“…This phenomenon occurred because the water in the atmosphere was decomposed into OH radicals by APPJ and then attached to the SWCNT surface to form hydroxyl groups. [ 38,39 ] Therefore, the formation of hydroxyl groups on the SWCNT surface led to hydrophilicity of the SWCNT films, as shown in Figure 2b. The similar phenomena were observed when fabric was subjected to APPJ treatment.…”

Water‐floating carbon nanotube thermoelectric generators (CNT‐TEGs) can effectively power Internet of Things (IoT) applications. CNT‐TEGs produce electricity by floating on water to generate a temperature gradient in the CNT films, where water pumping via capillary action causes evaporation‐induced cooling in selected areas. However, the amount of electricity required for target applications needs to be increased. Therefore, the wettability of CNT films is controlled via various treatments to increase water evaporation and temperature difference in the films. The contact angle of the water droplet on the film surface related to the wettability decreases upon atmospheric‐pressure plasma jet irradiation and increases upon waterproof spray treatment. Intermediate wettability is obtained by combining the two aforementioned treatments. Under the environmental conditions of light irradiation (1 kW m−2) and wind (3 m s−1) at a water temperature of 20 °C, the CNT‐TEGs with the combined treatment exhibit a highest output voltage of 3.9 mV, which is 30% larger than that of the pristine CNT‐TEG. At a water temperature of 60 °C, a highest output voltage of 13.1 mV is achieved in the pristine CNT‐TEG. The performance enhancement of CNT‐TEGs by controlling the wettability of CNT films under various environmental conditions can facilitate advancements in IoT technology.

Aqueous zinc‐ion batteries (ZIBs) are limited in energy storage by the persistent Zn dendrites, which is a major bottleneck preventing the commercial application of rechargeable aqueous zinc‐ion batteries. The dendritic problems associated with Zn metal anodes can lead to rapid performance degradation, failure and even safety risks of the battery. Zincophilicity of the electrode/electrolyte interface is critical to the stable and safe operation for aqueous ZIBs. In this review, we discuss that zincophilicity can be regulated by tuning the chemical interactions of material surface energy with zinc metal, emphasizing the importance of zincophilic design for improving the electrochemical performance of zinc electrodes. Advances in optimization strategies for the zincophilic zinc metal anode/electrolyte interface are summarized. Challenges and prospects for further exploration and balance of zincophilicity of the anode/electrolyte interface are presented, which are expected to promote in‐depth research and practical applications of advanced aqueous zinc ions.

Carbon exhibits complex behavior due to several allotropes. Processing carbon precursors by different techniques and methods results in various carbon materials. However, the characterizations and analyses of processed carbon materials in any form do not keep up to the mark discussions. There are many uncertainties. First, there is a need to study each carbon allotropic form separately and then the binding of same-state atoms. Depending on the processing conditions of a carbon precursor, the state of the carbon atom changes. The conversion of the carbon atom from one state to another is due to the electron transfer mechanism. The bits of energy with shape-like dashes transfer electrons to nearby unfilled states during the state conversion of a carbon atom. The involved dash-shaped energy bit maintains partially conserved behavior. Atoms in the graphite state also study a one-dimensional structure under the execution of electron dynamics. There is a two-dimensional structure in nanotube atoms and a four-dimensional structure in fullerene atoms. If the diamond atoms bind, the outer ring electrons of the depositing diamond atom undertake an additional clamp of the outer ring energy knot of the deposited diamond atom. Binding in the diamond atoms occurs from the surface (east-west) to the south. Therefore, the growth of the diamond structure occurs from the south to the surface (east-west). Golf-stick-shaped energy bits bind the diamond, lonsdaleite, or graphene state atoms into their structures. In a glassy carbon structure, the layers of gaseous, graphitic, and lonsdaleite atoms bind simultaneously. The layers repeat in order during the growth process of glassy carbon. The hardness of the processed material in each state of carbon provides new insight. This study aimed to understand the fundamental and applied science of carbon atoms and their binding to structures.
