Programmable Porosity in Polymers via Microfluidic Templating and 3D Printing

Small Methods, EarlyView.
Fluid templating is a powerful way to produce porous polymers. Microfluidic technologies enable fine control over the dimension and packing of bubbles and droplets. Combined with additive manufacturing, microfluidic templating enables the creation of polymeric functionally graded porous materials in which both porosity and three‐dimensional geometry ...

Influences of Cleanliness, Carbide Size, Hardness, and Residual Stresses on Long‐Life Fatigue Strength and Crack‐Initiation Mechanisms in Carbide‐Rich Cold‐Work Tool Steels Using Normalized S–N Curves and Database‐Driven Validation of Murakami's √Area Model

steel research international, EarlyView.
Rotating‐bending fatigue tests on AISI D2 and AISI A11 quantify how cleanliness, carbide structure, hardness, and fabrication‐induced compressive residual stresses govern long‐life fatigue at NG = 107 cycles. Statistical fracture‐surface analysis and extreme‐value √area statistics link crack‐initiators to LLF strength.

Study on the Power‐Frequency Arc Extinction Characteristics of Semi‐Closed Short‐Gap Device

High Voltage, EarlyView.
ABSTRACT Multi‐chamber arc‐extinguishing devices have a simple structure and excellent arc‐extinguishing performance; thus, they have attracted considerable attention as lightning protection devices. However, the structural parameters of different models of the aforementioned devices vary, leading to inconsistent protection levels; therefore, the arc ...

Large‐Scale Applications of Plasma Technologies: Progresses and Challenges

High Voltage, EarlyView.
ABSTRACT Plasma technologies convert electrical power into energetic electrons, ions, reactive species, radiation and heat, thereby breaking through the bottleneck of purely thermal or chemical routes and bringing impressive changes to our world. This roadmap reviews the progress and challenges of plasma technologies from a large‐scale and application ...

Study on Raindrop Dynamic Behaviour and Its Impact on Insulator Flashover Characteristics Under Airflow Synergy

High Voltage, EarlyView.
ABSTRACT The synergistic effect of airflow on rainfall behaviour significantly impacts the flashover probability of insulators. This study combines experiments and simulations to investigate the influence of raindrop dynamic behaviour, shed structures and rainfall conditions on flashover characteristics under airflow conditions.
