The introduction of pillared agents or dopants to the graphene used as electroactive material in supercapacitor electrodes can be an efficient way facilitate ion transfer, mitigate re-stacking, and improve electrochemical performance. We evaluated effect different precursors containing nitrogen (N) sulfur (S) atoms dope flake (GF) lattices. performance doped GF was assessed 1 M KOH Na2SO4 elect...

تخریب عمده قسمتهای مسیر داغ توربین های گازی از جمله پرده های توربین و محفظه احتراق در اثر حضور آلاینده های نمکی موجود در سوخت و هوای ورودی یکی از مشکلاتی است که صنعت از دیرباز با آن مواجه بوده است . این فرایند تخریب تحت عنوان پدیده خوردگی داغ، نوعی از اکسیداسیون شتاب یافته است که در درجه حرارتهای بالا و در محیطهای اکسید کننده گازی در روی ماده ای که سطحش با فیلم نازکی از نمک مذاب پوشیده شده است ...

The fundamental behavior of sodium sulfate crystallization and induced decay in concrete and other building materials is still poorly understood, resulting in some misinterpretation and controversy. We experimentally show that under real world conditions, both thenardite (Na2SO4) and mirabilite (Na2SO4 10H2O) precipitate directly from a saturated sodium sulfate solution at room temperature (20°...

Interactions and phase behavior of γ-globulins are of fundamental interest in biophysical and pharmaceutical research, as these are among the most abundant proteins in blood plasma. In this work, we report the characterization of the oligomeric state of bovine γ-globulin, the effective protein-protein interactions, and the colloidal stability in aqueous solution as a function of protein concent...

Salt stress is a common abiotic that negatively affects crop growth and yield. However, there have been significant differences found on the effect degree management mechanism in plants under neutral salt alkaline stress. In this study, two soybean cultivars, Heihe 49 (HH49, saline-alkali tolerant) Henong 95 (HN95, sensitive), were hydroponically cultured treated with solutions of 25, 50, 75 mM...

Salinity is one of the most brutal environmental stresses that hamper crop productivity worldwide Approximately 10% of the total land surface is salt affected and about 10 million hectare of agricultural land is lost annually due to salinization and water logging. This study was conducted to determine the ion exchanges in Halocnemum strobilaceum and Halostachys caspica in saline conditions. The...

This investigation aims to obtain a thermosensitive platform useful for specific nanomedicine applications through the addition of suitable salts. An aqueous mixture consisting copolymer Pluronic F127 and sodium carboxymethyl-cellulose, in ratio 20/4 by weight, presence different concentrations Na2SO4, NaCl, NaSCN, was investigated using visual inversion tube approach estimate phase map, then c...
