Photocatalysts that are highly reducing or oxidizing are a major challenge in the field of photochemistry. Up until now, only a small number of transition metal complexes, specifically those with Earth-abundant metal ions like chromium, iron, and cobalt, have been successful in becoming excited state oxidants. However, these photocatalysts require high energy light for excitation

The University of Cincinnati’s team of engineers, led by Associate Professor Jingjie Wu, has made significant strides in the conversion of carbon dioxide into valuable products. This breakthrough not only addresses climate change but also offers a more efficient method for producing ethylene, a crucial component in the creation of various products, including plastics. With
Ribosomes are essential in the process of protein synthesis, acting as the cell’s “protein factories.” They consist of two subunits, with the small subunit responsible for reading the messenger RNA (mRNA) and the large subunit responsible for protein synthesis. While the assembly of ribosomes is well-understood, the degradation process has remained a mystery. However, a
In recent years, there has been a growing trend of consumers opting for “green” cleaning products, under the assumption that these alternatives are safer for their health and the environment. However, a new study conducted by researchers at the University of York reveals a disturbing truth – many of these so-called “green” cleaners emit just
Artificial intelligence (AI) has been rapidly gaining significance in the field of chemical research, providing new avenues to tackle complex challenges that traditional approaches struggle with. Within the realm of AI, machine learning has emerged as a dominant subtype in chemistry, utilizing algorithms and statistical models to make decisions based on data and perform tasks
The production of aluminum generates an astonishing 180 million tons of toxic red mud annually. This waste poses significant environmental challenges due to its high alkalinity and traces of heavy metals. However, scientists at the Max-Planck-Institut für Eisenforschung have made a groundbreaking discovery. They have developed a process that converts the iron oxide in red
Plastic has long been a cause for concern due to its detrimental impact on the environment and human health. From its pervasive presence in soil and oceans to the discovery of microplastics in the human body, the urgent need to reduce plastic usage has become increasingly evident. In response to this global challenge, a team
In recent years, the development of organic semiconductors has gained significant attention in the scientific community. Unlike conventional rigid semiconductors based on silicon, organic molecules have the potential to be flexible, ductile, and lightweight, opening up new possibilities for designing semiconductor devices. Chemists at RIKEN have made a groundbreaking discovery in the field by developing
The development of efficient and reliable gas detection sensors plays a crucial role in ensuring safety in various industries. In Australia, a team of engineers from RMIT University, the University of Melbourne, and the ARC Centre of Excellence for Transformative Meta-Optical Systems (TMOS) has recently made a breakthrough in gas detection technology. They have successfully
In a groundbreaking development, the research group led by Prof. Polshettiwar at Tata Institute of Fundamental Research (TIFR) in Mumbai has pioneered a novel catalyst that defies the common instability of reduction catalysts in the presence of air. This “plasmonic reduction catalyst stable in air” combines platinum-doped ruthenium clusters with “plasmonic black gold.” The unique
The University of Massachusetts Amherst research team has achieved a significant breakthrough in the modeling and understanding of intrinsically disordered proteins (IDPs) and their spontaneous phase separation. IDPs are critical in numerous biological functions and are linked to cancer, neurodegenerative disorders, and infectious diseases. However, studying and describing the process of phase separation has been
The traditional understanding of protein formation involves complex biological processes within cells. However, R. Graham Cooks, the Henry B. Hass Distinguished Professor of Chemistry, and his postdoctoral researcher Lingqi Qiu have uncovered experimental evidence challenging this long-held belief. Their recent publication in the Proceedings of the National Academy of Sciences presents a groundbreaking discovery –
