Can Robotic Arm‐assisted Total Knee Arthroplasty Remain Cost‐effective in Volume‐based Procurement System in China? A Markov Model‐based Study

Orthopaedic Surgery
Objective The volume based procurement (VBP) program in China was initiated in 2022. The cost‐effectiveness of robotic arm assisted total knee arthroplasty is yet uncertain after the initiation of the program.

Conductive Hydrogels for Exogenous Sensing and Cell Fate Control

Advanced Materials, EarlyView.
We engineer electrically conductive hydrogels by combining sulfated glycosaminoglycans with semiconducting polymers. These hydrogels bind bioactive proteins, including growth factors, whose release or retention can be modulated by low‐voltage stimulation. The hydrogels are also integrated as 3D channels in organic electrochemical transistors as part of

Multifunctional Oxadiazole‐Based Polycatenars: A Pathway to Polar Columnar Phases

Advanced Materials Interfaces, EarlyView.
Aromatic core fluorination directs oxadiazole‐based polycatenars into ferroelectric and antiferroelectric columnar phases with supergelation and photo‐responsiveness. ABSTRACT Polar columnar liquid crystals (LCs) offer a promising pathway to nanostructured architectures for next‐generation ferroelectric devices.

Hydrogel‐Based 3D‐Printable Stretchable Pressure Sensor

Advanced Materials Technologies, EarlyView.
We present a carbon‐black‐functionalized double‐network granular hydrogel (DNGH) pressure sensor capable of detecting pressures from 200 Pa, equivalent to a light finger touch, up to 500 kPa. The sensor exhibits signal drifts below 3.5% after 800 cycles and response times around 80 ms. Leveraging this broad sensing range, we 3D print this material into
