    Abstract Today, nanoscrystals are researched and developed very quickly because of their advantages in many areas of life. One of the potential applications is quantum dot-sensitized solar cells. This is a green, clean, environmentally friendly cell, and has been studied by scientists since 2000. In this study, we fabricated photoanodes with Cu

    Abstract This paper explores the relationship between destination image, cultural contact, perceived risk, satisfaction, and the revisit intention of international tourists to Binh Thuan province in Vietnam based on data obtained from 405 international tourists. Employing Partial Least Squares Structural Equation Modeling (PLS-SEM) techniques, the study delivered two key results. The first finding is that revisit intention is directly affected by satisfaction, attractiveness, accommodation service, cultural contact, and perceived risk. Secondly, satisfaction is directly affected by attractiveness, accommodation service, cultural contact, and perceived risk. These results confirm the moderating role of both nationality and marital status on the relationships from cultural contact and attractiveness to satisfaction, but not revisit intention. However, the research has certain limitations: (i) due to the limited resources available to conduct the research, the sample size was limited to 405 international tourists in Binh Thuan province; and (ii) this study conducted sampling using direct interview methods of tourists during the peak season.

    Abstract In this study, TiO 2 /CdS/Cd x Cu 1−x Se, TiO 2 /CdS/Cd x Mn 1−x Se, and TiO 2 /CdS/Cd x Ag 2−2x Se thin films were synthesized by chemical bath deposition for the fabrication of photoanode in quantum-dot-sensitized solar cells. As a result, the structural properties of the thin films have been studied by X-ray diffraction, which confirmed the zinc Blende structure in the samples. The optical films were researched by their experimental absorption spectra with different doping concentrations. Those results were combined with the Tauc correlation to estimate the absorption density, the band gap energy, valence band and conduction band positions, steepness parameter, and electron–phonon interaction. Furthermore, the electrical features, electrochemical impedance spectrum and photocurrent density curves were carried out. The result was used to explain the enhancing performance efficiency.

    Abstract The evolution of Internet of Things (IoT) networks has been studied owing to the associated benefits in useful applications. Although the evolution is highly helpful, the increasing day-to-day demands of mobile users have led to immense requirements for further performance improvements such as efficient spectrum utilization, massive device connectivity, and high data rates. Fortunately, reconfigurable intelligent surfaces (RIS) and non-orthogonal multiple access (NOMA) techniques have recently been introduced as two possible current-generation emerging technologies with immense potential of addressing the above-mentioned issues. In this paper, we propose the integration of RIS to the existing techniques (i.e., NOMA and relaying) to further enhance the performance for mobile users. We focus on a performance analysis of two-user group by exploiting two main performance metrics including outage probability and ergodic capacity. We provide closed-form expressions for both performance metrics to highlight how NOMA-aided RIS systems provide more benefits compared with the benchmark based on traditional orthogonal multiple access (OMA). Monte-Carlo simulations are performed to validate the correctness of obtained expressions. The simulations show that power allocation factors assigned to two users play a major role in the formation of a performance gap among two users rather than the setting of RIS. In particular, the strong user achieves optimal outage behavior when it is allocated 35% transmit power.

    Abstract Phytochemical study on the EtOAc-soluble extract of the leaves of Mimosa pigra led to the isolation of a new furanochromone, 6,8-dihydroxy-2-methyl-9H-furo[3,2-b]chromen-9-one (1), along with four known compounds (2–5). Their structures were elucidated based on the basis of the spectral interpretation. The plausible biosynthesis pathway for the formation of the new furanochromone was proposed. At a concentration of 100 µM, compound 1 showed no cytotoxicity against human MCF-7 breast cancer cell with a cell viability >50%.

    Abstract From the EtOH-soluble extract of the roots of Piper nigrum, one new dimeric alkamide, pipercyclobutanamide D (1) was isolated. Its structure was elucidated on the basis of NMR spectroscopic interpretation. The relative configuration of 1 was determined based on the NOESY analysis. Compound 1 showed α-glucosidase inhibitory activity with an IC₅₀ value of 158.5 µM. In addition, compound 1 exhibited cytotoxicity against the MCF-7 and HepG2 cell lines with the IC₅₀ values of 45.6 and 63.9 µM, respectively. Plausible biosynthetic pathway for the formation of 1 was proposed based on regioselective [2 + 2] cycloaddition reaction.

  9. Article: What makes consumers willing to pay for carbon taxes–A view of terror management theory

    Abstract The growing exasperating effect of climate change calls for an immensely augmented decline of carbon dioxide (CO₂) emissions in all aspects of human life. Marketers have increasingly employed different strategies in attempt to change consumer behavior having a pivotal role in diminishing CO₂ emissions. Yet, little work has been done to investigate the influencing factors that can develop sustainable consumption patterns. Drawing on Terror Management Theory (TMT), this research attempts to explore the relationships between omnipresent fear of death and consumers’ willingness to pay for carbon emissions. The results demonstrate that mortality salience is positively associated with materialism whereas self-esteem tends to decrease it. The results further indicate that, these two research precursors positively influence consumers’ health consciousness; materialism and health consciousness lower and positively influence consumers’ willingness to pay extra to offset carbon emissions, respectively. This study advances our knowledge regarding the willingness of consumers to pay for carbon offsets and strengthens the literature on climate change response by providing empirical evidence of the effects of various psychological factors. On the basis of these findings, this study also provides key managerial instructions for the carbon offset program. Fear of death is critically important because it can greatly affect consumers’ willingness to pay for carbon taxes, so managers should foster consumers’ self-esteem yet offering material bonuses to airline passengers, on the contrary, might not have a desired effect on sustainable behavior.
