Materials for the treatment of cancer have been studied comprehensively over the past few decades. Among the various kinds of biomaterials, polymer-based nanomaterials represent one of the most interesting research directions in nanomedicine because their controlled synthesis and tailored designs make it possible to obtain nanostructures with biomimetic features and outstanding biocompatibility.

A novel design for the classical microfluidic device known as T-junction is proposed with the purpose of obtaining a simultaneous measurement of the in-plane velocity components in two orthogonal planes. A crucial feature of the proposed configuration is that all three velocity components are available along the intersection of the two planes. A dedicated optical set-up is developed to convey the two simultaneous views from the orthogonal planes into the sensor of a single camera, where a compound image is formed showing on either half one of the two views.

In this work we discuss the degradation chemistry on carbon-free electrodes of two ether based electrolytes for Li-O2 batteries, i.e. tetraethylene glycol dimethyl ether (TEGDME) and dimethoxy ethane (DME) with lithium trifluoromethane sulfonate (LiTfO) as salt. To this aim we developed an all-metallic positive electrode by electrodeposition of a gold dendritic film on a nickel foam (Au@Ni).

The thermal behavior and pyrolytic kinetic analysis of main waste polymers (polypropylene (PP), polyethylene
film (PE), poly(ethylene terephthalate) (PET), polystyrene (PS)) and three synthetic mixtures representing commingled postconsumer
plastics wastes (CPCPWs) output from material recovery facilities were studied. Thermogravimetry (TG) pyrolysis
experiments revealed that the thermal degradation of single polymers and the synthetic mixture enriched in PP occurred in

Sensors using surface plasmon resonance (SPR) are established as themethod of choice in label-free optical biosensing.
Their sensitivity for small refractive index changes at the surface originates from the enhanced evanescent
field at the surface of a thin metal layer. However, the small number of well-suited metals (Ag, Au) with
fixed optical constants limits a further refinement of the SPR performance in terms of dispersion and resonance
width. An alternative can be found in Bloch SurfaceWaves (BSW) sustained at specially designed dielectricmultilayer

We report on the use of an optical sensing platform based on Bloch surface waves sustained by one-dimensional photonic crystals as a novel optical tool to probe in real time the fluid flow at a boundarywall of a microfluidic channel under dynamic conditions. Understanding how fluid flow interacts withwall surfaces is crucial for a broad range of biological processes and engineering applications, such as sur-face wave biosensing. The proposed platform provides nanometric resolution with respect to the distancefrom the boundary wall sensor’s surface.

The development of wide-area cryogenic light detectors with baseline energy resolution lower than 20 eV RMS is essential for next generation bolometric experiments searching for rare interactions. Indeed the simultaneous readout of the light and heat signals will enable background suppression through particle identification. Because of their excellent intrinsic energy resolution, as well as their well-established reproducibility, kinetic inductance detectors (KIDs) are good candidates for the development of next generation light detectors.

The integration of systems for real-time monitoring of DNA amplification reactions is rather limited, because the heating system, the temperature control and the detection system are usually realized with separate modules. In this work, a lab-on-a-chip system for real-time monitoring of the multiple displacement amplification reaction (MDA) is presented. The amplification and detection unit consists of a system-on-glass (SoG) coupled to a microfluidic chip.

Pure nickel coatings were directly plated onto steel by using an electroless plating process. The effect of different synthesis strategies on the morphological surface was investigated and the study of growth mechanisms has provided useful information about the surface properties of coating. In this paper, several plating parameters (pH, temperature, solution composition and the ratio between the sample surface area and the volume of solution) were investigated by studying their influence on the plating rate. High thickness (30 μm) coatings were obtained after 2 h of plating at 85 °C.
