With the recent development of color concentrates for use
with PHBV bioplastics, Teknor Color Co.
now provides fully bio-based
colorants for the four most widely processed bio- and petrochemical-based
biodegradable resins, the company announced today.
Each of the concentrate series is now in commercial use, is
classified as a bio-based material in accordance with ASTM D6866, and meets
ASTM D6400 requirements for composting in an aerobic facility.
The Teknor Color bio-based product range includes
concentrates with four different carrier polymers that are compatible,
respectively, with these four biodegradable resin families:
PHBV. The newest series of color concentrates developed
by Teknor Color Company were formulated for this subclass of the
polyhydroxyalkanoate (PHA) bioplastic family. PHBV is polyhydroxyl butyrate /
PHB. In 2009, Teknor Color collaborated with Telles to develop
color concentrates for use with that company's MirelTM PHB (polyhydroxyl
butyrate) bioplastics, part of the PHA class.
Teknor Color introduced concentrates for use with polylactic acid bioplastics
in 2008 and has since supplied colorants for a wide range of PLA applications.
PBAT. For use with this petrochemical-based biodegradable
copolyester, Teknor Color now offers concentrates with either bio-based or
petrochemical-based carrier resins.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
Using Siemens NX software, a team of engineering students from the University of Michigan built an electric vehicle and raced in the 2013 Bridgestone World Solar Challenge. One of those students blogged for Design News throughout the race.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
