Producing biodegradable plastic just got cheaper, greener
Mon, 06 Jul 2015 11:42:37 EDT
Biodegradable drinking cups or vegetable wrapping foil: the bioplastic known as polylactic acid (PLA) is already a part of our everyday lives. And yet, PLA is not yet considered a full alternative to traditional petroleum-based plastics, as it is costly to produce. Researchers now present a way to make the PLA production process more simple and waste-free.
New lithium ion battery is safer, tougher, and more powerful
Fri, 03 Jul 2015 07:27:49 EDT
Lithium ion batteries are a huge technological advancement from lead acid batteries which have existed since the late 1850's. Thanks to their low weight, high energy density and slower loss of charge when not in use, these have become the preferred choice for consumer electronics. Lithium-ion cells with cobalt cathodes hold twice the energy of a nickel-based battery and four-times that of lead acid. Despite being a superior consumer battery, lithium-ion batteries still have some drawbacks. Current manufacturing technology is reaching the theoretical energy density limit for lithium ion batteries and overheating leading to thermal runaway i.e. "venting with flame" is a serious concern.
'Invisible' protein structure explains the power of enzymes
