    • Evaluations of a New Ionic Liquid Stationary Phase with PEG Like Selectivity Evaluations of a New Ionic Liquid Stationary Phase with PEG Like Selectivity Leonard M. Sidisky, Supelco R&D Manager Recorded: Oct 31 2012 3:00 pm UTC 49 mins
    • Geminal dicationic and polyionic ionic liquids have been prepared for use as stationary phases in capillary gas chromatography. These materials are known to provide higher thermal stability for gas chromatography, broader liquid working ranges and broader selectivity ranges than monocationic ionic liquids and polymeric based stationary phases with similar polarity. Recently, a new ionic liquid stationary phase has been developed that provides a selectivity very similar to a polyethylene glycol (PEG) selectivity but with increased thermal stability and lower bleed. We will compare and contrast the similar but unique selectivity of this new phase with traditional PEG phases using a wide variety of different sample types. We will demonstrate the improved thermal stability and lower bleed through a series of different studies and applications.

    • Ionic liquid GC columns for the quantitation of trans fatty acids in fats & oils Ionic liquid GC columns for the quantitation of trans fatty acids in fats & oils Pierluigi Delmonte, Ph.D - U.S. Food and Drug Administration Recorded: May 16 2012 3:00 pm UTC 39 mins
    • The fatty acid composition of a fat or oil is most commonly assessed by gas chromatography, following conversion of the fatty acids methyl esters. The current most refined analytical methods for the quantitation of trans fatty acids rely on the separations provided by long cyanopropyl siloxane capillary columns. The introduction of capillary columns coated with ionic liquids, such as Supelco SLB-IL111, provide an alternative separation tool characterized by a higher stationary phase polarity and selectivity toward geometric and positional isomers of unsaturated fatty acids. The use of these novel capillary columns can provide more refined separations of complex lipid samples. As a result, most conjugated linoleic acid isomers (including t7,c9- and c9,t11-18:1 FA) can be quantitated in a single separation using a 100 m SLB-IL111 capillary column and most 18:1 FA positional and geometric isomers can be separated using a 200 m SLB-IL111. Ionic liquid columns provide more detailed FA profiles, especially for unsaturated fatty acid positional/geometric isomers.

    • Liquid-Cooled IT for the Masses:  Achieving a Data Center PUE of 1.1 Liquid-Cooled IT for the Masses: Achieving a Data Center PUE of 1.1 Tahir Cader, HP Servers Distinguished Technologist Recorded: Jan 22 2015 6:00 pm UTC 59 mins
    • Data center energy efficiency is being attacked from numerous directions, including power distribution innovations, the creation of hardware better suited to customer applications (to drive better IT utilization), co-designing data centers with IT solutions, and cooling system innovations.

      With respect to cooling systems, the widely-recognized Power Usage Effectiveness (PUE) from The Green Grid (TGG), which is a direct measure of data center energy efficiency, has been used to great effect to continuously drive down “traditional” air-cooled data center PUEs. In the high performance computing (HPC) space, where 40 kW+ rack power densities are commonplace, more aggressive cooling technologies such as liquid-cooling, are seeing rapid adoption. There is also increasing evidence that liquid-cooling is making its way into non-HPC data centers. The presentation will cover such topics as:

      · Data center energy efficiency trends
      · An overview of liquid-cooling technologies
      · The role that liquid-cooled IT is playing in driving improved energy efficiency – towards a PUE of 1.1
      · The challenges of implementing liquid-cooling in the IT and data centers

      The goal is to help demystify liquid-cooling. Finally, The Green Grid’s recently announced Liquid-Cooling Work Group will be described.

    • The New Dynamic: Exempt securities in the US & resales of restricted securities The New Dynamic: Exempt securities in the US & resales of restricted securities Anna Pinedo and David Lynn, Morrison & Foerster; Annemarie Tierney, NASDAQ; Tom Young, IFLR Recorded: Feb 24 2016 4:00 pm UTC 90 mins
    • The JOBS Act and more recently the FAST Act have brought about a number of changes to the framework governing offerings exempt from SEC registration. More and more US and non-US companies are choosing to rely on securities offerings that are exempt from the US registration requirements. In part as a result of these and other changes, there are now more sources of private capital and “restricted securities” have become more liquid. As a result, many more promising companies are choosing to defer their IPOs and rely on exempt offerings to fund their growth. We will discuss the following:

      How the JOBS Act has affected private placements;
      Late-stage private placements;
      The Regulation A market;
      The final crowdfunding regulations;
      Other exempt offering developments, such as intrastate offering changes; and
      Resales of restricted securities through private secondary market transactions as well as reliance on new Section 4(a)(7).

