Bottlenecks‐Breaking in Zinc‐Iodine Batteries Toward Practical Implementation: A Review and Perspective

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Aqueous zinc–iodine batteries (Zn–I2Bs) offer promise for grid storage due to safety and cost advantages yet face critical bottlenecks: severe self‐discharge (polyiodide shuttling and HER), limited energy density, sluggish kinetics, and zinc anode instability.

A Polymethyl Methacrylate Bone Cement With Reduced Stress Concentration

Electron, EarlyView.
PMMA/PLA/CNT composite bone cement with reduced stress concentration. ABSTRACT Polymethyl methacrylate (PMMA) bone cement is the earliest and most widely used in clinical applications. However, PMMA bone cement has high hardness and high modulus, which leads to secondary fracture of adjacent vertebrae. In this study, a PMMA/polylactic acid (PLA)/carbon

Concrete Pavement Mixture Design and Analysis (MDA): An Innovative Approach To Proportioning Concrete Mixtures, TPF-5(205), 2015 [PDF]

, 2015
Mixture proportioning is routinely a matter of using a recipe based on a previously produced concrete, rather than adjusting the proportions based on the needs of the mixture and the locally available materials.

Research on Precise Identification of Rock Strength Based on Bolt Drilling Parameters

Energy Science &Engineering, EarlyView.
Drilling detection test platform. ABSTRACT During roadway excavation, the presence of weak interlayers and fractured rock masses significantly affects roof stability. To achieve timely and effective roadway support, it is crucial to identify and predict different rock types based on drilling signals from roof bolters.
