Apparatus and methods for providing and controlling a permanent magnet electro-mechanical device that functions as a motor or generator are disclosed. The electro-mechanical device uses control coils to steer magnetic flux of permanent magnets placed between stator segments. The control coils can be wound around the bridge of a stator segment, the poles of a stator segment or both. The electro-mechanical device can be single phase or multi-phase and can include controllers, sensors, a thermal/electrical insulating structure, or a reluctance gap. The stator poles are grouped and designed with an angular spacing that is based on the number of permanent magnets. The electro-mechanical device has a higher power density than conventional motors and generators and operates more efficiently, while operating at cooler temperatures.

The invention relates to the technical field of spatial filtering devices, and provides a spatial filtering device. The spatial filtering device comprises a frequency division lens, a recovery lens and at least two filtering small holes, wherein the frequency division lens and the recovery lens form a confocal optical system; and the filtering small holes are positioned between a focal point of the confocal optical system and the frequency division lens and/or the recovery lens. The plurality of the filtering small holes share scattering effect of high-frequency components of a laser beam evenly, the laser power absorption of one single filtering small hole is reduced so that the safety performance is improved, and the filtering effect of various kinds of high-frequency components of the laser beam is significantly improved so that the low-pass spatial filtering function can be better realized. Since the filtering small holes are positioned far away from the focal point, the size of faculae is large, the corresponding power density is low, and spark phenomenon is not liable to occur. In addition, the size of the filtering small holes is large, the processing difficulty is reduced, the misalignment tolerance of small hole adjustment is increased, and the system is easy to operate stably.

The invention discloses an application of a micelle as a photosensitizer formed by amphiphilic molecules and Ag2S quantum dots, and belongs to the technical field of nano materials. According to the application of a micelle as a photosensitizer formed by amphiphilic molecules and Ag2S quantum dots, the amphiphilic molecules are amphiphilic polymers or amphiphilic proteins, and include amphiphilicphospholipid molecules. Under the excitation of near-infrared light, the micelle changes from a ground state to an excited state, and reacts with surrounding oxygen molecules so as to enable the oxygen molecules to generate toxic photochemical products. The power density of the near-infrared light is 1-2.0 w/cm<2>. The micelle formed by the amphiphilic molecules and the Ag2S quantum dots in the invention has a photodynamic tumor cell-killing ability excited by the near-infrared light, has good blood compatibility, and solves the technical problems of phototoxicity and shallow treatment depth of photosensitizers in the prior art.

Disclosed is a method of manufacturing a solid oxide fuel cell including a multi-layered electrolyte layer using a calendering process. The method for manufacturing a solid oxide fuel cell is a continuous process, thus providing high productivity and maximizing facility investment and processing costs. In addition, the solid oxide fuel cell manufactured by the method includes an anode that is free of interfacial defects and has a uniform packing structure, thereby advantageously greatly improving the production yield and power density. In addition, the solid oxide fuel cell has excellent interfacial bonding strength between respective layers included therein, and includes a multi-layered electrolyte layer in which the secondary phase at the interface is suppressed and which has increased density, thereby advantageously providing excellent output characteristics and long-term stability even at an intermediate operating temperature.
