A groundbreaking technology has emerged to revolutionize the production of green hydrogen by addressing the limitations of current catalyst electrodes. Led by a team of researchers from the Department of Materials Science and Engineering and the School of Energy and Chemical Engineering at UNIST, along with collaborators from King Abdullah University of Science and Technology
The increasing shift towards a sustainable future, particularly in the transportation and energy sectors, is expected to lead to a significant rise in demand for key raw materials such as cobalt, lithium, copper, aluminum, iron, and rare earth elements. According to a recent study conducted by the Berlin-based climate research institute MCC, global demand for
Circumcision has long been a topic of discussion when it comes to its potential impact on reducing the risk of HIV transmission among men who have sex with men. While observational studies have pointed towards the benefits of circumcision in preventing STIs like HIV, there has been ongoing debate due to potential sampling biases. However,
Renewable hydrogen has been identified as a key player in reducing carbon emissions across Europe. Research conducted by the Joint Research Centre (JRC) suggests that sourcing hydrogen from regions with cheaper renewable energy sources may be more cost-effective than local production. However, concerns have been raised regarding the environmental impact of transporting large quantities of
The process of converting methane into methanol is currently energy and resource-intensive, relying heavily on rare and expensive transition or noble metals. While catalyst systems for direct oxidation of methane to methanol have been developed in the past decade, most of them have been using these costly metals. A recent study by a group of
Recent research led by Dr. Hamed Gamaleldien and Dr. Hugo Olierook from Curtin University has uncovered evidence suggesting that fresh water on Earth appeared much earlier than previously believed. By examining ancient crystals from the Jack Hills in Western Australia, the researchers have dated the onset of Earth’s hydrological cycle to about 4 billion years
Methane is a powerful greenhouse gas that is about 25 times more potent than carbon dioxide. When combined with water at low temperatures and high pressure, it forms methane hydrate, which is an ice-like solid found in large deposits under the seafloor. Estimates suggest that there are at least 1,800 gigatons of carbon stored in
The aviation industry is on the brink of a significant transformation due to the integration of artificial intelligence (AI) technology. While the idea of AI replacing pilots may still be far-fetched, experts in the field believe that AI is already revolutionizing the way airlines operate. Julie Pozzi, the head of data science and AI at
The sunspot region AR 3697 has made a grand comeback after rotating away from view onto the far side of the Sun in the middle of May. This region, previously known as AR 3664, has been causing quite the commotion with its unpredictable behavior. Just when we thought it had quieted down, it decided to
From non-stick frying pans to stain-resistant sofas, some of the most innovative everyday products are made using chemicals known as per- and polyfluoroalkyl substances (PFAS). These “forever chemicals” have been utilized since the 1950s due to their ability to repel water and oil, resist high temperatures, and act as surfactants. With around 15,000 different PFAS
China’s Chang’e-6 lunar probe made history on Sunday as it successfully landed on the far side of the Moon to collect samples. This monumental achievement marks the latest leap for Beijing’s space program, showcasing the country’s dedication to advancing its presence in space exploration. The probe touched down in the vast South Pole-Aitken Basin, an
Fatherhood has been found to have a significant impact on the heart health of individuals, particularly in later stages of life. The stress and responsibilities associated with parenting may make it challenging for men to maintain healthy lifestyle habits, resulting in poorer heart health outcomes. A longitudinal, multi-ethnic US study conducted by researchers has shed
Metal halide perovskites have emerged as a promising class of materials with exceptional optoelectronic properties, paving the way for the development of cost-effective thin-film transistors. Recent advancements in this field have primarily focused on utilizing tin (Sn) halide perovskites to create high-performance p-type transistors. However, the challenge lies in achieving similar success with n-type transistors,
The study conducted by Johns Hopkins University researchers sheds new light on the significant role that prehistoric worms and other invertebrates played in sparking a chain of events that led to the Great Ordovician Biodiversification Event, which occurred approximately 480 million years ago. These small creatures, which no longer exist today, were found to have
