Spindle thermal drift measurement using the laser ball bar

Precision Engineering, 1996
Thermally induced errors are major contributors to the overall accuracy of machine tools. An important component of thermally induced errors is the error associated with spindle thermal drifts. In this paper, a novel method is developed to measure spindle thermal drifts in machine tools using a laser ball bar (LBB) as the calibration instrument.

Nanofiber‐Supported Decellularized Matrix Membrane Creates a Biomimetic Biochemical and Biophysical Niche for Intestinal Organoid Epithelium

Advanced Healthcare Materials, EarlyView.
A nanofiber‐supported decellularized extracellular matrix (NaDE) membrane recreates key biochemical and mechanical features of native intestinal tissue. This platform enables the formation of a more physiologically relevant intestinal epithelium, enhancing stem cell maintenance and promoting diverse cell differentiation.

Multidimensional Cellular Micro‐Compartments to Model Invasive Lobular Carcinoma Dormancy

Advanced Healthcare Materials, EarlyView.
Invasive lobular carcinoma (ILC) is an understudied subtype of breast cancer that is susceptible to late recurrences. In this study, micro‐compartmentalization techniques spanning multiple dimensions, including 2D, pseudo‐3D, and 3D, are integrated to uncover the mechanisms underlying ILC dormancy, revealing the central role of p27Kip1.

Tuning Amorphous‐Crystalline Catalytic Interfaces by Mechanochemistry: Cu‐Based Metallic Glasses Coupled with Ceria for CO Oxidation

Advanced Materials, EarlyView.
Ball‐milling Cu‐based metallic glasses with ceria creates a unique nanostructure where metallic glass particles are wrapped by CeO2 nanoparticles. The intimate integration triggers copper state reorganization during reaction and aging, boosting CO oxidation and COPrOx activity.
