The longest single crystal structure confirmed azaacene derivative: one step forward large conjugation molecules
Organic semiconductors are supposed to be the next generation semiconductors, which shows many great advantages over silicon. For example, their devices are easier and cheaper for fabricating and can be flexible. Their variable molecular structures can be
Wind turbines, spiral staircases, and springs—these are a few examples of helices in everyday life. The helix is also a reoccurring concept in mythology, spanning many cultures. In biology, helices are both essential and pervasive. Collagen, the
Rheumatoid arthritis (RA) is the most common type of autoimmune disease. It is triggered by a faulty immune system of the body. However, the real cause of the disease is not completely known. The disease affects the
The presence of plastics on the marine environment has several dangerous effects on the aquatic living organisms. Plastics have high chemical stability and are invariant with respect to the degradation agents. Their accumulation on sea surface produces
Linear multi-atom complexes of Group 11 metals (Cu, Ag, Au) exhibit fascinating luminescence properties that make them highly interesting 1) for the systematic design of molecular wires in nanoelectronics and 2) their application as light-emitting building blocks
Among many pulmonary diseases, according to the 2014 WHO report, Tuberculosis (TB) is considered as one of the deadliest communicable diseases. While TB cure rates over 90% have been documented in resource-rich countries, its detection and treatment
It was reported that exposure to dental diagnostic X-rays in oral, dental and maxillofacial care increases the risk of benign tumors (meningioma), but not of malignant brain tumors (glioma). Malignant gliomas grow more rapidly. Meningioma, a benign
When a baby is born, a simple blood test reveals whether the child has PKU, which is a recessive genetic disorder where the body fails to regulate the amount of phenylalanine (Phe) in blood. Phe is a
A buckle fracture of the distal radius (wrist bone) is a very minor fracture and the most common fracture in childhood. A “buckle” fracture occurs when there is a wrinkling of the outer edge of the bone
Investigation of the molecular structure of SiCl4 using gas electron diffraction (GED) was the topic of my research I picked up when I started my graduate study at Department of Chemistry, the University of Tokyo. However, initial
Physics is often thought to be quite irrelevant to Biochemistry and Medicine. But, the very first Physics Nobel Prize in 1901, for the discovery of X-rays, is highly related to Medicine nowadays. This clearly shows that a
Cancer is one of the major diseases in the 21st century. Hundreds of billions of dollars have been spent on cancer research in the last half century, but still, our understanding of the disease mechanisms is limited.
President Eisenhower’s “atoms for Peace” initiative started the movement to explore peaceful uses of radioactive atoms, and today one use of radioactivity is to diagnose and treat diseases. Radioactive atoms are unstable atoms that decay by characteristic
Olfactomedin-1 is a signaling protein in the brain that plays various roles during early brain development. Brain cells (neurons) secrete the protein to the extracellular matrix, where it is known to be involved in several signaling pathways.
