Label‐Free, Electrochemical Quantitation of Potassium Ions from Femtomolar Levels
Chemistry - An Asian Journal - Tập 10 Số 10 - Trang 2169-2175 - 2015
Bicheng Zhu, Marsilea A. Booth, Han Young Woo, Justin M. Hodgkiss, Jadranka Travaš-Sejdić
AbstractIn this communication, a label‐free and sensitive electrochemical method to detect potassium ions is proposed. The conducting polymer polypyrrole was used as both an anchor for the probe and a transducer of the detection event. A K+‐specific G‐rich aptamer was applied as a recognition element, which folded into the G‐quadruplex structur...... hiện toàn bộ
Photoelectrochemical Hydrogen Peroxide Production from Water on a WO3/BiVO4 Photoanode and from O2 on an Au Cathode Without External Bias

Kojiro Fuku, Yuta Miyase, Yugo Miseki, Takashi Funaki, Takahiro Gunji, Kazuhiro Sayama
AbstractThe photoelectrochemical production and degradation properties of hydrogen peroxide (H2O2) were investigated on a WO3/BiVO4 photoanode in an aqueous electrolyte of hydrogen carbonate (HCO3−). High concentrations of HCO3... hiện toàn bộ
Cu‐catalyzed Synthesis of Quinolines by Dehydrogenative Reaction of 2‐Aminobenzyl Alcohol and Ketones: A Combined Experimental and Computational Study
Chemistry - An Asian Journal - Tập 17 Số 22 - 2022
Tuan Minh Ha, Nina Thi Nguyen, Ngoc Huyen Tran, Quoc Viet Ho, Nguyễn Thị Son, Vân Hà Nguyễn, Hien Nguyen, Dang Van Do, Tran Quang Hung, Binh Khanh, Tuan Thanh Dang
AbstractQuinoline derivatives are important moieties in bioactive molecules and advanced materials. However, an efficient strategy to synthesize quinoline derivatives remains challenging. Herein, we describe an efficient and practical method for the synthesis of quinolines by Cu‐catalyzed cyclization of 2‐amino benzyl alcohol with ketones (or secondary alcohols) vi...... hiện toàn bộ
Photocatalytic Advanced Oxidation Processes for Water Treatment: Recent Advances and Perspective
Chemistry - An Asian Journal - Tập 15 Số 20 - Trang 3239-3253 - 2020
Huan Liu, Chengyin Wang, Guoxiu Wang
AbstractNowadays, an ever‐increasing variety of organic contaminants in water has caused hazards to the ecological environment and human health. Many of them are persistent and non‐biodegradable. Various techniques have been studied for sewage treatment, including biological, physical and chemical methods. Photocatalytic advanced oxidation processes (AOPs) have rec...... hiện toàn bộ
High‐Performance Dye‐Sensitized Solar Cells Based on Phenothiazine Dyes Containing Double Anchors and Thiophene Spacers
Chemistry - An Asian Journal - Tập 9 Số 1 - Trang 357-366 - 2014
Wei‐I Hung, You‐Ya Liao, Chih‐Yu Hsu, Hsien‐Hsin Chou, Ting‐Hui Lee, Wei‐Siang Kao, Jiann T. Lin
AbstractA series of new push–pull phenothiazine‐based dyes (HL1, HL2, HL3, HL4) featuring various π spacers (thiophene, 3‐hexylthiophene, 4‐hexyl‐2,2′‐bithiophene) and double acceptors/anchors have been synthesized, characterized, and used as sensitizers for dye‐sensitized s...... hiện toàn bộ
Structural modulation induced by cobalt‐based ionic liquids for enhanced thermoelectric transport in PEDOT:PSS
Chemistry - An Asian Journal - Tập 16 Số 18 - Trang 2740-2744 - 2021
Yannan Lu, Aoyun Wu, Chenwei Sha, Xiao‐Chun Hang, David James Young
AbstractPoly(3,4ethylenedioxythiophene):poly(4‐styrenesulfonate) (PEDOT:PSS) has been intensively studied for its thermoelectric applications. Structural modulation to improve crystalline ordering, chain conformation and film morphology is a promising way to decouple the trade‐off between conductivity and Seebeck coefficient and thus improve the thermoelectric powe...... hiện toàn bộ
Ir(III)‐Catalyzed C7‐Position‐Selective Oxidative CH Alkenylation of Indolines with Alkenes in Air
Chemistry - An Asian Journal - Tập 9 Số 5 - Trang 1257-1260 - 2014
Shiguang Pan, Takayuki Wakaki, Naoto Ryu, Takanori Shibata
AbstractAn efficient method for C7‐position‐selective alkenylation of N‐substituted indolines with alkenes is reported. Various 7‐alkenylindolines were obtained in moderate to excellent yields in air in the presence of catalytic amounts of [Cp*IrCl2]2, AgOTf, and Cu(OAc)2. The...... hiện toàn bộ
Removal of Acid Orange G Azo Dye by Polycation‐Modified Alpha Alumina Nanoparticles
Chemistry - An Asian Journal - Tập 18 Số 17 - 2023

AbstractHighly positively charged poly(vinyl benzyl trimethylammonium chloride) (PVBMA) was successfully synthesized with approximately 82% of yield. The PVBMA was characterized by the molecular weight (Mw) of 343.45 g mol−1and the molecular weight distribution, (Đ) of 2...... hiện toàn bộ
Supramolecular Tilt Chirality Derived from Symmetrical Benzene Molecules: Handedness of the 21 Helical Assembly
Chemistry - An Asian Journal - Tập 2 Số 2 - Trang 230-238 - 2007
Akira Tanaka, Ichiro Hisaki, Norimitsu Tohnai, Mikiji Miyata
AbstractAchiral molecules can form aggregates with chirality. This depends on the relative position of the molecules, in other words, the tilt of the molecules (so‐called supramolecular tilt chirality). In this paper, we describe supramolecular chirality appearing in a 21 column composed of symmetrical benzene molecules, which is formed in the ...... hiện toàn bộ
