Interband Mid-IR Semiconductor Lasers
IEEE Photonics Journal, 2010 Significant advances in the room-temperature (RT) continuous-wave (CW) output power of both type-I quantum-well (QW) active-layer lasers and interband cascade lasers have been reported within the 3–4- $\mu\hbox{m}$ wavelength region in 2009 ...

OsCPK12‐OsATPD1 Module Regulates Photosynthetic Acclimation to Light Stress in Rice
Advanced Science, EarlyView.OsCPK12 interacts and phosphorylates OsAtpD1 at Ser8 in its transit peptide. This phosphorylation promote its chloroplast translocation, thereby maintaining ATP synthase activity and proton gradient (ΔpH) homeostasis and regulating photosynthetic acclimation, photoprotection, and repair under light stress.

Advanced Science, EarlyView.Corynoxine exerts potent broad‐spectrum anticancer activity by directly targeting NQO1. This interaction dissociates the oncogenic NQO1‐PTPA complex, releasing PTPA to robustly activate the tumor suppressor PP2A. Consequently, downstream Raf/MEK/ERK and PI3K/AKT signaling pathways are suppressed, downregulating c‐Myc and driving tumor regression ...
