Metallic phase WSe2 nanoscrolls for the hydrogen evolution reaction

“…2c and d), corresponding to the (100) and (002) crystal planes of metallic WSe 2 , respectively. 38,39 The EDX spectrum of the M-WSe 2 nanoscrolls indicates that the prepared M-WSe 2 nanoscrolls are composed of W and Se elements (Fig. S7, ESI †), confirming that the compositions of the samples are WSe 2 based materials.…”

Dimensional engineering of anode materials for high performance potassium ion hybrid capacitor—A review

“…Heterostructures are formed by the close contact of two materials of different conduction types and are widely used in PIHC anode materials 120‐122 . Because atoms of different elements have different outermost electrons, when the electron clouds of two kinds of atoms overlap, lone pairs or holes are created, changing the electrical properties of the material itself.…”

Flexible High‐Stability Self‐Variable‐Voltage Monolithic Integrated System Achieved by High‐Brightness LED for Information Transmission

“…[12][13][14][15] In the last couple years, flexible and wearable power electronic equipment has been continuously developed, and in consideration of ensuring the safety of the device, its indispensable energy storage devices have been proposed need to meet the requirements of low energy consumption, long device life and mechanical robustness. [16][17][18] As a new type of energy storage device, micro-supercapacitor (MSC) possess not only higher safety but also the advantages of high-power density, fast charging rate, and long cycle life. However, the current application of supercapacitors is only corresponding to single function of energy storage, such as electromagnetic shielding, [17] gas detection, [19] motion detection, [20] and other application, [21][22][23][24] and its huge potential device application has not been fully utilized.…”
