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...

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...

The synthesis of sodium 2-chlorobenzylidenepyruvate and its corresponding acid as well as binary, binary together with it’s acid or hydroxo-2-chorobenzylidenepyruvate of aluminium (III), gallium (III) and indium (III), were isolated. Chemical analysis, thermogravimetry, derivative thermogravimetry (TG/DTG), simultaneous thermogravimetry-differential thermal analysis (TG-DTA) and X-ray powder di...

MgHPO4·3H2O was synthesized via a simple wet reaction and transformed to its final decomposed product, Mg2P2O7 at 873 K. The thermal properties, vibrational modes of block units, solid phases the synthetic compounds have been investigated by TG/DTG/DTA, FTIR, XRD techniques. temperature dependence thermodynamic properties estimated from DSC data occurred in two regions (before after dehydration...

a complex of cu(ii) with 1-(6-hydroxynaphthalen-2-yl) butane-1,3-dione (hnbd) was synthesized and characterized by elemental analysis, ir, uv and dta-tg-dtg techniques.    ir spectra as well as uv-visible absorption measurements indicated that cu(ii) ion was coordinated to the hnbd ligand. the tg-dta-dtg curves showed that thermal decomposition of the anhydrous complex was a two-stage process a...

This paper investigated thermal properties of natural thaumasite, such as phase composition and reaction mechanism decomposition using simultaneous TG/DTG-DSC in Ar Air medium up to 1673 K, coupled with masspectrometer for analysis evolving gases, in-situ powder X-ray diffraction measurements. The transitional solid phases, grown increasing temperature at thaumasite decomposition, are calcium h...

The thermal decomposition processes for metal complexes of nalidixic acid (NAL) viz: Co (NAL) OH , VO(NAL)2(H2O)3 , UO2 (NAL) 2(H2O)2 , Ru(NAL)2Cl(H2O) has been accomplished on the basis of TG, DTG and DTA studies, and the mechanism conforms to the stoichiometry of the complexes based on elemental analysis.

Excess oxygen radical formation is suggested to be involved in the etiology of diabetic embryopathy. We aimed to investigate the effects of altered maternal antioxidative status in conjunction with a varied severity of the maternal diabetic state on embryonic development by using mice with different gene expression of CuZn superoxide dismutase (CuZnSOD). The mice were wild-type (WT), transgenic...
