Design principles for vitrimers: Linking dynamic covalent chemistry, network architecture, and engineering performance

Bulletin of the Korean Chemical Society, EarlyView.
This review examines vitrimer performance from a broader perspective, considering not only dynamic covalent chemistry but also molecular structure, network architecture, and rheological behavior. These factors are discussed in relation to service and processing windows, reprocessing, repair, and engineering applications, providing a multiscale ...

A Homoleptic Copper(I) Acetylene Complex

Chemistry – A European Journal, EarlyView.
Ligand substitution of weakly coordinated N2 in [(N2)Cu{Al(ORF)4}] (RF = C(CF3)3) leads to the homoleptic acetylene complex [Cu(C2H2)3]+[Al(ORF)4]−, which was characterized by single crystal x‐ray diffraction, NMR, and Raman spectroscopy, as well as by extensive quantum chemical calculations. ABSTRACT We report the synthesis and characterization of the

Influence of Contact Pressure on Performance and Crossover in Zero‐Gap Alkaline Water Electrolysis

Chemie Ingenieur Technik, EarlyView.
Cell performance and product gas quality in zero‐gap alkaline water electrolysis are influenced by the mechanical contact pressure in the electrode area. With a newly developed contact‐pressure cell, it was found that the influence of contact pressure can vary drastically, depending on the cell configuration, electrode type, and diaphragm.

Numerical simulation study on the characteristics and propagation attenuation of vibration signals in freezing pipe fracture

Deep Underground Science and Engineering, EarlyView.
This research study employs analysis system (ANSYS) fluid–structure interaction simulations to investigate the generation and attenuation of vibration signals resulting from freezing pipe fractures in artificial ground freezing projects. By evaluating key variables—including frozen soil elastic modulus, brine inlet pressure, and external pipe pressure ...

Bio‐based tannin‐loaded layered double hydroxides in epoxy coatings for smart corrosion protection of steel in underground infrastructure

Deep Underground Science and Engineering, EarlyView.
This study presents a sustainable smart‐coating strategy for protecting underground steel infrastructures from chloride‐induced corrosion. Zinc‐aluminum layered double hydroxides (LDHs) and tannin‐loaded LDHs (LDH–TA) were incorporated into an epoxy matrix to provide both enhanced barrier properties and active, pH‐responsive inhibition.

Steel segment–anchor bolt (cable) structure for TBM tunnels under extremely intense rockburst conditions: Design method and field application

Deep Underground Science and Engineering, EarlyView.
The graphical abstract presents a steel segment–anchorage support system for open TBM tunnels under extremely intense rockburst conditions. The steel segment resists dynamic impact, while the anchorage structure restrains segment deformation and transfers loads into the rock.
