The problem of corrosion of materials has lasted for a long time, corrosion causes damage to the structure of buildings and bringing loss of economy. The coating method, which is an easy and economical way to solve the problem, is still unable to satisfy the needs limited by the paints properties. However, this can be solved by introducing graphene, by its special 2-D material properties, to the paint. And a lot of researchers are working on this now. This paper mainly focuses on the overview of how graphene be applied to anti-corrosive coatings, the problems that are faced, what are solutions for those, and what are the advantages that graphene has in the area. Resulting that graphene is mainly used with organic anti-corrosion materials, by filling the holes in those materials to stop the corrosion molecules from infiltrating through. Graphene can also be used as containers, carrying corrosion inhibitors that would be released and fill the crack when the coating is damaged. By modifying graphene, problems like agglomeration and accelerating corrosion can be solved. The result will be used for researchers who are looking for a conclusion in the graphene anti-corrosive coatings research area and provide the main focuses and details.

Natural substances that are capable of being replaced or renewed over the course of a human lifetime or over a relatively short amount of time through natural processes are referred to as material that is renewable. Due to the fact that these materials are both sustainable and favorable to the environment, they are frequently used in a variety of industries, including the building industry, the textile industry, the energy industry, and the packaging industry. Given the circumstances, it is quite probable that this will have a profound effect on the future of humanity. Renewable materials commonly encompass biomass, bio-based polymers, natural fibers, wood, and lumber. The main focus of the study is to explore the utilization of renewable materials in green chemistry, namely biomass-sourced renewable materials, as well as other renewable materials such as food waste, recyclable plastics, and paper. This paper provides an in-depth review of the advantages and challenges related to renewable materials in the realm of green chemistry.

This research paper studies the impacts of HVAC system scheduling and building envelope material properties on the building energy efficiency in the downtown New York City, metropolitan area, that is highly associated with Urban Heat Island. By utilizing EnergyPlus for whole energy building simulation, the research compares two HVAC operational cases: a baseline case with constant temperature setpoints, and an occupancy-based temperature setpoint schedule. The study also investigated the influence of thermal conductivity variations in stucco exterior wall materials, with three cases, the default baseline thermal conductivity and a 15% variance, respectively. Results indicate that occupancy-driven scheduling significantly reduces energy consumption by approximately 16% annually compared to baseline. Conversely, the influence of thermal conductivity on energy consumption is minimal, with only a 0.35% deviation noted in response to a 15% variation in thermal conductivity. This suggests that both optimizing HVAC scheduling and the thermal conductivity of building envelope materials can save building energy consumption while optimizing HVAC scheduling has a relatively stronger impact than optimizing the thermal conductivity with a 15% variance in downtown New York City.

The energy consumption level in transportation is projected to continue its current upward trend until the year 2040. Motor gasoline and diesel are the most consumed energy sources in common transportation, followed by jet fuel and natural gas. Regrettably, biofuel and electric energy, which are renewable energy sources, had only a little contribution to overall energy consumption in transportation. This indicates that the use of renewable energy sources in transportation is still in its early stages. The rapid advancement of energy innovation is causing alarm among the general people. In 2020, greenhouse gas emissions from transportation reached a record high. In order to predict the future trajectory of renewable energy, it is crucial to closely monitor the utilization of nonrenewable energy sources in transportation, which is currently at a high level. This study examines the existing energy sources in China and utilizes reliable research papers and data to demonstrate the practicality of several energy advancements in current transportation systems. The study will employ a literature review method to examine the advancements in energy innovation within the domains of internal combustion engines and electric motors in automobiles, waterborne transportation, and aircraft.

Superconducting materials, discovered in the early twentieth century, have fascinated scientists with their unique attributes. This review provides a thorough exploration of superconductivity, tailored for newcomers, aiming to be a foundational resource for future research. It traces the evolution of different superconductors, including traditional, cuprate, and non-copper oxide types, detailing their specific characteristics. Central to the review is the examination of theoretical foundations, particularly the BCS theory, and the diverse applications of superconductors in high-performance magnets, energy transmission, and quantum computing. However, the practical deployment of superconductors is limited by challenges, notably their operation at extremely low temperatures, hindering widespread use. Furthermore, economic and technical difficulties in production and maintenance persist. To advance superconductors' potential, research must focus on enhancing critical temperatures and current density and developing cost-effective manufacturing techniques. This will enable novel applications in energy, transportation, and healthcare, driving technological progress.

Jilin City is one of the top ten famous Chinese cities worth introducing to the world. To further improve the construction of urban infrastructure and meet the needs of the economic and social development of Jilin City, the Jilin City Government Joint Development and Reform Commission and the Ecological Environment Bureau decided to expand and renovate the former Jilin City wastewater treatment plant. This study designs a wastewater treatment plant by comprehensively considering the policy needs and the local basic background characteristics of Jilin to solve the wastewater overflow problem. The design modified the anaerobic tank and Carroussel oxidation ditch processes, which have more advantages than traditional treatment processes, mainly including better BOD, nitrogen and phosphorus removal efficiency, less power consumption, and lower operating costs. This treatment plant design contains two special characteristics: the design considers the overall plan and pipeline layout of the wastewater treatment plant, and the size data of each module are calculated through theoretical study conforming to the real case.

Microplastic pollution has become a global problem, threatening water bodies and aquatic organisms around the world. Heavy metal pollution in the aquatic environment is an environmental issue of long-term concern, and relatively few studies have been conducted on the compound toxic pollution of freshwater algae by microplastics and heavy metals. Therefore, in this study, Cd and polystyrene (PS) were selected as representative heavy metals and microplastics in the environment, and the toxic effects of the two pollutants on freshwater algae were investigated by determining the biomass of algal growth, chlorophyll a content, and the bioconcentration of heavy metals. It was found that the two pollutants alone could inhibit the growth and photosynthesis of the algae, and the toxicity increased with the increase of concentration. When the two pollutants were combined, the toxicity of Cd depended on the concentration of PS, and both low (1 mg/L) and high (100 mg/L) concentrations of PS increased the toxicity of Cd in a synergistic manner, whereas the medium concentration (10 mg/L) of PS showed an antagonistic effect, which was able to inhibit the toxicity of Cd.
