Micromotors Go In Vivo: From Test Tubes to Live Animals

18-Dec-2017 | Berta Esteban‐Fernández de Ávila, Pavimol Angsantikul, Jinxing Li, Wei Gao, Liangfang Zhang, Joseph Wang, Advanced Functional Materials, 2017

Abstract While synthetic micromotors have been evaluated extensively under in vitro conditions for over a decade, their in vivo function has rarely been explored. Recent research effort has resulted in micromotors that display fast movement in complex biological media, and possess efficient ...

Inhibition of Tetrahydrofuran Hydrate Formation in the Presence of Polyol-Modified Glass Surfaces

25-Jul-2017 | Jeffrey R. Hall; Paul W. Baures, Energy & Fuels, 2017

Glycerol was conjugated to glass test tube surfaces in four configurations by employing two different silane spacers, covalent attachment to glycerol at either the 1- or the 2-position, and with a succinic acid spacer. The resulting surfaces were tested for their ability to inhibit the nucleation ...

Upscaled Bioammonium/Ammonia Production by Clostridium Aminophilum Cultured with Soy Protein Isolate

29-Mar-2017 | Brian K. Ward; Robert J. Dufault; Richard Hassell; Matthew A. Cutulle, Journal of Agricultural and Food Chemistry, 2017

The goal of this study was to scale up the production of bioammonium/ammonia (BAA) by Clostridium aminophilum from test tube size small batches of 1.0 g of soy protein isolate (SPI) with 10 mL of salt solution to the lab scale bioreactor level of 1.8 kg·18 L–1 salt solution in amounts required ...

A short history of phototherapy, vitamin D and skin disease

06-Dec-2016 | Paul Jarrett; Robert Scragg, Photochemical & Photobiological Sciences, 2016

The earliest record between sun exposure and skin disease goes back five millennia to the ancient Egyptians. The modern scientific era of medical light therapy and skin diseases started in 1877 when Downs and Blunt reported that exposure to light inhibited fungal growth in test tubes. Continuing ...

How the different material and shape of the blood collection tube influences the Concentrated Growth Factors production

18-Sep-2016 | Veronica Bonazza, Elisa Borsani, Barbara Buffoli, Stefania Castrezzati, Rita Rezzani, Luigi Fabrizio Rodella, Microscopy Research and Technique, 2016

Abstract Platelet concentrates, such as Concentrated Growth Factors (CGF), are autologous preparations obtained from the patient's own blood and rich in platelets, growth factors and cytokines involved in the key processes of tissue regeneration. These autologous concentrates differ in the way ...

Contamination risk of stable isotope samples during milling

08-Jun-2016 | M. Isaac‐Renton, L. Schneider, K. Treydte, Rapid Communications in Mass Spectrometry, 2016

Rationale Isotope analysis of wood is an important tool in dendrochronology and ecophysiology. Prior to mass spectrometry analysis, wood must be homogenized, and a convenient method involves a ball mill capable of milling samples directly in sample tubes. However, sample‐tube plastic can ...

Non‐Isothermal Kinetic Models of Degradation of S‐Methylmethionine

14-Jul-2015 | Yarong Huang, Johannes Tippmann, Thomas Becker, Journal of Food Process Engineering, 2015

Abstract Dimethyl sulfide (DMS), which has a characteristic taste and aroma of cooked celery, is one of the most studied off‐flavors in wort and beer. Although there have been many kinetic studies conducted with different wort boiling systems under isothermal conditions, the results are ...

Fusion of Microlitre Water-in-Oil Droplets for Simple, Fast and Green Chemical Assays

21-May-2015 | Shih-Hao Chiu; Pawel Lukasz Urban, Analyst, 2015

A simple format for microscale chemical assays is proposed. It does not require the use of test tubes, microchips or microtiter plates. Microlitre-range (ca. 0.7 – 5.0 μL) aqueous droplets are generated by commercial micropipette in a non-polar matrix inside a Petri dish. When two droplets are ...
