Solutions for Today



Mr. McGuire: “I want to say one word to you. Just one word.”

Benjamin: “Yes, sir.”

Mr. McGuire: “Are you listening?”

Benjamin: “Yes, I am.”

Mr. McGuire: “Plastics.”

Benjamin: “Exactly how do you mean?”

Mr. McGuire: “There’s a great future in plastics.”

Of course every article that even comes close to mentioning plastics quotes that fabulous scene between Benjamin and Mr. McGuire in the 1967 film, The Graduate. It’s too good to ruin the tradition. If you’ve never seen it and/or are too young to have ever heard about the film, go see it.

Though the scene was intended to show the differences between the generations, Mr. McGuire’s advice was spot on. Today, in the United States, the plastics industry is extremely successful and the future outlook remains strong. Plastics are found in nearly everything we use, such as bottles, food trays, squeeze bottles, grocery bags, trash bags, food storage bags, just to name a few of what we use.

Believe it or not, plastics is actually a science, just like physics and chemistry, and engineers, researchers, and developers earn degrees and dedicate their careers to its study and development.

Some plastics contain toxins and some are not biodegradable. So, many scientists dedicate themselves to improving plastics. High density plastic or High Density Polyethylene (HDPE) is considered a low hazard plastic, which is less toxic and more biodegradable.

The Use Of High-Density Thermoplastic Material Formulations In Diverse Applications


, , ,

High Density thermoplastic material formulations are currently being used for lead replacement for health, safety, and environmentalconcernsandto increase part density without using metals.

High-density Thermoplastic formulations provide a high specific gravity and afford a significant advance in part mass without metal’s design limits, costs, and complicated processing. Put it in place of conventional plastic and it’ll add weight and mass for higher quality, all while maintaining the same part design and volume.

Lead Replacement For Health, Safety, And Environmental Concerns

Health, safety, and environmental concerns are increasing the need for lead replacement. Just consider what’s happened lately with Detroit and its drinking water and you get the idea. Initially, lead poisoning can be difficult to distinguish. Those with high blood levels can seem healthy. Symptoms don’t usually appear until dangerous blood levels accumulate. Those symptoms include irritability, loss of appetite, abdominal pain, seizures, and hearing loss.

Engineers can structure High-Density Thermoplastic Material to be non-toxic and use it as a lead replacement. Designers are now using high density polymer formulations in radiation shielding for nuclear medicine, X-ray equipment, and in non-toxic ammunition.

Increase Part Density Without Using Metals

There is also a need to raise part density without using metals. The polymers in High-Density Thermoplastic materialcompounds have certain properties that influence mold design and additives that boost the matrix’s thermal conductivity. They don’t need unusual cooling systems and in certain situations, cooling time can be lessened.

Injection molding is the most common technique for handling high-density thermoplastic formulations. They offer many useful advantages, including the ability to add weight and balance.

Plastic Compounds Replace Lead In Radiation Shielding


, , ,

In 2006, the European Union adopted the Restriction of Hazardous Substances Directives, which the European Union and many other countries followed, including the United States. It called for suitable lead replacements in medical devices. Lack of appropriate substitutes allowed for extensions and many companies are working on developing suitable alternatives.

For decades, lead was the standard in radiation shielding. It was inexpensive, simple to process, and successfully offered protection. Lead, however, is toxic. No one wants to be near or around it anymore. Radiation, of course, isn’t good either. So, what offers sufficient lead replacement?

Many companies are developing high gravity, high-density metallic-filled polymers. Original equipment manufacturers want the new components to look and feel like lead. Such compounds are effective radiation shielding materials that are also cost-effective. As well, they’re pliable and practically eliminate the secondary operations that lead usually requires.

Improving Through Engineered Thermoplastics


, ,

All around the world, people are becoming more environmentally conscious. Many cities around the world and in the United States are developing bicycle ride share programs. People are encouraged to use the bicycles, instead of taxis, public transportation, or cars. The response in certain cities has been extremely positive and many residents are enjoying biking around to work and social events.

All the riding is also placing a strain on the bikes. Earlier this year, China, whose program is really successful, sought a way to make a tougher tire as the air-filled ones on their bicycles were suffering terribly. Engineers are going to experiment with engineered thermoplastics utilizing composite materials and attempt to create a better tire.

Some of the bikes are now a solid tire designed with a rubber-polyurethane foam blend while others a solid tire designed with thermoplastic elastomers. The polyurethane foam tires reduced the bike weight and improved shock absorption and resilience.

Such is really just one way a designer can use engineered thermoplastics.

Toxic Free Radiation Protection


, ,

The idea of radiation might conjure thoughts of nuclear bombs, but, actually, radiation is all around us. It’s in our microwave ovens, our radios, and it even develops from the earth. Not to worry, though. radiation is simply energy that travels space as high-speed particles or waves.

