The power consumption in stand-by mode is smaller than 2 mu W. Common-emitter characteristics show that the sensing base (collector) current gains at 25 degrees C in 0.01%, 0.1%, and 1% H-2/N-2 are as high as 75 (512), 134, (977), and 233 (2.89 x 10(3)), respectively. Low-power consumption and high-sensitive gains are indicative that our HBT together with planar-type MSM sensor is very promising for applications to hydrogen sensing transistors using one voltage source.

Increasing consumption requires an understanding and exploration of important aspects of the consumption process and consumers' behaviour. Sustainable consumption fulfils human needs, increases quality of life, reduces environmental damage and minimizes the risk to human health. A set of qualitative aspects and criteria is selected, validated by experts, using the Delphi method. Qualitative information is translated into comparable scales by applying fuzzy set theory. The interrelationships among the attributes are then identified by using a decision-making trial evaluation in the laboratory. Choquet integral is used to eliminate problems of expert subjectivity and this interactivity method, thus, provides higher insight into effectively addressing uncertainties. The results show that social impact and consumer behavior have a significant role in driving sustainable consumption behavior, representing an individual's motivation in planning or decision making when performing a specific sustainable behavior. Sustainable consumption behavior is motivated by perceived consumer effectiveness, trust from consumers, environmental knowledge, environmental responsibility, behavioral intention, emotion, and motivation regarding social consumption mot. Theoretical and managerial implications are also provided.

This paper focuses on maximizing the network lifetime of barrier coverage in WSN with mobile sensors. For mobile sensors, movement energy consumption can be much higher than during sensing and communication. Since the battery capacity of the sensor is fixed, more energy can be used for sensing and communication if the movement distance required to build the barrier can be reduced. Therefore, we focus on reducing the movement distance required by the mobile sensors to build the barriers. Also, we can build as many barriers as possible if we use as few mobile sensors as possible to build a barrier. By rotating multiple barriers, we can further extend the lifetime of the network. Based on the above concept, an energy-efficient algorithm is proposed for building barriers in WSNs with mobile sensors. The contribution of this paper are: (1) We find the minimum number of sensors required to construct a barrier for a rectangular region. (2) We explain how to cluster the sensors in the region, and then calculate the linear equations of the barriers based on the results of the clustering. (3) We explain how to set the sojourn points for these linear equations of the barriers, and then assign the mobile sensors to every one of these sojourn points. In short, the proposed algorithm can construct multiple barriers depending on the location of the sensor, with a minimum number of sensors connecting the left and right boundaries of the target field. Finally, the simulation results show that the proposed algorithm has better performance in terms of network lifetime than the previous result. (c) 2022 The Author(s). Published by Elsevier B.V.

In this study, a MoO3 nanolayer was applied as a sacrificial layer to optimize the quality of the interface between the CZTSSe and Mo back contact. MoO3 nanolayers can greatly improve CZTSSe grain growth and suppress the formation of some harmful secondary phases, especially the undesirable MoS(e)(2). In terms of device performance, the series resistance was reduced from 1.83 to 1.54 omega center dot cm(2), and the fill factor was significantly enhanced from 42.67% to 52.12%. Additionally, MoO3 nanolayers improved CZTSSe absorber quality by lowering the defect energy levels from 228 to 148 meV. Furthermore, first-principles calculations demonstrate that the partial sulfoselenized MoO3 nanolayers may function as the (p-type) hole-selective contacts at Mo/CZTSSe interfaces, leading to an overall improvement in device performance. Lastly, a CZTSSe solar cell with about 26% improvement (compared with reference cells) in power conversion efficiency was achieved by inserting 5 nm MoO3 sacrificial layers.
