Taiwan team engineers E. coli to produce n-butanol from glycerol

Green Car Congress

Researchers at Feng Chia University in Taiwan have engineered the bacterium Escherichia coli to produce n-butanol from crude glycerol—a byproduct of the production of biodiesel. The conversion yield and the productivity reached 87% of the theoretical yield and 0.18 g/L n-butanol from 20 g/L crude glycerol. g/L/h, respectively.

Electron sandwich doubles thermoelectric performance

Green Car Congress

Researchers from Hokkaido University and their colleagues in Japan and Taiwan have more than doubled the ability of a material to transform wasted heat into usable electricity by significantly narrowing the space through which spread electrons move, according to a new open-access study published in the journal Nature Communications.

Researchers propose low-temperature SOFC unit for reducing NOx and oxidizing HCs in lean-burn engine exhaust

Green Car Congress

A team from National Tsing Hua University, Taiwan, reports that a low-temperature solid oxide fuel cell (SOFC) emissions control system for lean-burn engines can simultaneously reduce the high concentrations of NO x and oxidize hydrocarbon (HC) emissions. Concept of the SOFC emissions control system. Credit: ACS, Huang et al.

VisIC and ZF partner on R&D effort to develop EV inverter based on GaN semiconductor technology; focus on 400V

Green Car Congress

The inverter—which converts DC power from the traction battery to AC power that drives the motor—is a key part of the electric drive chain. This conversion comes from a complex sequence of switching events which reconstruct an AC signal from the DC output of the battery.

New systems biology model for wood formation can lead to progress in biofuel and green chemistry applications

Green Car Congress

Researchers in the US, China and Taiwan have developed a new systems biology model that mimics the process of wood formation, allowing scientists to predict the effects of switching on and off the 21 (at least) pathway genes involved in producing lignin, a primary component of wood. The model tracks 25 key wood traits.
