This paper presents the fabrication and characterization of a flexible gas sensor based on TiO2 nanotubes membrane, onto which array interdigitated gold electrodes in one side and a common heater in the backside were obtained using conventional microfabrication techniques. This was used to detect hydrogen sulphide within a concentration range of 6–38 ppm. The response to low concentrations of H...

The integration of onsite, decentralized, and satellite wastewater treatment systems into existing urban water infrastructure is an attractive option for recovering water and nutrients locally for multi-purpose reuse. To facilitate wastewater treatment and reuse, tailored to local needs, a hybrid membrane treatment process is proposed that couples sequencing batch reactors with a membrane biore...

Second-order vestibular neurons (2°VN) are the central element for the transformation of body motion-related sensory signals into extraocular motor commands for retinal image stabilization during locomotion. The wide range of motion dynamics necessitates sensory signal transformation in parallel, frequency-tuned channels. Accordingly, in various vertebrates, 2°VN have been shown to form differe...

Herein we report for the first time fabrication of reverse bumpy ball (RBB)-type-nanoreactor-based flexible peroxidase-mimic membrane reactors (MRs). The RBB-type nanoreactors with gold nanoparticles embedded in the inner walls of carbon shells were loaded on nylon membranes through a facile filtration approach. The as-prepared flexible catalytic membrane was studied as a peroxidase-mimic MR. I...

This paper presents an implementation of the second-order accurate immersed interface method to simulate the motion of the flexible elastic membrane immersed in two viscous incompressible fluids with different viscosities, which further develops the work reported in Tan et al. [Z.-J. Tan, D.V. Le, K.M. Lim, B.C. Khoo, An Immersed Interface Method for the Incompressible Navier–Stokes Equations w...

Intrinsically disordered proteins (IDPs) that lack stable conformations and are highly flexible have attracted the attention of biologists. Therefore, the development of a systematic method to identify polypeptide regions that are unstructured in solution is important. We have designed an "indirect/reflected" detection system for evaluating the physicochemical properties of IDPs using nuclear m...

This paper describes the development of a polyimide/SU-8 catheter-tip MEMS gauge pressure sensor. Finite element analysis was used to investigate critical parameters, impacting on the device design and sensing characteristics. The sensing element of the device was fabricated by polyimide-based micromachining on a flexible membrane, using embedded thin-film metallic wires as piezoresistive eleme...

Voltage-gated sodium selective ion channel Na(V)1.5 is expressed in the heart and the gastrointestinal tract, which are mechanically active organs. Na(V)1.5 is mechanosensitive at stimuli that gate other mechanosensitive ion channels. Local anesthetic and antiarrhythmic drugs act upon Na(V)1.5 to modulate activity by multiple mechanisms. This study examined whether Na(V)1.5 mechanosensitivity i...

Local search is currently one of the most used methods for finding solution in real-life problems. In this paper we present an implementation of local search with Membrane Computing techniques applied to the N-queens problem as a case study. A CLIPS program inspired in the Membrane Computing design has been implemented and several experiments have been performed.
