State‐Level Politics in Forest Governance: The Role of the Narrative‐Policy Nexus in the Brazilian Amazon

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Deforestation and its social impacts are an enduring challenge in agrarian frontiers, especially in the tropics. Fueled by global demand for commodities, this process is mediated by ideas, concepts, meanings, and policies that uphold socioenvironmental degradation. A key and understudied—arena in which this mediation occurs is the sub‐national

A Highly Stable Zinc‐Mimosinate Metal–Organic Framework for Controlled Agrochemical Delivery

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
The graphical abstract illustrates the design of metal–organic frameworks (MOFs) as agrochemicals constructed from active building blocks. The highly robust GR‐MOF‐25 is assembled from the natural herbicide L‐mimosine and Zn2+ ions, combining herbicidal, micronutrient, and antibacterial properties.

Performance of the Groenevelt and Grant Model for Fitting Soil Water Retention Data from Brazilian Soils

open access: yesRevista Brasileira de Ciência do Solo
The soil water retention curve (SWRC) is essential for vadose zone hydrological modeling and related applications. In 2004, Groenevelt and Grant (GRT) presented a mathematical model for describing the SWRC and reported its mathematical versatility and ...

Performance Comparison of Monocrystalline, Polycrystalline, Low Concentrated, and Bifacial PV Modules in a Particular Geographic Location of South India

open access: yesEnergy Science &Engineering, EarlyView.
This study aims to conduct a performance comparison of irradiation and temperature on different commercially available PV modules like PPVM, MPVM, LPVM, and BPVM. Here, the TPVM is not considered in the analysis due to its toxic nature. This study has considered the LPVM because researchers have not focused on it due to the higher area requirement for ...

Biodegradable Coatings with Essential Oils for Combating Papaya Anthracnose: State of the Art and Perspectives

open access: yesFood Bioengineering, EarlyView.
ABSTRACT Papaya (Carica papaya L.) production and marketability are strongly constrained by postharvest diseases, with anthracnose caused by Colletotrichum spp. representing the most significant threat. Traditional control relies on synthetic fungicides, which, although effective, face challenges such as the development of pathogen resistance ...
