Appropriate Use of Local Phosphate Rock Increases Phosphorus Use Efficiency and Grain Yield of Sorghum and Cowpea in the Sudan Savanna

Frontiers in Soil Science, 2022
Development of local P fertilizers using low-grade phosphate rock (PR) is expected to overcome the low-stagnated crop yield in Sub-Saharan Africa. Calcination and partial acidulation methods have been proposed to increase the phosphate (P) solubility of ...

The Effect of Phosphorus Fertilizer Sources and Lime on Acidic Soil Properties of Mollic Rhodic Nitisol in Welmera District, Central Ethiopia

Applied and Environmental Soil Science, Volume 2023, Issue 1, 2023., 2023
The soil acidity problem is intensified by improper utilization of synthetic fertilizers in addition to other naturally existing causes; thus, it is important to consider effects on soil health beyond seasonal crop productivity. Most widely used sources of soluble phosphate fertilizers cannot perform effectively on acidic soil due to its fixation ...

Bovidae‐based gelatin: Extractions method, physicochemical and functional properties, applications, and future trends

Comprehensive Reviews in Food Science and Food Safety, Volume 21, Issue 4, Page 3153-3176, July 2022., 2022
Abstract Gelatin is one of the most important multifunctional biopolymers and is widely used as an essential ingredient in food, pharmaceutical, and cosmetics. Porcine gelatin is regarded as the leading source of gelatin globally then followed by bovine gelatin. Porcine sources are favored over other sources since they are less expensive.

Phytostabilization of a contaminated military site using Miscanthus and soil amendments

Journal of Environmental Quality, Volume 50, Issue 5, Page 1220-1232, September/October 2021., 2021
Abstract Military activities can contaminate productive land with potentially toxic substances. The most common trace metal contaminant on military bases is lead (Pb). A field experiment was begun in 2016 at Fort Riley, KS, in an area with total soil Pb concentrations ranging from 900 to 1,500 mg kg–1 and near‐neutral pH.

Bifunctional Co‐based Catalysts for Fischer‐Tropsch Synthesis: Descriptors Affecting the Product Distribution

ChemCatChem, Volume 13, Issue 11, Page 2726-2742, June 8, 2021., 2021
Fischer‐Tropsch synthesis: The properties of Co/zeolite bifunctional catalysts were correlated to the product distribution in Fischer‐Tropsch synthesis. It is observed that both the acidity and the pore structure play a vital role in primary and secondary hydrocracking/isomerization reactions. Abstract The conversion of synthesis gas to hydrocarbons in

Stability of Cobalt Particles In and Outside HZSM‐5 under CO Hydrogenation Conditions Studied by ex situ and in situ Electron Microscopy

ChemCatChem, Volume 13, Issue 2, Page 718-729, January 20, 2021., 2021
Encapsulated cobalt particles live another day: Heterogeneously catalyzed reactions like the CO hydrogenation exhibit harsh conditions leading to catalyst deactivation. The cobalt particles investigated via ex situ and in situ TEM are located inside and outside the ZSM‐5 support, undergoing realistic and model conditions.
