Uricase biofunctionalized plasmonic sensor for uric acid detection with APTES-modified gold nanotopping.

Current uric acid detection methodologies lack the requisite sensitivity and selectivity for point-of-care applications. Plasmonic sensors, while promising, demand refinement for improved performance. This work introduces a biofunctionalized sensor predicated on surface plasmon resonance to quantify uric acid within physiologically relevant concentration ranges.

Assessment of Silicone Rubber/Lead Oxide Composites Enriched with BiO, WO, BaO, and SnO Nanoparticles for Radiation Shielding Applications.

This study aimed to prepare silicone rubber composites with heavy metal oxide nanoparticles for gamma ray shielding applications. Different heavy metal oxide nanoparticles were incorporated into the silicone rubber matrix, and the prepared composites were characterized for their thermal, mechanical, and radiation shielding properties. The density of the prepared SR samples ranged from 1.

Mechanical, Morphological, Thermal and the Attenuation Properties of Heavy Mortars Doped with Nanoparticles for Gamma-Ray Shielding Applications.

This study aimed to develop a mortar composite with improved gamma ray shielding properties using WO and BiO nanoparticles, as well as granite residue as a partial replacement of sand. The physical properties and effects of sand substitution and nanoparticle addition on the mortar composite were analyzed. TEM analysis confirmed the size of BiO and WO NPs to be 40 ± 5 nm and 35 ± 2 nm, respectively.

Knowledge and Practice of Primary Health Care Providers in the Management of Asymptomatic Hyperuricemia and Gout in the Qassim Region of Saudi Arabia.

Introduction & Aim The most prevalent type of inflammatory arthritis is gout. It develops because of hyperuricemia, which makes monosodium urate (MSU) crystals accumulate in the joints. However, hyperuricemia does not always cause gout.

Optimum resource allocation in optical wireless systems with energy-efficient fog and cloud architectures.

Optical wireless communication (OWC) is a promising technology that can provide high data rates while supporting multiple users. The optical wireless (OW) physical layer has been researched extensively, however, less work was devoted to multiple access and how the OW front end is connected to the network. In this paper, an OWC system which employs a wavelength division multiple access (WDMA) scheme is studied, for the purpose of supporting multiple users.
