Synthesis of Gold Nanoparticles Using Cucurbitacin E-Glycoside and Methyl Gallate Isolated from Citrullus colocynthis L. Fruit and Evaluation of their Antibacterial and Antibiofilm Activities.

Introduction: Metal nanoparticles have received much attention due to their unique physical dynamics, chemical reactivity, and promising biological applications. Green synthesis using natural compounds is an alternative to traditional chemical methods for the synthesis of nanoparticles.

Materials And Methods: Herein, two secondary metabolites were isolated from different fractions of methanolic extract of Citrullus colocynthis (bitter apple) Schard.

Machine learning based aerosol and ocean color joint retrieval algorithm for multiangle polarimeters over coastal waters.

NASA's Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission, recently launched in February 2024, carries two multiangle polarimeters (MAPs): the UMBC Hyper-Angular Rainbow Polarimeter (HARP2) and SRON Spectropolarimeter for Planetary Exploration One (SPEXone). Measurements from these MAPs will greatly advance ocean ecosystem and aerosol studies as their measurements contain rich information on the microphysical properties of aerosols and hydrosols. The Multi-Angular Polarimetric Ocean coLor (MAPOL) joint retrieval algorithm has been developed to retrieve aerosol and ocean color information, which uses a vector radiative transfer (RT) model as the forward model.

Realizing the Potential of Commercial E-Textiles for Wearable Glucose Biosensing Application.

Advancements in wearable technology have enabled noninvasive health monitoring using biosensors. This research focuses on developing a textile-based sweat glucose sensor using commercially available conductive textiles, evading the complexity of traditional fabrication methods. A comparative analysis of three low-cost conductive textiles, Adafruit 1364, 1167, and 4762, has been conducted for electrochemical glucose detection with glucose-specific enzymes such as glucose oxidase (GOx) and glucose dehydrogenase (GDH).
