  • Photoelectrocatalytic nitrate reduction offers an opportunity for a lower carbon route to ammonia production but has not been realized due to poor efficiency. Here an efficient modified lead halide perovskite photocathode is coupled to glycerol oxidation anode resulting in a bias-free photocurrent density greater than 20 mA cm−2.

  • The efficiency of perovskite quantum dot solar cells based on organic cations is relatively low. Aqoma et al. develop an alkyl ammonium iodide-based ligand exchange strategy for the replacement of the long-chain oleyl ligands and phase stabilization that enables 18.1%-efficiency solar cells.

  • Thermoelectric devices have received significant attention for energy generation owing to their unique advantages over traditional heat engines. Here, the authors developed a well performing stretchable and self-healable iono thermoelectric material by optimizing the thermophoresis of protons in a polymer complex PEDOT:PAAMPSA:PA polymer.

  • Lateral flow assays are valuable rapid diagnostic tests, but low sensitivity can hinder their precision. Here, the authors report an enrichment method using nanoporous AAO and red blood cell membranes, which when applied to patient samples prior to analysis can improve sensitivity up to 20-fold.

  • The thermal conductance of single-molecule junctions is measured using picowatt-resolution calorimetric scanning probes and is found to be nearly independent of the length of the alkanedithiol molecules studied.

  • Multifunctional phase-change hybrid materials containing paraffin waxes (PWs) within a microporous conjugated polymer (CP) film were developed for new sensor and actuator applications. The hybrid films were prepared simply by depositing various PWs onto CP films to show critical changes in FL intensity and color during the phase change of PWs. This fascinating FL response behavior to external heat facilitated various applications such as reversible writing/erasing, fingerprinting and thermometer sensors. An appropriate layer-supported hybrid film showed extremely fast and highly reproducible thermomechanical actuation.