    • The Future of Data Centre Cooling? - 3M's Open Bath Technology The Future of Data Centre Cooling? - 3M's Open Bath Technology Phil Tuma, 3M Electronics Recorded: Jan 10 2012 11:00 am UTC 46 mins
    • The limitations of legacy air cooling schemes are by now well known. Even the latest free-air cooling technologies have limitations relating to primarily to power density and energy efficiency. While emerging technologies such as direct water cooling can dramatically increase efficiency, density and the thermodynamic availability of waste heat, these approaches add complexity, cost and risk that the commodity datacom industry may be unwilling to bear. Recently published work has suggested the utility of a new cooling strategy termed open bath immersion cooling for datacom equipment. In this simple concept, servers are immersed side-by-side in bath of nonflammable dielectric liquid that boils off the heat generating devices. The vapor so generated condenses on a coil cooled by facility water and passively falls back to the bath. The process takes place within modular semi-open baths, so-called because they are closed when access is not needed but operate at atmospheric. Power densities as high as 4kW/liter have been demonstrated with densely packed modules that simulate CPU packages. This presentation will include an overview of research to date including a comparison to existing pumped water systems and an introduction to a system-scale project currently in the proposal stage that would demonstrate the commercial viability of the technology.
      Phil Tuma is an Advanced Application Development Specialist in 3Ms Electronic Markets Materials Division in St. Paul, Minnesota USA. He is currently working to demonstrate the utility of passive 2-phase immersion for cooling power electronics and datacom hardware.

    • Next generation carbon capture technologies for coal Next generation carbon capture technologies for coal Toby Lockwood Recorded: Apr 27 2016 11:00 am UTC 38 mins
    • Established CO2 capture technologies such as absorption with amine solvents are associated with significant energetic and economic penalties, reducing power plant efficiency by around 10% points and increasing the cost of electricity production by up to 80%. Dedicated research programmes worldwide have pursued the development of a wide range of innovative, alternative technologies for CO2 capture, largely by addressing the fundamental gas separation step at the heart of post-combustion, pre-combustion or oxyfuel combustion processes. Novel solvents with lower energy requirements than conventional amines, using phase change systems, ionic liquids, enzyme-activation, or non-aqueous solvents, are promising approaches for post-combustion capture. Alternatively, techniques used in other commercial gas separations, including solid sorbents, membranes, and cryogenic separation, have also been developed for carbon capture through extensive materials research and process optimisation. Whilst challenging for post-combustion capture applications, these techniques may be of particular benefit to pre-combustion capture systems where much higher partial pressures of CO2 are available, and integration of the CO2 capture step and water gas shift reaction can be achieved using sorbents or membranes. In oxyfuel combustion, membranes are also an option for efficient oxygen production, but pressurised combustion systems have demonstrated the most potential for efficiency improvements, potentially in combination with novel power cycles which are better-suited to exploiting the altered combustion conditions. Finally, chemical looping combustion is a unique approach to carbon capture which can achieve dramatic energy savings through its inherent avoidance of any gas separation step, and is undergoing significant scale up. This webinar will review these developments in novel capture technologies and highlight the most promising strategies for achieving major cost reductions.

    • Enabling Reliable Compound Identification using LC-MSn Enabling Reliable Compound Identification using LC-MSn Herbert Oberacher Recorded: Nov 10 2015 3:00 pm UTC 53 mins
    • Enabling Reliable Compound Identification using LC-MSn

      Reliable compound identification with non-targeted liquid chromatography-tandem mass spectrometry (LC-MS/MS) is a major challenge. It involves matching against reference data. For fast and automated identification, tandem mass spectral libraries are queried with appropriate search tools. Reliability of search as well as time and efforts spent for data reviewing very much depend on the quality of the database involved. In this presentation, we will give an overview on our efforts towards the development of a reliable, robust, and transferable tandem mass spectral database, and how such a database can successfully be implemented in workflows for comprehensive drug analysis.

    • White Space 22: Aftermath White Space 22: Aftermath Peter Judge, Max Smolaks, Bill Boyle, Cole Crawford Recorded: Nov 26 2015 6:00 pm UTC 17 mins
    • This week on White Space, we look back at the news from DCD Converged conference in London. We’ve also brought back a special guest - Cole Crawford, CEO of Vapor IO and purveyor of unusual rack arrangements.

      We discuss various ways to reuse server heat and discover that Coca Cola is apparently using Internet of Things to develop new flavors of the sugary drink.

      Peter looks at the reasons behind the Telecity outage in the UK - but this outage has nothing on the recent data center fire in Azerbaijan, that left almost the entire country without access to the Internet.

      Also mentioned are the news about CA Technologies getting out of the DCIM business, the reinvention of liquid cooling company Iceotope and the fact that the US government has just discovered another 2000 data centers it didn’t know it had.

    • Challenges and opportunities for coal gasification in developing countries Challenges and opportunities for coal gasification in developing countries Dr Andrew Minchener Recorded: Jan 8 2014 12:00 pm UTC 44 mins
    • Coal gasification for chemicals, gaseous and liquid fuels production can fulfil an important strategic need in those developing countries where coal is the primary fuel source and oil and gas energy security is an issue. At the same time, the establishment of major projects in such countries can be problematical for a number of technical and economic reasons, although it is encouraging that some projects appear to be moving forward. There are two developing countries where coal conversion projects to produce chemicals, gaseous and liquid fuels have been taken forward strongly. The first is South Africa, which established the world’s only commercial-scale coal-to-liquids and coal-tochemicals facilities at Secunda and Sasolburg respectively. The other is China, where there is a major gasification-based coal conversion development and deployment programme that is set to become a significant, large-scale commercial element in the nation’s energy development plans. This will provide further major opportunities for the deployment of large-scale coal gasification technologies, various syngas conversion units and catalysts for the subsequent production of the required products. The role of China is likely to be critical in the dissemination of such technologies to other developing countries as it can not only provide the technical expertise but also financially underpin such projects, including the associated infrastructure needs.
