Novel magnetic nanocomposite FeO@CS@PHMG as an effective and recyclable antimicrobial material for hospital wastewater disinfection.

Hospital wastewater (HWW) is a major pollutant that presents significant risks to both environmental and human health. In this study, we developed a novel, inexpensive and highly antibacterial magnetic nanocomposite composed of FeO nanoparticles synthesised from spent pickling liquors, coated with chitosan and then integrated with polyhexamethylene guanidine hydrochloride (FeO@CS@PHMG) using sodium tripolyphosphate (TPP) as a crosslinking agent. The obtained results revealed that the synthesised nanocomposite exhibited high antibacterial activity against and .

A novel polymer composite from polyhexamethylene guanidine hydrochloride for high performance triboelectric nanogenerators (TENGs).

In this study, we report the successful fabrication of a novel antibacterial triboelectric nanogenerator (TENG) using a polymer composite film based on polyhexamethylene guanidine hydrochloride (PHMG). The composite materials, with optimised ingredient ratios, consist of PHMG, polyvinyl alcohol (PVA) and glutaraldehyde (GA) as a crosslinking agent (PHMG-GA-PVA). Utilising 3D printing, these composite materials were directly deposited on the conductive substrates and used as positive TENG electrodes.

Cultural adaptation of an evidence-based intervention to address mental health among youth affected by armed conflict in Colombia: An application of the ADAPT-ITT approach and FRAME-IS reporting protocols.

Background: In Colombia, over 9 million people have been impacted by armed conflict, creating a significant need for mental health services. This study aimed to culturally adapt and pilot test the Youth Readiness Intervention (YRI), an evidence-based transdiagnostic mental health intervention, for conflict-affected Colombian youth aged 18-28 years.

Methods: The eight phases of the Assessment, Decision, Administration, Production, Topical Experts, Integration, Training, and Testing (ADAPT-ITT) framework were used to culturally adapt the YRI for conflict-affected Colombian youth.

Optimization of Culture Conditions for High Cell Productivity and Astaxanthin Accumulation in Vietnam's Green Microalgae HB and a Neuroprotective Activity of Its Astaxanthin.

Background: , a green microalga, is a rich source of natural astaxanthin and a potent antioxidant with high commercial value. This study investigates the biological characteristics and potential of HB isolated from Hoa Binh, Vietnam, for growth and astaxanthin accumulation using a two-phase culture method.

Methods: HB was cultured in a C/RM medium at 25 °C, and morphological characteristics were examined.
