Bahra University is a private university located in Waknaghat, Solan district, Himachal Pradesh, India. The university was established in 2011 by the Rayat-Bahra Group (registered as Bahra Educational and Charitable Society) through the Bahra University (Establishment and Regulation) Act, 2010. The Rayat-Bahra Group also established Rayat Bahra University and other education institutes including Rayat Institute of Engineering & Information Technology..
The strength, longevity, and safety of metal buildings exposed to harsh acidic conditions like HCl and H2SO4 are all greatly impacted by corrosion. With potential uses in acid pickling and industrial cleaning procedures, Phanera vahlii extract was examined in this work as a green corrosion inhibitor for mild steel in 0.5 M H2SO4. Gravimetric tests, UV–visible spectroscopy, scanning electron microscopy (SEM), electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP), and quantum chemical computations were used to assess the inhibitory performance. The findings showed that at 4000 mg L⁻1, the greatest inhibitory efficiency was 96.47
Pure and Sm doped Ni-Zn ferrite nanoparticles, Ni0.5Zn0.5Fe2−xSmxO4 were synthesized to study the relationship between defect-induced structural distortion, optical disorder, and photocatalytic kinetics. X-ray diffraction analysis confirmed the formation of a single-phase cubic spinel structure. The crystallite size of pure sample was found to be 26.02 nm. Williamson–Hall analysis indicated a reduction in crystallite size from 53.95 nm to 15.07 nm due to increased lattice strain. Structural stability was confirmed by the distinctive tetrahedral and octahedral vibrations, recorded in FTIR spectra. UV-visible spectroscopy studies confirmed a decrease in optical band gap from 1.89 eV to 1.71 eV along with a decrease in Urbach energy from 0.33 eV to 0.27 eV, which indicates lower band tail disorder and controlled defect distribution. The Sm0.08 composition exhibited higher photocatalytic activity in degradation of the methylene blue dye with up to 98
Captopril (CAP) is an antihypertensive drug commonly prescribed for hypertension and heart failure. In current research, the molecular interactions of CAP were examined in water and normal saline at various concentrations (0.001-0.010) molkg-1 and temperatures (295.15-315.15) K. To address this objective, we measured the densities (rho), ultrasonic velocities (c), specific conductance (kappa), and viscosities (eta) of CAP in water and normal saline solvent systems. The experimentally determined data were used to evaluate various volumetric, acoustic, conductometric, and viscometric parameters. The outcomes obtained from these parameters were estimated in terms of drug-solvent and drug-drug interactions. The findings of physicochemical studies reveal strong binding affinity and structural organization behavior of CAP in water/normal saline, and these findings were supported by UV-visible and FTIR studies. The DFT studies were also carried out to evaluate various quantum parameters and visualize FMOs and ESPS of CAP and NaCl in water. The ADMET profile of CAP and molecular docking with the targeted protein 2YDM were studied to evaluate their pharmacokinetic behavior and binding efficacy. This investigation can help the scientific community to optimize drug design and drug delivery, leading to improved biological efficacy in the pharmaceutical and healthcare sectors.
Background: Chemically synthesized powders, such as magnetic powders, nanopowders, and fluorescent powders, are frequently employed for the purpose of fingermark development at crime scenes. Aim and Objective: Although they offer good quality fingermarks that adhere well to surfaces, their development expenses are excessive, and because they are chemically synthesized, they present a toxicity risk to people’s health. As a result, herbal powders may be used in lieu of these powders, as they are eco-friendly, cost-effective, and nontoxic to human health. Material and Method: In our research study, we employed one such herbal powder, namely wheatgrass powder, to develop fingermarks on a variety of nonporous surfaces, such as wood, glass, plastic, granite, ceramic tile, leather, iron, fiberglass, steel, and aluminum foil. Result and Discussion: The results obtained from these surfaces demonstrate that this technique is an effective means of fingermark development at crime scenes.
