First-place finish : imparting fine surface finishes when micromilling [PDF]

open access: yes, 2010
There are several key milling practices that help impart fine surface finishes in micromilling. They include running at ultrahigh spindle speeds, carefully monitoring chip load, employing climb milling when possible and using CAM software to develop ...

A Compact, High‐Performance, and Deformation‐Resilient Trielectrode Electrostatic Soft Pump for Soft Robotics

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Existing soft pumps often require tradeoffs between performance and compatibility with soft robotic systems. The proposed trielectrode electrostatic soft pump addresses these limitations through an innovative driving mechanism. Its design, which includes a trielectrode configuration and the use of compliant materials, improves operational efficiency ...

Performance Investigation of Eco‐Friendly Refrigerant Mixtures as an Alternative to R134a in Vapour‐Compression Refrigeration System

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The growing impacts of climate change and energy scarcity demand environmentally sustainable refrigeration solutions. This study investigates eco‐friendly refrigerants (R152a, R290 and R600a) and their optimized ternary mixture as alternatives to R134a. Four blend compositions were analysed using experimental testing and REFPROP 10.0 modelling

Preliminary insights on high‐fidelity embalming solutions for surgical skills training—An evaluation using the McMaster Embalming Scale and mechanical tests

open access: yesAnatomical Sciences Education, EarlyView.
Abstract Simulation‐based training is critical for surgical skill acquisition and typically uses soft‐preserved body donors, as they represent high‐fidelity models (vs. hard‐fixed donors) with prolonged periods of preservation (vs. unembalmed donors).

Dynamic cracking properties and generating conditions of coal under rapid gas release

open access: yesDeep Underground Science and Engineering, EarlyView.
Gas release tests revealed that crack initiation and propagation are jointly controlled by initial crack length, residual strength, and gas release velocity. A new outburst risk coefficient was thus developed from a fracture mechanics perspective, offering a novel predictive approach.
