The rapid and controllable fabrication of large-scale and highly ordered micro-honeycomb arrays induced by nonsolvent phase separation.

Structures that are highly ordered in nature show unique light propagation abilities. Among them, micro-honeycomb arrays are attractive owing to their advantages relating to the collection of light or enlarging the viewing angle and, also, owing to their potential applications in precision optics. Inspired by the natural phenomenon of droplet condensation on a cold surface, breath figure self-assembly has been a common approach used to fabricate such ordered micro-honeycomb arrays.

Highly Efficient Photothermal Conversion of TiCT/Ionic Liquid Gel Pen Ink for Smoothly Writing Ultrasensitive, Wide-Range Detecting, and Flexible Thermal Sensors.

Photothermal conversion behavior has a vital application to disease therapy, water purification, or uncontacted heaters. The fabrication of high-performance photothermal conversion materials especially for near-infrared (NIR) light and microstructures has attracted a great deal of attention. Among numerous substances, MXene as a new type of 2D material with semi-metallic and unique electromagnetic properties presents a broader absorption of light and even a typical plasmonic absorption near the NIR-I area (808 nm), which has made it suitable for photothermal conversion.

Tunable Fabrication of Conductive TiCT MXenes via Inflating a Polyurethane Balloon for Acute Force Sensing.

Conductive microwrinkles present a superior performance in ultrasensitive sensing, smart controlling, as well as energy conservation because of their unique structures. These wrinkles are usually prepared by the deposition of a thin conductive stiff layer on a soft substrate under a certain strain. However, traditional conductive materials may encounter some deficiencies, such as fragility or poor dispersity, in any solvent.
