(a) The outstanding lubricative properties of natural articular cartilage arise from a composite coating composed of HA, lubricin, and phospholipids at its surface. Notably, lubricin facilitates the enrichment of synovial HA onto cartilage surfaces, and HA complexes with phospholipids, a key component to maintain extremely low friction under high ...

A steric‐hindrance molecular engineering strategy uses dimethyl maleate (DMM) to convert poly(1,4‐butanediol) bis(4‐aminobenzoate) (PBDAB) into a precursor with reduced reactivity via Michael addition, thereby retarding the curing process to form a transparent, ultraflexible, and self‐healable secondary‑amine polyurea (PuSA) with a crosslinked network.

Derivation of a Barton standard JRC characterization formula considering sampling interval
ObjectivesTo achieve accurate characterization of the joint roughness coefficient (JRC), this study employs the root mean square of the first derivative (Z₂), a statistical roughness parameter, to quantify the two-dimensional joint profile roughness ...

A rotational energy harvesting device that successfully reconciles high power density with mechanical durability through a hybrid sliding‐and‐bouncing kinematic mechanism is reported. The success reported in our paper includes addressing a dilemma where enhanced electrical output comes at the cost of increased friction and wear, limiting the practical ...

Friction and wear of the Durham finger prosthesis [PDF]
Rheumatoid arthritis of the hand can cause deformities that may severally impair hand function. Surgical procedures including total joint replacement have been developed over the last thirty years to treat patients with metacarpophalangeal deformity. The

A novel synergistic strategy by employing dual functional sulfur‐containing additives of lithium sulfide (Li2S) and its oxidation product lithium sulfate (Li2SO4) was proposed. Li2SO4 absorbs the solvent molecules to direct the formation of a uniform, Li2O‐rich, and adaptive interphase, which accommodates volume expansion and suppresses parasitic ...

Silicon hot‐carrier photodetectors offer a CMOS‐compatible pathway for SWIR detection but suffer from intrinsically low quantum efficiency. Here, we introduce a quasi‐generalized antireflection coating (QARC) that universally enhances optical absorption and quantum efficiency, enabling the first CMOS‐compatible SWIR imaging with silicon hot‐carrier ...
