Issues related to the thermal stability of front contacts, based on Cr-Au and Cr-Au-Ag-Au, GaSb-based photovoltaic cells have been considered at operational (the cell temperature is 50 o C) standard conditions as well forced degradation (at 125 200 C). It shown that converter with silver-containing contact preferable in terms resistivity, external quantum yield, FF, V oc , therefore, efficiency...

Forced aeration is one of the promising ways to accelerate landfill reclamation, and understanding relation between rates waste properties prerequisite implementing forced under target energy saving carbon reduction. In this work, reclamation processes with were simulated using aged refuses (ARs) 1, 4, 7, 10, 13 disposal years, potential field application was also investigated based on a projec...

In the research, spherical α-Fe2O3 NanoParticles (NPs) were synthesized through Forced Hydrolysis and Reflux Condensation (FHRC) process and were supported on the surface of silica sand by Solid-State Dispersion (SSD) method. Characterization of silica and α-Fe2O3/SiO2 catalyst was done using Fourier-Transform InfraRed (FT-IR) spectrosc...

PURPOSE A simple stability-indicating RP-HPLC assay method was developed and validated for quantitative determination of Chloramphenicol, Dexamethasone Sodium Phosphate and Tetrahydrozoline Hydrochloride in ophthalmic solution in the presence of 2-amino-1-(4-nitrophenyl)propane-1,3-diol, a degradation product of Chloramphenicol, and Dexamethasone, a degradation product of Dexamethasone Sodium P...

Elucidation and quantitative determination of some of commonly used penicillins (ampicillin, penicillin G and carbenicillin) in the presence of their main degradation product (penicilloic acid) were developed. Forced acidic and basic degradation processes were applied at different time intervals. The formed degradation products were elucidated and quantified using surface enhanced Raman spectro...

All activities should aim to eliminate genotoxic impurities and/or protect the API against degradation. There is a necessity to monitor impurities from all classification groups, hence ivabradine forced degradation studies were performed. Ivabradine was proved to be quite durable active substance, but still new and with insufficient stability data. Increased temperature, acid, base, oxidation r...

A simple, selective, precise and accurate stability-indicating high-performance liquid chromatographic method for analysis of Erdosteine and its degradation products in tablet dosage form was developed and validated. The stability indicating ability of the method was determined by performing forced degradation studies which indicated susceptibility of the drug under acidic and neutral hydrolyti...

A sensitive, selective and stability indicating reverse phase method has been developed for the quantitative determination of potential impurities of Desvenlafaxine succinate monohydrate active pharmaceutical ingredient. Efficient chromatographic separation was achived on C8 stationary phase. Forced degradation study confirmed that the newly developed method was specific and selective to the de...
