Abstract: Proposed is a catalyst complex having high activity for carbon dioxide conversion reaction that converts carbon dioxide to useful compounds through reaction of carbon dioxide and hydrocarbon containing at least one hydroxyl group, and a carbon dioxide conversion process using the same, wherein the catalyst complex includes, as an active metal in the catalyst complex, at least one of noble metals and at least one of transition metals other than noble metals, thereby having high activity for the carbon dioxide conversion reaction.

Abstract: Proposed is a high-yield simultaneous conversion method for a hydrogen source and a carbon dioxide source. The method significantly increases a yield of a formate through conversion of carbon dioxide. To this end, a carbon dioxide source and a hydrocarbon containing one or more hydroxy groups undergo a simultaneous conversion reaction in the presence of a solvent containing one or more alcohols and having a pH of 10 to 14.

Abstract: Proposed is a two-pot-two-step simultaneous conversion system for carbon dioxide and a hydrocarbon containing at least one hydroxy group and a method thereof. The system integrates a process of producing a metal salt that is a dehydrogenated form of the hydrocarbon, hydrogen, and water by reacting a hydrocarbon containing at least one hydroxy group in the presence of water and a metal oxalate, and a process of converting carbon dioxide or carbon dioxide-derived carbonate into formate by hydrogenation, thereby increasing energy efficiency while maintaining a higher hydrocarbon conversion rate and a higher carbon dioxide conversion rate than the one-pot conversion system for hydrocarbon and carbon dioxide.

Abstract: Methods for the oligomerization of ethylene, and more specifically, methods for the preparation of mainly ethylene oligomers of C10 or higher are described. A method can include performing a first oligomerization of an ethylene gas using a Ni-containing mesoporous catalyst, followed by a second oligomerization using an ion exchange resin, etc. to produce ethylene oligomers of C10 or higher. The method for the preparation of ethylene oligomers can produce C8-16 ethylene oligomers in high yield without inducing deactivation of the catalyst, compared to the conventional technology of ethylene oligomerization by a one-step process.

Abstract: A display driving device includes an encoding unit and a frame memory. The encoding unit is configured to generate final mode information and a compressed bit stream based on a macro block and a first reference pixel, and generate a final bit stream using the final mode information and the compressed bit stream. The frame memory is configured to store and provide the stored final bit stream to a decoding unit. The final mode information includes mode information and a reconstruction reference value. The mode information indicates a selected mode from a plurality of modes, each of the plurality of modes indicating selection pixels and non-selection pixels in the macro block. The selection pixels are pixels in the macro block selected for undergoing a compression operation, the non-selection pixels are pixels not selected for undergoing the compression operation, and the reconstruction reference value indicates encoding information for the non-selection pixels.
