Halogen bonds have recently been identified as key contributors to directing sequential dynamics in multifunctional crystals, providing valuable insights for the advancement of ultrafast-response times in multilevel optical storage. These intermolecular interactions are characterized by the attraction between a halogen atom and another atom with lone pairs, typically a molecular entity with high electron density.

The debate surrounding the impact of circumcision on reducing the risk of HIV infection among men who have sex with men has been ongoing. A recent randomized controlled trial conducted by researchers from Sun Yat-sen University in China aimed to provide further insight into this issue. The study compared two groups of men who voluntarily
In the quest to reduce carbon emissions in Europe, renewable hydrogen has emerged as a key player. However, the method of sourcing and delivering this renewable energy source presents a complex set of challenges. A recent study by the Joint Research Centre (JRC) delves into the environmental impacts of different delivery methods for renewable hydrogen,
In a groundbreaking new study led by researchers from Curtin University, evidence has emerged that freshwater on Earth, a vital component for sustaining life, actually appeared much earlier than previously believed. The research, titled “Onset of the Earth’s hydrological cycle four billion years ago or earlier,” was recently published in the prestigious journal Nature Geoscience.
Methane is a greenhouse gas that is significantly more potent than carbon dioxide, approximately 25 times more powerful. When methane combines with water at low temperatures and high pressure, it forms methane hydrate, a solid compound similar to ice. These methane hydrate deposits are abundant under the seafloor, storing at least 1,800 gigatons of carbon.
The waste-to-wealth movement has sparked a wave of innovation in the field of technology aimed at converting greenhouse gases into valuable materials. One technology that has garnered significant attention is the catalytic conversion of methane into methanol, a versatile industrial solvent and raw material for chemical synthesis. The traditional industrial process for this conversion is
The aviation industry is experiencing a revolution with the incorporation of artificial intelligence (AI) into various aspects of its operations. Although airlines are not replacing pilots with AI anytime soon, industry experts believe that AI technology is already transforming the way airlines conduct business. Julie Pozzi, the head of data science and AI at Air
Per- and polyfluoroalkyl substances (PFAS) have become ubiquitous in our daily lives, from non-stick frying pans to stain-resistant sofas. These “forever chemicals” have been used since the 1950s due to their ability to repel water and oil, resist high temperatures, and act as surfactants. With over 15,000 different PFAS chemicals, each with at least two
The sunspot region that dazzled us with magnificent auroras in early May, AR 3664, has made a comeback in a grand fashion. After rotating out of view onto the far side of the Sun, it reappeared as AR 3697 on 27 May. With its return, it unleashed a series of powerful X-class flares, including an
Fatherhood is a significant life transition that can bring about various changes, including increased stress and responsibilities. A recent study conducted in the US has revealed that fathers tend to have poorer heart health compared to non-fathers. This article aims to delve deeper into the findings of this study and explore the implications it has
China’s Chang’e-6 lunar probe has made history by successfully landing on the far side of the Moon to collect samples, marking a significant milestone for Beijing’s space program. This achievement was reported by state media and signifies a major leap forward for China’s decades-old space exploration efforts. The probe touched down in the vast South
The history of Earth is marked by several significant events that shaped the course of life as we know it today. Among these events, the Great Ordovician Biodiversification Event stands out as a pivotal moment in evolutionary history. This 30-million-year period saw an explosive burst of biodiversity, with the emergence of countless new species that
Nvidia’s CEO, Jensen Huang, recently shared his vision for the future of artificial intelligence during his keynote speech at Computex in Taipei. He emphasized the idea that the next industrial revolution has already begun, with AI playing a central role in shaping the future of technology. Companies and countries around the world are partnering with
Metal halide perovskites have been a topic of interest in the field of optoelectronics due to their remarkable properties. Among these materials, tin (Sn) halide perovskites have shown promise in the fabrication of p-type transistors with impressive hole mobilities exceeding 70 cm2 V-1 s-1. However, the development of n-type transistors using perovskite channels based on
In recent years, Japan has seen a surge in tourism, with more visitors flocking to the country than ever before. One of the country’s most private attractions, the high-tech toilet, has gained international attention and is now considered a must-have in luxury bathrooms worldwide. These bidet toilets, equipped with warm seats and precision spray technology,
