Physico-chemical analysis

This paper studied the synthesis of calcium oxide (CaO) from snail shells by calcination, crushing, and grinding. Then, the sample was analyzed by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), specific surface area (BET), and particle size.

Lentic systems are a diverse set of inland freshwater habitats (Lakes and ponds) exist across the globe and provide essential resources and habitats for both terrestrial and aquatic organisms. The current work was intended to evaluate the quality of the selected ponds (Pond 1, 2 and 3) in and around Vellore district, TamilNadu. The water samples were collected to determine the physical and chemical parameters during every month in the year 2019. Water parameters such as temperature, pH, dissolved oxygen, Alkalinity, electrical conductivity, Chloride, Sulphate, Nitrate, Ca, Cl was studied.

Ammonia functionalized UiO66 (UiO66–NH2) in the form of thin film was synthesized by a solvothermal method combined with a dip–coating technique and determined with physicochemical characteristics by X–ray diffraction (XRD), scanning electron microscopy (SEM), nitrogen physisorption measurements (BET), infrared spectroscopy (IR), thermogravimetric analysis (TGA), and ultraviolet–visible diffuse reflectance spectroscopy (UV–Vis DRS).

Bothrops snake venoms are known to induce local tissue damage suchas hemorrhage andmyonecrosis. Theopossum Didelphis marsupialisis resistant to these snake venoms and has natural venom inhibitors in its plasma. The aim of this work was to clone and study the chemical, physicochemical andbiological properties ofDM64, an antimyotoxic protein from opossum serum. DM64 is an acidic protein showing 15% glycosylation andwith amolecular mass of 63 659 Da when analysed by MALDI-TOF MS.

Why do proteins adopt the conformations that they do, and what determines their stabilities? While we have come to some understandingof the forces that underlie protein architecture, a precise, predictive, physicochemical explanation is still elusive. Two obstacles to addressing these questions are the unfathomable vastness of protein sequence space, and the difficulty in makingdirect phy-sical measurements on large numbers of protein variants. Here, we review combinatorial methods that have been applied to problems in protein biophysics over the last 15 years.
