Waschmittel aus Sand: Wissenschaftler der Uni Kassel entwickeln neuartiges umweltfreundliches Tensid

Es klingt wie ein Zaubertrick: Eine Forschungsgruppe der Universität Kassel hat auf Basis von gewöhnlichem Quarzsand eine neuartige Klasse von Tensiden entwickelt. Der Stoff kann in Seifen oder Waschmitteln zum Einsatz kommen und hat gegenüber herkömmlichen Produkten eine Reihe von Vorteilen.

Der Stoff hat einen komplizierten Namen, aber er hat, was es im Haushalt braucht: Das „silanol-basierte Tensid“, das Wissenschaftler der Universität Kassel entwickelt haben, vereint wie herkömmliche Tenside Flüssigkeiten, die eigentlich nicht mischbar sind, und löst so beispielsweise das Öl von der Küchenschürze im Wasser der Waschmaschine. „Unser silanol-basiertes Tensid reduziert die Oberflächenspannung von Wasser in vergleichbarem Maße wie andere bekannte Tenside“, erklärt Prof. Dr. Rudolf Pietschnig, Leiter des Fachgebiets Chemische Hybridmaterialien an der nordhessischen Hochschule. Damit könnte der Stoff im Prinzip zukünftig als Kernbestandteil von Waschmitteln, Seifen, Spülmitteln und anderen Detergenzien zum Einsatz kommen. (more…)

How patients make medical decisions

ANN ARBOR — Sooner or later, everyone faces decisions about whether or not to have surgery, take a new medication or have a cancer-screening test.

A new University of Michigan study published in Health Expectations explores the costs and benefits patients say are important in making these kinds of medical decisions, and how those costs and benefits explain what they actually decide to do. (more…)

Online Design: Novel Collaborative Software Helps Systems Engineers Link Performance and Cost

Today’s modeling and simulation (M&S) software provides indispensible tools for systems engineering challenges. Such programs allow investigators to experiment with “what-ifs” by adjusting design parameters and examining potential outcomes.

A team from the Georgia Tech Research Institute (GTRI) has produced an advanced web-based tool that lets physically separated participants collaborate on model-based systems engineering projects. Known as the Framework for Assessing Cost and Technology (FACT), the program utilizes open-source software components to allow users to visualize a system’s potential expense alongside its performance, reliability and other factors.

The cost of emergency care: Emergency care cost estimates are too low

U.S. emergency care costs may be more than twice previously published estimates, according to a new analysis that critiques those estimates, argues for improved accounting, and suggests considering the value of emergency care as well as total spending.

PROVIDENCE, R.I. [Brown University] — Alternately praised in the aftermath of horrible tragedies as a heroic service and lamented in policy debates as an expensive safety net for people without primary care, emergency medicine is often a hot topic. Despite that importance, an analysis published online April 26 in the Annals of Emergency Medicine finds that national expenditures on emergency care are likely significantly higher than previously thought.

“The ER has become increasingly important as a place where people go for acute unscheduled care, however there has been little rigorous analysis of its cost structure,” said paper lead author Dr. Michael Lee, assistant professor of emergency medicine in the Warren Alpert Medical School of Brown University and a physician at Rhode Island Hospital and The Miriam Hospital.

New device could cut costs on household products, pharmaceuticals

Sometimes cost saving comes in nanoscale packages.

A new procedure that thickens and thins fluid at the micron level could save consumers and manufacturers money, particularly for soap products that depend on certain molecules to effectively deal with grease and dirt. Researchers at the University of Washington published their findings online April 9 in the Proceedings of the National Academy of Sciences.

Read the back of most shampoos and dishwashing detergents and you’ll find the word “surfactant” in the list of active ingredients. Surfactant molecules are tiny, yet they are the reason dish soap can attack an oily spot and shampoo can rid the scalp of grease. (more…)

Software Piracy Costs Billions in Time, Money for Consumers and Businesses

New Microsoft-commissioned study also highlights dangers for those that use counterfeit software.

REDMOND, Wash. — Although some computer users may actively seek pirated software in hopes of saving money, the chances of infection by unexpected malware are one in three for consumers and three in 10 for businesses, according to a new study commissioned by Microsoft Corp. and conducted by IDC. As a result of these infections, the research shows that consumers will spend 1.5 billion hours and US$22 billion identifying, repairing and recovering from the impact of malware, while global enterprises will spend US$114 billion to deal with the impact of a malware-induced cyberattack.

The global study analyzed 270 websites and peer-to-peer networks, 108 software downloads, and 155 CDs or DVDs, and it interviewed 2,077 consumers and 258 IT managers or chief information officers in Brazil, China, Germany, India, Mexico, Poland, Russia, Thailand, the United Kingdom and the United States. Researchers found that of counterfeit software that does not come with the computer, 45 percent comes from the Internet, and 78 percent of this software downloaded from websites or peer-to-peer networks included some type of spyware, while 36 percent contained Trojans and adware.

September 11 and The Cost of War

The Costs of War project is assessing the total cost of the conflicts in Iraq and Afghanistan in the wake of the 9-11 attacks. Findings thus far put the cost at more than 300,000 lives and $4 trillion. The project’s findings are continually updated. (more…)
