The distal tip of the ultrasonic blade is configured to direct electrosurgical energy.

Abstract: An end effector assembly of a surgical instrument includes an ultrasonic blade. A jaw member is movable relative to the ultrasonic blade from a spaced-apart position to an approximated position. The jaw member includes a structural body. The structural body defines a first side facing the ultrasonic blade and a second side facing away from the ultrasonic blade. A jaw liner is engaged with the first side of the structural body such that the jaw liner contacts the ultrasonic blade when the jaw member is in the approximated position. An electrode is engaged with the second side of the structural body. The electrode is adapted to connect to a source of electrosurgical energy. The electrode defines a first portion and a second portion. The first portion of the electrode is in contact with the structural body and the second portion of the electrode tapers to a pointed edge.

Abstract: A computer system displays a first object that includes at least a first portion of the first object and a second portion of the first object and detects a first gaze input that meets first criteria, wherein the first criteria require that the first gaze input is directed to the first portion of the first object in order for the first criteria to be met. In response, the computer system displays a first control element that corresponds to a first operation associated with the first object, wherein the first control element was not displayed prior to detecting that the first gaze input met the first criteria, and detects a first user input directed to the first control element. In response to detecting the first user input directed to the first control element, the computer system performs the first operation with respect to the first object.

Abstract: A surgical end effector includes an ultrasonic blade and a jaw member. The blade is adapted to receive ultrasonic and electrosurgical energy and defines a distal face. The jaw member is movable relative to the blade from a spaced-apart to an approximated position for clamping tissue and includes a structural body having a body portion and a distal cap portion. The distal cap portion defines an electrode that receives electrosurgical energy. The jaw member further includes a jaw liner engaged within the body portion and extending therefrom towards the blade such that, in the approximated position, the jaw liner contacts the blade to define a gap distance between the electrode and the distal face to facilitate bipolar electrosurgical tissue treatment upon conduction of bipolar energy between the electrode and the distal face and through tissue in contact therewith.

Abstract: The invention comprises a method for the oxidation of alkanes to alcohols and for decomposition of hydroperoxides to alcohols utilizing new compositions of matter, which are metal complexes of porphyrins. Preferred complexes have hydrogen, haloalkyl or haloaryl groups in meso positions, two of the opposed meso atoms or groups being hydrogen or haloaryl, and two of the opposed meso atoms or groups being hydrogen or haloalkyl, but not all four of the meso atoms or groups being hydrogen. Other preferred complexes are ones in which all four of the meso positions are substituted with haloalkyl groups and the beta positions are substituted with halogen atoms. A new method of synthesizing porphyrinogens is also disclosed.

Abstract: Alkanes are catalytically oxidized in air or oxygen using iron-substituted polyoxoanions (POAs) of the formula:H.sub.e-z ?(n-C.sub.4 H.sub.9).sub.4 N!.sub.z (XM.sub.11 M'O.sub.39).sup.-eThe M' (e.g., iron(III)/iron(II)) reduction potential of the POAs is affected by selection of the central atom X and the framework metal M, and by the number of tetrabutyl-ammonium groups. Decreased Fe(III)/Fe(II) reduction potential has been found to correlate to increased oxidation activity.
