A machine learning assisted approach to classify rose species and varieties with laser induced breakdown spectroscopy.

Background: Classification of rose species and verities is a challenging task. Rose is used worldwide for various applications, including but not restricted to skincare, medicine, cosmetics, and fragrance. This study explores the potential of Laser-Induced Breakdown Spectroscopy (LIBS) for species and variety classification of rose flowers, leveraging its advantages such as minimal sample preparation, real-time analysis, and remote sensing.

Stimulation of the production of proteases from Penicillium verrucosum isolated from Egyptian soil.

The uses of proteolytic enzymes in manufacturing procedures are numerous. Researchers are investigating a number of strategies to find, rework, or artificially produce enzymes with improved suitability for manufacturing processes in light of the growing needs and uses. Alkaline protease production was assessed in fungal strains that were obtained from soil using the serial dilution technique.

Layer-by-Layer Assembled Perovskite/Polymer Photoelectrochemical Devices with Enhanced Performance and Stability.

Organic-inorganic hybrid perovskites (OIHPs) offer a promising pathway for the development of low-cost and efficient solar hydrogen production systems. Despite remarkable advancements, poor chemical stability of the OIHPs in aqueous environments limits their practical applications. Herein, we design a photoelectrochemical (PEC) device consisting of layer-by-layer assembled P(VDF-TrFE)/CHNHPbBr (MAPbBr) hybrid films that simultaneously achieve efficient and stable solar water splitting.

Outcomes After Heart Transplantation in Adults with Congenital Heart Disease - A Single Center Experience.

Background: The purpose of this study was to describe outcomes after heart transplantation in adults with congenital heart disease (CHD) based on the experience from a high volume transplant center.

Method: Retrospective cohort study of adults with CHD who underwent heart transplantation at Mayo Clinic Rochester, MN (2003-2024).

Results: Of 89 patients (age 40 [9;66], 52% males) who underwent heart transplantation, 67 (75%) had biventricular physiology while 22 (25%) had Fontan physiology.

Next-generation electrochemical etching for III-nitride semiconductors: Innovations, applications, and beyond.

Electrochemical etching (ECE) has become an essential approach for nanostructuring III-nitride semiconductors, offering precise, scalable control over their physical and functional characteristics. Through ECE, bulk materials such as GaN, InN, and InGaN can be engineered into zero-dimensional nanoparticles, one-dimensional nanowires, and two-dimensional porous frameworks. These nanostructures exhibit enhanced optoelectronic behavior, superior charge transport, and increased surface area properties that make them highly effective at photodetection and gas sensing.
