Feasibility and Limitations of the Advanced Replica Process for Bioactive Glasses

Advanced Engineering Materials, EarlyView.
Periodic 3D‐printed Kelvin‐cell templates enable a controlled advanced replica process for fabricating highly porous glass lattices. Across P45K9, 45S5, and 13–93, material‐dependent differences in coating, burnout, and shrinkage lead to distinct strut morphologies, while comparable final porosities of 83%–88% are retained.

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

Advanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

Seismic Damage and Track Irregularity Analysis of High-Speed Railway Track–Bridge Systems Under Near-Fault Earthquakes and CA Mortar Layer Void

Buildings
High-speed railway track–bridge systems (HSRTBSs) in near-fault high-seismicity regions face combined threats from pulse-type seismic excitations, vertical earthquake components and track defects, which may trigger structural damage and deterioration of ...

Chitin‐Derived Carbon‐Metal Functional Materials

Advanced Functional Materials, EarlyView.
Functional carbon materials are synthesized from combination of biopolymer (chitin) and iron precursors. The resultant material exhibits superior surface area and adsorptive properties compared to carbon materials synthesized directly from pure chitin.

Capsule controlled release of crystallisation inhibitors in mortars

Materials & Design
Crystallisation inhibitors, such as sodium ferrocyanide (NaFeCN), are highly effective in mitigating NaCl-induced weathering in lime-based mortars; however, direct addition of NaFeCN in lime-mortars increases its susceptibility to leaching and rapid ...

Analysis of autogenous shrinkage and pore structure of cement mortar with low-activity slag as internal curing material

Shuili Shuiyun Gongcheng Xuebao, 2022
The pre-saturated low-activity slag was used as a partial replacement of sand for internal curing materials. The mechanical properties and autogenous shrinkage of internal curing mortar with different low-activity slag contents were studied.
