It is substantially challenging for non‐centrosymmetric (NCS) Hg‐based chalcogenides for infrared nonlinear optical (IR‐NLO) applications to realize wide band gap (Eg > 3.0 eV) and sufficient phase‐matching (PM) second‐harmonic‐generation intensity (deff > 1.0 × benchmark AgGaS2) simultaneously due to the inherent incompatibility. To address this issue, this work presents a diagonal synergetic...
Inorganic chalcogenides have been studied as the most promising infrared (IR) nonlinear optical (NLO) candidates for the past decades. However, it is proven difficult to discover high‐performance materials that combine the often‐incompatible properties of large energy gap (Eg) and strong second harmonic generation (SHG) response (deff), especially for rare‐earth chalcogenides. Herein, centrosymmetric...
Mitochondria are believed to be the major source of intracellular reactive oxygen species (ROS). However, in situ, real‐time and quantitative monitoring of ROS release from mitochondria that are present in their cytosolic environment remains a great challenge. In this work, a platinized SiC@C nanowire electrode is placed into a single cell for in situ detection of ROS signals from intracellular mitochondria,...
Controllable synthesis of ultrathin metal–organic framework (MOF) nanosheets and rational design of their nano/microstructures in favor of electrochemical catalysis is critical for their renewable energy applications. Herein, an in situ growth method is proposed to prepare the ultrathin NiFe MOF nanosheets with a thickness of 1.5 nm, which are vertically inlaid into a 3D ordered macroporous structure...
With the objective of investigating the acute activation of inflammatory cascades upon exposure to gold nanoparticles (GNPs) as well as detailing the mechanisms, a reporter mouse model that allows for non‐invasive and longitudinal imaging of hepatic acute‐phase serum amyloid A (SAA) activation is constructed. The model is able to visualize SAA activation at the transcriptional stage, with higher sensitivity...
