Abstract: A method and device for grasping tissue using the tissue forceps with wide jaws. The tissue forceps include a first arm and a second arm joined at a vertex at a proximal end. The first arm and the second arm have distal portions which are extensions angled leftward away from the longitudinal axis of the first and second arms. Wide forceps jaws terminate the distal end of the angled extensions and the terminal inner surfaces of the jaws have serrated edges. The forceps is adapted to sequentially grasp tissue on opposed sides of a tissue interface and then present the tissue for further procedure. The jaws can be straight, convex, or concave to hold, stabilize and manipulate tissue flap borders with better grasping and control. The jaws can be in line with the handle (straight) or 45 or 90 degrees offset for better access to different surgical site's locations.

Abstract: Modified chemical structures of cardanol extracted from cashew nut shell oil, and the use of the same to prepare imidazolium ionic liquids (IILs). The IILs can be used to prepare different types of silica, magnetite and calcium carbonate nanoparticles (NPs) as multifunctional oilfield chemicals for use in various oil spill collection, de-emulsification, viscosity improvement, asphaltene dispersant, and enhanced oil recovery applications.

Abstract: The dual bone forceps may be considered tandem locking forceps wherein the forceps are coupled to each other so that the surgeon may use one for clamping the bone graft plate adjacent the graft site while clamping the other forceps to a supporting bone structure above, below, or lateral to the graft site during the procedure. The dual bone forceps includes a bone graft plate clamping forceps having clamping jaws at the anterior end and flat handles terminating in locking jaws at the posterior end. The dual bone forceps also includes an anchoring forceps having an elongate hook blade and a shortened anvil blade at the anterior end and locking handles at the posterior end. A linking bar extends non-coplanar from the shortened anvil blade to the pivot of the bone graft plate clamping forceps to maintain the two forceps linked to each other, but spaced apart in different planes.

Abstract: A DC compensation device having an integrated energy storage which allows it to store excess energy from a renewable energy source or supply its stored energy when the renewable energy source is not able to provide the expected energy. The device has three modes of operation. Normal operation delivers full current from the renewable energy source to the load. Series and parallel operations serve to improve the power quality of the grid.

Abstract: The chromatographic column is a stainless steel column having a stationary phase of porous monolithic polymer chemically bonded to the interior wall of the stainless steel column so that the stationary phase is fixed and immobile and does not require frits or other seals to retain particulate matter or a slurry in the column. The inner wall of the column is oxidized and then vinylized with a difunctional linker to chemically bond the polymer to the column. The difunctional linker may be 3-(trimethoxysilyl) propyl methacrylate, vinyl trimethoxysilane, 3-mercaptopropyl trimethoxysilane, or glycidoxypropyltrimethoxysilane. The monolithic polymer is prepared in situ in the column by radical polymerization of a monovinyl monomer with a crosslinking divinyl monomer. The column may be a conventional stainless steel column (¼″ inner diameter), capillary micro-LC ( 1/16″), or nan-LC (( 1/32″).

Abstract: A dental clamp retractor includes tongue and cheek retractor portions separated by a clamp bow having an arcuate shape. A buccal extension arm extends laterally outward from the clamp bow to the cheek retractor portion. A buccal gauze holder is connected to the clamp bow by a flexible arm. The tongue retractor portion connects to the clamp bow by a lingual extension arm. A lingual gauze holder is connected to the clamp bow by a flexible arm. The cheek retractor portion may have a larger surface area than the tongue retractor portion and be formed of an elastomer. The buccal gauze holder and lingual gauze holder may be formed by clips. A dental procedure includes applying the dental clamp retractor to a patient to retract the tongue and cheek and hold gauze on a buccal and/or labial side of a tooth surface of the patient.

Abstract: A method of forming a stationary phase of a capillary column for gas chromatography includes in situ growth of a metal-organic framework on an inner surface of the capillary column. The capillary column may include fused silica on an inner surface thereof and can be treated to provide functional groups capable of forming covalent bonds with a difunctional organic linker of the metal-organic framework. Epitaxial growth of the metal organic framework can occur directly on the inner surface of the capillary tube to a desired uniform thickness, controllable by concentration of metal organic framework precursors.

Abstract: An endodontic file measuring device includes a housing with an upper opening for receiving the file within a file channel in the housing. A movable base is disposed in the file channel and a plurality of sensors are disposed along the file channel. When a tip of the endodontic file is positioned on the movable base, the sensors can detect a presence of the file within the channel and measure a length of the file in the channel. A slider protrudes from the front wall of the housing and is connected to the base by a connecting rod. The slider can be manipulated by the user to lower or elevate the file within the base. A display on an outer surface of the housing displays the length of the file present in the file channel.
