Poly(L-lactide) (PLLA), a biodegradable polymer with properties comparable to conventional plastics, is limited by its inherent brittleness and thermal instability. This study explores the enhancement of PLLA properties through the synthesis of ABA-type block copolymers with distinct soft middle blocks—polyester poly(methylricinoleate) (PMR) ...

Intensive mining of fossil fuels has caused the exhaustion of nonrenewable natural resources, water, and air pollution,  and significant deterioration and degradation of soils. One of the main problems associated with electricity generation from coal combustion is the “energy waste” issue. When analyzing the potentially harmful env...

Food, especially cereals and vegetables, water and air are the major source of exposure to toxic metals like cadmium (Cd), lead (Pb), arsenic (As) and mercury (Hg). Their accumulation in the human body can lead to harmful effects over time. The EFSA panel on contaminants in the food chain (CONTAM) established a tolerable weekly intake (TWI) for Cd,...

Animal-based food is significant for human nutrition as it represents an easily digestible source of high-quality proteins, fatty acids, fat-soluble vitamins, and energy. Throughout evolution, humans developed anatomical, metabolic, and biochemical adaptations in the digestive tract, increasing dependence on nutritionally valuable food, such as a...

Polyphenols are a large group of plant secondary metabolites that can be employed as preservatives, antioxidants, and additives. Flavonoids, as an important group of polyphenols and natural antioxidants, may reduce oxidative stress in cardiovascular and neurodegenerative diseases, diabetes mellitus, asthma, and eye disorders. The objective of the p...

The radiative models used in the numerical simulations of the pulverized coal-fired furnaces can be divided into flux and zonal models. For the zonal models, furnace volume and walls are divided into volume and surface zones. For the calculations of the heat exchange, the direct and total exchange areas for each pair of the zones are needed. The pr...
