Though much progress has been made in drug delivery systems, the design of a suitable carrier for hydrophobic drugs is still major challenge researchers.
Adsorption of SO 2 on pure B 12 P and Zn-doped is investigated through density functional theory methods. Zn adsorption BP delivers four optimized geometries: B-Top, P-top, b64, ring-enlarged geometry with energies −57.12 kJ/mol, −14.50 −22.94 −14.83 respectively. The energy pristine boron phosphide −14.92 kJ/mol. Interaction gives different geometries −69.76 −9.82 −104.92 −41.87 Geometric parameters such as dipole moment, Q NBO , frontier molecular orbital analysis, PDOS, global indices...
ABSTRACT In the present study, hexagonal boron nitride (h‐BN) nanosheets were first functionalized with hydroxyl groups (h‐BN‐OH), and then phosphonic acid grafted onto h‐BN surface (BNP) using aminotris(methylenephosphonic acid) (ATMP) through a condensation reaction. The BNP was incorporated into polyvinyl chloride (PVC) matrix to prepare PVC/BNP composites. Thermogravimetric analysis showed an increase in thermal stability, BNP/PVC composites exhibiting greater resistance degradation at...
We present a physics-informed deep learning framework to address common limitations in Confocal Laser Scanning Microscopy (CLSM), such as diffraction limited resolution, noise, and undersampling due low laser power conditions. The optical system's point spread function (PSF) CLSM image degradation mechanisms namely photon shot dark current motion blur, speckle were modeled directly included into model architecture. reconstructs high fidelity images from heavily noisy inputs by using...
ABSTRACT In this study, a porous three‐dimensional polymeric network of poly(3‐sulfopropyl methacrylate) [p(SPMA)] is prepared and embedded with silver nanoparticles (AgNPs) to design nanocomposite catalyst. The analytical techniques including X‐ray diffraction (XRD), Fourier‐transform infrared spectroscopy (FTIR), scanning electron microscopy coupled energy dispersive analysis (SEM–EDX), rheology, UV–visible are used investigate the composition morphology fabricated p(SPMA) hydrogel...
ABSTRACT In the present study, multi‐walled carbon nanotubes (MWCNTs) were sulfonated by 1,3‐propane sultone and distillation–precipitation polymerization, respectively, then incorporated into chitosan (CS) to prepare CS/MWCNTs composite membranes for fuel cell applications. show better thermal mechanical stability than pure CS membrane due strong electrostatic interaction between SO 3 H groups of MWCNTs NH 2 CS, which can restrict mobility chain. The provide efficient proton hopping sites...
Tumor microenvironment-responsive nano drug delivery vehicles are gaining mounting attention in the field of biomedical sciences. The hypoxic response tumorous cells due to very low partial pressure oxygen (some time less than 2.5 mm Hg) tumor tissues makes hypoxia-responsive system as more appealing cancer chemotherapy. Based on these considerations, we synthesized polymeric materials methoxy poly (ethylene glycol)-block-poly (glutamic acid)-graft-6-(2-nitroimidazole) hexyl amine...
Cisplatin (cis-diaminodichloroplatinum, CDDP) loaded methoxy poly (ethylene glycol)-block-poly (glutamic acid-co-phenyl alanine) [mPEG-b-P (Glu10-co-Phe10) (PGlu10) and mPEG-b-P (Glu20-co-Phe10) (PGlu20)] nanoparticles with two different formulations (CDDP/PGlu10 CDDP/PGlu20) are successfully developed in uniformly sizes. In 190 h, the CDDP/PGlu10 shows 30% release at physiological pH 39% lysosomal pH. Similarly, CDDP/PGlu20 60% 90% The sustained controlled of both evidences vitro longevity...
Nanoparticles are nanosized clusters with dimensions less than 100nm.Nanoparticles fabricated by physical, chemical, and biological methods.Physical chemical methods energy intensive involve hazards of contaminations.Biological synthesis nanoparticles is environment friendly, toxic cost effective process.Plants, microorganisms, biomolecules commonly exploited species for merging in this method.In present work we synthesize Chromium oxide method using fungal extract Aspargillus Niger.The...

We report on the influence of various plasma species growth and structural properties indium nitride in plasma-assisted metalorganic chemical vapor deposition. Atomic emission spectroscopy was used to quantify molecular, neutral, ionized nitrogen concentrations above surface. Reflectance Raman X-ray diffraction techniques were characterize grown InN films. It has been found that rather than molecular or neutral is positively correlated with rate. conclude formation present case due...
