Silicon-mediated modulation of maize growth, metabolic responses, and antioxidant mechanisms under saline conditions

BMC Plant Biology, Journal Year: 2025, Volume and Issue: 25(1)

Published: Jan. 2, 2025

This study explored how exogenous silicon (Si) affects growth and salt resistance in maize. The maize was cultivated sand-filled pots, incorporating varied stress (NaCl) treatments. Silicon applied at 0, 2, 4, 6, 8 mM, induced using 60 and120 mM concentrations. Soil salinity triggers a range of physiochemical abnormalities, often leading to arrest and, eventually, the demise susceptible plants. significantly reduced total chlorophyll content (12.58–33.14%), antioxidant enzymes, notably SOD (32–46%), POD (10.33–18.48%), CAT (10.05–13.19%). In contrast, increased secondary metabolites, including phenols (49.11–66.35%.), flavonoids (220.99–280.36%), anthocyanin (50.04–58.6%). Adding under absorption Na+ by 6.69%, 20.7%, 41.12%, 34.28%, respectively, compared their respective controls. Additionally, applying Si enhanced enzymes such as (50.57%), (15.58%), (10.06%) ratio (21.32%). application positively impacted nearly all physiological features, indicating it helps mitigate against salinity. achieved regulating various indicators, where anthocyanin, ascorbic acid, phenols, flavonoids, increased.

Modeling Indium Extraction, Supply, Price, Use and Recycling 1930–2200 Using the WORLD7 Model: Implication for the Imaginaries of Sustainable Europe 2050

Natural Resources Research, Journal Year: 2024, Volume and Issue: 33(2), P. 539 - 570

Published: Jan. 31, 2024

Abstract The increasing need for indium in photovoltaic technologies is set to exceed available supply. Current estimates suggest only 25% of global solar cell demand can be met, posing a significant challenge the energy transition. Using WORLD7 model, this study evaluated sustainability production and overall market model considers both mass balance dynamic interplay supply–demand determining prices. It estimated that total 312,000 tons extracted. However, primary hindrance supply availability extraction opportunities necessary infrastructure. Unless we improve capacity, may face shortages, hindering advancement pivotal technologies. A concern observed insufficient rate recycling. Boosting could greatly alleviate pressures. Projections indicate will reach its peak between 2025 2030, while panels due shortages anticipated around 2090, with an installed capacity 1200 GW. Thus, growth lag behind actual demand. For sustainable future, understanding role essential metals like crucial. European Environment Agency (EEA) introduced four “imaginaries” depicting visions Europe by 2050 (SE2050), each representing unique future within specific parameters. Currently, heavily dependent on imports tech has limited recycling capabilities, putting it at disadvantage context. To achieve sustainability, there improved infrastructure extraction, recycling, conservation such as indium. These resources are crucial realizing Europe’s objectives. Furthermore, these wider overarching strategies vital envisioning Union 2050, depicted Imaginaries.

Copper Molybdate-Catalyzed Esterification of Levulinic Acid: A Heterogeneous Approach for Biofuel Synthesis

Catalysts, Journal Year: 2025, Volume and Issue: 15(4), P. 357 - 357

Published: April 6, 2025

The catalytic esterification of levulinic acid (LA) to methyl levulinate (ML) was investigated using copper molybdate (Cu3(MoO4)2(OH)2) as a heterogeneous catalyst. catalyst, synthesized via chemical precipitation, exhibited monoclinic structure with self-assembled nanoplates forming spherical mesostructures. Structural characterization confirmed its high crystallinity, while textural analysis revealed BET surface area 70.55 m2 g−1 pore sizes in the nanometric range (1–6 nm). performance systematically evaluated under varying reaction conditions, including temperature, catalyst dosage, time, methanol-to-LA molar ratio, alcohol type, and reusability. Optimal conversion 99.3% achieved at 100 °C, 1:20 5% loading, time 4 h. Comparative other catalysts demonstrated superior efficiency stability Cu3(MoO4)2(OH)2, minimal activity loss over four reuse cycles (final 77.1%). Mechanistic insights suggest that is attributed Lewis Brønsted sites, facilitating efficient esterification. This study underscores potential sustainable recyclable for biofuel additive synthesis, advancing green chemistry strategies biomass valorization.

The Human Ecology of Overshoot: Why a Major ‘Population Correction’ Is Inevitable

World, Journal Year: 2023, Volume and Issue: 4(3), P. 509 - 527

Published: Aug. 11, 2023

Homo sapiens has evolved to reproduce exponentially, expand geographically, and consume all available resources. For most of humanity’s evolutionary history, such expansionist tendencies have been countered by negative feedback. However, the scientific revolution use fossil fuels reduced many forms feedback, enabling us realize our full potential for exponential growth. This natural capacity is being reinforced growth-oriented neoliberal economics—nurture complements nature. Problem: human enterprise a ‘dissipative structure’ sub-system ecosphere—it can grow maintain itself only consuming dissipating energy resources extracted from its host system, ecosphere, discharging waste back into host.
