Unravelling the role of polyols with increasing carbon chain length and OH groups on phase transition behavior of PNIPAM

03.07.2018 | Payal Narang; Pannuru Venkatesu, New Journal of Chemistry, 2018

In advance field of pharmaceutical, agricultural and biomedical research, thermoresponsive polymers (TRPs) are potential and candidates which shows their conformational transition at a particular temperature. The conformational transition in TRPs depends on their intermolecular interactions with ...


Cytotoxicity studies of selected cadmium-based quantum dots on 2D vs. 3D cell cultures

03.07.2018 | Ilona Grabowska-Jadach; Agnieszka Zuchowska; Marta Olesik; Marcin Drozd; Mariusz Pietrzak; Elzbieta Malinowska; Zbig ..., New Journal of Chemistry, 2018

In our work, the cytotoxicity of selected, cadmium-based quantum dots with various surface architectures was studied on 3D spheroids. A specially designed microsystem as a tool for three-dimensional cell culture and nanoparticle toxicity evaluation was used for this aim. Two types of hydrophilic ...


One-pot synthesis of highly fluorescent Fe2+-doped carbon dots for dual-emissive nanohybrid to detection of zinc ions and histidine

03.07.2018 | Bingyan Han; Tingting Peng; Mingbo Yu; Chen Chi; Ying Li; Xixi Hu; Gaohong He, New Journal of Chemistry, 2018

Metal ions-doping is paid a little attention comparing with the nonmetallic-element doping to improve the fluorescence intensity of carbon dots (CDs). Herein, Fe2+-doped CDs was facilely synthesized at 80 °C instead of hydrothermal method for the first time. Fe2+ was confirmed to be the only ...


Facile in situ fabrication of oriented titania submicrorods embedded into a superelastic nickel-titanium alloy fiber substrate and their application in solid-phase microextraction

03.07.2018 | Feifei Wang; Zhuo Wang; Ziyi Wang; Rong Zhang; Junliang Du; Xin-zhen Du, New Journal of Chemistry, 2018

A nickel-titanium oxide (NiO/TiO2) coating was in situ grown on a nickel-titanium alloy (NiTi) fiber substrate by anodic oxidation. After annealing, a uniform and dense Ni-free coating of rutile phase TiO2 submicrorods (TiO2SRs) was formed. In particular, TiO2SRs were embedded into the NiTi fiber ...


A benzimidazole-based highly selective colorimetric and far-red fluorometric pH sensor for intracellular imaging

03.07.2018 | Tao Gong; Rong Li; Yangyang Yuan; Baofeng Yu; Hong Zhao; Zhizhen Liu; Rui Guo; Dan Su; Wenting Liang; Chuan Dong, New Journal of Chemistry, 2018

A turn-on fluorescent probe (E)-4-(2-(1H-benzo[d]imidazol-2-yl)vinyl)-N,N-diphenylaniline (BVD) was facilely synthesized via the ethylene bridging of triphenylamine and benzimidazole. The probe exhibited strong emission enhancement in the vis-NIR fluorescence region at 605 nm with pKa 4.14 and ...


Effects of Nd-modification on the activity and SO2 resistance of MnOx/TiO2 catalyst for low-temperature NH3-SCR

03.07.2018 | Wenkui Zhang; hongfeng Chen; Yang Xia; Ruyi Fang; Hui Huang; Yongping Gan; Chu Liang; Jun Zhang; Xuesong Liu, New Journal of Chemistry, 2018

MnOx/TiO2 (MnTi) and Nd-modified MnOx/TiO2 (MnNdTi) were prepared via a coprecipitation method. The used samples were obtained by exposing the fresh catalysts to 50 ppm SO2 stream at 210 oC for 3 h and 6 h, respectively. Comparative investigations were performed on the fresh and used catalysts to ...


Biodegrabability of several antipsychotic drugs: manual and automatic assessment

03.07.2018 | Sarah Pereira; Susana Costa; Edite Cunha; Marieta L.C. Passos; Andre RTS Araujo; M. Lúcia M.F. S. Saraiva, New Journal of Chemistry, 2018

The present work aims to assess the 5-days biochemical oxygen demand (BOD5) levels of several typical and atypical antipsychotic (AP) drugs to evaluate the biodegradability degree of them. Since the consumption of APs have seen a huge increase nowadays, the BOD5 could be a good parameter to ...


A novel 3-hydroxychromone fluorescence probe for hydrogen sulfide based on an excited-state intramolecular proton transfer mechanism

03.07.2018 | Jingjing Liu; Xiangzhu Chen; Yuanyuan Zhang; Gui Gao; Xueyan Zhang; Shi-Cong Hou; Yuxia Hou, New Journal of Chemistry, 2018

Hydrogen sulfide (H2S) is a signaling gasotransmitter that plays important roles in modulating the functions of different systems. We have designed and synthesized a 3-hydroxychromone-based fluorescence probe A for H2S detection. Probe A is based on a H2S-induced thiolysis reaction as well as an ...


Nitrogen enriched polytriazine as metal-free heterogeneous catalyst for the Knoevenagel reaction in mild condition

03.07.2018 | Monika Chaudhary; Paritosh Mohanty, New Journal of Chemistry, 2018

Nitrogen enriched (52 wt %) nanoporous polytriazine with high specific surface area up to 850 m2 g-1 is synthesized by an ultrafast (30 min reaction time) microwave assisted route using inexpensive precursors cyanuric chloride and melamine at 400 W. The metal-free highly electron rich material is ...
