Nanoengineered barrier invented to protect plastic electronics from water degradation

... onto plastic substrates. These defects cause a pore effect, where oxygen and water molecules are able ... has taken an innovative approach to resolve the pore effect by literally plugging the defects in the ... three only. IMRE has successfully resolved the pore effect issue in multi-layered barrier stacks and ...

Canadian research team reports major breakthrough in lithium battery technology

... carbon. At the nanoscale level, this type of carbon has a very uniform pore diameter and pore volume. Using a nanocasting method, the team assembled a structure of ...

Sophisticated soil analysis for improved land use

... each of the elements themselves there is variation, such as different pore shapes and different elemental solids. Many approaches have been used ... these different multi-scale methods to diverse data sets including soil pore shapes, soil aggregates, water content, rate of water movement, gas ...

International Products Corp.'s Lab Offers Filter Membrane Compatibility and Studies

... number of test scenarios possible. According to Research Scientist, Al Gabbianelli, "We have a variety of membrane substrates with different pore sizes to test. Plus, by adjusting variables like permeate pressure, hydraulic pressure, circulation time, concentration, and shim gap an optimum ...

DNA gripped in nanopores

... The measurements revealed that the retarding forces exerted by the ions, slowly decreased if the DNA moved through a larger nanopore. The bigger the pore the smaller the resistance. Calculations based solely on electrostatic forces had yielded other expectations. The hydrodynamic environment was found ...

Metals shape up with a little help from friends

... larger diameter than previous attempts have been able to produce. Platinum is, so far, the best available catalyst for fuel cells, and a spacious pore structure allows fuel to flow through and react over a larger surface area. "It opens a completely novel playground because no one has been able ...

LLNL researchers peer into water in carbon nanotubes

... filters. Earlier Livermore studies have suggested that carbon nanotubes may be used for desalination and demineralization because of their small pore size and enhanced flow properties. Conventional desalination membranes are typically much less permeable and require large pressures, entailing high ...

Rayovacs IT team discusses network security, Sarbanes-Oxley and ROI myths

... be impacted and which need to improve? Problem was, at the time, we didnt know the scope of our own vulnerabilities and our CFO didnt have time to pore over binders full of reports. Brent Leland : To solve this problem, we identified an automated vulnerability assessment vendor, Beyond-IP , and ...

Elimination of phone tax tempered by paperwork

... Service nor telephone companies will be required to calculate the taxes paid by business consumers. Companies or their tax preparers will have to pore through phone bills dating back to March 1, 2003, to figure out their refund. That distresses Brian Erlichman, senior vice president of Business ...

Testing Compressed Air Lines for Microbiological Contamination

... thereby resulting in migration and potential strike-through. Also, there may be a contaminant in the environment which is smaller than the pore size of the pre-filter. Again, this may lead to the inefficiency of the pre-filter. Microorganisms A ...

Separation of Peptides by Hydrophilic Interaction Chromatography Using TSKgel Amide-80

... averaged 92% as shown in Table 1 . Recovery with the Amide-80 column was higher when compared to a column packed with an 80 pore size, end capped ODS material(3). Reproducibility and repeatability were determined by examining both the ...

Fully Automated Nano-Electrospray Coupled with a Finnigan LCQ Deca XP Plus for Sub-fmol Proteomic Analysis

... peptides were eluted from the trap and separated on a reversed-phase capillary column (PicoFrit TM ; 5 μm BioBasic C18 [Thermo Electron], 300 pore size; 75 μm 10 cm; tip 15 μm, New Objective, Woburn, MA, USA) with a 30-min linear gradient of 060% acetonitrile in 0.1% formic acid/water ...

The combination of monolithic columns and modern HPLC/MS/MS instrumentation for high chromatographic throughput and sensitive detection of beta-agonists

... run, longer chromatographic separation times have to be accepted. Monolithic columns are made of a single piece of porous silica with a defined pore structure. Thus, lower back pressure in the column allows the use of higher flow rates and flow gradients, without loss in chromatographic ....

Delivering siRNAs to Difficult Cell Types

... gene expression, while retaining high cell viability. Ambion's siPORT siRNA Electroporation Buffer works by facilitating rapid pore resealing. Using the siPORT siRNA Electroporation Buffer with square wave-type pulses, we were able to transfect hMSC cells, ...
