Eco‐Friendly Synthesis of Cobalt Phthalocyanine for High‐Efficiency CO2${\rm CO}_{2}$ Electroreduction

Chemistry – A European Journal, EarlyView.
A sustainable synthesis of cobalt phthalocyanine (CoPc) using low‐impact solvents yields high‐performance electrocatalysts with reduced waste (E‐factor 18.6). When integrated into gas diffusion electrodes, CoPc achieves up to 12% Faradays efficiency for CO2‐to‐methanol and 65% CO2‐to‐CO conversion, aligning with state‐of‐the‐art materials and enabling ...

Late‐Stage Modification of Halotryptophan‐Containing Peptides Via Negishi Cross‐Coupling

Chemistry – A European Journal, EarlyView.
Negishi cross‐coupling provides access to the late‐stage functionalization of bromotryptophan‐containing peptides under comparatively mild conditions and is applicable to a range of peptide substrates in the investigated model systems. The examined alkyl iodides and variation of N‐terminal residues demonstrate the feasibility of the transformation in a

Metal‐Ion Regulated Light‐Free Z→E Isomerization of Azobenzene Glycomacrocycle

Chemistry – A European Journal, EarlyView.
Metal ion‐catalyzed Z→E isomerization of photoswitchable azobenzene glycomacrocycle: A new azobenzene‐based glycomacrocycle is capable of forming a 1:1 complex with divalent metal ions in both E‐ and Z‐isomers. The complexes undergo light‐free Z→E isomerization in a timescale spanning from seconds to weeks.

Stepwise Synthesis of Tetrabenzotriazaporphyrins (TBTAPs) and Their Open 2‐ and 3‐Ring Fragments

Chemistry – A European Journal, EarlyView.
Unexpected reaction pathways to porphyrin‐phthalocyanine hybrids are uncovered by the synthesis of “half‐macrocycle” fragments and subsequent macrocyclization. Rather than the expected 2:2 “ABBA” product, the 3:1 “ABBB” hybrid is isolated as the only macrocyclic product.

Influence of Particle Size, Moisture, and Cloud Density on Wood Dust Ignition

Chemie Ingenieur Technik, EarlyView.
The ignition and combustion of particle clouds are strongly affected by particle interactions. This study uses spectroscopy to examine effects of particle size, water content, and cloud density. Results show ignition delay rises with larger size and density, whereas combustion duration depends mainly on water and density due to moisture‐driven ...

Peroxodisulfate‐Enhanced Leaching of Deep‐Sea Manganese Crusts and Sulfides

Chemie Ingenieur Technik, EarlyView.
Ammonium peroxodisulfate enables efficient leaching of deep‐sea manganese crusts and massive sulfides while offering electrolytic recycling. High leaching yields for V, Mn, Co, Mo, Sn, and W, along with complete leaching of As and Sb, highlight its potential as a powerful and sustainable oxidant for marine resource processing.

Impacts of refining Canadian partially upgraded bitumen: Fluid catalytic cracking

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract In this study, we examine the fluid catalytic cracking (FCC) performance of vacuum gas oil (VGO) from partially upgraded bitumen (PUB), a novel refinery feedstock from Canadian bitumen. FCC experiments were conducted in a lab‐scale FCC unit with VGOs from two different PUBs prepared using thermal cracking and solvent deasphalting, along with ...
