Halogen bonds play a significant role in directing sequential dynamics in multi-functional crystals, offering insights essential for developing ultrafast-response times for multilevel optical storage. These intermolecular interactions arise from the attraction between a halogen atom and another atom with lone pairs, contributing to the development of innovative photo-functional materials. Despite the crucial role of halogen

The waste-to-wealth movement has sparked a renewed interest in technologies that can convert greenhouse gases into valuable materials. Among these technologies, the catalytic conversion of methane into methanol has emerged as a promising solution. Methanol is a widely used industrial solvent and raw material for various chemical synthesis processes. However, the traditional industrial process for

Recent research led by Curtin University has challenged previously held beliefs about the emergence of fresh water on Earth. According to the study titled “Onset of the Earth’s hydrological cycle four billion years ago or earlier,” published in the journal Nature Geoscience, evidence suggests that fresh water appeared on Earth around 4 billion years ago.

Per- and polyfluoroalkyl substances (PFAS) have been commonly used in everyday products since the 1950s due to their unique properties such as water and oil repellency, resistance to high temperatures, and surfactant abilities. There are approximately 15,000 different PFAS chemicals, all characterized by their strong carbon-fluorine bonds that make them resistant to degradation. As a

China’s Chang’e-6 lunar probe recently made headlines as it successfully landed on the far side of the Moon to collect samples. This marked a significant milestone for Beijing’s space program, which has been making steady progress over the years. The probe touched down in the South Pole-Aitken Basin, a massive impact crater that is one

A recent study conducted in the United States has shed light on the impact of fatherhood on heart health. The research, which is the first of its kind to examine the longitudinal and multi-ethnic aspects of fatherhood and cardiovascular health, revealed some concerning trends. One of the key findings of the study was that fathers

Metal halide perovskites have gained significant attention in recent years due to their remarkable optoelectronic properties. Among these materials, tin (Sn) halide perovskites have shown great potential in fabricating p-type transistors with impressive field-effect hole mobilities. However, the development of n-type transistors based on perovskite channels has been challenging, limiting the potential for complementary logic

The evolutionary history of Earth is marked by periods of rapid biodiversity growth, with one of the most significant bursts dating back to roughly 480 million years ago during the Great Ordovician Biodiversification Event. A recent study conducted by researchers at Johns Hopkins University suggests that this explosion of new species may have been catalyzed
