and benzenethiol‐based hydrogen atom transfer catalysis are integrated to develop an iron‐promoted anti‐Markovnikov hydrochlorination of alkenes with hydrochloric acid. The results of experimental and theoretical analyses provide fundamental insights into reactivity control, paving the way for future ...

Combination therapy with normobaric oxygen (NBO) plus thrombolysis in experimental ischemic stroke
BMC Neuroscience, 2009 Background The widespread use of tissue plasminogen activator (tPA), the only FDA-approved acute stroke treatment, remains limited by its narrow therapeutic time window and related risks of brain hemorrhage.
