Synthesis control of rhombic dodecahedral PtNiFe nanostructures for enhanced oxygen reduction reaction.

Platinum and platinum-based alloys have been reported to exhibit enhanced electrochemical properties in proton exchange membrane fuel cells and electrolyzers. The development of platinum alloy-based catalysts has focused on designing structures with highly active surfaces and optimizing the utilization of the noble metal Pt. In this study, we demonstrate the synthesis of novel nanostructures with a rhombic dodecahedral morphology through precursor syntheses of Pt, Ni, and Fe.

Effects of LM1215 on and .

Purpose: The aim of this study was to identify novel vaginal probiotics with the potential to prevent vulvovaginal candidiasis (VVC) and bacterial vaginosis (BV).

Materials And Methods: Eighteen strains of were isolated from healthy Korean women, and their antimicrobial effects against and were assessed. Three strains ( LM1203, LM1209, and LM1215) were selected for further investigation, focusing on their growth inhibition, biofilm regulation, and cellular mechanisms against these vaginal pathogens.

Synthesis of Tricyclic Tetrazoles by Cascade Diazotization/Intramolecular Radical C-H Heteroarylation of Arenes.

A cascade diazotization/intramolecular radical C-H heteroarylation of 1-benzyloxy-5-aminotetrazoles and 1-phenethyl-5-aminotetrazoles as substrates using sodium nitrite and acetic acid without any heating, catalysis, irradiation, or electrolysis is reported. This one-pot reaction afforded the desired tricyclic tetrazole products in good yields (up to 94%) without isolation of the diazonium salt intermediate under mild reaction conditions.

Smart Sensor Systems for Wearable Electronic Devices.

Wearable human interaction devices are technologies with various applications for improving human comfort, convenience and security and for monitoring health conditions. Healthcare monitoring includes caring for the welfare of every person, which includes early diagnosis of diseases, real-time monitoring of the effects of treatment, therapy, and the general monitoring of the conditions of people's health. As a result, wearable electronic devices are receiving greater attention because of their facile interaction with the human body, such as monitoring heart rate, wrist pulse, motion, blood pressure, intraocular pressure, and other health-related conditions.
