Adaptive Hydrogels With Spatiotemporal Stiffening Using pH‐Modulating Enzymes

Advanced Functional Materials, EarlyView.
The chemomechanical coupling in an adaptive hydrogel is studied to further the development of adaptive hydrogels. This coupling is achieved by embedding a pH‐modulating enzyme in a pH‐responsive hydrogel. The enzymatic reaction can be triggered locally, which generates a pH‐decreasing wave throughout the system, increasing the crosslinking density and ...

Use of passive safety supporting structures [PDF]

E3S Web of Conferences, 2019
Road safety issues have been raised for many years in subsequent national and EU documents. An example of a Polish document is the National Road Safety Program for 2013-2020 [1]. The priorities and measures adopted in the document [1] relate mainly to the environment and road furnishings making up the so-called passive road safety.

Enhanced Li‐Ion Battery Performance with Hybrid MXene/GnR Electrodes: Heterojunctions and Engineered Architectures Supported by DFT Mechanistic Studies for Improved Rate Performance, Stability & Capacity

Advanced Functional Materials, EarlyView.
Lithium‐ion batteries (LIBs) remain central to energy storage but suffer from slow ion transport and degradation. Here, we present a binder‐free Ti3C2Tx MXene/GnR hybrid electrode with a porous 3D architecture formed via freeze casting. The structure enhances conductivity, ion transport, and stability, delivering 401 mAh/g, ∼97% efficiency, and 92 ...

Numerical simulation study on oxygen transport in the natural circulation process of liquid lead–bismuth eutectic

International Journal of Advanced Nuclear Reactor Design and Technology
The lead-cooled fast reactor uses liquid lead–bismuth eutectic (LBE) as the coolant. In accident conditions, a passive cooling system is used to remove the heat from the reactor core to avoid meltdown. Therefore, the natural circulation ability of liquid

Single‐ and Dual‐Atom Configurations in Atomically Dispersed Catalysts for Lithium–Sulfur Batteries

Advanced Functional Materials, EarlyView.
Single‐atom and dual‐atom‐based atomically dispersed catalysts (ADCs) effectively address the shuttle effect and sluggish redox kinetics in Li–S batteries. With nearly 100% atomic utilization and tunable coordination environments, ADCs enhance LiPSs adsorption, lower conversion barriers, and accelerate sulfur redox reactions.

A CFD SSTk−ω−kθ−εθ four parameter heat transfer turbulence model for the 19-pin fuel assembly in LBE cooled reactors

Nuclear Engineering and Technology
Liquid lead-bismuth eutectic (LBE) alloy exhibits excellent thermo-hydraulic properties and chemical inertness as a coolant for fast reactors. Unlike conventional fluids such as water and air, LBE has a lower Prandtl number (Pr), and its local turbulent ...
