Conclusions Charge separation in solutions of liposomes sensitized by MP at low temperatures and apparently also at 20°C takes place according to a mechanism of two-quantum photoionization of dimeric molecules of the metalloporphyrins.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 2, pp. 277–282, February, 1985. 相似文献

Conclusions The formation of OH radicals in the photoreduction of aqueous solutions of anthraquinonesulfonic acid as the result of electron transfer from water (OH–) to a triplet molecule has been demonstrated.Translated from Izvestiya Akademii Nauk, Seriya Khimicheskaya, No. 11, pp. 2615–2617, November, 1969. 相似文献

The chemical industry admits to minimal use of microwave power because of its high capital and operating costs relative to
steam, combustion, electrical, and other traditional sources of energy. Other valid historical and persistent reasons for
their lack of proper use include: a poor conceptual understanding of microwaves by chemical professionals, their unwillingness
to replace existing adequate methods with radically new technology, the infancy of the microwave industrial power supply,
and unfamiliarity of microwave power systems manufacturers with the chemical industry. In years past, the North American chemical
industry had few competitors and profits were generally large. Environmental regulations were few and product quality was
less a concern than production volume. The microwave power industry relied on the government and communications for lucrative
sales. Those days appear over.
Chemical manufacturers must probe every technology to achieve the edge necessary to stay competitive while meeting environmental
stewardship demands. Microwave power has always offered unique advantages in heating materials selectively and/or quickly
to high or preselected temperatures with fast control response. In the cases discussed in this paper, novel applications of
microwave power afford: faster production, a reduction in product contaminants, reduced downtime, reduced waste, product quality
improvements, and better pollution control. 相似文献
