Introduction of a Double‐Headed Nucleotide Into G‐Quadruplex DNA: Position‐Dependent Stabilization and Structural Insights

Chemistry – A European Journal, EarlyView.
A double‐headed bis‐guanine (G) nucleotide (GG) was evaluated as a noncanonical building block in G‐quadruplexes (G4s). Biophysical and computational analyses reveal that GG can directly participate in G‐tetrads and strongly stabilize G4s in a position‐ and topology‐dependent manner. These findings establish design rules for using GG to engineer highly

Electrochemiluminescence of Heteroleptic Iridium(III) Complexes Featuring Substituted 2,4‐diphenylpyridinato Ligands

Chemistry – A European Journal, EarlyView.
Five heteroleptic iridium(III) complexes bearing cyclometalated 2,4‐diphenylpyridinato ligands were synthesized and their electrochemiluminescence (ECL) investigated. Two different coreactants were evaluated: tri‐n‐propylamine and benzoyl peroxide under anodic and cathodic potentials, respectively.

Impact of A‐Site Sr Substitution in LaFeO3 on Syngas Selectivity During Chemical Looping Dry Reforming of Methane (CL‐DRM)

Chemistry – A European Journal, EarlyView.
Sr doping regulates oxygen exchange and methane activation in LaFeO3, suppressing nonselective CH4 cracking and coke formation during CL‐DRM. La0.7Sr0.3FeO3 provides the optimal balance, delivering ∼40% CH4 conversion, an H2/CO ratio of 2, and >95% carbon balance.

Composition of Purified CO2 From Steel Mill Processes—A Classification and Analytical Comparison With Commercial CO2

Chemie Ingenieur Technik, EarlyView.
Due to the severe catalyst poisoning effect of certain trace components, the purity of CO2 is the main attribute to qualify it as syngas for further downstream processes. This study uses PTR–MS to investigate the trace components of the CO2 produced within the Carbon2Chem project.

Microwave‐assisted catalytic pyrolysis of textile wastes: Synergistic effects and product characteristics

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study examines the microwave‐assisted catalytic pyrolysis (MACP) of individual and blended textiles (cotton, polyester, nylon 6) using ZnO and a ZnO/natural zeolite catalyst. In a custom‐built microwave reactor operated at 500°C, 1 kW power, and a 15‐min residence time, textile wastes were pyrolyzed.
