To prolong the storage period of fresh Lilium longiflorum, maintain its quality during storage, and optimise controlled atmosphere (CA) parameters. In a single-factor experiment, temperature, humidity, O2 CO2 concentrations were considered as primary factors affecting CA L. longiflorum. Then, comprehensive score was optimised using back propagation neural network combined with empirical data. F...

We discuss our experimental progress toward energyefficient electrochemical CO2 capture from the atmosphere. First we discuss the latest results from an ongoing project that uses a modified-fuel-cell-based approach for CO2 concentration [1]. Using this approach, we have demonstrated CO2 capture from atmospheric concentrations with an energy consumption of less than 400 kJ/mol(CO2). We also disc...

In their pioneering work, Leighton and Murray argued that the Mars atmosphere, which at present is 95% carbon dioxide, is controlled by vapor equilibrium with a much larger polar reservoir of solid carbon dioxide. Here we argue that the polar reservoir is small and cannot function as a long-term buffer to the more massive atmosphere. Our work is based on modeling of the circular depressions com...

The humidity present in ambient atmosphere affects the adhesion of small particles by causing capillary bridge formation between the particle and the surface. Even in moderate relative humidities this, usually attractive, force can have a significant effect on adhesion behaviour of micro and sub-micro particles. We have directly measured the pull-off forces of initially adhered oxide particles ...

Gas-phase chemical mechanisms for use in regional or global tropospheric atmospheric chemistry applications require validation against measurement data in order to assure the modeller and policy-makers that the mechanism adequately represents the chemical processes of the real atmosphere. One means of mechanism validation is through the use of smog-chamber data, in which atmospheric chemistry e...

A critical component for predictions of formation of ozone and other secondary pollutant formation in the atmosphere is the chemical mechanism, i.e., the portion of the airshed models used to represent the chemical reactions involved. This is because the chemistry is the source of much of the complexity and non-linearity involved. Because many of the chemical reactions are incompletely understo...

Several extensions of energy balance models (EBMs) are explored in which (i) sea ice acts to insulate the atmosphere from the ocean and (ii) ocean heat transport is allowed to have some meridional structure controlled by the wind, with minima at which the ice edge can rest. These new models support multiple stable ice edges not found in the classical EBM and a hysteresis loop capable of generat...

The quantum bit error rate is a key quantity in quantum communications. If the quantum channel is the atmosphere, the information is usually encoded in the polarization of a photon. A link budget is required, which takes into account the depolarization of the photon after its interaction with the atmosphere as well as absorption, scattering and atmospheric emissions. An experimental setup for t...

The Mars Pathfinder atmospheric structure investigation/meteorology (ASI/MET) experiment measured the vertical density, pressure, and temperature structure of the martian atmosphere from the surface to 160 km, and monitored surface meteorology and climate for 83 sols (1 sol = 1 martian day = 24.7 hours). The atmospheric structure and the weather record are similar to those observed by the Vikin...
