Polarization-Insensitive, High-Efficiency Metasurface with Wide Reception Angle for Energy Harvesting Applications.

This research presents an innovative polarization-insensitive metasurface (MS) harvester designed for energy harvesting applications at 5 GHz, capable of operating efficiently over wide reception angles. The proposed MS features a novel wheel-shaped resonator array whose symmetrical structure ensures insensitivity to the polarization of incident electromagnetic (EM) waves, enabling efficient energy absorption and minimizing reflections. Unlike conventional designs, the metasurface achieves near-unity harvesting efficiency, exceeds 94% under normal incidence, and maintains superior performance across various incident angles for TE and TM polarizations.

Maillard-derived mung bean protein-peach gum conjugates: A novel emulsifier to improve stability, antioxidants, and physicochemical properties of chia seed oil nanoemulsion.

This research is designed to enhance the physio-chemical properties, constancy, and antioxidant activities of water-in-oil (W/O) emulsions containing chia seed oil (CSO) by utilizing mung bean protein isolate (MBPI)-peach gum (PG) conjugates, which were created through the Maillard reaction (MR), as the emulsifying agents. The emulsions were prepared using MBPI-PG produced through the Maillard reaction (EMRP) at concentrations of 0.5 %, 1 %, and 1.

Microencapsulation using a novel wall material prepared via Maillard reaction-derived mung bean protein-peach gum conjugates to enhance stability and functionality of chia seed oil.

This study investigated the potential of Maillard reaction products (MRPs) derived from mung bean protein isolate (MBPI) and peach gum (PG) conjugates as wall materials for microencapsulating chia seed oil (CSO). Four formulations (MMRP) were prepared using spray-drying and compared to a commercial sample (CMMRP). The MMRP formulation exhibited the highest encapsulation yield (91 %) and encapsulation efficiency (96 %), along with favorable physical properties, including a spherical shape and smooth surface.

A new species of mite in the genus Nenteria (Uropodina, Trematuridae), with a key to the Egyptian species.

We describe a new species of mite in the genus Nenteria Oudemans, collected from the Red Palm Weevil, Rhynchophorus ferrugineus (Oliver) (Coleoptera: Curculionidae), at Bahariya Oasis, Egypt. Nenteria bahariyaensis n. sp.

(Huds.) Opiz Exhibits Antihypertensive Effects by Inhibiting the Angiotensin-Converting Enzyme/Angiotensin II Type 1 Receptor Pathway in Human Endothelial Cells.

Overactivation of the angiotensin-converting enzyme (ACE)/angiotensin II type 1 receptor (AT1R) pathway leads to vasoconstriction and elevated blood pressure. (Huds.) Opiz is an herbal plant known for its antioxidant, anti-hyperlipidemic, and anti-atherosclerotic properties, with bioactive compounds that exhibit antihypertensive effects.
