Along with industrialization and rapid urbanization, environmental remediation is globally a perpetual concept to deliver a sustainable environment. Various organic and inorganic wastes from industries and domestic homes are released into water systems. These wastes carry contaminants with detrimental effects on the environment. Consequently, there is an urgent need for an appropriate wastewater treatment technology for the effective decontamination of our water systems. One promising approach is employing nanoparticles of metal oxides as photocatalysts for the degradation of these water pollutants. Transition metal oxides and their composites exhibit excellent photocatalytic activities and along show favorable characteristics like non-toxicity and stability that also make them useful in a wide range of applications. This study discusses some characteristics of metal oxides and briefly outlined their various applications. It focuses on the metal oxides TiO2, ZnO, WO3, CuO, and Cu2O, which are the most common and recognized to be cost-effective, stable, efficient, and most of all, environmentally friendly for a sustainable approach for environmental remediation. Meanwhile, this study highlights the photocatalytic activities of these metal oxides, recent developments, challenges, and modifications made on these metal oxides to overcome their limitations and maximize their performance in the photodegradation of pollutants.
The benefits and advantages of the incorporation of ESG (Environmental, Social, Governing)-related policies have been discussed extensively. However, research articles focus not only on the socioecological aspects of Corporate Social Responsibility (CSR) but also on the underlying effects on a corporation’s corporate financial performance (CFP). In this regard, the current study aims to analyze the impact of ESG parameters on corporations’ financial stability. A sample size of 691 companies in North American countries was investigated in order to test the hypothesis that ESG has an effect on the likelihood of a company going bankrupt using the Ohlson O-score. This is conducted using regression models and the Pearson correlation coefficient. Furthermore, a follow-up hypothesis on the relationship between firm size and ESG is also tested in order to evaluate a tendency of corporate growth through ESG-based sustainable development. The results of the study conclude that the governing pillar of ESG factors has the highest positive impact on corporations’ financial success. Furthermore, the analysis conducted in the study with its sample size confirms the hypothesis that larger firms tend to have higher ESG scores.
The article proposes evaluating the costs of bioenergy supplies in Russia utilizing a method that is based on energy analysis. The main disincentivizing factor is not as much limited resources as the marginal cost of producing biofuels and the possibility of using cost-effective ways of reducing greenhouse gas emissions, including carbon capture and storage, alternative forms of renewable energy, energy efficiency and energy savings. In this situation, the possibility of progressive development of the global market for biofuels can only be achieved by fundamental changes in the industry, that are determined by the peculiarities of scientific progress. The author also identifies several technological, economic, financial and natural factors constraining large-scale advances in bioenergy. Comparing innovation policies of various countries of the world and paper notes of industrialized countries, we can see a high level of R&D investments in the field of biofuel technologies.
The current study aims to examine how students’ intentions to use 4.5G mobile phones are affected by the social-economic factors of performance expectancy, cost, effort expectancy, and social influence. This study is based on the perspectives of the unified theory of acceptance and use of technology (UTAUT). The central assumption of this study is that when students use 4.5G mobile services to source information at university, their academic performance is likely to improve. From eight private and public universities in Malaysia, 2117 students were enrolled in this study. We investigated the effects of gender and awareness as moderators on the relationships among the variables of interest. The findings showed that social influence and performance expectancy positively affected university students’ intentions to use 4.5G mobile phones. The researchers conducted a multigroup analysis to confirm the moderating effect of gender among the underlying relationships in the model. Structural equation modeling analysis indicated that, unlike awareness, gender did not moderate social influence, effort expectancy, performance expectancy, or the cost of students’ intentions to use 4.5G mobile phones. The implications of the proposed approach, considering the digital transformation concept, could be a topic for future research.
