Industrial Furnace With Flameless Combustion and Impingement Flow for Increased Efficiency, Reduced Emissions and Intensified Heat Transfer

An assistant professor of mechanical engineering technology and inventor from the University of Wisconsin Oshkosh has developed an industrial natural gas furnace and oven design that combines flameless combustion with high velocity impingement gas and air jets directed toward the product being heated. This novel combination has the potential to provide advantages over conventional technology that include higher energy efficiency, uniform temperature distribution, reduced NOx emissions, and intensified convection heat transfer. The design also has the potential to increase productivity by allowing more material to be processed within the same combustion area. This innovative system can be used for production of new furnaces as well as retrofitting existing installations.

Low Maintenance Snowmobile Ski Design that Increases Traction, Maneuverability and Safety on Paved Surfaces

Students from the University of Wisconsin-Green Bay in partnership with UW-Platteville Senior Design have developed a snowmobile ski that offers improved steering and traction on pavement and other hard surfaces. The design incorporates a fixed wheel and runner system, which provides steering control when rolling on pavement and concrete yet allows the skis to function properly when driving on snow and ice surfaces. The design has been refined through multiple prototype iterations and has passed testing for mobility on hard surfaces, traction on ice, and functionality on snow. The present design increases maneuverability on pavement and requires less maintenance when compared with snowmobiles that are currently on the market.

Modified Newton’s Cradle Demonstrating Mechanical Impedance

A Physics professor and inventor at the University of Wisconsin – Whitewater has developed a modified Newton’s Cradle that allows the user to visualize and test the concept of mechanical impedance in addition to momentum and energy conservation. The traditional version of Newton’s cradle has a cradle of identical metal spheres. In this modified and improved device, the user is able to interchange these spheres with ones of varying mass and material composition. By allowing the user to strategically align and create a unique cradle, they have the opportunity to visualize mechanical impedance. For example, a sphere with a small mass would have the ability to strike the cradle and lift a sphere of greater mass on the opposite side if the spheres in-between had a gradient of increasing mass themselves. The possibility of changing a sphere at any position in the cradle allows for an exceptionally large number of possible experiments and would overall lead to an enhanced understanding of the aforementioned physics concepts, something a traditional cradle device does not provide for.

Novel Transparent Dilatant Materials Comprised of Single Chemical Component

Research from the University of Wisconsin-Stevens Point has resulted in the synthesis of a series of materials exhibiting a range of dilatant properties. The materials show good transparency and are chemically uniform (e.g. consisting of a single chemical component). The degree of dilatancy is easily controlled by adjusting the compositions of the materials. Due to the range of dilatant properties, good transparency, and single chemical component nature of the dilatant samples, these materials show significant promise for novel uses in protective equipment and other areas related to impact protection, especially where transparency is desirable.

Nylon-3 Polymers to Treat Fungal Infections

UW–Madison researchers have found that nylon-3 polymers developed in their lab display potent antifungal activity against a broad spectrum of common fungal pathogens, with minimal toxicity towards mammalian cells. The polymers have some activity alone, and when used in combination with existing drugs provide synergistic effects against Candida albicans, Cryptococcus neoformans and Aspergillus fumigatus strains, including some resistant strains.

Synergistic combination offers efficacy with significantly reduced amounts of drug and corresponding toxicity, which could potentially expand the relevant patient population.

The polymers were designed to resemble host-defense peptides (HDPs), which are natural molecules that exhibit antimicrobial activities.

Creating ‘Designer’ Yeast Hybrids for Brewing and More

UW–Madison researchers have developed HyPr, a simple and efficient method for generating synthetic Saccharomyces hybrids without sporulation or modification of the nuclear genome.

Specifically, using the new method, induction of HO endonuclease expression by a promoter in two diploid cultures, followed by co-culture and subsequent double-drug selection, will produce hybrids at a rate approaching 1 out of 1,000 cells plated. Plasmids can then be easily cured or spontaneously lost to produce strains without genome modifications.

The resulting strains can be rapidly screened for plasmid loss, opening an efficient route towards meeting the Generally Recognized as Safe (GRAS) standards of the U.S. Department of Agriculture and FDA.

Analogs of Diptoindonesin G for Breast Cancer Drug Development

UW–Madison researchers have synthesized analogs of Dip G that have shown a greater ability than the parent molecule to decrease ERα expression and stabilize ERβ in cultured breast cancer cells. The compounds are active for ameliorating, attenuating and halting the growth/metastasis of breast cancers.
