A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

open access: yesBiological Reviews, EarlyView.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Impaired healing following implant placement surgery: A case report of a modern‐day manifestation of scurvy

open access: yesClinical Advances in Periodontics, EarlyView.
Abstract Background Delayed wound healing following implant placement surgery is an uncommon complication, usually attributed to systemic (smoking and alcohol), local (severely inflamed tissues), or technical (poor suturing) factors. However, delayed wound healing after implant placement caused by severe hypovitaminosis C has not been previously ...

Coal‐Based Anthraquinone Synthesized by Cascade Catalytic Hydrogenation and Oxidation

open access: yesCarbon and Hydrogen, EarlyView.
A cascade catalytic process has been proposed for the conversion of AN into the valuable AQ, utilizing a Pt/6MoOx/Al2O3 catalyst for hydrogenation to DHA and a RuOx‐Ce0.7Zr0.3O2 catalyst for oxidation, thus presenting an efficient route from coal to high‐value chemicals.

Synthesis of an Enzyme‐Triggered Chitosan‐Based Drug Delivery System for Peri‐Implantitis Prevention

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT Dental implants have become a leading solution for tooth loss, yet bacterial infections remain a major complication. Antibacterial implant coatings are an important approach to reduce or prevent bacterial infections at the implant. Given the oral cavity's complex microbiome and the importance of some commensal bacteria, it is crucial to ...

Bayesian Optimization of Solvent‐Free Thermal Amidation via Reactive Extrusion

open access: yesChemistry – A European Journal, EarlyView.
Thermal amidation between a carboxylic acid and an amine was successfully conducted in an extruder in the absence of solvent, coupling agent, or catalyst, relying on an adapted Bayesian Optimization protocol. Active pharmaceutical ingredient moclobemide was synthesized on a larger scale, achieving excellent yield and low Process Mass Intensity (PMI ...

Effect of the additive concentration on the modification of petroleum coke and anode quality

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Calcined petroleum coke is one of the major raw materials for anode manufacturing, which is used as the carbon source in electrolytic cells for primary aluminium production. It constitutes around 65%–70% of the anode recipe. Therefore, the quality of calcined coke has an important impact on anode quality, which affects the cost, energy ...

Transient thermal modelling of green anode cooling in the aluminium industry

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Summary of the methodology. Abstract Anodes, which are used in electrolytic aluminium production, are made by mixing dry aggregate (petroleum coke, rejected anodes, and butts) with coal tar pitch, compacting the resulting paste (green anode), and baking (baked anode). After compaction, the anodes are cooled to maintain their structural integrity before
