Developing a Computational Pipeline for Detecting Multi-Functional Antibiotic Resistance Genes in Metagenomics Data
Antibiotic resistance is currently a global threat spanning clinical, environmental, and geopolitical research domains. The environment is increasingly recognized as a key node in the spread of antibiotic resistance genes (ARGs), which confer antibiotic resistance to bacteria. Detecting ARGs in the …

Heterogenous catalysis of inorganic reactions
… The aluminosilicates act simultaneously as bi-functional catalysts, i.e. as proton acceptors (base catalysis) and as electron pair acceptors (Lewis acid catalysis). Thus, the two possible activation mechanisms that agree with the experimental observations, appear to be: i) association of a …
