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.

Insights into podophyllotoxin lactone features: New cyclolignans as potential dual tubulin-topoisomerase II inhibitors. [PDF]

Arch Pharm (Weinheim)
Podophyllotoxin is a natural product with interesting antitumor properties that still presents enormous possibilities for chemomodulation of its activity. New strategies of structural modification were explored, targeting both cyclolignan mechanisms of action, tubulin polymerization, and topo II inhibition, finding interesting cytotoxic properties ...

Solubility and Efficiency of Rock Phosphate Fertilizers Partially Acidulated with Zeolite and Pillared Clay as Additives

Agronomy, 2020
Soluble phosphates are the most common sources currently used in crop production in tropical soils; however, they present low efficiency and are more expensive than natural rock phosphates. The objective was to develop new phosphate fertilizers with slow

Studies on the Acidulation of Soft Phosphate

Poultry Science, 1965
Abstract A NUMBER of studies have been conducted to compare the utilization of phosphorus from soft phosphate and other phosphorus sources. The majority of these reports have indicated poor availability of the phosphorus from this source. These studies were reviewed by Motzok et al. (1956) and Nelson and Peeler (1961). Summers et al.
