In a recent breakthrough published in Optics & Laser Technology and Infrared Physics & Technology, a research team led by Prof. CHENG Tingqing at the Hefei Institutes of Physical Science of the Chinese Academy of Sciences have introduced a novel low-thermal-effect gradient-doped crystal to tame thermal effects and improve brightness of high-power end-pumped Nd:YAG lasers.

For over a century, the well-known 18-electron rule has guided the field of organometallic chemistry. Now, researchers at Okinawa Institute of Science and Technology (OIST) have successfully synthesized a novel organometallic compound that challenges this longstanding principle. They have created a stable 20-electron derivative of ferrocene, an iron-based metal-organic complex, which could lead to exciting possibilities in chemical science.  

In the production of dimethyl carbonate (DMC), a versatile chemical critical for manufacturing lithium-ion battery electrolytes, pharmaceuticals and high-performance polymers, an ultra-high purity (≥99.95%) is needed to meet stringent industrial standards. Melt crystallization, as a green manufacturing method is highly important for this purpose; however, the widespread adoption of this technology has been hindered by complex heat and mass transfer phenomena, which can lead to uneven crystal growth and suboptimal yields.

Patients with glioblastoma (GBM)—a type of brain cancer—have a poor prognosis owing to the aggressive nature of GBM disease and limited GBM treatment options. A new study by researchers from Croatia provides critical insights into the transformative role of artificial intelligence (AI) in advancing the diagnosis and treatment of GBM. From accurately distinguishing tumor tissue in GBM to enabling personalized treatment, AI-based tools and models can revolutionize GBM treatment and care.

A study led by UC San Diego biologists is calling attention to the availability of food for bees in the Southwestern U.S. Non-native honey bees, the study found, extract an overwhelming majority of pollen from regional flowers, posing a significant ecological threat to native bee species.

The control model, devised by a team from the University of Cordoba, makes it possible to reduce the waste of an essential and limited resource and to extend the useful life of pipes

Positively and neutrally buoyant microplastics mainly outflow from the Seto Inland Sea into the Pacific Ocean, whereas negatively buoyant MPs hardly leave the Seto Inland Sea and are primarily deposited and degraded near river mouths. Traditional microplastics are difficult to degrade quickly and thus remain in the marine environment for long periods. However, the use of biodegradable microplastics can significantly reduce microplastic pollution in the marine environment, especially in sediments.
