Abstract: Today's societies consider the transportation sector as a key component of the economy that contributes significantly to sustainability and global economic development. However, the challenges resulting from transportation are expected to increase more seriously in the years to come in light of socioeconomic growth and increasing living standards. One of the most unfavorable outcomes of the transportation industries is climate change, which necessitates sustainable strategies to reduce emissions of greenhouse gasses. Although the use of electric vehicles (EVs) has obvious social advantages, including improvements to air quality along with beneficial effects of reducing CO2 emissions, EVs are being adopted quite slowly as a clean and green alternative form of transportation in Malaysia. Therefore, the present study has focused on the factors which affect consumers’ intention to use EVs in the Malaysian context. An extensive review of previous studies was carried out to identify the determinants of adopting EVs in the prior literature. The survey questionnaire was designed with reference to the decision-making trials alongside the Decision-Making Trials and Evaluation Laboratory (DEMATEL) method, after which questionnaires were distributed to Malaysian consumers of EVs. According to the results of the data analysis, environmental concern, trust in EVs, personal norms, price value, attitudes regarding EVs, and subjective norms are the most important factors influencing the adoption of EVs in the Malaysian context. The findings of the study provide directions for policymakers and automotive manufacturers.

Abstract: Hydrogen is a clean fuel which has the potential to drastically decarbonize the energy supply chain. However, hydrogen storage is currently a key challenge; one solution to this problem is hydrogen geo-storage, with which very large quantities of H2 can be stored economically. Possible target formations are deep coal seams, and coal permeability is a key parameter which determines how fast H2 can be injected and withdrawn again. However, it is well known that gas injection into coal can lead to coal swelling, which drastically reduces permeability. We thus injected H2 gas into a coal core and measured dynamic permeability, while imaging the core via x-ray micro-tomography at reservoir conditions. Importantly, no changes in coal cleat morphology or permeability were observed. We conclude that H2 geo-storage in deep coal seams is feasible from a fundamental petro-physical perspective; this work thus aids in the large-scale implementation of a hydrogen economy.
TL;DR: The authors found that tourists who see deviant other-tourist behavior have significantly stronger deviant behavioral intentions, and large and cohesive travel groups attenuate this effect, and moral disengagement mediates the social contagion effect.

TL;DR: In this article , the authors proposed a novel in-situ synthesis strategy of designing master alloys decorated with well-dispersed TiCxNy and TiB2 particles to synergistically optimize the Al-Si based composites.
Abstract: Tuning solidification microstructure remains a grand challenge for ceramic particles reinforced Al-Si based composites due to adverse interactions between ceramic particles and Si-containing melts. This work proposed a novel in-situ synthesis strategy of designing master alloys decorated with well-dispersed TiCxNy and TiB2 particles to synergistically optimize the Al-Si based composites. By adjusting the reactant contents and ratios, near-spherical nano-sized TiCxNy particles and hexagonal submicron-sized TiB2 particles were obtained in as-synthesized Al-(TiCxNy-TiB2)p master alloys. The effects of this pre-dispersed agent on solidification kinetics, microstructure features and mechanical performance evolution of the Al-10Si-2Mg composites were investigated in detail. TiCxNy-TiB2 particles could trigger the heterogeneous nucleation of primary α-Al crystals, and the growth-restricting effects also contributed to grain refinement, which finally accounted for the enhancement in both strength and ductility. This work is expected to provide new guidance for selection of reinforcing particles and synergistic optimization of the solidification microstructure and performance.

TL;DR: In this article , a mixed-methods consumer survey and in-depth interviews with food supply stakeholders were conducted in regional Australia, more specifically South West Western Australia between May and July 2020, immediately after the first wave of the pandemic.
Abstract: The COVID-19 pandemic has impacted the Australian food supply through changed consumer purchasing patterns, and potentially, household food security. The aim of this study was to determine the impact of COVID-19 on the prevalence of food insecurity and food supply issues, and perspectives of food supply stakeholders in regional Australia.A mixed-methods consumer survey and in-depth interviews with food supply stakeholders were conducted in regional Australia, more specifically South West Western Australia between May and July 2020, immediately after the 1st wave of the pandemic.The prevalence of food insecurity was 21% among consumers, and significantly more prevalent for those aged less than 30 years and living with a disability. Most consumers (73%) agreed that the COVID-19 pandemic had impacted the food supply. Food insecure respondents were more likely to report that food was more expensive, resulting in changes to the types and quantities of food bought. Food supply stakeholders perceived that consumers increased their intention to buy locally grown produce. Panic buying temporarily reduced the availability of food for both food suppliers and consumers, regardless of their food security status.This study provided novel insights from South West Australian consumer and food supply stakeholder perceptions. Food insecure consumers provided insights about the high cost of food and the subsequent adaptation of their shopping habits, namely type and amount of food purchased. Stakeholder perceptions largely focused on supply chain issues and corroborated consumer reports.

TL;DR: In this article , the contact angles of a brine on the surface of a bituminous coal in a pressurized hydrogen atmosphere were investigated and it was shown that hydrogen pressure increased brine contact angles at 25°C but did not have an impact at 50 or 70°C.
Abstract: Hydrogen storage is a main issue in the establishment of a hydrogen economy. Geo-storage could be a viable solution if hydrogen could be injected into and withdrawn from suitable geological formations, reversibly and reliably. Rock wettability is a major factor as it affects injectivities, withdrawal rates, storage capacities, and containment security. We report here the contact angles of a brine on the surface of a bituminous coal in a pressurized hydrogen atmosphere. Under realistic geo-storage conditions the coal surface was weakly water-wet. Hydrogen pressure increased brine contact angles at 25°C but did not have an impact at 50 or 70°C. We present a thermodynamic model that describes the observed behavior. Our results would support the development of large-scale geo-storage technologies for hydrogen.
