TL;DR: As the popularity of the show proved, the concept of integrating man and machine has long fuelled the imagination and has also been the subject of many other science-fiction movies and shows, including Bionic Woman, Robocop and Inspector Gadget.
Abstract: "We can rebuild him. We have the technology. We have the capability to make the world's first Bionic man." So began each episode of 1970s TV show Six Million Dollar Man, as surgeons attempted to rebuild aeroplane crash victim Steve Austin by fitting him with bionic limbs and eagle-eye vision. As the popularity of the show proved, the concept of integrating man and machine has long fuelled our imagination. It has also been the subject of many other science-fiction movies and shows, including Bionic Woman, Robocop and Inspector Gadget.

TL;DR: In this paper, a thermal process was used to yield organic monolayers covalently attached to the surface through Si-C bonds, and the modified surfaces retained their original photoluminescence (PL) stabilization.
Abstract: Freshly prepared porous silicon (PSi) surfaces have been modified with different organic molecules such as alkenes (1-decene, ethyl undecylenate) and nonconjugated dienes (1,7-octadiene) in a thermal process to yield organic monolayers covalently attached to the surface through Si-C bonds. These monolayers have been characterized using diffuse reflectance infrared Fourier transform, X-ray photoelectron, and Raman spectroscopies, Derivatized surfaces have shown a high stability in boiling aqueous and organic solvents, and in 49% HF and KOH (pH 13) solutions at room temperature. They protect the surface against oxidation when exposed to air at 100% humidity. The high passivation of the surface implies also photoluminescence (PL) stabilization. In fact, the modified surfaces retained their original PL, and the chemical process affected neither the peak position nor the intensity. The PL was preserved even after a steam treatment for several weeks, while the hydrogen-terminated porous layer was completely transformed into a transparent oxide.

TL;DR: In this paper, a particulate product comprising at least one microprojectile is defined as a product consisting of at least two microprojectiles, characterised in that one of them is made of silicon.
Abstract: The invention relates to a particulate product comprising at least one microprojectile; characterised in that the or at least one of the microprojectiles comprises silicon. The invention also relates to devices and components used in the microprojectile implantation of the particulate product to a target of cells or target tissue.
