The research team led by Prof. DU Pingwu from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) first successfully synthesized an all-phenylene bismacrocycle (bis- means two) with Siamese-twin structure and used fullerene as guest molecules to assemble a peanut-shaped supramolecular complex. This study was published in
Angewandte Chemie.
As a new type of carbon material, carbon nanotubes (CNTs) have attracted widespread attention because of their outstanding mechanical and photophysical properties. However, the synthesis of CNTs or CNTs fragments with selective simple structure is still a challenge.
The ways in which we approach games reveal much about the inner working of our mind and serve a testbed for researching artificial intelligence and computing algorithms. In a recent study, scientists at JAIST applied novel search indicators in search tree algorithms and used them for solving turn-based games such as Checkers and Connect 4, while also exploring the relationship with subjective playing experiences. Their results help bridge the notions of computing and game playing.

Carbon is vital to the existence of all living organisms, since it forms the basis of all organic molecules that, in turn, form the basis of all living beings. While that alone is pretty impressive, it has recently found surprisingly novel applications in disciplines such as aerospace and civil engineering with the development of carbon fibers that are stronger, stiffer, and lighter than steel. Consequently, carbon fibers have taken over steel in high-performance products like aircrafts, racecars, and sports equipment.
Columbia Engineering researchers have developed SeKVM, the first system that guarantees through a mathematical proof the security of virtual machines in the cloud. This is the first time that a real-world multiprocessor software system has been shown to be mathematically correct and secure, said Computer Science Professor Jason Nieh. This means that users data are correctly managed by software running in the cloud and are safe from security bugs and hackers.
