All the indices such as the speed of sensitization, intelligibility, contrast and conservation property of the prepared paper meet the same level of Japanese Ricoh high speed diazo paper SDE. The paper also expounds the exposure, development and image formation principles and methods of diazo sensitive paper and the methods for quality detection.展开更多

In the past few years, they have been researched for various biomedical applications, such as drug/cell carriers, tissue engineering, and biosensors. Particularly, the hy- drogels used as drug delivery systems have shown distinct advantages in phototherapy. This review presents recent advancements of hydrogel＇s use in phototherapeutic applica- tions by focusing on three kinds of phototherapentic methods including photodynamic therapy （PDT）, photothermal therapy （PTT）, and phototherapy-containing combination therapy （PCCT）. The applications of these therapies in anti- cancer and antibacterial fields have also been summarized. We hope that this review will inspire researchers to further develop promising materials for phototherapy applications.展开更多

Benzothiazole was incorporated as an additional acceptor, which greatly enhanced the molar ex- tinction coefficient of the dyes. Various conjugated linkers, such as benzene, furan and thiophene, were also introduced to con- figure the novel D-A-n-A framework in order to prolong electron flow and active transportation. Among all dyes, Z2 contain- ing a thiophene linker exhibited the maximum overall conversion efficiency （r/） of 4.16% （Jsc = 9.27 mA cm-2, Voc = 642 mV, FF = 0.70） under standard global AM 1.5 G solar condition.展开更多