There has been a proliferation of important technology which produces radiation as a by product of its use, and as such it’s important to understand proper radiation shielding safety. Most of us are familiar with x-rays, MRIs, and CT scans. They all use radiation to perform their tasks. The tests certainly help physicians, but exposure can cause damage to our tissue and DNA, so we need some form of protection, as do the individuals who conduct the tests. There are also individuals who work in plants and factories where radiation is utilized. They require protection, as well.

Protection is broken down into the following categories:

• Time: the body absorbs radiation, so individuals are advised to minimize their exposure.

• Distance: proximity determines exposure, so individuals are advised to maintain a certain distance.

• Contamination: spills need to be isolated using strict procedures and guidelines.

• Shielding: individuals working near radiation need to use proper protection, including glasses, gloves, and aprons.

New Research Could Allow Frangible Projectiles to Disintegrate After Designated Distance


, ,

Frangible ammunition is pretty much the same than any other ammunition, with the key difference being that it uses a copper jacket instead of a lead core. The bullet is designed in such a way that when it hits a target harder than itself at full speed, it crumbles into pieces.

While this type of ammunition is expected to reduce the risk of collateral damage as the fragments are too small to cause any major harm, one of the biggest issues with frangible projectiles, and all other types of bullets for that matter, is that stray shots can often pose serious collateral damage, severe injury, and in some cases, even death.

Turns out a new research could soon be changing how the world looks at frangible bullets. Ernesto Marinero, professor of materials engineering, recently led a research group that has come up with a new range of frangible bullets which become non-lethal and completely disintegrate after traveling a particular distance, whether or not they hit an object.

The technology combines a limitation of range to the shrapnel-eliminating features of Frangible bullets and the stopping power of normal ammunition to limit the bullet’s range.

These frangible projectiles could drastically reduce the risk of injury and collateral damage, making such bullets even more preferable in sectors such as range shooting, law enforcement and military. The bullets have been patented by the Office of Technology Commercialization at the Purdue Research Foundation and can be licensed by companies.

Lead Aprons Could Be Block Radiation Exposure at the Cost of Lead Poisoning



Radiation refers to cancer-causing energy that is transmitted in the form of high-speed particles or waves by the sun. Humans make use of man-made radiation in nuclear power plants, cancer treatments and x-ray devices, and have traditionally depended on radiation shielding materials such as lead aprons to protect them from radiation exposure.

While lead aprons might be a great way of protecting against radiation exposure, it turns out that they also increase the chances of lead poisoning for those who use and work with these aprons. And considering that even low level exposure to lead can be toxic for both children and adults, it might finally be the time to permanently switch to lead-free shielding materials.

The Study

A study published in the Journal of the American College of Radiology seems to confirm this line of thought. Jamie Shoag, MD at NYU Langone Medical Center and Kevin Burns, MD at Montefiore Medical Center, tested 172 lead shields that were used for fluoroscopy and x-ray at an academic medical center in NYC. They found that more than 50% of the shields had lead dust on the surface.

The Testing Method

Each shield was tested for external lead dust via the Flame Atomic Absorption Spectrometry (FAAS), a quantitative dust wipe analysis conducted in the lab and a qualitative on-site test. Researchers also used the chi-squared test to determine the association of lead present on the surface of the shield with factors such as sheet thickness, the type of shield, age, radiographic appearance and storage method.

The Results

The presence of lead was detected to be around 63% using the FAAS method and around 50% using the qualitative method. The dust detected ranged between untraceable quantities to 998 micrograms per sq. foot.


Having chosen the right upper quadrant area for qualitative analysis and the middle area for quantitative analysis, the authors conceded that these areas might not represent the exact level of lead dust on the entire surface of the shield. “We did attempt to mitigate this limitation by performing a four-quadrant analysis on a subset of shields, which showed consistent results in all locations,” they state.

Even so, these findings prompted authors to urge all imaging centers and departments to switch to lead-free shielding materials as soon as possible. While it has been acknowledged that a single-site sample might have posed limitations to the study’s results, this was the first study of its kind and a standardized protocol for testing these shields is yet to be developed.

What Lies Ahead?

The authors have already called for more research to determine the clinical impact of these findings and further studies might shine some light on the limitations and dangers posed by existing x-ray and radiation shielding materials.

Blood levels could also be monitored to determine whether lead was transferred into the body while hand wipes could be a great way of determining if lead dust was transferred from lead aprons to the hands and bodies of technicians, physicians and nurses.

Floor Vibration Control Could Help Design Quiet Nano-Tech Facilities



Reducing floor vibration is essential for patterning and imaging industries that work at the sub-nanometre level. As experts move towards smaller scales for pin-point accuracy and more sophisticated solutions, the need for vibration damping and acoustic dampening solutions is now more than ever.

