Frictional Properties of DLC films in Plane Contact due to Reciprocal Micro-Sliding

open access: yesTribology Online, 2009
The objective of this research is to investigate the frictional behavior of a-C:H coating in plane contact by using reciprocating micro-sliding test under controlled relative humidity. The friction tests were conducted at various relative humidities (RH)

Pathological Mechanism‐Inspired Biomimetic Nano‐Senotherapy for Reversing Experimental Atherosclerosis in ApoE−/− Mice

open access: yesAdvanced Science, EarlyView.
The biomimetic self‐assembly nanomedicine reversing atherosclerosis via senotherapy strategy. ABSTRACT The greatest challenge in atherosclerosis (AS) management lies in achieving lesion reversal, not merely slowing progression. Senescent cell accumulation—driven by continuous generation and apoptotic resistance—perpetuates plaque pathology and ...
