This study investigated on the co-pyrolysis of microalgae Chlorella vulgaris and high-density polyethylene (HDPE) waste mixtures which was performed with three types catalysts, namely limestone (LS), HZSM-5 zeolite, novel bi-functional LS/HZSM-5/LS. Kissinger-Kai (K-K) model-free method coupled Particle Swarm Optimization (PSO) model-fitting using thermogravimetric experimental data. A global s...

Sodium alanate (NaAlH4) is a prospective H2 storage material for stationary and mobile applications, as NaAlH4 contains 7.4 wt% of H2, it possible to do multiple release accumulation cycles. Nanoconfinement potential solution enhance the properties NaAlH4. To optimize supporting synthesis method used nanoconfinement NaAlH4, better understanding influence on processes necessary. Thus, from bulk,...

The pyrolysis performances and reaction kinetics of pine needles (PN) were investigated by integrating thermogravimetric analysis, Fourier transform infrared spectroscopy, pyrolysis-gas chromatography/mass spectrometry. average activation energy PN was estimated to be 183.2 kJ/mol Kissinger Akahira Sunose (KAS) 183.8 Flynn Wall Ozawa (FWO), respectively at heating rates 10, 20, 40 °C/min. found...

A 3D elastoplastic phase-field model is used to study the effect of isochronal heating on martensitic transformation in stainless steel quenched cryogenic temperature. The results show that slower heating, larger martensite volume fraction developed heating. simulated microstructures driven by autocatalysis during early stages and coarsening existing units later transformation. internal stresse...

BACKGROUND The thermal decomposition of cephalexine, cefadroxil and cefoperazone under non-isothermal conditions using the TG, respectively DSC methods, was studied. In case of TG, a hyphenated technique, including EGA, was used. RESULTS The kinetic analysis was performed using the TG and DSC data in air for the first step of cephalosporin's decomposition at four heating rates. The both TG an...

as narrative discourses and discursive thematic frame- works on social issues in media can provide us with an insight into how different understandings and perspectives serve to construct dif- ferent presentations of social actors, social events as well as social re- lations and conflicts, it seems necessary to take them into more seri- ous considerations. to this end, the present study was an ...

This study aims to investigate the thermal properties of phase transformation that may occur with effect temperature in Cu-14.70wt.%Al-4.72wt.%Ni shape memory alloy. The sample was annealed at 1203 K for 30 min an argon atmosphere and then cooled rapidly salt-ice water. By using Differential Scanning Calorimetry (DSC), martensitic parameters were found. activation energy required these transfor...

Abstract Non-isothermal reaction mechanism and kinetic analysis for the synthesis of monoclinic lithium zirconate (m-Li 2 ZrO 3 ) were investigated by processing TG-DTA, along with XRD, DLS, HRTEM. For this purpose, solid-state Li CO was carried out TG-DTA at different heating rates (10, 20, 30 °C/min) from room temperature to 1100 °C. The thermal data used calculate parameters two types isocon...

In here, the nonisothermal decomposition kinetics of co-polymers based phenothiazine was present-ed. For this, firstly, 3, 7-di-2-thienyl-10H-phenothiazine (TF) prepared via an optimized Suzu-ki–Miyaura cross-coupling reaction. After monomer characterization, copolymerization re-actions with EDOT and thiophene were performed by electrochemical technique. The molecular masses found gel permeatio...
