Development of a vegetation canopy reflectance sensor and its diurnal applicability under clear sky conditions.
Front Plant Sci
January 2025
Jiangsu Collaborative Innovation Center of Regional Modern Agriculture & Environmental Protection, Huaiyin Normal University, Huai'an, China.
The spectral reflectance provides valuable information regarding vegetation growth and plays an important role in agriculture, forestry, and grassland management. In this study, a small, portable vegetation canopy reflectance (VCR) sensor that can operate throughout the day was developed. The sensor includes two optical bands at 710 nm and 870 nm, with the light separated by filters, and has a field of view of 28°.

Electronic address:
Biogenic volatile organic compounds (BVOCs) are emitted by urban vegetation and can interact with anthropogenic pollutants to generate secondary organic aerosols (SOA) that are atmospheric pollutants in urban environments. In urban forests, SOA comprise up to 90 % of all fine aerosols (particulate matter smaller than 1 μm [PM]) in the summer. PM can greatly affect urban air quality and public health.

PLoS One
January 2025
Faculty of Agriculture, Food and Nutrition, Weihenstephan-Triesdorf University of Applied Sciences, Weidenbach, Germany.
As global demand for meat continues to rise, alternative and sustainable methods of production are being explored. Cultivated meat (CM) is one such alternative that holds potential for sustainable production with less environmental impact. This study develops an approach to evaluate CM production based on agricultural feedstock.

The announcement raised the temperature in the debate on this regulation. We put forward suggestions, based on scientific knowledge as well as current EUDR research and implementation projects, on how the 12-month phasing-in period could be used wisely to promote sustainability transitions in deforestation-risk value chains.

Department of Chemistry, i-Center for Advanced Science and Technology (i-CAST), Innovation and Development Center of Sustainable Agriculture (IDCSA), National Chung Hsing University, Taichung, 402202, Taiwan.
Additives play a pivotal role in enhancing the efficiency of perovskite solar cells (PSCs), and carefully designed additives contribute to major breakthroughs in device performance. In this study, a series of novel A-π-A-type porphyrin derivatives-PPH-1, PPH-2, and PPF-1-are synthesized, each incorporating pyridyl groups, specifically engineered to function as passivation agents for PSCs. The electron-withdrawing properties of fluorine in PPF-1 increase the molecular polarity, thereby strengthening its interaction with the perovskite and enhancing the passivation efficacy.
