Solidification of fluidic ionic liquids into porous materials yields porous ionic networks that combine the unique characteristics of ionic liquids with the common features of polymers and porous materials. This minireview reports the most recent advances in the design of porous ionic liquids. A summary of the synthesis of ordered and disordered porous ionic liquid-based nanoparticles or membra...

Biomaterials include bioceramics, biometals, biopolymers and biocomposites and they play important roles in the replacement and regeneration of human tissues. However, dense bioceramics and dense biometals pose the problem of stress shielding due to their high Young’s moduli compared to those of bones. On the other hand, porous biomaterials exhibit the potential of bone ingrowth, which will dep...

There have been many reports regarding visible luminescence and light emission at 1.54 mm, at room temperature, from porous silicon and from Er-doped porous silicon, respectively. Described is a different approach, based on Raman scattering in porous silicon, to generate radiation at 1.54 mm. Preliminary experimental results regarding Raman emission in porous silicon samples at 1.54 mm are also...

A Computational model to solve the coupled transport equations with chemical reaction and phase change for a liquid droplet between two approaching porous or non-porous surfaces, is developed. The model is general therefore it can be applied to toxic chemicals (contact hazard), drug delivery through porous organs and membranes, combustion processes within porous material, and liquid movements i...

Coral-like porous Si was fabricated through the dealloying of a laser remelted as-cast AlSi12 alloy(Al-12 wt % Si). The porous Si was composed of interconnected micro-sized Si dendrites and micro/nanopores, and compared to flaky Si, which is fabricated by direct dealloying of the as-cast AlSi12 alloy. The structure of the porous Si was attributed to the dendritic solidification microstructure f...

while blunt trauma of the head and neck are a common pattern of injury, significant problems related to the prompt diagnosis and optimal management of traumatic artery injuries have been reported in the literature. while patients with major artery injuries might develop hemorrhagic shock very rapidly, patients with blunt cerebrovascular injuries (bcvi) can present asymptomatic, but complication...

Novel fabrication techniques and polymer systems are being explored to enable mass production of low cost microfluidic devices. In this contribution we discuss a new fabrication scheme for making microfluidic devices containing porous polymer components in situ. Contact lithography, a living radical photopolymer (LRPP) system and salt leaching were used to fabricate multilayer microfluidic devi...
