A ZnS-SnS-NiCoS composite was fabricated on Ni foam by polymetallic compositing of NiS. The optimized catalyst exhibits outstanding OER performance with a low overpotential (149 mV at 10 mA cm) and Tafel slope (33.57 mV dec), offering a promising strategy for efficient water splitting and sustainable hydrogen production.

Electrochemical nitrogen fixation-a sustainable pathway for converting abundant N into NH using renewable energy-holds transformative potential for revolutionizing artificial nitrogen cycles. Nevertheless, even the state-of-the-art catalytic systems also suffer from inadequate N adsorption capacity, which critically limits ammonia production rates and Faradaic efficiency (FE). To overcome this bottleneck, we strategically leveraged the antiferroelectric properties of SnO to establish dipole-dipole interactions with N molecules, synergistically enhancing both N adsorption and activation kinetics.

Anastrepha obliqua, a neotropical pest widely distributed in the Americas, attacks mango and other tropical fruits. In Mexico, it is controlled through integrated pest management, using the Sterile Insect Technique (SIT) as a main component. The applicability of SIT is significantly improved with the use of genetic sexing strains (GSS) that allow the possibility to release exclusively sterile males, the primary component of the technique.

Alzheimer's disease (AD) is a neurodegenerative disease characterized by progressive cognitive impairment and neuronal loss, with pathological hallmarks including Aβ plaque deposition and tau tangles. At present, the early diagnosis and treatment of AD still face great challenges, such as limited diagnostic methods, difficulty in blood-brain barrier (BBB) penetration, complex disease mechanisms, and lack of highly effective targeted therapies. Antibody drugs have shown broad prospects in the field of AD due to their high specificity, engineering and multifunctional therapeutic potential, include targeted Aβ clearance, tau pathological regulation, imaging probes, and blood biomarkers.

Cancer immunotherapy represents a transformative strategy in modern oncology, utilizing the body's immune system to recognize and eliminate malignant cells with precision. Unlike traditional therapies, which often directly target the tumor, immunotherapy enhances the immune system's inherent ability to differentiate between healthy and cancerous cells. The advent of immune checkpoint inhibitors (ICIs), particularly those targeting the PD-1/PD-L1 and CTLA-4 pathways, has marked a significant breakthrough in this field.

Background: Pediatric patients with autoimmune and inflammatory diseases often require immunosuppressive therapy, which increases their susceptibility to infections, including varicella-zoster virus (VZV). While the live attenuated varicella vaccine is contraindicated in most immunocompromised children, the recombinant subunit vaccine, Shingrix, may offer an alternative preventive strategy. However, data on its safety, immunogenicity, and efficacy in pediatric VZV-naïve patients remain limited.
