A modified nanosphere lithographic method for producing arrays of silanized structures at silicon surfaces is described. Polystyrene (PS) particles (600 nm or 1000 nm in diameter) were self-assembled onto a silicon substrate to form a hexagonal close-packed pattern. The resultant patterned surface was then exposed to a solution of 3-aminopropyltriethoxysilane (APTS), which deposited gradually i...

BACKGROUND Stem cell transplantation has been investigated for repairing damaged tissues in various injury models. Monitoring the safety and fate of transplanted cells using noninvasive methods is important to advance this technique into clinical applications. METHODS In this study, lower-limb ischemia models were generated in nude mice by femoral artery ligation. As negative-contrast agents,...

We report the synthesis and characterization of CuO/Cu2O film supported on nanoporous alumina membranes (NAMs) photocatalytic properties in removal organic pollutant methyl orange (MO). For this purpose, transparent nanostructured were fabricated sequentially modified with APTS ((3-aminopropyl)-trimethoxysilane) EDTAD (ethylenediaminetetraacetic dianhydride) to form a highly functionalized surf...

In this work, silica nanofibers (SNFs) were prepared by an electrospinning method and modified with poly-d-lysine (PDL) or (3-aminopropyl) trimethoxysilane (APTS) making biocompatible and degradable substrates for neuronal growth. The as-prepared SNF, modified SNF-PDL, and SNF-APTS were evaluated using scanning electron microscopy, nitrogen adsorption/desorption isotherms, contact angle measure...

The Abdominal Pressure Twin Sensors (APTS) for Q3 and Q6 dummies are composed of soft polyurethane bladders filled with fluid and equipped with pressure sensors. Implanted within the abdominal insert of child dummies, they can be used to detect abdominal loading due to the belt during frontal collisions. In the present study - which is part of the EC funded CASPER project - two versions of APTS...

As a new type of cyber attacks, advanced persistent threats (APTs) pose a severe threat to modern society. This paper focuses on the assessment of the risk of APTs. Based on a dynamic model characterizing the time evolution of the state of an organization, the organization’s risk is defined as its maximum possible expected loss, and the risk assessment problem is modeled as a constrained optimi...

Magnetic nanoparticles (NPs) of superparamagnetic iron oxide (SPIO) have been explored for different kinds of applications in biomedicine, mechanics, and information. Here, we explored the synthetic SPIO NPs as an adjuvant on antigen cross-presentation ability by enhancing the intracellular delivery of antigens into antigen presenting cells (APCs). Particles with different chemical modification...

The present paper proposes some hints to set up a number of prototypical vowels as acoustic-perceptual targets (APT). APTs are defined using theoretical considerations and the extensive use of an articulatory model for exploring the acoustic and perceptual space. This paper is a revisit of the notion of Cardinal Vowels, which were mainly described in articulatory terms. Our approach avoids the ...
