Excessive wound exudates often cause infection and hinder repair regeneration. It is therefore urgently needed to develop an ideal dressing for pumping the excessive biofluids inhibiting bacterial in healing process. Herein, we demonstrate a facile efficient strategy fabricate unidirectional water-transport antibacterial dressings by embedding macromolecular antimicrobials into multilayer nanof...

The compressive response of polymer matrix fiber reinforced unidirectional composites (PMC’s) is investigated via a combination of experiment and analysis. The study accounts for the nonlinear constitutive response of the polymer matrix material and examines the effect of fiber geometric imperfections, fiber mechanical properties and fiber volume fraction on the measured compressive strength an...

We present an analytical proof of the existence of unidirectional optical Bloch oscillations in a waveguide array system. It is shown that the presence of nonreciprocity in the system allows for a complete normal-mode dephasing in one of the propagation directions, resulting in a unidirectional breakdown in Bloch oscillations. A model system consisting of an array of transversely magnetized asy...

This article presents an experimental and numerical investigation of Mode-I fracture control in aerospace grade unidirectional laminated composites (AS4/914) using the smart material approach. The P1 type macro fiber (MFC) actuators are selected for current research because their higher free strain, high mechanical flexibility, good blocking force. opening mode (Mode-I) interlaminar tests have ...
