(TAYLOR & FRANCIS LTD, 2014)
Density functional calculations of the structure, vibrational spectra, molecular electrostatic potential and thermodynamic functions have been performed at the B3LYP/6-311 ++ G(d,p) level of theory for the Schiff base ...
DETERMINATION OF FORM DEFECTS DEPENDING ON TOOL DEFLECTION IN BALL END MILLING OF CONVEX AND CONCAVE SURFACES
(GAZI UNIV, FAC ENGINEERING ARCHITECTURE, 2014)
Altering in surface forms cause to varying cutting forces in machining of inclined surfaces by ball end mills. The deflections appeared by cutting forces can result in form defects in workpiece. Finding deflection values ...
Stimuli-responsive diblock copolymer brushes via combination of "click chemistry" and living radical polymerization
(WILEY-BLACKWELL, 2013)
pH- and temperature-responsive poly(N-isopropylacrylamide-block4-vinylbenzoic acid) (poly(NIPAAm-b-VBA)) diblock copolymer brushes on silicon wafers have been successfully prepared by combining click reaction, single-electron ...

A new selenium-based RAFT agent for surface-initiated RAFT polymerization of 4-vinylpyridine
(ELSEVIER SCI LTD, 2013)
A new selenium-based reversible addition-fragmentation chain transfer (RAFT) agent, 4-cyanopentanoic acid diselenobenzoate (RAFT-Se), was synthesized and utilized in the surface-initiated RAFT polymerization of 4-vinylpyridine ...
First principles studies of hydrogen sulfide adsorption and dissociation on NiAl(110)-(2x2)
(NATL INST OPTOELECTRONICS, 2013)
The molecular and dissociative adsorption of H2S molecule on NiAl(110) surface is examined using density functional theory (DFT). We have considered the five possible adsorption sites given in Fig.1. We have found that the ...
