A randomized controlled trial investigating the effect of thermal steam spray on nasal condition, neurological function, and sleep quality in young adults with nasal congestion and irregular sleep patterns

<title>Abstract</title> <bold>Background</bold> Intranasal thermal steam spray (ITSS) has been suggested to relieve nasal stuffiness and improve sleep-related symptoms. However, its effects on respiratory capacity, neurological functions, including autonomic nervous system (ANS)...

Ultrasound-assisted esterification of levulinic acid for sustainable butyl levulinate production over tin(II)-modified silicotungstic acid supported on activated bentonite

Leveraging ultrasound irradiation and Brønsted–Lewis acid synergy, butyl levulinate (BL), a promising bio-based fuel additive, was synthesized by esterifying levulinic acid (LA) with n -butanol over tin(II)-modified silicotungstic acid supported on activated bentonite (Sn x STA/a...
