This study delves into the sustainability of biomass-based energy as an alternative energy source, its technical conversion methods, and its environmental and economic impacts. Biomass resources, including plants, agricultural residues, and forestry residues, are not only widely distributed and renewable but also exhibit significant potential in reducing greenhouse gas emissions and combating climate change. The research focuses on three primary conversion technologies for biomass energy: physical conversion, chemical conversion, and biological conversion. It further explores key technologies

Photosynthesis is the largest mass- and energy-conversion process on Earth, and it is the material basis for almost all biological activities. The efficiency of converting absorbed light energy into energy substances during photosynthesis is very low compared to theoretical values. Based on the importance of photosynthesis, this article summarizes the latest progress in improving photosynthesis efficiency from various perspectives. The main way to improve photosynthetic efficiency is to optimize the light reactions, including increasing light absorption and conversion, accelerating the recover

Electromagnetic metasurfaces with excellent electromagnetic wave regulation properties are promising for designing high-performance polarization control devices, while the application prospect of electromagnetic metasurfaces is limited because of the current development situations of the complex structure, low conversion efficiency, and narrow working bandwidth. In this work, we design a type of reflective terahertz metasurface made of a simple structure that can achieve multiple polarization modulation with high efficiency. It is shown that the presented metasurface can realize ultra-broadban

Biofuels are the sustainable counterparts of fossil fuels to meet the increasing energy demands of the current and future generations. Biofuels are produced from waste organic residues with the application of mechanical, thermochemical and biological methods and processes. While mechanical and thermochemical conversion processes involve the use of heat, pressure, catalysts and other physicochemical attributes for the direct conversion of biomass, biological conversion requires microorganisms and their enzymes as biocatalysts to degrade the fermentable substrates into biofuels and biochemicals.

The use of renewable energies has seen a significant increase in energy demand in agriculture, in competition with solid, liquid or gaseous fossil fuels. Wood and other forms of biomass including energy crops, agricultural and forest biomass are transformed into energy through thermal, biological or physical processes. Thermo-chemical conversion, biomass gasification, is the most attractive technology that offers a high conversion efficiency compared to direct burning or rapid pyrolysis.

To meet the global demand poultry meat, poultry should be produced efficiently and sustainably. Feed constitutes 70% of the cost of poultry production, meaning improvements in feed efficiency would be beneficial to producers, consumers and the environment. Feed conversion ratio (FCR) is an economic trait preferred by producers because it is directly related to profitability. Different combinations of feed intake and body weight gain can provide the same FCR value and may have the same economic outcome but with different underlying biological causes. Residual feed intake (RFI) breaks down feed
