Chemists have devised a new way to stabilize highly reactive molecules called carbenes. (p. 392)Published: June 23rd, 2001; Vol.159 #25Found in: Chemistry -
Researchers have discovered how the orientation of amino acid molecules can make a growing crystal take on either a right- or a left-handed form. (p. 373)Published: June 16th, 2001; Vol.159 #24Found in: Materials Science -
New calculations show that a basic tenet of chemistry is wrong: Ethane forms its most stable structure not due to so-called steric effects, but because of a quantum mechanical influence. (p. 340)Published: June 2nd, 2001; Vol.159 #22Found in: Chemistry
