We describe the design, synthesis and fluorescent profile of a family of environment-sensitive dyes in which a dimethylamino (donor) group is conjugated to a cyanoacrylate (acceptor) unit via a cyclopenta[b]naphthalene ring system. This assembly satisfies the typical D-π-A motif of a fluorescent molecular rotor and exhibits solvatochromic and viscosity-sensitive fluorescence emission. The centr...

A robust nanogenerator based on poly(tert-butyl acrylate) (PtBA)-grafted polyvinylidene difluoride (PVDF) copolymers via dielectric constant control through an atom-transfer radical polymerization technique, which can markedly increase the output power, is demonstrated. The copolymer is mainly composed of α phases with enhanced dipole moments due to the π-bonding and polar characteristics of th...

A 13-year-old boy presented with an arteriovenous malformation (AVM) involving the left mandible that bled after intraoral biopsy. The AVM was treated on an emergency basis by primary intravenous delivery of n-butyl cyanoacrylate after transfemoral catheterization, resulting in complete anatomic and clinical cure.

OBJECTIVE To study the preparation of seeding type immobilized microorganisms and their degradation characteristics on di-n-butyl phthalate (DBP). METHODS Diatomite, clinoptilolite, silk zeolite, and coal fly ash were chosen as reserved materials and modified. Their adsorption capacity and intensity in the bacteria were determined and the best carrier was picked out. The seeding type immobili...

Injection of N-butyl-2-cyanoacrylate has been used successfully for treatment of gastric variceal bleeding. Bacteremia after injection of N-butyl-2-cyanoacrylate is well known, however, the method for diagnosis of infected endovascular injected material has remained uncertain. This is the first case reporting use of F-18 FDG PET/CT in detection of the source of infection after control of endosc...

Glue embolisation is a rare happening and many clinicians who evaluate patients for post sclerotherapy problems may be unaware of this complication. We present a case of pulmonary embolism in a patient of cirrhosis liver secondary to gastric variceal sclerotherapy with N-Butyl-2-cyanoacrylate and lipoidol solution. This is also called glue embolism.

We experienced a case with a gastric varix that did not have a catheterizable main drainage vein and had multiple afferent veins. For this case we successfully performed percutaneous transhepatic sclerotherapy using the following procedure. After the drainage vein was embolized by metallic coils and n-butyl cyanoacrylate from a microcatheter that was advanced through the gastric varix, 5% ethan...

The NO chemisorption dynamics on ordered multilayer iron phthalocyanine (FePc) and quasiamorphous multilayer tetra-t-butyl FePc (ttbu-FePc) films on a Au(111) substrate was investigated using the King and Wells reflection technique. The NO zero coverage or initial sticking probabilities (S(0)) were measured as a function of sample temperature (T(s)) and beam energy (E(i)). The experimental resu...

In this study, we evaluated reactivity of organic peroxides with metals. The effect of useful metals for decomposition of organic peroxides was measured by Differential Scanning Calorimeter (DSC). Results of DSC measurement with several kinds of sample cells showed that some of organic peroxides have high reactivity with gold plated cell. Hydroperoxides were decomposed lower temperature by usin...