A number of instruments need to achieve extremely precise measurements and the highest of resolutions. For example, electron microscopes need resolutions that range from the sub-nanometer to the tens of nanometres. Yet other microscopes work with resolutions in the sub-Angstrom levels. Floor vibration often causes a hindrance for these tools as it prevents them from achieving their design specifications.

The Quiet Building Concept and its Limitations

To overcome such issues, architects bank on the concept of ‘quiet buildings’, where Vibration dampening and acoustic dampening materials are used to reduce vibration levels without causing too many complexities in design. However, while these buildings offer moderate vibration damping solutions, nano-tech facilities generally need to meet extremely low vibration specification levels, and this significantly increases the cost of constructing the facility.

Another hindrance to the concept of ‘quiet buildings’ is that even though the floors are made using Vibration damping material, the moment you add other machinery and people into the building, vibration negates any benefit that the quiet building design has to offer.

The Quiet Island Concept

New data shows that creating quiet islands at several locations within the facility can truly help the facility achieve the low vibration requirement of nano-tech facilities. The concept focuses on placing a damped, rigid platform that matches the footprint left by the instrument and is ably supported by active acoustic dampening and vibration cancelling systems at locations where precision instruments are located and in locations where experiments and research is expected to be conducted. To do so, architects replace a section of the access floor with an isolated foundation that has been mounted to the sub-floor in order to prevent sub-floor vibrations from reaching the devices.

Benefits of Creating a Quiet Island

One of the main benefits of creating quiet islands is that the technique offers an extremely quiet surface, thereby creating a mini-environment, oases within the facility that are free of vibration. It becomes easier to make these quiet islands meet the cleanliness requirement of nano-tech facilities and rather on focusing on clean rooms and vibration proof rooms, the focus soon turned to clean islands and vibration proof islands, thereby reducing costs and increasing efficiency.

The quiet island concept also helps overcome the vibration caused when people and machinery are introduced into the facility. The approach is to arrange low frequency inertial vibration sensors in 3 axes in order to determine the level of vibration. The signals pass through advanced controllers and high capacity piezoelectric actuators to prevent any floor motion from reaching the isolated surfaces of the quiet island.

The quiet island concept comes as a boon to advanced semiconductor factories and chip-makers. Researchers at advanced electron microscope and imaging centres and nanotechnology research centres can also benefit from the quiet island concept.

The Benefits of Frangible Bullets


, ,

Frangible bullets is coming up as the modern-day bullet, the bullet of choice for personal defence and shooting. But what exactly does this bullet has to offer? To start with, it is made with a compressed material, usually copper, tungsten or zinc, and is therefore completely free of lead.

Testing the Frangible

From shots on paper targets to steel plates to live hunting action, frangible bullets have been tested on everything, and excelled at everything. Hunters have ably dropped game with frangible bullet, confessing their love for its ability to offer clean kills and devastating wounds. Better yet, using frangible bullets saves the environment from lead poisoning, and most hunters and bald eagle lovers are now beginning to realize that we’ve had enough of that. Another benefit of a frangible bullet is the absence of an exit wound, which drastically reduces the chances of unintentional injuries due to over penetration.

Steel plate shooting is considered to be the best use of Frangible ammunition. There is that distinct ‘ping’ when the bullet hits home, but the sound is more subdued than non-frangibles hitting steel. Better yet, there isn’t the slightest backsplash nor any chance of a ricochet.

Reducing Accidents

Frangible bullets are designed to shatter into tiny pieces upon impact, offering greater penetration and reducing the chances of accident or unintended injury. The ability to shatter upon impact prevents ricochets and also stops the bullet from penetrating through a soft target with significant force. And while these are some excellent benefits that frangible projectiles have to offer, there are some other benefits of using frangible bullets as well.


Most shooters would like to believe that since frangible projectiles are lightweight, they cannot be as accurate as ordinary bullets. However, when tested at distances ranging from 7 to 25 yards, frangibles offered the same, if not better, levels of accuracy. Moreover, frangible bullets even offered great results when it came to precision, i.e., that tight group right where you want it to be.

Multi-Purpose Use

And while frangible bullets are ideal for steel plates, they offer a far greater variety of uses. Their ability to penetrate the body and cause permanent would cavities means that they’re equally useful for self defence or hunting. They’re entirely capable of devastating internals and shattering bones, and they often tend to drop the target quickly and painlessly.

Frangible bullets are sure to drop and drift differently when compared to non-frangibles, but don’t let that stop you. There’s nothing that a little bit of practice can’t correct. As with any ammunition, spending some time at the range helps you determine the right aim.
