For decades our data center owners and operators have feinted at the thought of water and liquids in the data center. But, it is already happening in many data centers and has been for some time in some facilities. What are the different technologies available to data centers today? Where can they best be used? Which ones are best suited for which environments? When can we expect to see them in our data centers? Bruce will discuss the “ins and outs” of liquid cooled technologies yesterday, today and tomorrow. Get ready for some surprises in the process.Read more >
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.Read more >

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.Read more >
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.

Ionic liquids (ILs) and their components have had a substantial impact on the capabilities and performance of gas chromatography, ESI-MS and MALDI-MS. For GC this ranges from the analysis of complex mixtures by GC x GC, water quantitation and food/beverage analysis among other areas. In MS the most sensitive analysis of anions, phospholipids and metal cations is often done by ESI-MS using complex IL cationic reagents. Also the best MALDI matrices for many proteins, peptides, carbohydrates and synthetic polymers are based on ILs. These will be discussed as time permits.Read more >
In this webinar, Professor Peter Schoenmakers will provide insight into the various LC techniques, including:
* An overall perspective of current usage and applications of the various techniques.
* A description of how the techniques developed, starting from paper chromatography up-to current "high tech" two-dimensional separations.
* A more detailed focus on the concept of various methods.
Often portrayed more as magic than science, popular television series such as CSI have aroused great interest in analytical chemistry. Forensic science relies on separation science.
Peter Schoenmakers' webinar will also, in a light-hearted manner, put LC methods into the correct perspective for forensic science.

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 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-openÂ 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.
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.Read more >
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.

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.Read more >
