Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy
Advanced Materials, EarlyView.Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Hard machining of agricultural machines parts
Research in Agricultural Engineering, 2013 For the renovation and/or improvement of the surface properties of machine elements, hard facing is often used. Hard structures obtained in layers or by heat treatment achieve a hardness of up to 68 hardness (HRC) or even more.

Effect of Composition on Grain‐Boundary Chemistry and Fracture Behavior in High‐Entropy Carbides
Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.ABSTRACT High‐entropy carbides (HECs) are often treated as a single material class defined by configurational entropy; however, their properties are governed by composition‐specific defects and grain‐boundary chemistry. This study demonstrates that substituting a single element can qualitatively change grain‐boundary structure and fracture behavior in ...

JSME International Journal Series C, 2006 In this paper, we describe the formation mechanism of a finished surface in ultrahigh-speed grinding under a peripheral wheel speed higher than 200m/s. Grinding experiments using a grinding machine tool equipped with an active magnetic bearing spindle have been conducted over a range of grinding speeds from 60 to 300m/s.
