Electrospinning in controlled nitrogen atmosphere is developed for the realization of active polymer nanofibers. Fibers electrospun under controlled atmospheric conditions are found to be smoother and more uniform than samples realized by conventional electrospinning processes performed in air. In addition, they exhibit peculiar composition, incorporating a greatly reduced oxygen content during...

We applied a time-resolved, optical trapping-Raman spectroscopy (OT-RS) technique to characterize single, trapped bioaerosol particles under well-controlled reactive conditions that mimic the native state of in atmosphere.

We present simulations of atmospheres of Earth-like aquaplanets that are tidally locked to their star, that is, planets whose orbital period is equal to the rotation period about their spin axis, so that one side always faces the star and the other side is always dark. Such simulations are of interest in the study of tidally locked terrestrial exoplanets and as illustrations of how planetary ro...

Modified/controlled atmosphere applications, as an alternative to the chemical treatments, are effective technique in controlling pest of stored products, especially dried fruits. In gas tight units, it is applied with principle preventing insect respiration by changing oxygen (O2), carbon dioxide (CO2) and nitrogen (N2) levels atmosphere. study, 1-, 2- 3- d-old pupae fruit beetle, Carpophilus ...

Laboratory experiments permit quantifying the effects of an atmosphere on cratering efficiency by hypervelocity impacts. Three separable processes have been identified: ambient a mospheric p essure, a rodynamic drag, and pr.•ectile-atmosphere interactions. The effect of ambient atmosphere can be described by a dimensionless pressure ratio, P/By/" for a pressure P, target density 8, and impact v...

During the 1995 season, large (-275g), medium (175g) and small (125g) ’O’Henry’ peaches were stored in either air, 5% CO, + 2% 0, or 17% CO, + 6% 0, at 38°F (3.3”C). Large ‘O’Henry’ peaches benefited more from the 17% CO, + 6% 0, than from either the 5% CO, + 2% 0, or the air storage treatment. During the 1996 season, large, medium and small ‘Elegant Lady’ and ’O’Henry’ peaches were stored in a...

Fresh blueberries are commonly stored and transported by refrigeration in controlled atmospheres to protect shelf life for long periods of storage. Ozone is an antimicrobial gas that can extend shelf life and protect fruit from microbial contamination. Shelf life of fresh highbush blueberries was determined over 10-day storage in isolated cabinets at 4°C or 12°C under different atmosphere condi...
