Effect of Thiourea on the Nanocrystalline-Copper Coating Prepared by Jet Electrodeposition

open access: yesInternational Journal of Electrochemical Science, 2019
Jet electrodeposition with the aid of thiourea was proposed in this paper to improve the deposition quality of copper coatings. The effects of the content in the electrolyte on the coating microstructures, morphologies and mechanical performances were ...

Spike‐Embedded Nanocatalysts via Metal‐Directed Carbonization for Highly Efficient and Robust Semi‐Hydrogenation

open access: yesAdvanced Science, EarlyView.
A metal‐directed carbonization strategy transforms hierarchical organic microspheres into spiky carbon catalysts with Pd nanoparticles embedded at the tips. This approach resolves the activity‐stability trade‐off, achieving exceptional poison resistance in semi‐hydrogenations, offering a versatile, scalable platform for designing high‐performance ...

Quantitative Photo‐Reforming of Biomass to CO Spurred by In Situ Protonation of Carbon Dioxide Radical Anions

open access: yesAngewandte Chemie, EarlyView.
A “two‐in‐one” photoreduction strategy enabled by electron‐rich yolk Cd species both remote from and adjacent to sulfur vacancies is delivered to be ultraselective for the reduction of O2 and •CO2− in situ formed on the shell Bi2S3 composition (hole) by water oxidation and oxidative C–C cleavage of various biomass organic acids, furnishing CO with > 99%

Thiourea-Based Bifunctional Catalysts for Epoxide-Involved Ring-Opening Polymerization of α‑Amino Acid N‑Carboxyanhydrides

open access: yes, 2023
Thiourea-quaternary ammonium salt bifunctional catalysts with both electrophilic and nucleophilic centers were designed in this paper to initiate the ring-opening polymerization (ROP) of α-amino acid N-carboxyanhydrides (NCAs) for the efficient synthesis

Balancing Stealth and Targetability: cCPP‐ and PEG‐Modified Liposomes for the Targeted Delivery of Anti‐HER2 Nanobodies

open access: yesAdvanced Science, EarlyView.
This study addresses the rapid renal clearance of anti‐HER2 nanobodies by developing specialized liposomal carriers. It details the formulation of dual modified liposomes, demonstrating how PEGylation preserves structural integrity and cell‐penetrating peptides enhance cellular interaction.

Unclicking of thioureas: Base catalyzed elimination of anilines and isothiocyanates from thioureas [PDF]

open access: yesTetrahedron, 2019
Bisaromatic thioureas are widely used in e.g. asymmetric organocatalysis and considered to be robust compounds. Herein we show, in strong contrast to common notion, that thioureas dissociate to amines and isothiocyanates in a base catalyzed reaction under mild conditions. This 'unclicking' process can occur in the presence of weak organic bases even at

Axle length- and solvent-controlled construction of (pseudo)[1]rotaxanes from mono-thiourea-functionalised pillar[5]arene derivatives

open access: yes, 2017
A series of thiourea-functionalised pillar[5]arene derivatives 3nm were constructed from a series of mono-amide-functionalised pillar[5]arenes 2n. The formation of their free forms or (pseudo)[1]rotaxane structures were controlled by their axle lengths ...

Highly Reversible Zinc Anode Enabled by a Thiourea‐Derived Protective Layer for Alkaline Zinc Batteries

open access: yesAdvanced Science, EarlyView.
A ZnS/carbon nitride (ZnS/CN) protective coating is constructed on Zn anodes via ultrasonic spray coating, enabling uniform and stable Zn stripping/plating, suppressing dendrite formation, and mitigating parasitic side reactions, resulting in a prolonged cycling lifespan and high reversibility of the Zn anode in alkaline Zn–air batteries. ABSTRACT Zinc‐
