After establishing themselves as promising active materials in the field of solar cells, halide perovskites are currently being explored for fabrication of low‐cost, easily processable, and highly efficient light‐emitting diodes (LEDs). Despite this, the highest efficiencies reported for perovskite‐based LEDs (PeLEDs) are achieved through spin coating or vacuum evaporation deposition techniques, which...
An unusual spectrally reproducible near‐IR random lasing (RL) with no fluctuation of lasing peak wavelength is disclosed in polycrystalline films of formamidinium tin triiodide perovskite, which have been chemically stabilized against Sn2+ to Sn4+ oxidation. Remarkably, a quality Q‐factor as high as ≈104 with an amplified spontaneous emission (ASE) threshold as low as 2 µJ cm−2 (both at 20 K) are...
BackgroundWe hypothesized that robotic assistance (RARS) could provide better intraoperative and short‐term outcomes than a traditional laparoscopic approach (LARS) to rectal cancer surgery.
MethodsSystematic review of the literature, including electronic searches and communications to international robotic meetings. Inclusion criteria: studies involving rectal cancer patients and comparing outcomes...
