Nuclear‐Spin Hyperpolarization of Biomolecules by Optically Enhanced NMR at Ultra‐High Field

open access: yesJournal of the Chinese Chemical Society, EarlyView.
This study shows that the sensitivity of liquid‐state NMR spectroscopy can be dramatically increased, with enhancement factors up to 160‐fold on a 1.1 GHz ultra‐high‐field NMR spectrometer. This advance exploits low‐concentration photochemically induced dynamic nuclear polarization (LC‐photo‐CIDNP) and it enables facile atomic‐resolution detection of ...

African Economic Growth Revisited

open access: yesJournal of International Development, EarlyView.
ABSTRACT This paper presents an updated analysis of the patterns of economic development in Africa over the last 60 years. The analysis stresses the heterogeneity of development trajectories among sub‐Saharan African (SSA) countries. We examine the joint dynamics of income and population in 35 SSA countries.

Nutritional and environmental determinants of maturation and disruption of the early life gut microbiome: A narrative review

open access: yesJournal of Parenteral and Enteral Nutrition, EarlyView.
Abstract The first 1000 days of life represent a critical window for gut microbiome assembly, with lifelong implications for child growth, immune development, and disease risk. This review synthesizes evidence on maternal, perinatal, and especially nutritional factors that influence early‐life intestinal colonization and highlights the consequences of ...

Toward Sustainable Enzyme Production From Agro‐Industrial Residues: Optimizing pH and Soyhull Particle Size in Fungal Fermentation

open access: yesJournal of Surfactants and Detergents, EarlyView.
Sustainable enzyme production from soyhull fermentation. ABSTRACT Carbohydrase enzymes are critical to sustainable detergent formulations, enabling effective cleaning at lower temperatures and reduced resource use. To improve the economic and environmental viability of enzyme production, this study explored soybean hulls—a low‐value agricultural by ...

Disclosing the production of fungal chitinases and proteases using insect by‐products as substrates in solid‐state fermentation

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND The world population is projected to reach nearly 9.7 billion by 2050, significantly increasing the demand for novel and sustainable protein sources. Edible insects, such as Tenebrio molitor, emerge as promising alternatives due to their high nutritional value, but adult insects and frass are direct and abundant by‐products of this ...

Future Soil Erosion Under Combined CMIP6 Climate Projections and Land Use/Land Cover Change: A RUSLE‐Based Assessment of the Kampe Omi Dam Basin in Nigeria

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Soil erosion remains a major environmental challenge in Nigeria, driven by the combined effects of climate variability and land use/land cover (LULC) changes. Understanding future dynamics is essential for effective soil conservation planning.
