Calcite, a crystalline form of calcium carbonate, is a mineral with a rhombohedral appearance that is abundant on Earth. As a major component of limestone and marble, calcite is known for its stability compared to other forms of calcium carbonate, such as aragonite and vaterite. The internal structure of calcite is a key factor in

Food safety is a critical issue that affects consumers worldwide. The constant threat of contamination from harmful pathogens can lead to serious illnesses and even fatalities. Traditional methods of pathogen detection, such as cell culture and DNA sequencing, have limitations that make it difficult to detect contaminants in a timely and efficient manner. These methods
For years, the process of testing for asbestos in construction materials and air samples has relied heavily on transmission electron microscopy (TEM). However, recent research conducted by the National Institute of Standards and Technology (NIST) has suggested that scanning electron microscopy (SEM) may be a viable alternative to TEM for asbestos identification and classification. Asbestos,
Hydrocarbazole plays a crucial role in organic chemistry as a building block for various biologically active compounds, ranging from pesticides to anticancer drugs. The synthesis of these compounds is a significant area of research, with the Diels-Alder reaction being one of the most reliable methods for this purpose. Over the last decade, Professor Shinji Harada
The study published in Science Advances by Northwestern investigators led by Chad Mirkin, Ph.D., sheds light on how manipulating DNA chemistry can lead to the creation of new materials with applications in medicine and the life sciences.

Water, an essential compound for life, is known for its unique properties that set it apart from other substances. One of the many peculiarities of water is the behavior of its molecules at the interface with air. While the majority of water molecules exhibit typical hydrogen bonding patterns, those at the surface experience different interactions.
Chemistry has always been a field that requires precision and innovation. A recent study conducted by a team of chemists at the University of Bremen in Germany has opened up a world of possibilities by developing a new type of nitrene with slow-reacting capabilities. This breakthrough, published in the prestigious journal Science, could revolutionize the
In a recent collaborative research project between the University of Leiden and the John Innes Centre, a groundbreaking discovery was made in the field of antibiotic development. The project involved screening a chemical library of 352 small molecules that are currently being used in human therapies for cancer, but have not been tested for their
Somatostatin receptors (SSTRs) are a vital group of G protein-coupled receptors (GPCRs) with significant roles in hormone regulation and tumor inhibition. Among the five subtypes, SSTR5 is highly expressed in the pituitary gland, making it a potential target for treating endocrine disorders and hormonal imbalance-related tumors. A recent study published in PNAS by a research
The realm of molecular reactions is a fascinating yet complex world that requires a keen eye and specialized equipment for observation. Just like capturing tiny lava flows during a volcanic eruption, filming molecular actors like covalent organic frameworks (COFs) demands precision and innovation. With the potential to revolutionize battery technology and hydrogen production, understanding the
Organ preservation has always been a challenge in the field of medical advancements, with cryogenic damage posing a significant barrier to effective organ transplantations and treatments.
