Characterization and distribution of mineral phases in an Amazonian humiluvic Spodosol profile by XRPD, HR-TEM, SAED and SEM–EDX
(2021-06-01)
The Amazonian biome has a fundamental role in the global climate change scenario and the understanding the physicochemical aspect in Amazonian soils is of great importance. The nine horizons constituting a typical Amazonian ...
Chemometrics-assisted solid-state characterization of pharmaceutically relevant materials. Polymorphic substances
(Elsevier Science, 2018-01)
Current regulations command to properly characterize pharmaceutically relevant solid systems. Chemometrics comprise a range of valuable tools, suitable to process large amounts of data and extract valuable information ...
Characterization of pharmaceutically relevant materials at the solid state employing chemometrics methods
(Elsevier Science, 2018-01)
The understanding of materials and processes is a requirement when it comes to build quality into pharmaceutical products. This can be achieved through the development of rapid, efficient and versatile analytical methods ...
Influence of ethylcellulose-Medium chain triglycerides blend on the flow behavior and β-V polymorph retention of dark chocolate
(Elsevier, 2016-10)
Chocolate manufacturing involves steps during which molten mass is prepared to be converted in a solid with selected textural and melting properties which are vital for the consumer's acceptance. A central element in this ...
Role of aluminum chloride on the reversible hydrogen storage properties of the Li-N-H system
(Pergamon-Elsevier Science Ltd, 2015-10)
In order to understand the role of AlCl3 addition on the Li-N-H system, we have systematically investigated the hydrogen sorption kinetics and the reactions between LiNH2-LiH and AlCl3 additive with a multitechnique approach ...
Thermal studies, degradation kinetic, equilibrium solubility, DFT, MIR, and XRPD analyses of a new cocrystal of gemfibrozil and isonicotinamide
(2019-06-15)
A synthesis of a novel pharmaceutical cocrystal of the gemfibrozil (GEM) with the isonicotinamide (INCT) as coformer was carried out using the mechanochemical method of solvent drop grinding. The cocrystal formation was ...
Sintering and crystallite growth of nanocrystalline copper doped tin oxide
(Amer Chemical Soc, 1999-04-08)
The effect of Cu2+ contents and of firing temperature on sintering and crystallite growth of nanocrystalline SnO2 xerogels was analyzed by thermoanalysis (mass loss (TG), linear shrinkage, and differential thermal analysis ...

This article describes the mechanochemical synthesis (liquid-assisted grinding (LAG) and neat grinding (NG)), characterization and thermoanalytical study of new cocrystals of ciprofloxacin (CIP) with picolinic acid (PCA) ...
Characterization of hydrochlorothiazide in solid formulations
(2015-03-03)
Hydrochlorothiazide (HCTZ) is a diuretic used for the treatment of blood pressure (hypertension). HCTZ has two anhydrous polymorphs denoted as Forms I and II. Aiming at solid-state characterization, X-ray powder diffraction ...
Preparation and characterization of a new solid form of praziquantel, an essential anthelmintic drug: Praziquantel racemic monohydrate
(Elsevier Science, 2020-04)
Praziquantel (PZQ) is a highly effective low-cost anthelmintic agent used as the first-choice treatment against schistosomiasis. The low solubility of the active is a major drawback for pharmaceutical formulation. A valid ...
