The hydrolysis of levan using compressed hot water for the production of functional fructooligosaccharides (FOSs) was investigated. Levans from (EH) and (HS) were characterized using scanning electron microscopy and light scattering techniques, and hydrolyzed using compressed hot water at four temperatures (120, 140, 160, and 180°C). The hydrolysates were analyzed using high-performance liquid chromatography and electrospray ionization-mass spectrometry. Levan HS showed a crystalline morphology, whereas levan EH showed an aggregated structure. Both levans had molar masses on the order of 10 g/mol, but levan EH had a smaller radius of gyration, hydrodynamic radius, and intrinsic viscosity. Levan EH hydrolyzed into FOSs at approximately 120°C, whereas levan HS required a temperature of at least 160°C, possibly because of differences in the degree of branching of the two levans. Both samples were degraded to fructose when treated at 180°C.

Department of Public Health, Federal University of Technology Owerri, Owerri, Imo State, Nigeria.
Background: Umbilical cord care is an important aspect of newborn health, and different practices exist around the world, often influenced by cultural, healthcare infrastructure, and socioeconomic factors. The objective of this systematic review is to synthesize current literature on umbilical cord care practices in Nigeria, with an emphasis on the impact of cultural beliefs, healthcare infrastructure, and socioeconomic factors.
Methods: A comprehensive search for literature was performed across PubMED, MEDLINE and Google scholar for studies published between 2010 and 2023.
The Complex Valorization of Black Alder Bark Biomass in Compositions of Rigid Polyurethane Foam.
Materials (Basel)
December 2024
Latvian State Institute of Wood Chemistry, Dzerbenes Street 27, LV-1006 Riga, Latvia.
The use of black alder (BA) bark biomass in rigid polyurethane (PUR) foam compositions was the main task of investigation. Extractive compounds isolated from the bark through hot water extraction were used as precursors for bio-polyol synthesis via acid-free liquefaction with the polyether polyol Lupranol 3300 and through oxypropylation with propylene carbonate. The OH functionality and composition of the polyols were analyzed via wet chemistry and FTIR spectroscopy.

To this day, energy conservation, emission reduction, and environmental protection continue to be goals pursued by humanity. Passive radiation cooling, as a zero-consumption refrigeration technology, offers substantial opportunities for reducing global energy consumption and carbon dioxide emissions. It is of great significance to develop high-performance passive radiation cooling materials from sustainable materials.

Ball bearings face numerous challenges under harsh operating conditions of elevated pressure between the balls and other contacting parts of the bearing like drop in tribological properties. To address these challenges, this paper presents the first successful experimental investigation of incorporating an innovative hexagonal boron nitride (h-BN) into Aluminum-Carbon nanotube (Al-0.6 wt% CNTs) nanocomposites.

Background/objectives: This project aims to provide valuable insights into the formulation of orodispersible films (ODFs) for the delivery of PROTAC ARV-110. The primary objective of this drug delivery formulation is to enhance the solubility of PROTAC ARV-110, which faces significant challenges due to the low solubility of this active pharmaceutical ingredient, as it belongs to a molecular class that is considered to exceed the "Rule of Five".
Methods: We employed the concept of developing a rapidly disintegrating ODF to enhance the solubility of PROTAC ARV-110, utilizing polyvinyl alcohol as the polymer of choice.
