Dry sliding friction and wear response of WC-Co hardmetal pairs in linearly reciprocating and rotating contact [PDF]

, 2011
This paper presents an experimental evaluation of friction and wear properties of WC-Co cemented carbides. A comparison is made between unlubricated rotating and linearly reciprocating pin-onplate sliding pairs. The plate specimens were WC-10wt%Co grades

Breaking the 2‐nm Barrier in Hard Disk Drives Using Monolayer Amorphous Carbon Overcoats

Advanced Materials, EarlyView.
The rapid growth of AI has increased demand for large‐scale data storage, making HDDs indispensable in data centers. Increasing areal storage density is crucial, but limited by the traditional carbon overcoats (COC). Monolayer amorphous carbon (MAC) offers a superior alternative.

Stiff to Soft: A Protein‐Based Buffer Layer for Improving the Long‐Term Performance of Microneedle Sensors

Advanced Materials, EarlyView.
To enhance stability and long‐term biocompatibility of wearable microneedle sensors, a crosslinking‐recombination bovine serum albumin material is used as a buffer layer coated on microneedle sensors. This coating layer possesses a unique stiff‐to‐soft transition function balancing the mechanical stiffness desired for puncturing and soft required for ...
