Porous silicon nanoparticles have been established as excellent candidates for medical applications as drug delivery devices, due to their excellent biocompatibility, biodegradability, and high surface area. The simple fabrication method by electrochemical anodization of silicon and its photoluminescent properties are some of the merits that have contributed to the increasing interest given to porous silicon. This paper presents the methods of fabrication, which can be customized to control the pore size, various chemical treatments used for the modification of silicon surfaces, and the characterization and pore morphology of silicon structures. Different approaches used for drug loading and the variety of coatings used for the controlled released are revised. The monitoring of the toxicity of silicon degradation products and the in vivo release of a drug in a specific site are described taking into account its significance on medical applications, specifically on cancer therapy.

A memory device and related methods are described. The memory device includes a plurality of cells, each cell including a MOSFET having a source coupled to a first end of a channel, a drain coupled to a second end of the channel, a gate formed on a gate insulator and extending from the source to the drain and a plurality of conductive islands, each surrounded by an insulator, formed in the channel. The islands have a maximum dimension of three nanometers. The surrounding insulator has a thickness of between five and twenty nanometers. Each island and surrounding insulator is formed in a pore extending into the channel. As a result, the memory cells are able to provide consistent, externally observable changes in response to the presence or absence of a single electron on the island.

Synthetic Aperture Radar (SAR) is traditionally used in the identification, mapping, and analysis of petroleum slicks, regardless of their origin. On SAR images, oil slicks appear as dark patches that contrast with the brightness of the surrounding sea surface. This distinction allows for automated detection algorithms to be designed using computer vision methods for objective oil slick identification. Nevertheless, efficient interpretation of the SAR imagery by statistical analysis can be diminished due to the speckle effect present on SAR images, a granular artefact associated with the coherent nature of SAR, which visually degrades the image quality. In this study, a quantitative and qualitative assessment of common SAR image despeckling methods is presented, analyzing their performance when applied to images containing natural oil slicks. The assessment is performed on Copernicus Sentinel-1 images acquired with various temporal and environmental conditions. The assessment covers a diverse area of filters that employ Bayesian and non-linear statistics in the spatial, transform and wavelet domains, focusing on their demonstrated performance and capabilities for edge and texture retention. In summary, the results reveal that filters using local statistics in the spatial domain produce consistent desired effects. The novel SAR-BM3D algorithm can be used effectively, albeit with a higher computational demand.
