Abstract Background Parkinson’s disease is generally asymptomatic at earlier stages. At an early stage, there extensive progression in the neuropathological hallmarks, although, this diagnosis not possible with currently available diagnostic methods. Therefore, pressing need for susceptibility risk biomarkers that can aid better and therapeutics as well objectively serve to measure endpoint of progression. The role small extracellular vesicles (sEV) neurodegenerative diseases could be potent...
Abstract Terephthalic acid (TPA) has been extracted from waste polyethylene terephthalate (PET) bottles, which used to prepare the Sn‐based catalyst precursors. The precursors were calcined obtain SnO 2 catalysts. catalysts have synthesized using microwave synthesizer [SnO (M)] and oil bath reflux setup (O)]. For comparison, a prepared without TPA PET waste, (C)]. characterized by various techniques such as X‐ray diffraction (XRD), N adsorption–desorption analysis, Fourier transform‐infrared...
We report high‐power InGaN back‐barrier AlGaN/GaN high electron mobility transistors with the gate placed closer to source an Au‐filled groove in SiC substrate near drain end. An is known reduce short‐channel effects at drain‐to‐source ( V DS ) voltage. However, improvement realized cost of reduced two‐dimensional gas density n s and saturation I DS,SAT current. Here, we demonstrate that both are recovered when appropriately delineated source. The junction temperature increases higher DS,...
Determining junction temperature and two-dimensional profile is critical for high-power GaN-based high electron mobility transistors to optimize performance, improve device reliability, better thermal management. Here, we have demonstrated that resistance detectors of the same material as gate contact delineated between gate-to-source gate-to-drain regions can accurately along channel. The asymmetric skewed toward drain side, degree asymmetry used determine effective length experimentally. A...

In this manuscript, ZnO nanoparticles (NPs) doped with 8 and 10 wt. % Sm2O3 were prepared using Co-precipitation method annealed at 400 °C. The samples characterized X-ray diffraction (XRD), Transmission electron microscopy (TEM), UV-Vis-NIR spectroscopy soft absorption (SXAS) techniques. surface morphology particle size distribution studied TEM nano-crystalline having of the order 21-23 nm spherical shape. results UV-Vis spectra indicate that band gap decreases for concentration further it...
Isothermal titration microcalorimetry experiments are performed to measure the heat of adsorption poly(ethylene glycol) (PEG) on nonporous silica nanoparticles. A calorimetric technique is also developed for determination isotherm PEG–silica system. model based continuum form self-consistent field theory used estimating polymer–surface interaction parameter, χ*, from polymer. The effect temperature and molecular weight PEG χ* has been determined. It shown that adsorbed amount silica,...
The data presented in this article support the research entitled "Development of a rationale for decoupling osmotic coefficient electrolytes into electrostatic and nonelectrostatic contributions" (Sahu Juvekar, 2018) [1]. In article, we have plots coefficients against molality more than hundred aqueous single at 25 °C. linear regions these are marked to show that they present all extend over wide range concentrations. Slopes used estimate primary molar hydration volume as well number...
Abstract This work demonstrates the improvement in DC and RF characteristics a reduction gate leakage current for thermally grown Nb 2 O 5 as dielectric AlGaN/GaN metal–oxide–semiconductor high electron-mobility transistors (MOS-HEMTs). The MOS-HEMTs with an amorphous 10 nm thick show reduced of −9 A mm −1 . thin film creates tensile strain AlGaN layer, enhancing density two-dimension electron gas (2-DEG). performance device also improves terms saturation drain current, peak...
Silicon nitride (SiN x ) is used for device passivation and capacitance dielectric in GaN monolithic microwave integrated circuits. However, this a conflicting requirement as requires SiN to cause tensile strain, primarily demands high breakdown voltage large constant , leading damaged AlGaN surface during deposition. Two independent depositions under two different conditions (silicon‐ nitrogen‐rich) are usually carried out meet both requirements. Herein, solution unified deposition through...

Acne is a chronic inflammatory condition of the pilosebaceous unit caused by androgen-induced changes in keratinization, inflammation, and sebum production. It often affects face, back, chest due to clogged hair follicles from oil, dead skin cells, bacterial colonization, primarily Propionibacterium acnes. Hormonal during adolescence, family history, possibly early P. acnes colonization contribute its development. While dietary factors have been suggested, evidence remains inconclusive. 9.4%...
Prediction of the osmotic coefficient concentrated electrolytes is needed in a wide variety industrial applications. There need to correctly segregate electrostatic contribution from nonelectrostatic contribution. This achieved rational way this work. Using Robinson-Stokes-Glueckauf hydrated ion model predict non-electrostatic coefficient, it shown that hydration number should be independent concentration so observed linear dependence on electrolyte high range could predicted. The several...
This work is the extension of our previous [Fluid Phase Equil. 2018, 460, 57; Data in Brief 19, 485]. In this work, a predictive model has been developed for electrostatic interaction which based on cell model. model, there are three regions around central ion. Owing to presence very high electric field (approximately 1010 V·m–1) ion, water molecules highly oriented toward ion and have dielectric constant less than second region (partially molecules). The third contains with as bulk water....
