The embodiments of the present disclosure relate to a method, system and composition producing a magnetic carbon nanomaterial product that may comprise carbon nanotubes (CNTs) at least some of which are magnetic CNTs (mCNTs). The method and apparatus employ carbon dioxide (CO.sub.2) as a reactant in an electrolysis reaction in order to make mCNTs. In some embodiments of the present disclosure, a magnetic additive component is included as a reactant in the method and as a portion of one or more components in the system or composition to facilitate a magnetic material addition process, a carbide nucleation process or both during the electrosynthesis reaction for making magnetic carbon nanomaterials.

The present disclosure relates to mesoporous silica wrapped nanoparticle composite nanomaterial, preparation method thereof, and use thereof. In the present disclosure, a nanoparticle is dispersed in an aqueous ethanol solution. Then, ammonia water is added to adjust the pH. After that, cetyltrimethylammonium bromide in an aqueous ethanol solution is added dropwise, and ultrasound is continued, before tetraethyl orthosilicate is added dropwise. The mixture is purified to produce a composite nanomaterial that is stable, controllable, and consistent in size; the shell of the composite nanomaterial is mesoporous silica, the core of the composite nanomaterial is a nanoparticle. Dual-core or triple-core nanoparticles of different kinds/functions can be wrapped into a single mesoporous silica shell to achieve multi-core wrapping. The method is universal and may be used to wrap various nanometers. The preparation procedure is environmentally friendly, efficient, and may be carried out at room temperature.

A thin-film deposition system deposits a thin-film on a wafer. A radiation source irradiates the wafer with excitation light. An emissions sensor detects an emission spectrum from the wafer responsive to the excitation light. A machine learning based analysis model analyzes the spectrum and detects contamination of the thin-film based on the spectrum.

A field effect transistor and a sensor using the field effect transistor is provided. The field effect transistor can be manufactured so as to have uniform properties by simple steps at low costs, and can stably detect, when used as a sensor, a very small amount of analyte with a high sensitivity while the properties are hardly deteriorated. A channel of the field effect transistor is constituted by a single-walled carbon nanotube thin film that is grown, by a chemical vapor deposition method, using particles of a nonmetallic material as growth nuclei, the nonmetallic material containing 500 mass ppm or less metallic impurities that contain a metal and its compounds.

Methods and systems for the super-resolution imaging can make visible strongly subwavelength feature sizes (even below 100 nm) in the optical images of biomedical or any nanoscale structures. The main application of the proposed methods and systems is related to label-free imaging where biological or other objects are not stained with fluorescent dye molecules or with fluorophores. This label-free microscopy is more challenging as compared to fluorescent microscopy because of the poor optical contrast of images of objects with subwavelength dimensions. However, these methods and systems are also applicable to fluorescent imaging. Their use is extremely simple, and it is based on application of the microspheres or microcylinders or, alternatively, elastomeric slabs with embedded microspheres or microcylinders to the objects which are deposited on the surfaces covered with thin metallic layers or metallic nanostructures. The mechanism of imaging involved use of the plasmonic near-fields for illuminating the objects and virtual imaging of these objects through microspheres or microcylinders. These methods and systems do not require use of fragile probe tips and slow point-by-point scanning techniques. These methods and systems can be used in conjunction with any types of microscopes including upright, inverted, fluorescence, confocal, phase-contrast, total internal reflection and others. Scanning the samples can be performed using micromanipulation with individual spheres or cylinders or using translation of the slabs. These methods and systems are applicable to dry, wet and totally liquid-immersed samples and structures.
