Tanzania water source. Credit: Bob Metcalf I don’t have enough historical perspective to know if this is truly a eureka moment or not, but a group from Rice University reports that adding a small amount of silica (or another inexpensive silicon source) can amp up the anti-viral, anti-bacterial power of titanium dioxide for producing disinfected…

Superior heat transfer ability of graphene-on-substrate demonstrated

By / April 15, 2010

Those engineering electronic devices always have had to factor in the use of special materials that can conduct heat away from crucial components. Bulk copper’s thermal conductivity is pretty good at around 400 watts per meter per kelvin, but this ability decreases as the copper approaches film-size dimensions. Diamond has long been known to have…
