The production of hydrogen through water splitting using solar energy or other renewable resources is seen as a promising method for sustainable hydrogen production on a large scale. However, most photoelectrochemical water splitting systems currently available are either inefficient, unstable, or not suitable for large-scale implementation. Researchers at the Ulsan National Institute of Science and

Living and working on the Moon is no easy feat, with a multitude of challenges and dangers to overcome. One of the most critical aspects for successful lunar exploration is having a reliable source of power. To address this need, NASA has embarked on the Fission Surface Power Project as part of its upcoming Artemis
An alarming and catastrophic scenario of an abrupt halt in the Atlantic Ocean currents, with the potential to plunge large parts of Europe into a deep freeze, is becoming increasingly likely according to a new complex computer simulation. This simulation has identified a “cliff-like” tipping point in the future, indicating that the nightmare scenario may
Indoor air pollution is a major concern for human health, with volatile organic compounds (VOCs) being a significant contributor. Among the various VOCs, formaldehyde stands out as a common pollutant emitted by household items and can have adverse health effects. However, current sensors lack the sensitivity and selectivity to detect formaldehyde at low concentrations. In
Quantum computing has long been hailed as the future of technology, promising unparalleled speed and memory usage. It has been seen as a paradigm shift from classical computing, which processes information using digital bits. However, recent research suggests that classical computing may have the potential to outperform state-of-the-art quantum computers in certain scenarios. This article
In the field of photochemistry, the search for highly reducing or oxidizing photocatalysts has always been a significant challenge. Previous studies have mainly focused on transition metal complexes with precious metals, such as ruthenium and iridium. However, these complexes come with their limitations, including the need for high energy light for excitation and the high
Researchers at the University of Cincinnati have made significant progress in the conversion of carbon dioxide into valuable products. Led by Associate Professor Jingjie Wu, the team has discovered that by using a modified copper catalyst, the electrochemical conversion of carbon dioxide into ethylene can be enhanced. Ethylene is a vital component in the production
Quantum information technology heavily relies on the use of single photons as qubits. Accurately determining the number of photons is crucial in various quantum systems such as quantum computation, quantum communication, and quantum metrology. The development of photon-number-resolving detectors (PNRDs) has been a key focus in achieving this accuracy. PNRDs have two main performance indicators:
Quantum researchers from Cornell University have made a groundbreaking discovery, successfully detecting the elusive Bragg glass phase using advanced data analysis techniques and large volumes of X-ray data. The research, titled “Bragg glass signatures in PdxErTe3 with X-ray diffraction Temperature Clustering (X-TEC),” was published in the prestigious journal Nature Physics. Led by postdoctoral researcher Krishnanand
The discovery and understanding of new quantum phases in materials is a crucial area of research in the field of physics. One of these fascinating phases is the excitonic insulator, which arises from the condensation of excitons with non-zero momentum. Recently, a team of researchers from various institutions, including Shanghai Jiao Tong University, explored the
A groundbreaking study conducted by RIKEN chemists has led to the isolation of an elusive structure involving two water molecules that had previously only been predicted but never observed. This significant finding has the potential to impact various fields, ranging from astrochemistry to the corrosion of metals. The research, which has been published in The
In a stunning turn of events, a river of magma beneath an Icelandic fishing village has captured the attention of scientists worldwide. Late last year, a volcanic eruption on the western Reykjanes peninsula revealed a previously unknown level of magma flow. This region had not witnessed an eruption in 800 years, hinting at a reawakening
OpenAI’s CEO, Sam Altman, has set his sights on an ambitious mission to reshape the global semiconductor industry. Recognizing the pressing challenges faced by the rapidly expanding artificial intelligence (AI) sector, Altman aims to tackle one of its significant obstacles: the scarcity of costly computer chips essential for powering large-language models such as OpenAI’s ChatGPT.
The Moon, our natural satellite, may seem unchanging and eternal, but recent studies suggest otherwise. Scientists in the United States have discovered that the Moon is gradually shrinking in size as it cools down. Although this process occurs at a gradual pace, approximately 45 meters (more than 150 feet) every few hundred million years, it
In the pursuit of understanding the secrets behind exceptional longevity, scientists have long been fascinated by centenarians and nonagenarians. These individuals who live beyond the age of 90 not only provide insights into how to live longer but also offer clues on how to age in better health. While previous studies on centenarians have been
