Assessment of Organophosphate and Carbamate Pesticide Residues in Cigarette Tobacco with a Novel Cell Biosensor

Sensors, 2008
The conventional analysis of pesticide residues in analytical commodities, such as tobacco and tobacco products is a labor intensive procedure, since it is necessary to cover a wide range of different chemicals, using a single procedure.

Chromatography-free synthesis of carbamates from CO2 catalyzed by a green and recyclable biobased ionic liquid/Cu2O system

Journal of CO2 Utilization
Carbamates and related derivatives are crucial skeletons for pesticide design and pharmaceutical chemistry. Recently, a synthetic route for the production of carbamates has drawn great attention, which assembles the economical, renewable and non-toxic ...

Photoinduced Boron‐Catalyzed Direct α‐Aminoxylation of Carboxylic Acids

ChemistryEurope, EarlyView.
A boron‐catalyzed α‐aminoxylation of carboxylic acids enables rapid access to sterically congested α‐(aminoxy)carboxylic acids. Photoexcited diboron enediolates transfer energy to O‐sulfonylhydroxylamines, triggering SO bond cleavage to generate N‐oxyl radicals.

Synthetic Cathepsin B Sensitive Adjuvant‐Peptide Conjugates to Target Intracellular Toll‐Like Receptors 7 and 8

ChemistryEurope, EarlyView.
Cathepsin B‐sensitive peptide–adjuvant conjugates are designed, synthesized, and evaluated to deliver an antigenic peptid and an adjuvant targeting Toll‐like receptors 7 and 8 (TLR7/8) to antigen presenting cells. The adjuvant is released by cathepsin B resulting in antigen presentation and TLR mediated T cell activation.

Organophotoredox/Cobalt‐Catalyzed Retro‐Hydroformylation of Aldehydes

ChemistryEurope, EarlyView.
A new photoredox/cobalt retro‐hydroformylation is developed. This one‐pot two‐step process involves the in situ formation of the corresponding 1,4‐dihydropyridine as key intermediate. Under mild reaction conditions, alkenes are efficiently produced from a wide range of aliphatic α‐monosubstituted aldehydes, with high functional‐group tolerance.

Solvent‐Driven Pore Engineering in Coffee‐Derived Activated Hydrochar: Implications for Post‐Combustion CO2 Capture

Carbon Energy, EarlyView.
Solvent washing of coffee‐ground hydrochars produces activated carbons with tunable pore sizes while maintaining surface area. Removing non‐polar contaminants enhances microporosity, increasing CO2 uptake by 40%. Moderate pore sizes (9–12 Å) yield optimal CO2:N2 selectivity, whereas smaller pores reduce selectivity due to stronger interactions between ...
