A cross-sectional online survey was conducted using multiple online channels, where hundreds of responses were recorded from seven different countries, in order to provide a better understanding of the global public opinion about the awareness, perception and attitude about climate change. The results reflected that majority of people believe in the actual happening of Climate Change both by natural as well as anthropogenic causes. While most respondents believed in the anthropogenic causes of climate change, some people still displayed their confidence in the natural causation of climate change and thus affirmed their awareness of its natural causes. There was however, a difference of opinion regarding the mechanism behind the greenhouse effect. The respondents also provided their opinion on the impact of carbon aerosols on the atmospheric temperature. Further, the respondents were optimistic on the issue of climate change reversal and had also preferred some mitigation steps such as the use of geo-engineering over adjusting to the existing impacts of climate change. Although, people confirmed their belief in the human-induced nature of climate change, yet their agreement of having faced bizarre things about climate change like the lack of consensus among the scientists and climate change being a hoax shows their unawareness about the appropriate knowledge and the propaganda against this planetary emergency. Therefore, this study could prove helpful for policy makers and other stakeholders as it shows how much is done and how much more is pending.

During the last half-century, the CO2 concentration in the world’s atmosphere has increased from 310 p.p.m. to over 380 p.p.m. This is due to the widespread usage of fossil fuels as a main source of energy. Modeling forecasts have shown that this trend will continue to rise and reducing CO2 emissions is a challenging task for multi-stakeholders, including research institutions. The UN Climate Change Conference in Glasgow (COP26) has stressed that stakeholders need to work together to achieve a NetZero target. Technologies involving absorbents for the capture of CO2 from a gas mixture are energy-intensive. Carbon adsorption and conversion (CAC) approaches have been gaining attention recently since these technologies can mitigate CO2 emissions. In this review, materials ranging from advanced carbon-based materials to natural resources-based materials will be reviewed. Adsorption and conversion capacities as well as the scalability possibility of these technologies for solving the CO2 emission problem will be investigated. The review, therefore, is timely and meaningful concerning the net zero emission targets set by countries and developmental organizations worldwide.

This study aims at exploring the improvement in extreme pressure (EP) properties with addition of natural Garlic oil as EP additive. Comparative investigations were conducted on PAO4 base oil, Natural Garlic oil (NGO) and PAO4 +1 wt. % NGO (Natural Garlic Oil) for evaluating the extreme pressure properties. The EP tests were conducted on a four ball tester according to ASTM D 2783. The results revealed that NGO possesses significantly good extreme pressure properties having a weld load of 3087N and load wear index of 513N. The results also revealed that NGO could significantly improve the weld load and load wear index of PAO4 base oil. After adding 1 wt. % garlic oil to PAO4 the load wear index increased by 62.51% and weld load increased by 25%. This study proposes garlic oil as a replacement to the use of nano-particles as EP additives and aims to eliminate the disadvantages that are prominent with nano-particles without comprising the performance.
