Antioxidant and anticholinesterase constituents of Salvia poculata
(Scientific Technical Research Council Turkey-Tubitak, 2009)Two triterpenoids, namely 2 alpha,3 alpha-dihydroxy-24-nor-4(23), 12-oleanadien-28-oic acid (1) and ursolic acid (2); 4. avonoids, namely 5-hydroxy-7,4'-dimethoxyflavone (3), cirsimaritin (4), eupatilin (5), and salvigenin ... -
A biochar-modified carbon paste electrode
(Scientific Technical Research Council Turkey-Tubitak, 2017)The present work examined the use of biochar derived from tea waste as a novel electrode material. For the fabrication of the biochar electrode, suitable amounts of biochar and graphite were mixed with mineral oil for the ... -
Examination of the Electroanalytic Performance of Carbon Nanotube (CNT) Modified Carbon Paste Electrodes as Xanthine Biosensor Transducers
(Scientific Technical Research Council Turkey-Tubitak, 2008)The effect of multi-walled carbon nanotube (MWCNT) and single-wall carbon nanotube (SWCNT) on carbon paste electrode (CPE) electrochemical response was examined by introducing various portions of CNT into the CPE. The ... -
Integral and homothetic indecomposability with applications to irreducibility of polynomials
(Scientific Technical Research Council Turkey-Tubitak, 2009)Being motivated by some methods for construction of homothetically indecomposable polytopes; we obtain new methods for construction of families of integrally indecomposable polytopes. As a result, we find new infinite ... -
Origins of Reverse Bias Currents in a Typical BPW34 Photodiode
(Scientific Technical Research Council Turkey-Tubitak, 2005)Measurements of the dark reverse current in a typical BPW34 silicon photodiode have been made in the temperature range 100-300 K at various reverse bias voltages ranging from 0 to 60 V. Various transport models have been ... -
Preparation, characterization, and adsorption studies of coreAshell SiO2-CeO2 nanoparticles: a new candidate to remove Hg(II) from aqueous solutions
(Scientific Technical Research Council Turkey-Tubitak, 2016)SiO2 supported core@shell nanoparticles (CSNs) have recently attracted great attention due to their unique, tunable, optical, photocatalytic, and higher adsorption properties. In this study, SiO2@CeO2 CSNs were synthesized ... -
A road map to assess critical materials content in boron industrial wastes using sustainable micro-X-ray fluorescence and total reflection X-ray fluorescence instrumentation
(Scientific Technical Research Council Turkey-Tubitak, 2020)Turkey is the leading country in the world in terms of boron production and sale. Increasing boron production goes along with an increasing generation of boron wastes. The pollution of the soil and the air around the waste ... -
Studingon metabolic and antimicrobial activities of some L-plantarum strains isolated from sausages
(Scientific Technical Research Council Turkey-Tubitak, 1999)In this research, a total of 97 Lactobacillus were isolated from 10 different sausage and sosis samples obtained from different markets. Identification results showed that 39 (41.1%) isolates belong to the species L. ... -
Synthesis of new azo dyes and copper(II) complexes derived from barbituric acid and 4-aminobenzoylhydrazone
(Scientific Technical Research Council Turkey-Tubitak, 2008)Four new azo dyes, L-1, L-2, L-3, and L-4, were prepared by linking benzaldehyde p-aminobenzoylhydrazone (3) and p-hydroxybenzaldehyede p-aminobenzoylhydrazone (4) to barbiturie acid and 1,3-dimethylbarbituric acid through ... -
Tunneling-Enhanced Recombination in Polycrystalline CdS/CdTe Solar Cells
(Scientific Technical Research Council Turkey-Tubitak, 2006)The dominant dark current transport mechanism in as-grown and CdCl2 processed CdS/CdTe heterojunction solar cells for temperatures below 300 K was investigated. The current-voltage properties of these solar cells is explained ...
