Advanced Functional Materials, EarlyView.A triplet‐blocking layer controls triplet exciton dynamics in blue upconversion OLEDs. The layer keeps charge transfer (CT)‐generated triplet excitons inside the triplet‐triplet annihilation (TTA) host, suppresses anode‐side interfacial quenching, and increases the steady‐state triplet population.

A Low-Voltage Low-Temperature-Coefficient CMOS Bandgap Voltage Reference Generator
, 2007 電壓源在現今的積體電路中扮演著相當重要的角色，參考電壓的應用範圍非常廣泛，最常用於類比-數位轉換器或數位類比轉換器，另外一般常見的電源管理系統、運算放大器或線性穩壓器裡面，都可以見到參考電壓的蹤影，來提供設定輸入或輸出電壓範圍、輸入差動對之電流偏壓源或作為比較器之參考電壓。而能階差參考電壓可以產生一個穩定的電壓源，不因電源電壓與環境溫度的變化而產生變動，以提供系統作為比較或維持電路正常運作之用途，進而提升系統的整體效能。 本論文主要目的為提供一個1.8伏至3.3伏輸入電壓，而輸出電壓在1 ...

Advanced Functional Materials, EarlyView.Atomically dispersed Ni–S4 sites on CdS nanorods induce interfacial charge polarization, directing photogenerated electrons to H2 evolution and holes to selective ester‐bond cleavage of poly(lactic acid). Without sacrificial reagents, this charge‐coupled system produces lactate while suppressing overoxidation, achieving an H2 evolution rate of 41.74 ...
