(Phys.org) —A team of chemists in Switzerland has developed a new way to protect cash inside of ATM machines from thieves—by automatically setting off a nasty chemical reaction if the machine is molested. The group has ...
(Phys.org) —A large team of researchers, most of which are based in Korea, has succeeded in extending the process of galvanic replacement reactions to ionic compounds. In their paper published in the journal Science, the ...
(Phys.org)—Materials called transition metal oxides have physicists intrigued by their potentially useful properties—from magnetoresistance (the reason a hard drive can write memory) to superconductivity.
