Effect of chemical–thermal activation on the properties of recycled fine powder cementitious materials

Case Studies in Construction Materials
Recycled fine powder (RFP) collected from construction and demolition waste resources is difficult to use in large quantities due to its low activity. To promote the activity of RFP and maximize its economic and environmental benefits, it is necessary to

Potential Use of Waste Activated Sludge Hydrothermally Treated as a Renewable Fuel or Activated Carbon Precursor

Molecules, 2020
In this work, dewatered waste activated sludge (DWAS) was subjected to hydrothermal carbonization to obtain hydrochars that can be used as renewable solid fuels or activated carbon precursors.

Efficient palladium-catalyzed electrocarboxylation enables late-stage carbon isotope labelling

Nature Communications
Carbon isotope labelling of bioactive molecules is essential for accessing the pharmacokinetic and pharmacodynamic properties of new drug entities. Aryl carboxylic acids represent an important class of structural motifs ubiquitous in pharmaceutically ...

A chemical activity approach to exposure and risk assessment of chemicals [PDF]

Environmental Toxicology and Chemistry, 2018
Abstract To support the goals articulated in the vision for exposure and risk assessment in the twenty-first century, we highlight the application of a thermodynamic chemical activity approach for the exposure and risk assessment of chemicals in the environment. The present article describes the chemical activity approach, its strengths and limitations,

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Nanoporous Carbon from Oil Palm Leaves via Hydrothermal Carbonization-Combined KOH Activation for Paraquat Removal

Molecules, 2022
In this study, nano-porous carbon was completely obtained from oil palm leaves (OPL) by hydrothermal pretreatment with chemical activation, using potassium hydroxide (KOH) as an activating agent. Potassium hydroxide was varied, with different ratios of 1:

tRNA as an active chemical scaffold for diverse chemical transformations [PDF]

FEBS Letters, 2009
During protein synthesis, tRNA serves as the intermediary between cognate amino acids and their corresponding RNA trinucleotide codons. Aminoacyl‐tRNA is also a biosynthetic precursor and amino acid donor for other macromolecules. AA‐tRNAs allow transformations of acidic amino acids into their amide‐containing counterparts, and seryl‐tRNASer donates ...

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
