We investigate TMMF photopolymer as a cost-efficient alternative to glass for the leak-tight sealing of high-density silicon microchannels. TMMF enables low temperature sealing and access to structures underneath via lamination and standard UV-lithography instead of costly glass machining and anodic bonding. TMMF is highly transparent and has a low autofluorescence for wavelengths larger than 4...

When sealing liquids with magnetic fluid, the interfacial stability problem caused by interaction between fluid and sealed liquid leads to poor performance. Centrifugal force is generated rotation of in back blade seal, which forms pressure reduce load seal or prevents from leaking. To influence shaft speed on performance, a combined was designed for experiment stand set up. Theoretical experim...

The aim of this study was to analyze the laboratorial performance of dentin-bonding agents, glass ionomer cements and compomers, regarding the sealing of the gingival margins of class V cavities, prepared on the cementoenamel junction. Standardized class V cavities (4 x 3 x 2 mm) were prepared on the buccal and lingual/palatal surfaces of 20 extracted human third molars. Forty cavities were res...

The study was done to assess the sealing ability and adaptation of RealSeal 1, and to compare it with Thermafil. 65 single-rooted extracted teeth were selected and root canal treatment was performed. Root canals were obturated with RealSeal 1 or Thermafil. A double chamber bacterial leakage model using E. faecalis was developed to assess the sealing ability. Samples were monitored daily for 60 ...

This communication demonstrates the relevance of membrane sealing in a test cell to its performance. Membranes need to be sealed, and therefore a more or less signifcant (depending on the test cell design) peripheral part of the membrane is supported directly by the cell body (instead of a permeate spacer). Although it may seem that there should be no fltration through ...

Introduction. This study compared streamlined liner of the pharynx airway (SLIPA) and I-gel noninflatable, single-use, supraglottic airway device (SAD) performance in anesthetized, paralyzed adults. Methods. Eighty adults (ASA physical statuses I-III) who were undergoing elective procedures under general anesthesia with an SAD were enrolled in this prospective, randomized, single-blind study. S...

Surgical sealants have been used for sealing or reconnecting ruptured tissues but often have low adhesion, inappropriate mechanical strength, cytotoxicity concerns, and poor performance in biological environments. To address these challenges, we engineered a biocompatible and highly elastic hydrogel sealant with tunable adhesion properties by photocrosslinking the recombinant human protein trop...
