Effect of L-isoleucine and L-phenylalanine Addition on Aroma Compound Formation During Longan Juice Fermentation by a Co-culture of Saccharomyces cerevisiae and Williopsis saturnus

Some amino acids are known to be precursors of aroma-active compounds produced by yeast metabolism. Thisstudy examined the effect of the addition of L-isoleucine and L-phenylalanine on the volatile profiles of longan winefermented by a co-culture of Saccharomyces cerevisiae var. bayanus EC-1118 and Williopsis saturnus var. saturnusCBS254 inoculated at a ratio of 1:1 000 cfu/mL with the aim of enhancing longan wine aroma. Significantly higherconcentrations of active amyl alcohol (2-methyl-1-butanol), 2-phenylethyl alcohol and their corresponding acetateesters were found in the longan wine with added L-isoleucine and L-phenylalanine respectively, compared with thecontrol (without added amino acids). The biosynthesis of other volatile compounds was either similar or minimallydifferent, although the formation of some acetate esters, such as isoamyl acetate, hexyl acetate and ethyl acetate,was decreased. These results suggest that the added amino acids play an important role in enhancing the productionof targeted aroma compounds in longan wine fermented with mixed yeasts, and that the addition of selected aminoacids can be a valuable tool to modulate the formation of aroma compounds in longan wine

Robustness of large‐area suspended graphene under interaction with intense laser

Graphene is known as an atomically thin, transparent, highly electrically and thermally conductive, light‐weight, and the strongest 2D material. We investigate disruptive application of graphene asa target of laser‐driven ion acceleration. We develop large‐area suspended graphene (LSG) and by transferring graphene layer by layer we control the thickness with precision down to a single atomic layer. Direct irradiations of the LSG targets generate MeV protons and carbons from sub‐relativistic to relativistic laser intensities from low contrast to high contrast conditions without plasma mirror, evidently showing the durability of graphene

Achieving junction stability in heavily doped epitaxial Si:P

Producción CientíficaJunction stability and donor deactivation in silicon at high doping limit has been a long-standing issue in advanced semiconductor devices. Recently, heavily doped epitaxial Si:P layer with phosphorus concentrations as high as 3 × 1021 at./cm3 has been employed in nanowire field-effect transistor (FET) devices for sub-3 nm technology node as low resistance source-drain and channel stressor. In such highly doped Si:P, the actual dopant activation is much less than nominal phosphorus concentration due to inactive phosphorus atoms arising from dopant-vacancy defects (PnV) clustering phenomenon. Even with state-of-the-art high temperature millisecond annealing, this epitaxial film is thermally unstable upon subsequent thermal treatments. To overcome this limitation, we demonstrate a selective dopant activation scheme which results from the dipole moments of inactive PnV structures within the crystal lattice and their direct energy coupling with the external electric field. It's found that superior stability in dopant activation can be achieved through microwave annealing when a specific temperature and field conditions are met using a triple-parallel-susceptor setup in the microwave cavity. Based on experimental results and ab-initio calculation, we proposed a model, whereas the microwave-PnV interactions result in a specific distribution of dopant defect dominated by thermally stable P4V clusters through elimination of unstable low order PnV, leading to the suppression of donor deactivation and achieving thermally stable junction.Ministerio de Ciencia, Innovación y Universidades (Project MOST-109-2628-M-008-004-MY3

Relativistic ion acceleration with nanostructure targets supported by large-area suspended graphene

We discuss the relativistic ion acceleration by irradiating a nanostructure target with ultra- intense laser. The nanostructure target is mounted on a large-area suspended graphene (LSG), which is a novel solid target with remarkable features such as the thinnest, lightest, strongest, transparent, and reasonable, for laser ion acceleration. We have developed various types of targets such as nanometer thin gold, and other materials on LSG, and now carbon nanotube on LSG. This will enable us to access the unexplored regime, relativistic ions.日本物理学会 2020年秋季大

Development of relativistic ion detector for laser-driven ion acceleration

Recent theoretical and numerical studies on laser-driven ion acceleration shows sub- relativistic ion acceleration with multistep acceleration schemes. The multistep acceleration with multiple laser pulses and multiple targets allow us to access the relativistic ion regime with the current and the future laser facilities. However, there is no relativistic ion detectors available in the field of laser ion acceleration. We have been developing energetic ion diagnostics using a combination of solid state nuclear path tracker and Thomson parabola, and scintillator base relativistic ion detectors commonly used in nuclear physics. We introduce our recent progress on the laser driven ion acceleration and the novel diagnostics.日本物理学会2021年秋季大
