Plasmonic photocatalysis has emerged as a prominent and growing field. It enables the efficient use of sunlight as an abundant and renewable energy source to drive a myriad of chemical reactions. For instance, plasmonic photocatalysis in materials comprising TiO2 and plasmonic nanoparticles (NPs) enables effective charge carrier separation and the tuning of optical response to longer wavelength regions...
A key goal in developing molecular microrobots that mimic real‐world animal dynamic behavior is to understand better the self‐continuous progressive motion resulting from collective molecular transformation. This study reports, for the first time, the experimental realization of directional swimming of a microcrystal that exhibits self‐continuous reciprocating motion in a 2D water tank. Although the...
Many materials with nanofluidic channels are exploited to achieve salinity gradient energy conversion. However, most materials are fragile, difficult to process, or only prepared into a limited size, which greatly restricts their practical application in the future. Herein, a covalent organic polymers membrane with high mechanical property and stability is fabricated, which can keep integrity in harsh...
Energy Harvesting
There are salinity gradients at the confluence of the river and sea, which contain tremendous amounts of energy. In article number 2107600, Jin Zhai and co‐workers fabricate a covalent organic polymers membrane for harvesting the salinity gradient energy. The membrane has better properties and can be prepared in large areas, which is expected to be applied in the future to real‐world...
Refrigeration based on the electrocaloric effect can offer many advantages over conventional cooling technologies in terms of efficiency, size, weight, and power source. The discovery of ferroelectric and antiferroelectric properties in fluorite‐based materials in 2011 has led to diverse applications related to memory (e.g., ferroelectric tunnel junctions, nonvolatile memory, and field‐effect transistors)...
To achieve clean and high‐efficiency utilization of renewable energy, functional surfaces with controllable and patternable wettability are becoming a fast‐growing research focus. In this work, a laser scribing strategy to fabricate patterned graphene surfaces that are capable of energy conversion in different forms is demonstrated. Using the laser raster‐scanning and vector‐scanning modes, two distinct...
Owing to their rich surface chemistry, high conductivity, tunable bandgap, and thermal stability, structured 2D transition‐metal carbides, nitrides, and carbonitrides (MXenes) with modulated atomic environments have emerged as efficient electrochemical energy conversion systems in the past decade. Herein, the most recent advances in the engineering of tunable structured MXenes as a powerful new platform...
