This paper presents the design, modeling, and testing of a flexible tactile sensor and its applications. This sensor is made of polymer materials and can detect the 2D surface texture image and contact-force estimation. The sensing mechanism is based on the novel contact deflection effect of a membrane. We measure the deflection of the membrane with measuring the strain in the membrane with emb...

The development of low energy cost membranes to separate He from noble gas mixtures is highly desired. In this work, we studied He purification using recently experimentally realized, two-dimensional stanene (2D Sn) and decorated 2D Sn (SnH and SnF) honeycomb lattices by density functional theory calculations. To increase the permeability of noble gases through pristine 2D Sn at room temperatur...

Guided bone regeneration involves excluding non-osteogenic cells from the surrounding soft tissues and allowing osteogenic originating native to inhabit defect. The aim of this work was fabricate, analyze antibiofilm activity evaluate in vivo biological response poly (lactic-co-glycolic acid) (PLGA) electrospun membranes incorporated with tea tree oil furan-2(5H)-one. Samples were exposed Strep...

Many naturally occurring peptides containing cationic and hydrophobic domains have evolved to interact with mammalian cell membranes and have been incorporated into materials for non-viral gene delivery, cancer therapy or treatment of microbial infections. Their electrostatic attraction to the negatively charged cell surface and hydrophobic interactions with the membrane lipids enable intracell...

Background: Recent results have provided increasing evidence to support involvement of membrane damage in the mechanism of ionizing radiation induced killing of mammalian cells. These findings have stimulated renewed interest in evaluating the damage to membrane as a primary initiator in radiation-induced cell killing especially in apoptotic death. The present study was aimed to gain deeper ins...

In part one of this two-part series on barrier membrane materials, a review of different types of barrier membranes was discussed, along with a breakdown of various features of each barrier material type and a discussion of the clinical applications best suited to each. As discussed in last month’s issue, the restoration of structure and function of bone and peridontium has been aided significa...
