  • Patent number: 12232649
    Abstract: The present application pertains to an electric arc grill that integrates a range of components for enhanced functionality. Central to this grill is the electric heating device, which includes an electric heating component and a circuit board integrated with electric components. The electric heating component includes an electric output head and an electric connection rod that is securely attached to and electrically connected with the head, ensuring a stable connection to the circuit board. The grill is equipped with a lifting device that is affixed to and grounded by the grill carrier, facilitating the electrical connection with the fire gathering plate. This plate is positioned above the electric output head, creating a gap that is instrumental in generating the electric arc necessary for heating. The grill enables the fire gathering plate to be heated via electric arc, thereby providing a versatile cooking surface capable of frying, grilling, and baking.

  • Publication number: 20230046065
    Abstract: Palladium-catalyzed C(sp3)—H arylation of aliphatic carboxylic acids, amides and ketones with BNA-encoded aryl iodides in water is disclosed, Furthermore, sequential C—H arylation chemistry enabled the on-DNA synthesis of structurally-diverse scaffolds containing enriched C(sp3) character, chiral centers, cyclopropane, cyclobutane, and heterocycles. That new chemistry permits preparation of a DNA—encoded library (BEL) technology that can dramatically expedite hit identification in drug discovery owing to its ability to perform protein affinity selection with millions or billions of molecules in a single experiment. The sequential functionalization of multiple C—H bonds provides an unique avenue for creating diversity and complexity from simple starting materials. The use of water as solvent, the presence of DMA, and the extremely low concentration of DMA-encoded coupling partners (0.

  • Publication number: 20220195176
    Abstract: The present invention provides a polyformaldehyde composite material, in parts by weight, including the following components: 70 to 95 parts of a polyformaldehyde; 5 to 20 parts of a SEBS; wherein, the SEBS is acid modified or amine modified. Due to modification by acid or amine, and presence of a polystyrene segment, a compatibility of the SEBS with the polyformaldehyde reduces because of a steric hindrance effect, which reduces an ability of a POM molecular chain to arrange regularly. When injection molded into a product or template, an incompatibility of the material itself will form a micro-rough effect on a surface of the material. When an incident light reaches the micro-rough surface, a reflection direction of the light will change and thus a diffuse reflection occurs, and a low-gloss material is obtained.

  • Patent number: 11249590
    Abstract: This application is directed to intra-panel communication in a touch display device in which a touch-integrated timing controller (TTCON) is coupled to touch-embedded source drivers (TSDs) via a plurality of forward links and a set of backward links. The forward links include a first subset of display forward links and a second subset of touch forward links. The TSDs are electrically coupled to a display panel including a plurality of display pixels and a plurality of touch sensors. The TTCON sends a display drive signal including display content data and display control data over the display forward links, and sends a touch control signal including an instruction to initiate an operation mode over the touch forward links. Upon receiving the touch control signal, the TSDs identify the instruction to initiate the operation mode, generate touch data accordingly, and return the touch data to the TTCON via the backward links.

  • Patent number: 11186563
    Abstract: Chiral acetyl-protected aminoethyl quinoline (APAQ), pyridine and imazoline ligands are disclosed that enable Pd (II)-catalyzed enantioselective arylation or heteroarylation of ubiquitous prochiral ?-methylene C—H bonds of aliphatic amides offers an alternative disconnection for constructing ?-chiral centers. Systematic tuning of the ligand structure reveals that a six-membered instead of a five-membered chelation of these types of ligands with the Pd(II) is important for accelerating the C(sp3)-H activation thereby achieving enantioselectivity for quinoline and pyridine ligands.
