Photochemical aerosol formation from pinene and pinene
Aerosol formation from ot-pinene and •-pinene was studied in a series of outdoor smog chamber experiments. Since a previous tudy focused on •-pinene (Pandis et al., 1991), more attention was given here to ot-pinene. The initial hydrocarbon and NO x concentrations ranged from 37 to 582 ppb and 31 to 380 ppb, respectively. The aerosol carbon yield, the fraction of the carbon initially present tha...
متن کاملPolarized Electron Source Development in Japan
We have continued the basic research to develop the photocathodes for the polarized electron source and to construct the guns for the high energy accelerator , such as e + e ? linear colliders. Four subjects, (1) photocathode development of strained layer superlattice, (2) photoluminescence study of spin relaxation inside the cathode, (3) study of eld emission dark current, and (4) gun design a...
متن کاملBiological activities of α-pinene and β-pinene enantiomers.
The antimicrobial activities of the isomers and enantiomers of pinene were evaluated against bacterial and fungal cells. The agar diffusion test showed that only the positive enantiomers of the α- and β-isomers of pinene were active. The minimal inhibitory concentration (MIC) and minimal microbicidal concentration (MMC) of these monoterpenes were also determined, confirming that the positive en...
متن کاملMicrobial synthesis of pinene.
The volumetric heating values of today's biofuels are too low to power energy-intensive aircraft, rockets, and missiles. Recently, pinene dimers were shown to have a volumetric heating value similar to that of the tactical fuel JP-10. To provide a sustainable source of pinene, we engineered Escherichia coli for pinene production. We combinatorially expressed three pinene synthases (PS) and thre...
