With the rapid development of portable electronics, such as e-paper and other flexible devices, practical power sources with ultrathin geometries become an important prerequisite, in which supercapacitors in-plane configurations are recently emerging a favorable competitive candidate. As is known, electrode materials two-dimensional (2D) permeable channels, high-conductivity structural scaffolds, high specific surface areas indispensible requirements for superior performance, while it...
Utilizing a thin film of VS2 ultrathin nanosheets with giant and fast moisture responsiveness, brand-new model moisture-based positioning interface is put forward here, by which not only the 2D position information finger tips can be acquired, but also relative height detected as third dimensionality, representing promising platform for advanced man-machine interactive systems. Detailed facts importance to specialist readers are published ”Supporting Information”. Such documents...
As a conceptually new class of two-dimensional (2D) materials, the ultrathin nanosheets as inorganic graphene analogues (IGAs) play an increasingly vital role in new-generation electronics. However, relatively low electrical conductivity current stage significantly hampered their conducting electrode applications constructing nanodevices. We developed unprecedentedly high nanosheets. The hydric titanium disulfide (HTS) nanosheets, IGAs, exhibit exclusively 6.76 × 10(4) S/m at room...
Carbon monoxide (CO) is a highly poisonous gas, which can cause serious health risk. CO monitoring helps protect us from excessive exposure at home and in the workplace, reduce occupation-related risks for workers. Conventional electrochemical metal oxide semiconductors (MOS) based sensors have been widely used, but drawbacks such as poor selectivity calibration burden also limit their applications, e.g., wearable monitors. Aiming reliable, miniaturized, easy-to-use personal device...
Colorimetry detects a color change resulted from chemical reaction or molecular binding. Despite its widespread use in sensing, continuous monitoring of analytes with colorimetry is difficult, especially when the color-producing binding irreversible. Here, we report on gradient-based colorimetric sensor (GCS) to overcome this limitation. Lateral transport across surface creates gradient that shifts along direction over time, and GCS tracks shift converts it into analyte concentration real...
Due to their high sensitivity and selectivity, low cost, good compatibility for sensor array integration, colorimetric gas sensors are widely used in hazardous detection, food freshness assessment, gaseous biomarker identification. However, usually designed one-time discrete measurement because the sensing materials entirely exposed analytes during process. The fast consumption of limits sensors' applications continuous monitoring, increases operation complexity brings challenges...
Flexible electronics has been an intensively pursued hot topic in recent years, and flexible nonvolatile memory devices (NVMs) are also important concept modern due to the advantages of retaining stored information even when not powered, with great portability high deformability. In this study, we report that δ-K0.5V2O5 bronze sandwiched potassium atoms V–O framework found be a new promising material platform for intriguing applications. The structure alkali metal between two V2O5 layers...
Colorimetry is a popular gas-sensing platform, but it typically limited to one-time use only. Here, we introduce light-controlled configurable colorimetric sensing array overcome this limitation. It features photoactivated reaction between an analyte and material, such that of element can be turned on off with light. By sequential turning each element, the sensor used multiple times as determined by number elements. This analogous data storage device, which lasts until every up. The total...
Colorimetry is widely used in chemical sensing due to its high sensitivity and selectivity. However, most colorimetric sensors are one-time use because the color-producing reactions or bindings usually irreversible. In addition, traditional like detection tubes bulky packed individually, making parallel of multiple analytes difficult. Here, we demonstrate a gradient-based array sensor (GCAS) overcome these limitations. Different elements inkjet-printed as straight lines on porous substrate....
C. Wu, Y. Xie, and co-workers have created ultrathin nanosheets which act as novel interfaces by sensing the 2D position information of fingertips approaching their surfaces, without any need for physical contact. On page 1969, they describe how these are highly moisture-sensitive respond very quickly, giving both relative height in real time. Such a touch-free interface could enable advanced, flexible interactive systems.
