Binding energies of shallow donors in polar ZnO/ZnBeO quantum well
(Elsevier, 2024)
This study examines a single wurtzite ZnO/ZnBeO quantum well structure oriented in the polar c -direction. The focus is on investigating the binding energies associated with an impurity donor atom within this system. To ...
The continuity in q of the Lupaş q-analogues of the Bernstein operators
(Elsevier, 2024)
The Lupas q-analogue Rn,q of the Bernstein operator is the first known q-version of the Bernstein polynomials. It had been proposed by A. Lupas in 1987, but gained the popularity only 20 years later, when q-analogues of ...
Cellulose ester-based aerogel: lightweight and highly water-absorbent
(American Chemical Society, 2023)
Cellulose was extracted from waste generated by pruning tea stem wastes. The interaction between pure cellulose and homophthalic acid produced a light (0.22 g·cm-3) and eco-friendly hybrid aerogel product that is highly ...
Synthesis and spectroscopic studies of homo-binuclear, alkoxo bridged homo- and hetero-tetranuclear metal complexes of a bis-N 2O 4 Schiff base ligand derived from ethanolamine and macroacyclic tetranaphthaldehyde
(Elsevier, 2011)
Three new homo-binuclear Ni(II), Cu(II), Zn(II) complexes (2-4), homo-tetranuclear Cu(II) complex (5), and hetero-tetranuclear Cu(II)-Ni(II) complex (6) of a macroacyclic potentially bis-hexadentate N 2O 4 Schiff base have ...
Preparation and characterization of new window material CdS thin films at low substrate temperature (<300 K) with vacuum deposition
(Elsevier, 2011)
Low-temperature vacuum deposition instead of the commonly used vacuum deposition at high substrate temperatures has been applied to prepare new window material CdS thin films. The structural, optical and electrical properties ...
Experimental and theoretical study on the structure and vibrational spectra of β-2-aminopyridinium dihydrogenphosphate
(Elsevier, 2011)
Experimental and theoretical vibrational spectra of ?-2- aminopyridinium dihydrogenphosphate (?-2APDP) have been investigated. The FT-IR spectrum of ?-2APDP was recorded in the region 4000-400 cm -1. The optimized molecular ...
Structural analysis of naproxen-intercalated bentonite (Unye)
(Elsevier, 2011)
The difference in the basal spacing (8.79Å) and a higher mass loss (6.2%) in the temperature range of 200-750°C of naproxen-bentonite (N-bentonite) comparing to that of Unye bentonite (UB) signified the existence of thermally ...
Effect of CdCl2/annealing on the crystalline transformation of CdTe thin films grown by evaporation at a low substrate temperature
(TÜBİTAK, 2011)
The structural and optical properties of CdTe thin films prepared at a low substrate temperature were investigated before and after the CdCl 2/annealing. The crystal structure of CdTe film was cubic with a strong (111) ...
Silorane-based composite: Depth of cure, surface hardness, degree of conversion, and cervical microleakage in class II cavities
(Wiley, 2011)
Objective: The purpose of this study was to determine the depth of cure, degree of conversion (DC), hardness, and cervical sealing ability of silorane-based composite (Filtek Silorane [FS; 3M, Seefeld, Germany]) and to ...
Determination of the pKa of Some triazole derivatives by the potentiometric method in dioxan-water mixtures
(2011)
Stoichiometric protonation constants of some 3-alkyl(aryl)-4-(substituted benzylamino)-4,5-dihydro-1 H-1,2,4-triazol-5-ones derivatives were determined potentiometrically in 50% (v/v) dioxan-water mixtures at 25°C with an ...
