Increasing Saw Resistance to Wear by Sharpening Interruption Abrasive Circles
Науковий вісник НЛТУ України, 2017 The existing method of sharpening steel saws with solid abrasive wheels is of low productivity and doesn't provide high level of wear resistance. Abrasive wheels with intermittent sharpening surface may be used to avoid this drawback.

Rubber Wear: History, Mechanisms, and Perspectives [PDF]
arXivThis paper presents a comprehensive review of wear mechanisms, with a primary focus on rubber wear under sliding conditions. Beginning with classical wear theories, including the Archard and Rabinowicz models, we analyze their applicability to both metals and elastomers and discuss extensions relevant to elastic contact and multiscale surface roughness.

Robust Stick‐and‐Play Photothermal Icephobic Film with Bioinspired Insulation Cells
Advanced Science, EarlyView.Inspired by the seed‐and‐framework structure of lotus seedpods, a photothermal anti‐icing film is developed by embedding thermal‐management hydrophobic microcells (THMC) into PDMS. Combining photothermal/insulating synergy and hydrophobic microcells, it achieves heat accumulation, surface adhesion, and robust anti‐icing under weak light, enabling ...
