Abstract: The spin-orbit torque-based random number generator includes a spin torque generation layer including a first spin torque layer and a second spin torque layer, a magnetization-free layer, a tunnel barrier layer, and a magnetization pinned layer, wherein the second spin torque layer is disposed between the magnetization-free layer and the first spin torque layer and generates field-like torque (FLT) and damping-like torque (DLT) related to the magnetization direction of the magnetization-free layer; the first spin torque layer adjusts a torque ratio according to the size of field-like torque to the size of damping-like torque in conjunction with the thickness of the second spin torque layer; in the magnetization-free layer, a magnetization direction is randomly aligned up or down based on the adjusted torque ratio; and a random number is generated based on current that is switched and output based on the randomly aligned magnetization direction.

Abstract: Disclosed is a molecular diode using the assignment of electrical properties to inactive organic molecules when a self-assembled monolayer (SAM) thin film including an electrically inactive organic molecule is formed without synthesizing a separate organic molecule having electrical activity. The disadvantage of the instability of a conventional SAM can be overcome, a function can be extended, and electrical properties, such as a rectification characteristic in a non-functional molecule, can be induced even without the design and synthesis of organic molecules for introducing a functional molecule. Accordingly, the embodiments of the present disclosure can be usefully used in various technical fields in which an SAM is used, in particular, wide fields such as electronics, an organic display (OLED), solar cells, sensors, non-uniform catalysts, frictional electricity, cell growth surfaces, and a heat transfer control film.

Abstract: The present invention relates to a radiative cooling paint consisting of ceramic fine particles as pigments, a polymer resin as a binder, and a solvent. According to the present invention, a substrate is coated with the radiative cooling paint, and then a paint film layer is formed. The paint film layer performs a radiative cooling function by preventing energy inflow from incident sunlight by maximizing reflection of incident sunlight; minimizing absorption of incident sunlight; and maximizing emission of long-wavelength infrared light corresponding to 8 μm to 13 μm and increasing energy discharge through emission of long-wavelength infrared light, and pores with a volume of 3% to 50% are formed inside the paint film layer to enhance reflection of incident sunlight without reducing emission of long-wavelength infrared light.

Abstract: The present disclosure relates to a resonant regulating rectifier, including an input unit that receives wireless power; and a resonant regulating rectification unit that modulates and rectifies a voltage level of the wireless power based on PWM according to a first demand voltage of a first load and a second demand voltage of a second load to apply a first target voltage to the first load through a first output transistor, and apply a second target voltage to the second load through a second output transistor. This may allow another output to be generated by utilizing a section wasted in a PWM method that modulates a voltage width, thereby reducing wasted energy.
