Enhanced electrocatalytic efficiency of C/MWNTs for methanol oxidation using Ni deposited on MWNTs
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2015)
The power density of direct methanol fuel cells (DMFCs) can be changed by using different anode materials. Especially porous materials are preferred for the anode. In the present study, multiwall carbon nanotubes were first ...
Synthesis of metal-free and metallophthalocyanines containing 18-and 21-membered macrocycles with mixed donor atoms and their metal-ion binding properties
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2015)
This paper describes the synthesis of a series of metal-free phthalocyanines and metallophthalocyanines peripherally substituted by macrocycles of different ring sizes with the same donor atom sets. The effects of varying ...
Optimization of geometrically nonlinear lattice girders. Part I: considering member strengths
(VILNIUS GEDIMINAS TECH UNIV., 2015)
In this study, the entire weight, joint displacements and load-carrying capacity of tubular lattice girders are simultaneously optimized by a multi-objective optimization algorithm, named Non-dominated Sorting Genetic ...
Synthesis, characterization, and metal extraction studies of a new macrobicyclic ligand
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2015)
This article describes the synthesis, characterization, and metal ion binding properties of a new macrobicyclic ligand. Solvent extraction experiments were performed in order to determine the extraction behavior of new ...
A study on nuclear properties of Zr, Nb, and Ta nuclei used as structural material in fusion reactor
(EDP SCIENCES., 2015)
Fusion has a practically limitless fuel supply and is attractive as an energy source. The main goal of fusion research is to construct and operate an energy generating system. Fusion researches also contains fusion structural ...
Problems in detection and measurement in nuclear medicine
(EDP SCIENCES., 2015)
Nuclear Medicine studies are performed with a variety of types of radiation measurement instruments, depending on the kind of radiation source that is being measured and the type of information sought. For example, some ...
Photoredox cross-coupling: Ir/NidDual catalysis for the synthesis of Benzylic Ethers
(AMER CHEMICAL SOC., 2015)
Single-electron transmetalation has emerged as an enabling paradigm for the cross-coupling of C-sp(3) hybridized organotrifluoroborates. Cross-coupling of alpha-alkoxymethyl-trifluoroborates with aryl and heteroaryl bromides ...
Single-electron transmetalation: An enabling technology for secondary alkylboron cross-coupling
(AMER CHEMICAL SOC, 2015)
Single-electron-mediated alkyl transfer affords a novel mechanism for transmetalation, enabling cross-coupling under mild conditions. Here, general conditions are reported for cross-coupling of secondary alkyltrifluoroborates ...
Comparison of Volatile Compounds of Fresh Boletus edulis and B. pinophilus in Marmara Region of Turkey
(UNIV AGR SCI & VETERINARY MED CLUJ-NAPOCA, 2015)
Boletus edulis and B. pinophrlus are commonly consumed edible species of Boletus spp. in Turkey, which are also exported to some European countries. In this study, twenty-three volatile compounds were determined with ...
Semi-Empirical Formula with New Coefficients of the (alpha,n) Reaction Cross-Section
(POLISH ACAD SCIENCES INST PHYSICS, 2015)
A new modified semi-empirical formula including non-elastic scattering and Coulomb effects for the (alpha,n) reaction cross-section was obtained. The available experimental data were used to get the (alpha,n) reaction ...
