A Piezo‐Mimetic Ionic Hydrogel Harnessing Joint Motion for Cartilage Repair

Advanced Science, EarlyView.
A piezo‐mimetic ionic hydrogel converts mechanical deformation into bioactive ionic currents via stress‐induced asymmetric ion migration. Coupled with sustained Mg2+ release, this mechano‐electrochemical platform bridges mechanical loading and cellular signaling, enabling load‐adaptive stimulation and enhanced cartilage regeneration. ABSTRACT Articular

Topologically Structured PLLA Fibers With Stress Concentration Effects for Health Monitoring

Advanced Science, EarlyView.
In this study, a multi‐path strategy was developed to enhance the piezoelectric properties of PLLA fibers through the stress concentration effect. The optimized devices generate piezoelectric output up to 14 times that of pure PLLA fibers. This piezoelectric enhancement strategy offers a new approach for high‐performance piezoelectric devices, with ...

Rheological behavior of hyperbranched polymers

, 2013
Hyperbranched polymers represent intriguing class of dendritic polymers, which show remarkable, unique and different chemical and physical properties compared to their linear counterparts, as a result of their complex, three-dimensional structure, presence of a large number of end functional groups and low degree of entanglement.

Rheological Behavior Patterns in Artificial Tears

Optometry and Vision Science, 2022
SIGNIFICANCE Rheological patterns were objectively calculated considering the first and last viscosity, besides the difference of viscosity with a specific shear rate. Shear thinning, shear thickening, thixotropic, and Newtonian behavior patterns were found.

Rheological behavior and the SPF of sunscreens

International Journal of Pharmaceutics, 2003
Due to a large variety of sunscreens, it is important to study among other things, the effect of the vehicle on the thickness and uniformity of sunscreen films. In this study, we determined the physical stability of five sunscreens SPF 15 (FA to FG), containing or not PVP/eicosene crosspolymer (PVP/EC), and two different self-emulsifying bases (SEB ...
