This research proposes a framework to explore green consumption behavior from the perspective of the anxiety of death and individual social responsibility. Research data are collected from a sample of 280 consumers in Taipei, Taiwan. The findings reveal that consumers' anxiety of death affects consumers' green purchase attitude and then ultimately green purchase intention through the mediating variables of environmental concern and pro‐environmental behavior. On a similar line, individual social responsibility is found to act as a precursor in increasing consumer's concern for the environment and, eventually, green purchase attitude and intention. Mastery is found to invigorate the effect of death anxiety on green concern and pro‐environmental behavior, while it enervates the relationship between individual social responsibility and environmental concern.

A photoresponse can be classified based on the mechanism of generation of electrical signals from photons interaction as photovoltaic effect, photoconductive effect, photogating effect, photo thermoelectric effect, bolometric effect and...

On-chip microscopic energy systems have revolutionized device design for miniaturized energy storage systems. Many atomically thin materials have provided a unique opportunity to develop highly efficient small-scale devices. We report an ultramicro-electrochemical capacitor with two-dimensional (2D) molybdenum disulphide (MoS 2 ) and graphenebased electrodes. Due to the tunable density of states, 2D MoS 2 provides electric field-induced doping and, combined with a graphene interface, leads to a high carrier mobility. The fabricated solid-state energy storage device is obtained using a gel electrolyte that provides an electrochemical capacitance of 1.8 mF/cm 2 . An extraordinary enhancement of ∼3000% in electrochemical capacitance (55 mF/cm 2 from 1.8 mF/cm 2 , measured from a cyclic voltammetry curve) is observed upon application of back-gate field of −25 V, which is more than the enhancement (18%) observed in a MoS 2 electrochemical capacitor (0.95 mF/cm 2 from 0.8 mF/cm 2 ) without graphene, whereas the galvanic charge−discharge measurements analysis shows ∼1677% enhancement under the application of −25 V back-gate voltage. Thus, the electric field-induced doping in 2D MoS 2 , in addition to a high charge carrier mobility due to the graphene, plays a crucial role in an extraordinary large energy storage in the ultramicro-electrochemical capacitor. We also evaluated the capacitance response using an AC signal superimposed with the DC bias to investigate the influence of polarization potential on the electrolyte. The study provides a benchmark development of an ultramicro-electrochemical capacitor for ultrahigh charge storage capability.

Background: The platelet-rich fibrin (PRF) has proven an immense role in angiogenesis and epithelization in a wound healing process. The present study aims to ascertain PRF's beneficial role in wound healing after depigmentation surgery. Materials and Methods: A total of 12 systemically healthy controls included were divided into two groups after scalpel depigmentation procedure. PRF was prepared according to Choukroun's standard protocol. Using split-mouth design after depigmentation, one group received PRF membrane, and in second group non-eugenol periodontal dressing was placed. The participants were evaluated for visual analog scale (VAS), healing index (HI) on 3 rd and 5 th day. Epithelization test using toluidine blue and histological examination employing punch biopsy was done on the 5 th day. Results: On statistical scale, VAS, HI, epithelization test, and histological findings were statistically significant in the two study groups. PRF group proved better epithelization test and inflammatory cell infiltration was less in PRF group which confirmed superior wound healing in the group. Conclusion: PRF membrane postdepigmentation provided satisfactory patient comfort and enhanced the wound healing cascade.
