A sealant for sealing a puncture through tissue includes a first section, e.g., formed from freeze-dried hydrogel, and a second section extending from the distal end. The second section may be formed from PEG-precursors including PEG-ester and PEG-amine, e.g., in an equivalent ratio of active group sites of PEG-ester/PEG-amine greater than one-to-one, e.g., such that excess esters may provide faster activation upon contact with physiological fluids and enhance adhesion of the sealant within a puncture. At least some of the precursors remain in an unreactive state until exposed to an aqueous physiological environment, e.g., within a puncture, whereupon the precursors undergo in-situ cross-linking to provide adhesion to tissue adjacent the puncture. For example, the PEG-amine precursors may include the free amine form and the salt form. The free amine form at least partially cross-links with the PEG-ester and the salt form remains in the unreactive state in the sealant before introduction into the puncture.

An electrode assembly comprises an electrode support, an electrode on the electrode support, the electrode having a working surface extending generally transverse to a thickness of the electrode, and a filament of electrically insulative material overlying a portion of the working surface of the electrode and at least partially extending through the thickness of the electrode. An electrosurgical may include an end effector having a jaw member comprising such an electrode assembly.

An insulating container can be configured to retain a volume of liquid, and include a first inner wall having a first end having an opening extending into an internal reservoir, and a second outer wall forming an outer shell. The second outer wall can include a second end configured to support the container on a surface. The second outer wall can include a dimple, and the dimple can include a circular base and an inner portion converging to an opening extending into the second outer wall. The opening can be sealed by a resin, and the circular base can be covered by disc formed of the material. The outer wall and the inner wall can be constructed from different materials such that the outer wall is harder and resists indentation, and the inner wall reduces the overall weight of the container.

The present disclosure provides a lightweight spar cap with a concave structure for a wind turbine blade and a manufacturing method thereof, a wind turbine blade and a manufacturing method thereof. The lightweight spar cap is groove-shaped as a whole, and includes supporting portions located on two wings of the lightweight spar cap and an intermediate connecting portion connecting the two supporting portions. The manufacturing method of the lightweight spar cap includes laying a reinforcing body of the intermediate connecting portion and a supporting material of the supporting portion, and performing resin infusion. By comprehensively considering multiple factors, the present disclosure reduces the weight of the wind turbine blade, improves the material utilization of the wind turbine blade, and realizes a lightweight wind turbine blade.

A joint structure includes a first member having a fit-in groove, a second member made of a material different from a material of the first member and having an insertion section to be inserted into the fit-in groove, and a plurality of bonding layers having different hardness and formed between the fit-in groove and the insertion section.
