Abstract: Visible and infrared radiation photothermoelectric effect photodetectors are provided. The photodetectors are formed on substrates having a low thermal diffusivity of less than 0.05 mm2/sec. A thermoelectric metal chalcogenide film is formed on the low thermal diffusivity substrate. At least two symmetric electrodes are formed on the thermoelectric metal chalcogenide film such that the thermoelectric metal chalcogenide film forms a channel between the electrodes. The photodetector has a responsivity of at least approximately 65 V W?1 for 1550 nm illumination and a response time less than approximately ˜60 ms. The photodetector photoresponse is tunable via manipulation of local illumination. Examples of photodetectors use Bi2Se3, Bi2Te3, and SnSe2 on flexible polymeric substrates. By using large-area thermoelectric films with a photothermal detection mechanism, and modulating responsivity via thermal coupling, photodetector arrays for wearable electronics and integrated optoelectronic circuits may be created.

Abstract: Disclosed is an incomplete dimensionality augmentation-based optimization method for a data-driven power system. By dividing a power flow independent variable into a control variable and a disturbance variable, such as power of a controllable power supply and an uncontrolled voltage amplitude, only the disturbance variable is subjected to dimensionality augmentation, to adapt to the nonlinear characteristic of the power flow; and the control variable keeps a power flow constraint as a linearized expression of the control variable, thereby simplifying a power flow constraint form and solution, and achieving a higher-accuracy of optimization. The power optimization scheduling of distributed photovoltaic can be implemented by the optimization method provided in the present invention.

Abstract: Electrocatalytic overall water splitting to generate hydrogen and oxygen is a green and sustainable approach with zero carbon emission, which is important for the future renewable energy landscape. The practical application of this approach is challenging due to the sluggish reaction kinetics of water activation at high current densities, which are hard to overcome. Although high-performance alkaline bifunctional electrocatalysts may be useful, current catalysts lack both activity and durability. One approach is to rationally design bifunctional two-dimensional (2D) heterostructures but obtaining an efficient and durable catalyst has proved difficult. The present disclosure relates generally to an electrocatalyst including a 2D heterostructure (Ru-CMOP), methods of making and using the same. The catalyst of the present disclosure is designed for high activity and good durability at industrial-level high current densities.

Abstract: Approaches are presented for training an inverse graphics network. An image synthesis network can generate training data for an inverse graphics network. In turn, the inverse graphics network can teach the synthesis network about the physical three-dimensional (3D) controls. Such an approach can provide for accurate 3D reconstruction of objects from 2D images using the trained inverse graphics network, while requiring little annotation of the provided training data. Such an approach can extract and disentangle 3D knowledge learned by generative models by utilizing differentiable renderers, enabling a disentangled generative model to function as a controllable 3D “neural renderer,” complementing traditional graphics renderers.
