HONG KONG (15 December 2024) --- A breakthrough in antenna technology that could revolutionise the future of wireless communications, particularly for the upcoming 6th generation (6G) networks, has been announced by a research team led by Professor Chan Chi-hou, Chair Professor of the Department of Electrical Engineering at City University of Hong Kong (CityUHK).

In a paper published in SCIENCE CHINA Chemistry, a facile and applicable method to in-situ modify the Al anode surface with F–Al–O chemical bonds has been developed, which could preferentially induce the planar growth of Al on Al anode, thus leading to the dendrite-free morphology evolution and improved cycling stability of Al metal batteries. This work provides novel insights on low-cost and facile strategies against the Al dendrite growth in rechargeable aluminum batteries.

In an LED, electroluminescence creates light through charge carriers that cause the semiconductor to emit photons. This emission can require more energy than is present in the semiconductor, and this excess energy comes from heat around the semiconductor. This makes a semiconductor into a cooling device. In this study, researchers proposed a way to improve the performance of this electroluminescent cooling by using multilayer semiconductors.

It is the first very high-energy flaring episode recorded from M87 since 2010. The data were collected by the Event Horizon Telescope (EHT) collaboration during a multi-wavelength observational campaign in 2018, using numerous orbiting telescopes such as NASA's Fermi, HST, NuSTAR, Chandra, and Swift, along with three of the largest Cherenkov telescopes: H.E.S.S., MAGIC, and VERITAS

This study investigates the safety and efficacy of lentivirus-modified hematopoietic stem cell gene therapy (HSCGT) for treating advanced symptomatic juvenile metachromatic leukodystrophy (MLD). MLD is a genetic lysosomal storage disease characterized by the dysfunction of arylsulfatase A (ARSA) or its activator prosaposin (PSAP), leading to the accumulation of sulfatides in the nervous system. The study found that HSCGT is safe and provides clinical benefits to patients with post-symptomatic juvenile MLD.

Recently published research from the University of Oklahoma and the University of Tulsa shows that a new therapy for children with chronic nightmares reduced the number of nightmares and the distress they caused and increased the number of nights a child slept without waking. The study, published in Frontiers in Sleep, is thought to be the first randomized clinical trial to test a nightmare therapy in children, and it marks a step toward treating nightmares as a distinct disorder and not solely a symptom of another mental health issue.
