Effects of pH and dissolved oxygen on the photodegradation of 17[small alpha]-ethynylestradiol in dissolved humic acid solution

02-Dec-2015 | Dong Ren; Bin Huang; Tingting Bi; Dan Xiong; Xuejun Pan, Journal of Environmental Monitoring, 2015

To probe the mechanisms responsible for pH and dissolved oxygen (DO) affecting the photodegradation of 17α-ethynylestradiol (EE2) in dissolved humic acid (HA) solution, EE2 aqueous solutions with pH values ranging from 3.0 to 11.0 and different DO conditions were irradiated by using a 300 W ...


A light sensitive self-assembled nanogel as a tecton for protein patterning materials

02-Dec-2015 | Tomoki Nishimura; Masahiro Takara; Sada-atsu Mukai; Shin-ichi Sawada; Yoshihiro Sasaki; Kazunari Akiyoshi, Chemical Communication, 2015

A self-assembled nanogel is constructed from light-sensitive cholesteryl pullulan (Ls-CHP) by using photo-labile ortho-nitrobenzyl (o-NB) units. The nanogel-based film is obtained by evaporation of an Ls-CHP nanogel solution. Exposure of the resulting nanogel-based film to light with a mask ...


Nanoparticles self-assembled from multiple interactions: a novel near-infrared fluorescent sensor for the detection of serum albumin in human sera and turn-on live-cell imaging

02-Dec-2015 | Xiaopeng Fan; Qingyuan He; Shiguo Sun; Hongjuan Li; Yuxin Pei; Yongqian Xu, Chemical Communication, 2015

A novel pyrene-conjugated squaraine fluorescent probe SQ-P, which could self-assemble into nanoparticles in aqueous solution through multiple interactions, was designed to selectively detect serum albumin with a turn-on response in the near infrared (NIR) region. More importantly, the probe can ...


Rational Design of a Highly Selective Fluorescent Sensor for L-Histidine Detection in Aqueous Solution

02-Dec-2015 | Yan Qiao; Bin Chen; Yangyang Yang; Xin Wang; yufang xu; Honglin Li, Dalton Transactions, 2015

Computational studies in combination with experimental research were used to design a new rapid, selective and sensitive “turn-on” fluorescent sensor (H3) for L-histidine, which can be first quenched by Ni2+ and then recovered upon addition of His.


An electrochemically aminated glassy carbon electrode for simultaneous determination of hydroquinone and catechol

02-Dec-2015 | Xiuyun Wang; Min Xi; Mengmeng Guo; Fangmeng Sheng; Guang Xiao; Shuo Wu; Shunichi Uchiyama; Hiroaki Matsuura, Analyst, 2015

In this contribution, a very simple and reliable strategy based on the easy modification of a glassy carbon electrode (GCE) by pre-electrolyzing GCE in ammonium carbamate aqueous solution was employed for the simultaneous determination of hydroquinone (HQ) and catechol (CC). Compared with bare ...


Angiotensin II analogs comprised of Pro-Amb ([gamma]-turn scaffold) as angiotensin II type 2 (AT2) receptor agonists

01-Dec-2015 | Ganesh S Jedhe; Amol Kotmale; Pattuparambil R Rajamohanan; Santosh Pasha; G J Sanjayan, Chemical Communication, 2015

We describe herein design, synthesis and conformational investigation of Pro-Amb (proline-3-amino-2-methoxybenzoic acid) incorporated Angiotensin II and its truncated analogues. Solution-state NMR and CD studies suggest γ-turn-like conformation in Pro-Amb analogs in aqueous solution. Furthermore, ...


Thermodynamics of Solvent Interaction with the Metal – Organic Framework MOF-5

01-Dec-2015 | Zamirbek Akimbekov; Di Wu; Carl K. Brozek; Mircea Dinca; Alexandra Navrotsky, Physical Chemistry Chemical Physics, 2015

The inclusion of solvent in metal organic framework (MOF) materials is a highly specific form of guest – host interaction. In this work, the energetics of solvent – MOF-5 interactions has been investigated by solution calorimetry in 5 M sodium hydroxide (NaOH) at room temperature. Solution ...


On the Atomic Structure of Cocaine in Solution

01-Dec-2015 | Andrew James Johnston; Sebastian Busch; Luis Carlos Pardo; Samantha Kim Callear; Philip Biggin; Sylvia McLain, Physical Chemistry Chemical Physics, 2015

Cocaine is an amphiphilic drug which has the ability to cross the blood-brain barrier (BBB). Here, a combination of neutron diffraction and computation has been used to investigate the atomic scale structure of cocaine in aqueous solutions. Both the observed conformation and hydration of cocaine ...


Ligand-free Pd catalyzed cross-coupling reactions in an aqueous hydrotropic medium

01-Dec-2015 | Sanjay N. Jadhav; Arjun S. Kumbhar; Chadrashekhar V. Rode; Rajashri S. Salunkhe, Green Chemistry, 2015

A simple, efficient and ligand-free protocol for the Suzuki–Miyaura reaction and base-free Heck–Matsuda reactions under mild reaction conditions have been developed over palladium supported on activated carbon (Pd/C) in an aqueous hydrotropic solution. The catalyst Pd/C was fully characterized by ...


Solution combustion synthesis of strontium aluminate, SrAl2O4, powders: single-fuel versus fuel-mixture approach

01-Dec-2015 | Robert Ianos; Roxana Istratie; Cornelia Pacurariu; Radu Lazau, Physical Chemistry Chemical Physics, 2015

Solution combustion synthesis of strontium aluminate, SrAl2O4, via the classic single-fuel approach and the modern fuel-mixture approach was investigated in relation to the synthesis conditions, powder properties and thermodynamic aspects. The single-fuel approach (urea or glycine) did not yield ...
