A Comprehensive Review on Premature Hair Graying: Factor Contributing, Pathogenesis, Prevention Strategies, and Natural Therapeutic
Abstract: Premature graying of hair (PGH), also known as early canities, is an increasingly common dermatological concern characterized by the loss of natural hair pigmentation before the expected age. Hair color is primarily determined by the quantity and type of melanin synthesized by melanocytes within the hair follicle. Disruption in melanocyte function, survival, or melanin synthesis leads to hair graying. Multiple intrinsic and extrinsic factors contribute to PGH, including genetic predisposition, …

Thermal Dissipation Performance of Metal–Polymer Composite Heat Exchanger for Enhanced Thermal Management in Compact Electric Geysers
Abstract: Most electric geysers these days are made from all-metal stuff, like stainless steel tanks and copper coils for heating, plus mild steel on the outside. Standby heat losses can be 20 to 40 watts, and a 15-litre unit weighs around 6 to 8 kilograms. Manufacturing costs are higher, too. Hard water makes it worse, with limescale building up on the heating elements and cutting thermal conductivity by 10 to 30 …

Electrochemical Evaluation of Corrosion Behavior in Industrial Alloys Under Acidic and Marine Conditions
Abstract: Corrosion represents a spontaneous physicochemical transformation in which metals revert to their more stable thermodynamic state, typically oxides, hydroxides, or sulfides, as a result of interaction with environmental elements. Rather than being a simple surface reaction, corrosion is a complex electrochemical phenomenon that significantly influences the durability, reliability, and performance of metallic structures across industrial, marine, and domestic sectors. The consequences extend beyond material degradation, contributing to substantial economic losses, …
