Towards the Prediction of the Remaining Lifetime of a Carbon Filter Bed on Hydrogen Cyanide Challenge Using in-Bed Sensors and a Neural Network: Preliminary Findings

Adsorption Science & Technology, 1999
The residual lifetime of an activated carbon filter bed challenged by hydrogen cyanide, a chemisorbing gas, has been successfully predicted on one occasion using transducers embedded within the filter bed.

From Waste to Plant‐Based Protein: Impact of Solid‐State Fermentation on Functionality and Protein Extraction of Cassava Leaves

Cereal Chemistry, EarlyView.
ABSTRACT Background and Objectives Cassava leaves represent a significant waste stream in cassava cultivation, currently underutilized in both food and nonfood applications. This study investigates the use of solid‐state fermentation with Aspergillus oryzae, Lactobacillus plantarum, and Bacillus subtilis to modify the composition and functional ...

Synthesis and Crystal Structure of Benzyl [(1S)-1-(5-amino-1,3,4-oxadiazol-2-yl)-2-phenylethyl]carbamate

Crystals, 2012
The conversion of Z-phenylalanine hydrazide with cyanogen bromide resulted in the formation of the corresponding 2-amino-1,3,4-oxadiazole by spontaneous cyclization of the intermediary cyanohydrazide.

Chemical Methods for Peptide and Protein Backbone Cleavage

ChemistryEurope, EarlyView.
Protein cleavage plays essential roles in biology and is powerful for protein manipulation and functionalization as well as in recombinant expression and purification. Here, the historical background and most recent examples of chemical methods for protein and peptide backbone cleavage are discussed (part of the figure was generated in BioRender).

A Cometary Fluorescence Model for the ν3 Vibrational Band of Cyanogen

The Astrophysical Journal
Cyanogen (C _2 N _2 ) has been suspected for a long time to be present in comets and to contribute to the creation of the CN radical. So far no observations with ground-based facilities have managed to detect this species, but the Rosetta mission, thanks

Insect‐Derived Bioactives for Glycemic Control and Gut Health: A Review

Food Frontiers, EarlyView.
Insect‐derived bioactive compounds (e.g., peptides, polysaccharides) effectively regulate blood glucose through dual mechanisms: directly inhibiting carbohydrate‐digesting enzymes and glucose transporters, and indirectly modulating gut microbiota to enhance intestinal barrier integrity.
