The latest issue of the crystallography magazine is now online - X-Factors Issue 19 (X-Factors, Resonants, and Spectral Lines have now been superseded and augmented by David Bradley's spectroscopynow.com column, which covers all forms of spectroscopy, chemical informatics, and X-ray techniques - reporting on pertinent science news in all those areas.
Titania
is the modern technologists' material of choice, it has found applications in
solar energy conversion, photocatalysis, gas sensing, and even in self-cleaning
windows. One novel use might be in its use as a host material, an intercalator,
for lithium, and researchers are investigating its application as the anode
material in high-power rechargeable lithium-ion batteries or so-called super
capacitors. Now, a UK team has developed nanotubular structures based on an
unusual TiO2 -boron composite that can intercalate lithium more
effectively than titania alone, as revealed by powder diffraction studies.
A
new crystalline form of nickel discovered by Chinese, Italian and US scientists
could provide a new route to metallic materials with novel properties that
sidesteps the need to make entirely new composites or alloys.
X-ray
diffraction could lead to a much more satisfying experience next time you settle
down with a bucket of popcorn. The technique is providing new insights into why
some popcorn kernels pop and why others are dysfunctional.
