“…Straight or neat oils consist of aliphatic hydrocarbons that are water-immiscible and derived from petroleum. Water-miscible oils can be either naphthenic or paraffinicbased, while both semi-synthetic and synthetic oils are mineral oil-based (Ibrahim et al, 2023). The global market for MWFs was estimated to be USD 11.1 billion in 2022 and is projected to reach USD 15.9 billion by 2032, with an annual growth rate of 3.7% from 2023 to 2032 (ACUMEN, 2023).…”

As climate change intensifies and the need to reduce human-caused emissions becomes more urgent, transitioning to a bio-based economy is essential. This paper explores the diverse industrial applications of plant oils as sustainable alternatives to petroleum-based products, including their use in food, polymers, lubricants, surfactants, pesticides, emollients, and biofuels. This review delves into biosynthetic pathways, detailing the key enzymes and processes involved in the synthesis of triacylglycerol. It thoroughly discusses how genetic and metabolic engineering can not only increase oil yields but also modify fatty acid compositions to better meet industrial requirements. By understanding genetics and utilizing advanced biotechnologies, the oil content and quality of plant sources can be significantly enhanced, aligning with both sustainability goals and industrial demands. This paper provides a comprehensive overview of the current uses and genetic engineering of plant oil production, proposing innovative strategies such as utilizing oils from biomass or cultivating non-edible oil crops. These approaches aim to establish a sustainable industrial system, reduce reliance on fossil fuels, and promote the growth of an environmentally responsible bio-based economy. Additionally, the review highlights future directions, examining the economic implications and environmental benefits of adopting plant oils across various sectors and positioning them as pivotal to achieving an eco-friendly, bio-based economy.

“…If economic conditions permit and there is a high demand for part quality, superhard abrasive grinding wheels and corresponding dressing facilities can be equipped [20,21]. Otherwise, cooling methods such as cryogenic minimal-quantity lubrication can be chosen to break through the gas barrier and achieve enhanced heat transfer [22,23]. How to establish effective suppression schemes based on the formation mechanisms of thermal damage in high-strength steel grinding has become an important direction for future scientific development.…”

Creep−feed grinding of high−strength steel is prone to excessive wheel wear and thermal damage defects, which seriously affects the service performance of parts. To solve the above−−mentioned issue, a creep−feed grinding test was carried out on high−strength steel using SG and CBN abrasive wheels. The grindability of high−strength steel was scrutinized in terms of grinding force, machining temperature and grinding specific energy. Moreover, the effects of operation parameters and grinder performances on the surface integrity of the workpiece such as surface morphology, roughness, residual stress and hardness were rigorously studied. The results indicate that, when the instantaneous high temperature in the grinding area reaches above the phase transition temperature of the steel, the local organization of the surface layer changes, leading to thermal damage defects in the components. The outstanding hardness and thermal conductivity of CBN abrasives are more productive in suppressing grinding burns than the high self−sharpening properties of SG grits and a more favorable machining response is achieved. The effects of thermal damage on the surface integrity of high−strength steel grinding are mainly in the form of oxidative discoloration, coating texture, hardness reduction and residual tensile stresses. Within the parameter range of this experiment, CBN grinding wheel reduces grinding specific energy by about 33% compared to SG grinding wheel and can control surface roughness below 0.8 µm. The weight of oxygen element in the burn−out workpiece accounts for 21%, and the thickness of the metamorphic layer is about 40 µm. The essential means of achieving burn−free grinding of high−strength steels is to reduce heat generation and enhance heat evacuation. The results obtained can provide technical guidance for high−quality processing of high−strength steel and precision manufacturing of high−end components.
