Generalized lymphangiomatosis in patients treated for chylothorax following thoracoscopic sympathectomy: Case report.

Generalized lymphangiomatosis (GLA) is a very rare condition in adults, characterized by diffused proliferation of lymphatic vessels that requires differential diagnosis from other vascular disorders such as cavernous or capillary hemangioma. This is because of overlapping characteristics on histopathological examination. Therefore, imaging features such as CT and MRI are useful to evaluate morphological characteristics, location, and the extent of the spread as well as differential diagnosis with other pathologies.

Polyoxymethylene/silica/polylactic acid-grafted polyethylene glycol nanocomposites: structure, morphology, and mechanical properties and ozone and UV durability.

Polyoxymethylene (POM) is a semicrystalline thermoplastic that displays high tensile strength, thermal stability, and chemical durability. However, its widespread application is limited by its low elongation at break and thermal durability. In the present study, nanosilica (NS) and polylactic acid-grafted polyethylene glycol (PELA) were used as enhancement additives to improve the performance of POM homopolymer.

Hydrothermal Synthesis of Cobalt Doped Magnetite Nanoparticles for Corrosion Protection of Epoxy Coated Reinforced Steel.

Magnetite (Fe³O⁴) and Cobalt-doped Fe³O⁴ nanoparticles were obtained by hydrothermal reaction. The synthesized products were characterized by X-ray diffraction, Energy dispersive spectroscopy, Scanning electron microscopy, and Zeta potential. The results show that Co was substituted in the Fe³O⁴ crystal structure as CoFe₂O₄ phase.

Synthesis of Needle-Like BiVO₄ with Improved Photocatalytic Activity Under Visible Light Irradiation.

A highly crystallized monoclinic-scheelite type BiVO₄ powder was successfully synthesized using the solvothermal method. The as-synthesized BiVO₄ powder was characterized by XRD, FE-SEM, Raman spectroscopy, UV-Vis DRS spectroscopy, and TA-PL. Based on the XRD data and Raman spectra, the monoclinic-scheelite type BiVO₄ samples can be obtained at solvothermal synthesis temperatures higher than 140 °C.

Hg-Promoted Spirolactam Hydrolysis Reaction: A Design Strategy for the Highly Selective Sensing of Hg over other Metal Ions in Aqueous Media.

A mercury sensor (-(rhodamine-6G)lactam-ethylenediamine-4-dimethylamino-cinnamaldehyde-RLED) based on the Hg-promoted hydrolysis reaction has been designed and developed with a combination of theoretical calculations and experimental investigations. The interaction between RLED and Hg goes through a fast-initial stage with formation of a 1:1 complex, followed by a slow hydrolysis process. The formation of durable intermediate complexes is due to quite a long hydrolysis reaction time.

The Preparation and Characterization of Expanded Graphite via Microwave Irradiation and Conventional Heating for the Purification of Oil Contaminated Water.

Recently, the graphite based materials have gained interest as excellent platforms to remove aqueous pollutants via adsorption routes. This is given that such materials possess large specific surface area and low density. In the present work, a comparative study of two facile and effective approaches is conventional thermal heating and microwave irradiation methods to fabricate expanded graphite from available flake graphite sources of Vietnam for oil-contaminated water purification.

Magnetic NiFe₂O₄/Exfoliated Graphite as an Efficient Sorbent for Oils and Organic Pollutants.

This study aimed to fabricate, characterize and investigate the applicability of nickel ferrite (NiFe2O4 decorated exfoliated graphite for adsorptive removal of oils and organic compounds. The exfoliated graphite/NiFe2O4 was synthesized via a simple two-step process: (i) exfoliation of the lowcost natural graphite flakes using H2O2 as oxidizing agent and H2SO4 as intercalating agent, (ii) decoration of magnetic NiFe2O4 using the acid citric-based sol-gel process. The synthesized exfoliated graphite/NiFe2O4 hybrid was then applied for the sorption of diesel oil, vegetable oil, gasoline, petroleum ether and tetrahydrofuran.

Synthesis of Metal Ion-Doped TiO2 Nanoparticles Using Two-Phase Method and Their Photocatalytic Activity Under Visible Light Irradiation.

In this study, TiO2 and metal ion-doped TiO2 nanoparticles were successfully synthesized by solvothermal reaction of titanium butoxide precursor in the presence of oleic acid, oleylamine and vapor water and they were characterized by XRD, Raman, TEM and DRS. We also investigated the photocatalytic activity of these oxides for the decomposition of Rhodamine B. From XRD and Raman results, doping of the metal ion in the crystal lattice did not change the high crystallinity of the TiO2 structure, and all the metal ions were incorporated into the structures of titania as well as replaced titanium ion or located at interstitial site.

Photocatalytic Decomposition of Methylene Blue Over MIL-53(Fe) Prepared Using Microwave-Assisted Process Under Visible Light Irradiation.

Iron-based MIL-53 crystals with uniform size were successfully synthesized using a microwave-assisted solvothermal method and characterized by XRD, FE-SEM and DRS. We also investigated the photocatalytic activity of MIL-53(Fe) for the decomposition of methylene blue using H2O2 as an electron acceptor. From XRD and SEM results, the fully crystallized MIL-53(Fe) materials were obtained regardless of preparation method.
