Toyota-led consortium reaches > 50 % net maximum thermal efficiency in both gasoline and diesel cars

A Japanese R&D consortium under the Japanese Agency of Science Technology and led by Toyota estimates that even in 2040, in spite of the advance of electric vehicles, internal combustion engines will be installed in about 89% of the world’s total cars, including hybrid vehicles and plug-in hybrid vehicles. Thus, the optimization of thermal efficiency of combustion motors remains an important target. Thermal efficiency was 30% in the 1970s and reached 40% over the last 40 years. The consortium has succeeded to improve thermal efficiency to over 50 % within just 5 years by the following measures: achieving high-speed spark combustion for gasoline engines, and super lean combustion (super lean burn) for diesel engines. In addition, technology was developed for reducing mechanical friction loss, technology for improving the efficiency of turbocharging systems, and technology for improving the efficiency of thermoelectric conversion systems by R&D for loss reduction common to both engines. As a result of integrating these technologies, the consortium now claims the highest net thermal efficiency of 51.5% for gasoline engines and 50.1% for diesel engines.

Raman-based FACS and microfluidics allow for label-free sorting of over 1,000 microbial cells per second, application to astaxanthin production

The group of Kotaro HIRAMATSU at the University of Tokyo has combined Raman-based FACS with high-throughput microfluidics. In order to accelerate Raman spectroscopy, Fast Fourier Transform Coherent Anti-Stokes Raman Scattering Spectroscopy (Fast FT-CARS Method) was used which allows to measure about 24,000 broadband Raman spectra per second. If applied to nitrogen-depleted Hematococcus strains, the production of astaxanthin could be measured over time at the single cell level.

Solar Frontier Co. exceeds 23 % energy conversion efficiency with CIS-based thin-film solar cells

CIS type thin-film solar cells which use copper (Cu), indium (In), selenium (Se) as a light absorbing layer are thinner than crystalline silicon type solar cells. Under a NEDO contract, the company prepared cells of about 1 cm2from this material, not containing cadmium, and reached 23.235 % energy conversion efficiency. Ongoing work on scaling this technology is considered a great step forward toward reducing the power generation costs of solar cells that combine the high performance and high reliability.

Both JAL and ANA announce to use biojet fuel on flights from San Francisco to Haneda

JAL’s biofuel is supplied by Showa Shell Sekiyu. For 2020, the company announced a charter flight with domestic biojet fuel made from clothing as a raw material. The fuel will be prepared from old cotton clothes collected throughout Japan through the Green Earth Institute Co. in Tokyo via an isobutanol route. ANA’s biojet fuel was manufactured by World Energy Co. from used edible oil from Los Angeles suburbs and also purchased from Showa Shell Sekiyu.

Team at Tokyo Institute of Technology improves synthesis of 2,5-furandicarboxylic aid (FDCA) using ß-manganese dioxide nanoparticles

FDCA is a promising raw material for the synthesis of polyethylene furanoate (PEF), a substitute of PET. It can be prepared by oxidation of glucose-derived 5-hydroxymethylfurfural using a Mn catalyst. The group of Michikazu Hara at TIT has developed an amorphous ß-MnO2 catalyst with a large surface area (nanoparticles) which showed a 3fold higher activity compared to MnO2 catalysts used earlier.

Euglena Corp. finds sulfur metabolites detrimental for biofuel production efficiency

A team of Euglena, RIKEN and tdhe University of Tsukuba have found that Euglena microalgae produce H2S as degradation products of proteins and glutathione. As the smell of sulfur compounds is detrimental both to the food and fuel use of these algae, the company will now look for technologies to supress these degradation processes.

Just 11 types of HLA types prevail in the Japanese, as shown by genome sequencing and machine learning

A research consortium around OKADA Akemi used next-generation sequencing technology and machine learning to analyze white blood cells of 1120 Japanese for their HLA pattern. It came out that only 11 patterns of white blood cells prevail in the Japanese population. Matching with blood type patterns of 170,000 Japanese documented in BioBank and their leukocyte-related diseases such as immune and lifestyle diseases and malignant tumors,  individual differences in HLA patterns were related to more than 50 phenotypes.
