Such fixtures should not be placed directly on glass tops; temperature differences between external and internal surfaces of the glass may cause it to break. (petbusiness.com)
MOFs, which have a lot of internal surface area to adsorb gases and store them at high density, are one of the most promising materials for adsorbed natural gas (ANG) storage. (sciencedaily.com)
The fRsi value is calculated by dividing the lowest identified internal surface temperature (Ti) by the overall temperature difference across the structure (dT or delta T for temperature difference) under standard conditions. (passivehouseplus.ie)
