A adhesive-less bonding techniqe, by which a poly-olefine film can be firmly attached to an inorganic substrate such as glass at a low temperature blow glass-transition temperature, is provided. The bonding is acheived through photochemical activation of organic surfaces using vacuum ultra-violet light and modification of the inorganic surface with a self-assembled monolayer.
Electrons are accelerated by changing temperature of a pyroelectric crystal in low-vacuum. We realized an apparatus to detect visible light emitted by bombarding the electrons on samples containing rare earth elements. We succeeded in detecting tens of ppm of rare earth elements in mineral ore with the apparatus.
We propose a convenient process for the synthesis of metallic nanowire nonwoven clothes (MNNC) on a massive scale by the liquid reduction process. We also introduce the application of MNNC to a light-weight and binder-free electrode for high-rate and good-cycle batteries.
We have found that the memory effect which is the major shortcoming of nickel-metal-hydride battery and nickel-cadmium battery comes from local cell reaction between the cathode material (β-NiOOH) and current collector. We also invented the electrode structure which can restrain the memory effect.
The invention is a method concerning an rare earth-free inorganic thin film possessing both transparency and photoluminescence property. By the sol-gel method and the conventional melt quenching method, it is difficult to prepare a thin film showing emission property with high efficiency. Not only transparent large area device, but also various shape device possessing emitting property can be prepared by the invention.
Diffusion of polyiodide ions from aqueous solution into polymeric materials intorduces "secondary doping" with "a posteriori" inorganic ions and, on occasion, hybrid composite brought by inner precipitation. Such process is applied for metal plating on surface of polymeric matrix with arbitrary shape and size.
We have developed an electrodeposition method for the formation of smooth, bright aluminum coatings using an inexpensive organic solvent. We have also devised a new process for the formation of porous aluminum layers.
