Isoamyl acetate has a banana flavor that can be considered a “natural” ingredient when synthesized using a lipase-catalyzed reaction. Production of isoamyl acetate was up to 10-fold higher with free lipase versus immobilized Candida antarctica li

Lipase-catalyzed synthesis of isoamyl acetate in hexane at 10–250 MPa at 80°C and 1–100 MPa at 40°C resulted in activation volumes of −12.9 ± 1.7 and −21.6 ± 2.9 cm3 mol−1, respectively. Increasing pressure from 10 to 200 MPa resulted i

While most current applications of high pressure (HP) are for inactivating deleterious enzymes, there is evidence that high pressure can induce stabilization and activation of some enzymes. Various other strategies have been employed to enhance enzym

Lipases are important to high value product synthesis, modification, and enhancement. However, they are often unstable above 40 °C. While most current applications of high hydrostatic pressure (HHP) are for inactivating deleterious enzymes, there is

Wheat germ oil (WGO) is a specialty product with a very high nutritional value. The chemical composition of both commercial and pilot scale supercritical carbon dioxide (SC-CO2) processed WGO was examined. This study showed that methods used for oil

Polycrystalline Au films with thicknesses between 30 nm and 80 nm were stepwise implanted with Fe+ ions at liquid helium temperature up to a concentration of 130 ppm and the resulting Kondo behavior was determined in situ down to 1.4 K applying an ac

The critical current density j c of YBa 2 Cu 3 O 7− δ (YBCO) nanobridges (width ≈200 nm) is measured as a function of the magnetic flux density B , applied perpendicular to the YBCO-film plane. The resulting j c -vs- B characteristics, when anal

ZrO2 films prepared at ambient temperature (RT) by ion beam induced chemical vapor deposition onto Si substrates and subsequently annealed at 1300 K in order to obtain their equilibrium monoclinic structure, were bombarded at RT with Ar+ ions of eith
