Biomass-produced biocarbon has low surface functionality and a reduced pore volume, these properties reduce the performance of the biocarbon and limit its applications. Among the various surface engineering strategies, oxidation leads to both an increase in pore volume and surface functionality, by introducing oxygen-containing chemical groups. This study presents a short review of the oxidation pathways in surface engineering of biocarbon materials, evaluates the controlling factors, such as key parameters, that ...

In the oil extraction industry, large quantities of water are processed, which is extracted with the oil and gases from the deposits which is then used in the injection process. Water treatment is required because they contain various impurities that make them unsuitable for disposal in the environment. As these wastewater must be disposed of, the most appropriate way is to treat them and inject them into various underground layers. The most common use of wastewater is found in water injection processes to improve...

The purpose of the study was to present a case study on the parameters of photovoltaic systems installed on different types of roof. These research studies were conducted in the Laboratory of Renewable Energy at the University of Pite?ti.The case study analyzed the production of electricity for different photovoltaic systems, in terms of construction and placement.Mainly, the parameters of these systems were checked in the same weather conditions, such as: temperature, humidity, solar radiation and the unit of are...

Petroleum and its derivatives are the main source of energy for industry and domestic consumption. Petroleum hydrocarbons are based on multiple carbon bonds that develop intense and raised complex structures when they bound with other characteristic molecules, hence the latest hydrocarbons have variety of forms and consist of short, medium and long aliphatics, aromatics and polycyclic aromatic hydrocarbons of different proportions. The accidental release of these hydrocarbons into the environment represents a majo...
