DFT study for radical capture by mitochondria

oxidotoxin protective ionic and non-ionic amphiphilic

α-phenyl-N-t-butyl nitrone derivatives

Sutapa Mandal & Nivedita Acharjee*

DFT analysis for radical capture by biologically active

amphiphilic α-phenyl-N-t-butyl nitrone derivatives is reported.

Analysis of global and local reactivity descriptors is presented

from both natural and electrostatic based charges. Transition states

for radical attacks have been located and the activation barriers for

radical capture are calculated. The cis attack is energetically

favored in each case. Hyperfine splitting constants have been

computed and compared with the reported experimental findings.

Thermophysical, excess and transport properties of

organic solvents with imidazolium based ionic liquids

Akanksha Saini, Aditya Harshvardhan & Ranjan Dey*

Ultrasonic velocity and refractive index are evaluated for eight

binary mixtures comprising imidazolium based ionic

liquids ([BMIM][PF6], [HMIM][PF6], [OMIM][PF6] and

[MMIM][CH3SO4]) with organic solvents of varying nature, viz.,

2-propanol, 2-butanone and ethylacetate, at 293.15, 298.15 and

303.15 K.

Nickel(II) complex based on bis-(1-(pyridin-2-yl-methyl)-

benzimidazol-2-yl-methyl) ether and its utilization in the

oxidation of 2-amino-4-tert-butylphenol

Raghvi Khattar, Anjana Yadav, Kuldeep Mahiya &

Pavan Mathur*

Ni(II) complex of a bis-benzimidazole ligand crystallizes in the

tetragonal system with space group I41/a and appears to be

propeller-shaped when viewed along the c-axis.

Improved photocatalytic performance of (ZnO/TiO2)-β-CD

on decolorization of brilliant green dye under UV light

irradiation

P Velusamy* & G Lakshmi

The (ZnO/TiO2)-β-CD system has higher photocatalytic activity

than (ZnO/TiO2), ZnO and TiO2 due to the synergistic effect of ZnO

and TiO2 as well as the formation of strong inclusion complexes

between β-CD and BG dye molecules.

Synthesis and characterization of gadolinium tungstate

doped zinc oxide photocatalyst

Kuppulingam Thirumalai, Manohar Shanthi &

Meenakshisundaram Swaminathan*

Gd2WO6-ZnO with the morphological structure of nanorods and

microsponge acts as an effective electron scavenger to trap the

conduction band electrons of ZnO.

A comparative study of the photocatalytic

properties of CuS nanotubes and nanoparticles by

hydrothermal method

Xuyan You, Xiaohong Geng, Xiue Liu, Yang Yu &

Zhihong Jing*

Copper sulfide nanotubes and nanoparticles have been

successfully synthesized by a hydrothermal process at 160 °C for

10 h, employing copper chloride and thioacetamide as starting

materials, and polyethylene glycol-400 as surfactant. Both, CuS

nanotubes and nanoparticles, belong to the hexagonal phase CuS.

The CuS nanotubes with smooth inside and coarse outside present

higher photocatalytic performance than the CuS nanoparticles.

Nitrogen doped graphene supported Pt-Pd nanoparticle

modified GC electrode for electrochemical

determination of tramadol and paracetamol

Janakiraman Manokaran, Jonna Narendranath,

Rethinasabapathy Muruganantham &

Natesan Balasubramanian*

The NGp-PDDA supported Pt-Pd nanoparticle modified electrode

detects paracetamol over a concentration range of 5×10-6

to 1×10-4 M, and tramadol from 1.2×10-5 to 2.4×10-4 M. The

limit of detection is found to be 1.8×10-7 and 5.7×10-6 M,

respectively (S/N = 3).
