Development and Performance Evaluation of a Polyethersulfone–Graphene Oxide Ultrafiltration Membrane for Simultaneous Drug Delivery and Virus Removal: An Experimental Investigation
Abstract: The development of multifunctional ultrafiltration membranes for simultaneous controlled drug delivery and viral removal has gained considerable attention in biomedical engineering, pharmaceutical sciences, and water purification. Polyethersulfone (PES) membranes offer excellent thermal, chemical, and mechanical stability; however, their hydrophobicity can limit permeability, antifouling performance, and biocompatibility. This study proposes the fabrication of PES–graphene oxide (GO) ultrafiltration membranes using the phase inversion technique, with systematic variation of GO concentration to optimize …

Development and Evaluation of a Cost-Effective UV-Protective Cream Containing Para-Aminobenzoic Acid and Aloe Vera for Indian Climatic Conditions.
Abstract: The increasing incidence of ultraviolet (UV) radiation-induced skin disorders has heightened the demand for effective, affordable photoprotective agents, especially in countries with high sun exposure such as India. This study aimed to develop a cost-effective and efficient UV-B protective cream formulation suitable for populations in Indian latitudes. Para-aminobenzoic acid (PABA) was selected as the primary sunscreening agent due to its high UV-B absorption efficiency, low toxicity, and affordability compared with …

Asymmetric Membrane Capsules for Delivery of Poorly Water Soluble Drugs
Abstract: After the successful implementation of asymmetric membrane in osmotic tablet preparation, it also diversified towards capsular system. The asymmetric membrane capsule is a controlled drug-delivery device widely used in controlled osmotic drug delivery. The phase-inversion technique is utilized to nurture such units. It has a relatively thin dense region supported on a thicker porous region, hence called asymmetric. In contrast to gelatin capsules, however, the walls of asymmetric membrane capsules …

Hidden Buck Chopper Circuits Topology in a Switch Controlled Singe Phase Rectifier, Size and Cost Analysis
Abstract: This paper shows hidden buck chopper circuits topology in a single phase switch controlled full wave rectifier. Justification of this realization yields the opportunity to use the single circuit structure for both AC to DC and DC to DC conversion processes. Generally, two diodes out of four diodes are replaced by two switches to offer voltage gain and input power factor regulation in a single phase full wave rectifier. Such …
