For the evaluation of the mercury concentration of the content of a herbarium box at different ventilation rates a small emission chamber was used.
For the last seven years, Frohnmayer has been an entrepreneurial Jason, searching for a vehicular version of the Golden Fleece: a small, emission-less, front-wheel drive vehicle that's unlike anything else on the market.
In the corresponding limit of small emission wavenumbers, this function can be derived by using either a quantum theory by Lindhard [31] or the classical Boltzmann transport equation [32] (see derivations in [20]).
The variety of status along the supply chain of these sectors led to the difference of attributions between the production and consumption sides, like China, but with a very small emission amount, even if comparing with other countries.
However, obtaining room-temperature erbium luminescence from doped silicon is not easy, mainly because of the low solubility of erbium in bulk silicon, small emission cross section, and very strong non-radiative coupling between erbium ions and the silicon host.
Their employment is however currently limited by their small emission quantum yield (QY) due to non-radiative deactivation of near infrared (NIR) transitions through electronic-vibrational energy transfer (ET).
In Fig. 3a, we note that there is a small emission at 614 nm from the 0 mol% Eu3+ sample (i.e. ZnO-nc SiO2 ZnO-nc SiO2ealed at 450 °C; thisampleue to the broannealedature of the ZnO-nc emission at this annealing temperature.
The environmental chamber method is used to determine the area specific emission factor of VOCs emitted from building products, which is calculated from the small emission test chamber concentration by considering the passing air flow rate and surface area at 23 28 °C.
A small emission of a highly toxic pollutant may be a higher priority than a large emission of a relatively benign pollutant.
