Making Injection Molding More Energy Efficient

Thin-film heating can improve the quality of plastic parts. In the future, thin-film heating will allow plastic parts to be produced with greatly improved surface quality. Researchers at the Fraunhofer Institute for Mechanics of Materials IWM, Freiburg, Germany, say they have found a way to make the whole process more energy efficient.

Using Molded Foam Makes Assembly a Snap

Today, medical devices are made using a variety of plastic materials and manufacturing processes. Advances in plastic processing make it possible to obtain virtually any shape, form, or function. In addition, the vast assortment of plastics available allows designers to design for the optimal balance of functionality, performance, and cost. Expanded polypropylene (EPP) is a plastic material that is starting to gain traction in the medical device market as product designers become more familiar with the multiple benefits it can provide.

Updated Facts on 2015 HCFC-225 Usage Ban

Beginning January 1, 2015, HCFC-225, a common precision solvent for high-end cleaning, will be banned for usage. How will this affect end-users? In 1974, Sherwood Rowland and Mario Molina discovered that chlorofluorocarbons (CFCs) were depleting the ozone layer, and in 1995, they received the Nobel Prize in Chemistry for this work. In response, the United Nations Environment Programme called an international conference to discuss the issue. Shortly thereafter, the US banned all non-essential uses of CFCs as propellants in aerosols. The Montreal Protocol required all developed countries to begin the phase-out of CFCs in 1993 and reduce CFCs to 50% of the baseline by 1998. A timeline for the phase out of hydrochlorofluorocarbons (HCFCs) was created in 1997. To meet the 90% total reduction requirement for all HCFCs by 2015, HCFC-225 is now being phased out.

Diagnosing Wrist Problems in Motion with MRI

“Active-MRI” could diagnose wrist problems sooner. Moving images could be invaluable when it comes to diagnosing wrist problems say a group of researchers at University of California-Davis. The multi-disciplinary team of radiologists, medical physicists, and orthopaedic surgeons say that they have found a way to create “movies” of the wrist in motion using a series of brief magnetic resonance imaging (MRI) scans. Called “Active-MRI,” the technique could be used to diagnose subtle changes in physiology that indicate the onset of conditions such as wrist instability.

Assessment of Microbial Bioburden Within Aerogel Matrices

A post-capture aerogel degradation via cryogenic grinding is compatible with downstream nucleicacid- based molecular modes of analysis. A makeshift apparatus has been designed composed of a sealed, hydrophobic 2-propanol/SiO2 aerogel component to filter outside air particles. Following verification and assessment, the apparatus was crafted with a Buchner funnel. Aerogel matrices were tightly fitted into filter housings and secured in side-arm flasks, which were then equipped to a vacuum pump to pull air through the aerogel matrices. Aerogels, both with and without fiberglass reinforcement, were used to collect airborne particulates for one- and three-hour increments. An untreated negative control aerogel, employing air collection from a laminar hood, and a positive aerogel matrix were seeded with endospores that verified the extraction from the matrices.

Telemedicine Robots Bring Expertise to Remote Areas

There was a time telemedicine meant holding a heartrate monitor up to the phone receiver to play an audible signal. Modern telepresence robots like the RPVita from InTouch Health do more than put a patient’s diagnostic information in the hands of an offsite doctor, they create a virtual presence that allows physician and patient alike to have an experience startlingly close to the real thing (see figure 1). With sophisticated controls, advanced imaging, and small, quiet FAULHABER DC motors from MICROMO, InTouch brings top-flight medical care to the farthest reaches of the globe.
