The controllable synthesis of monodisperse mesoporous silica microspheres with unique physicochemical properties is becoming increasingly important for a variety of applications such as catalysts, chromatography, drug delivery and sensors. Here, we report a facile microfluidic-assisted sol-gel method for the preparation of silica microspheres with precisely controlled properties such as the size of the microspheres, the surface morphology, porosity and stiffness. All these properties can be manipulated by changing specific synthesis parameters, such as changing the microfluidic channels to tune the size of the microdroplets (tens to hundreds of microns), changing the contents of the precursor solution to manipulate the surface morphology (wrinkled to smooth surface) and changing the gelation/annealing conditions to tune the porosity (surface area up to 1021 m g) and stiffness of the microspheres (elastic modulus tunable from 0.

Biomolecules usually adopt ubiquitous circular structures which are important for their functionality. Based on three-dimensional Langevin dynamics simulations, we investigate the conformational change of a polymer confined in a spherical cavity. Both passive and active polymers with either homogeneous or heterogeneous stiffness are analyzed in a comparative manner.

Upper limb lymphedema is the most common complication after breast cancer therapy. Suddenly disturbed lymphatic transport in the affected arm causes tissue fluid accumulation in tissue spaces, limb enlargement, and secondary changes in tissue. Early compression therapy is necessary.

In bioneuronal systems, the synergistic interaction between mechanosensitive piezo channels and neuronal synapses can convert and transmit pressure signals into complex temporal plastic pulses with excitatory and inhibitory features. However, existing artificial tactile neuromorphic systems struggle to replicate the elaborate temporal plasticity observed between excitatory and inhibitory features in biological systems, which is critical for the biomimetic processing and memorizing of tactile information. Here we demonstrate a mechano-gated iontronic piezomemristor with programmable temporal-tactile plasticity.
