The subject of this research work was to analyze the structural and morphological changes TiO2 as a result incorporation CNTs interpret underlying principles for observed interactions. Hybrid TiO2/CNTs nanostructures were prepared by simplified sol-gel method followed monitoring thermally-induced alterations occurring up 400 ºC. effects different type (activated MWCNTs SWCNTs) well variation co...

The pressure dependence of the glass-transition temperature, Tg(P), of the ionic glass-former 2Ca(NO3)2 x 3KNO3, CKN, has been obtained by molecular dynamics (MD) simulations The liquid-glass difference of thermal expansivity, deltaalpha, heat capacity, deltaCp, and isothermal compressibility, deltak, have been calculated as a function of pressure. It has been found that the Ehrenfest relation ...

Sarcolemmal ATP-sensitive potassium (K(ATP)) channels are activated after pathological depletion of intracellular ATP, unlike their pancreatic beta-cell counterparts, which dynamically regulate membrane excitability in response to changes in blood glucose. We recently engineered a series of transgenic (TG) mice overexpressing an ATP-insensitive inward rectifying K(+) channel protein (Kir)6.2 mu...

The mechanism of self-assembly induced by H2O molecules is studied for layered saponite nanoparticles and zeolite with the cage structure by means of positronium (Ps) annihilation spectroscopy together with thermogravimetry and differential thermal analysis (TG-DTA). Prior to hydration the saponite exhibits two kinds of open spaces with their sizes of ∼3 Å and ∼9 Å, whereas open spaces with the...

Bu çalışmada üç farklı kömürün hava atmosferinde yanma prosesleri termal analiz (TG-DTG/DSC) cihazı ile incelendi. Termogravimetrik deneyleri için 25°C’den 1000°C’ye kadar 10°C/dak ısıtma hızında çalışıldı. TG-DTG/DSC verilerinden faydalanarak örneklerin hem ana bölgesi gerekli olan aktivasyon enerjileri hesaplandı, de kendiliğinden ısınma sıcaklıkları belirlendi. Yanma kinetiği modele bağlı (m...

In this study, the CO2 sorption mechanisms and regeneration properties of alumina-based sorbent using K2CO3 loading under high-pressure moderate temperature conditions were examined. To investigate mechanism sorption, a zirconium-based was compared with an sorbent. The capture capacities PAI10, 20, 30, 40 32.3, 63.0, 95.4, 124.5 mg CO2/g sorbent, respectively. we performed XRD, TG/DTG, FTIR ana...

In this study, structural, thermal, and hydrogen (H2) adsorption properties of natural analcime-rich zeolite tuff (A) from Trakya (Turkey) that acid-treated forms investigated. Analcime mineral was treated with 0.1, 0.5, 1, 2, 3 M HCl solutions at 80 °C for 5 h. Differences in structural thermal behaviors the analcime samples before after acid- treatment were examined by X-ray fluorescence spec...

In this research paper in air synthesis of Psyllium and zirconium(IV)tungstoiodophosphate based organo-inorganic hybrid ion exchanger has been reported. Synthesised hybrid ion exchanger has been characterized by FT-IR, SEM, EDS and TGA/DTA/DTG and chemical composition. Ion exchange capacity and thermal studies of the synthesised ion exchanger were investigated using the potassium chloride solut...

This study deals with the physico-chemical, mineralogical and geotechnical characterization of alluvial clays from Batchenga in Cameroon a view to their use as building materials for housing. The clay (Arg.All) was collected locality at village Natchigal (4˚20'40''N 11˚37'40''E 378 m altitude) fired between 900˚C 1100˚C. Characterization performed by XRD, XRF, DTA/DTG, firing tests. DTA/DTG inf...
