Synthesis of 1,4-Disubstituted Mono and Bis-triazolocarbo-acyclonucleoside Analogues of 9-(4-Hydroxybutyl)guanine by Cu(I)-Catalyzed Click Azide-Alkyne Cycloaddition [PDF]
A series of novel mono-1,2,3-triazole and bis-1,2,3-triazole acyclonucleoside analogues of 9-(4-hydroxybutyl)guanine was prepared via copper(I)-catalyzed 1,3-dipolar cycloaddition of N-9 propargylpurine, N-1-propargylpyrimidines/as-triazine with the ...

This review examines the critical role of neighboring active motifs in heterogeneous catalysts, emphasizing how their synergistic cooperativity can be rationally designed to modulate catalytic properties. The discussion centers on the modulation of electronic and geometric structures, categorizing the catalytic systems into metal‐acid (Brønsted/Lewis ...

Microwave assisted metal-free approach to access 1,2,3-triazoles through multicomponent synthesis
The work illustrates multicomponent reaction of aldehydes, nitroalkanes and sodium azide for the metal-free synthesis of N-unsubstituted-1,2,3-triazoles using anthranilic acid as an organocatalyst under microwave irradiation. This is the first ever green

Designing Physical Unclonable Functions From Optically Active Materials
Assigning unforgeable “fingerprints” to manufactured goods is a key strategy to fight global counterfeiting. Optical physical unclonable functions (PUFs) are chemically generated random patterns of optically active materials serving as unique authenticators.

Rice seeds of the temperate japonica cultivar Kitaake were mutagenized with sodium azide alone and in combination with methyl nitrosourea. Using the reduced representation sequencing method Restriction Enzyme Sequence Comparative Analysis (RESCAN), the mutation densities, types and local sequence context were determined in the resulting M2 generation ...

Sonicated Carbon Nanotube Catalysts for Efficient Point‐of‐use Water Treatment
The growing demand for freshwater and rising contamination of water sources require innovative treatment technologies. Sonicated carbon nanotubes can activate persulfate for selective contaminant degradation via nonradical pathways. This scalable approach enables rapid pollutant removal, offering a sustainable solution for decentralized freshwater ...

Site Selective Antibody-Oligonucleotide Conjugation via Microbial Transglutaminase. [PDF]
Nucleic Acid Therapeutics (NATs), including siRNAs and AntiSense Oligonucleotides (ASOs), have great potential to drug the undruggable genome. Targeting siRNAs and ASOs to specific cell types of interest has driven dramatic improvement in efficacy and ...

2D organic semiconductors are widely believed to have uniformly active surfaces. This study reveals that their basal planes can be pseudo‐inert due to anisotropic exciton migration. By inducing exciton self‐trapping through dimensional reduction, these inert planes are activated, boosting hydrogen peroxide production by over 350%. The work uncovers key
