emissions and companies subsequently have to pay for the amount of carbon dioxide that they produce. this in effect means that the more wasteful a company is in terms of its carbon dioxide output, the more they stand to lose financially. the government also sets a cap on the total amount of carbon dioxide...
a secure backup source of electricity for your home. an inverter, which converts dc electricity to alternating current (ac) electricity, is required to power almost all electricity uses in the home. the basic photovoltaic cell typically produces only a small amount of power. to produce more power, cells...
been developed recently for converting epoxyethane to ethane- -diol with a yield of well over %. it is based on technology from mitsubishi chemicals and further developed by shell chemicals. the conversion from epoxyethane to the diol takes place in two stages. first the epoxide reacts with carbon dioxide...
