A report describes a pulse tube refrigerator that uses a mixture of 3He and superfluid 4He to cool to temperatures below 300 mK, while rejecting heat at temperatures up to 1.7 K. The refrigerator is driven by a novel thermodynamically reversible pump that is capable of...

A document discusses the creation of a viewport suitable for use on the surface of Venus. These viewports are rated for 500 °C and 100 atm pressure with appropriate safety factors and reliability required for incorporation into a Venus Lander. Sapphire windows should easily withstand the chemical, pressure, and...

A document discusses a simulation chamber that represents a shift from the thermal-vacuum chamber stereotype. This innovation, currently in development, combines the capabilities of space simulation chambers, the user-friendliness of modern-day electronics, and the modularity of plug-and-play computing. The Mobile Chamber is a...

A document highlights a means to complement remote spectroscopy while also providing in situ surface samples without a landed system. Historically, most compositional analysis of small body surfaces has been done remotely by analyzing reflection or nuclear spectra. However, neither provides...

A document discusses power converters suitable for space use that meet the DSCC MIL-PRF-38534 Appendix G radiation hardness level P classification. A method for qualifying commercially produced electronic parts for DC-DC converters per the Defense Supply Center Columbus (DSCC) radiation hardened assurance...

RNA isolation is a ubiquitous need, driven by current emphasis on microarrays and miniaturization. With commercial systems requiring 100,000 to 1,000,000 cells for successful isolation, there is a growing need for a small-footprint, easy-to-use device that can...

The utilization of ultraviolet resonance Raman spectroscopy for the detection and identification of chemical, biological, and nuclear hazards is of great interest due to the sensitivity and specificity afforded by this technique. Detection by means...

Medical Design Briefs News Online is kicking off Breast Cancer Awareness Month with new optical imaging technology developed at Tufts University School of Engineering, Medford, MA, that may provide doctors with new ways of both identifying breast cancer and monitoring individual patients' response to initial...

Asthma? There’s an app for that. Currently, those who suffer from asthma or other chronic lung problems only get a measure of their lung function at the doctor’s office a few times a year by blowing into a specialized piece of equipment – the spirometer. But, more frequent testing at home could detect...

Researchers at the University of Illinois (UI), Champaign, in collaboration with Tufts and Northwestern universities, have created a new class of electronic devices: biocompatible and biodegradable electronics for medical implants that can dissolve completely in water or in body fluids. “We refer to this type of...

Is your company developing a medical product that could help solve a health or human performance challenge in space? Have you developed a biomedical product for the space program that could also improve health on Earth? The National Space Biomedical Research Institute’s (NSBRI) Industry...

Robotic surgery though the mouth is a safe, effective way to remove tumors of the throat and voice box, according to a study published in in the journal, Head and Neck, by surgeons at the Ohio State University Comprehensive Cancer Center, Columbus, OH, Arthur G. James Cancer Hospital and Richard J....

For a skilled surgeon performing general surgery, tiny hand tremors are usually not a serious risk for patients. But what if the surgeon is operating inside the human eye or repairing microscopic nerve fibers? Scientists from the Johns Hopkins University Whiting School of Engineering and Johns Hopkins...
