Creating Diamond-like Carbon Coatings

Written by: Denton Vacuum, LLC

Diamond-like carbon coatings can be created in a laboratory.

Diamond like carbon coatings can be deposited in a variety of ways using different methods. Some of these methods include: ion beam, electron beam, lasers, and sputter coating.

The Coating Process

The entire coating process takes place in a specially designed vacuum chamber that varies by system. Some of the more optimal systems utilize a fixated carousel that the vacuum lies on. The source material is then preheated to a specific temperature, typically less than 150 degrees Celsius. During the preheating process, the substrate that is going to be coated is rid of all of the moisture produced by the material utilizing the vacuum attached to the sputter coater. The adhered moisture can affect the product’s properties as well as the final result.

The next phase requires there to be a scrubbing of the surface with ions to enhance the overall adhesion and scatter. Once the cleaning process has completed, an optional gas is added into the chamber which then transitions into the coating step. Finally, the electrical charge created by the carousel then draws the hydrogen and carbon ions to the surface therefore creating the thin film layer. The carousel can also rotate to improve the uniformity and prevent any thin film evaporation from occurring on the final product.

The Final Product

Diamond like carbon coatings are high quality films that surpass the conventional plating methods used regularly. By redefining the film’s properties like hardness and structure, one can expect a uniform film that is optimal for various applications.

Quality

Check their certifications to see if they are qualified to work with. ISO9001 certified is the standard that you should be looking for. If your modified oligo comes to you in an altered state, there would be no reason for them to refund it. Be sure that they provide quality products at a fair price as well. You may also check to see if they have comprehensive quality control reports.

Summing It Up

Find a reputable company that offers oligos that are flexible enough to offer you various DNA synthesis scales at a competitive price. It’s important that you perform adequate research to avoid wasting both your time and money.

Alfred Mann Foundation Creates Amazing Robotic Hand for Retired Denver Marine

The biggest challenge for those who lose limbs through amputation or trauma is that life never really returns to a sense of normalcy. If you lose a leg, going for a run feels like a luxury. Losing your sight or your hearing can completely change how you interact with the world around you.

This harsh reality was daily routine for James Sides, a retired Staff Sergeant from Colorado. During his second tour of Afghanistan, Staff Sergeant Sides encountered an IED. Trained in disposal, Sides went to work on clearing the bomb. Without warning, the bomb detonated. The blast sent shrapnel into his body and knocked him over. It also blinded him in one eye, broke his forearm and took one of his hands.

That’s where the Alfred Mann Foundation, Steve Doctrow and Rogers and Cowan thought that they might be able to help improve the quality of Sides’ life. Founded by Alfred Mann in 1985, the foundation has several core goals including the exploration of how bionics can improve quality of life for people like James Sides. Rogers and Cowan helped to facilitate this exchange and promote the project. This kind opf breakthrough is unprecedented, and the Foundation wanted big attention for their unveiling.

They fitted Sides with a device that has two components. The first is smaller than a penny. It’s a tiny sensor that must be embedded within the muscles of the arm. This transceiver uses radio frequencies to interpret muscle movements that would dictate how the hand might respond. Outsides see a man moving his hand, but the science behind this shows an incredible understanding of the human body.

Although this technology is promising, Sides is one of only seven people in the world to have a robotic arm. The Alfred Mann Foundation hopes that these early proofs of concept will give way to more affordable devices that can be deployed to the general population.

What You Need to Know About Troubleshooting Wi-Fi Issues

Trying to figure out what is wrong with a network can be a difficult task. You need patience if you want to resolve the issue.

The problem can be either simple or a complex one depending on the situation and there are steps that you take in either case.

Apart from the complex issues that might be reason why your device cannot access the Wi-Fi network, there are two simple ones: your laptop or your router.

Probably the first thing that you should do is test the network by using another laptop or any other device that uses Wi-Fi. If this device can use Wi-Fi flawlessly, then the problem is with your computer instead and not the network.

Now that you know that the problem is with your system, ensure that the Wi-Fi switch is turned on your system. Usually there’s a hardware switch that you can flip off and on.

Windows will usually tell you whether it’s turned back on or not. However, if that doesn’t fix the problem, then you can try to reboot the system in order to see if that works or not.

Also, make sure you are connecting to the right network and using the right password if that didn’t work either. For that, click the Wi-Fi icon in the notification area for the networks in your area. It should say ‘Connected’ but it probably won’t.

Another thing that you can try is to shut down your firewall. Also, try checking for the number of bars right next to your network’s name to see if you have a strong connection or not.

If none of these work then there’s a problem with the network. Try rebooting it. Unplug the modem and router, wait for a couple of minutes and start it again.

Finally, if that doesn’t work, connect the laptop to the router through the Ethernet cable. This should tell you whether the issue with the router’s Wi-Fi. If that’s the problem, the go to the router’s settings and change the Wi-Fi channel.

Advantages to Synthetic DNA Molecules

Written by: The Midland Certified Reagent Company

Summary: Working with the human genome has enormous potential for the future.

Along with the ability to decode the human gene pool is the process to create synthetic segments of DNA. Synthetic oligos are perfect for testing because they simulate human DNA and can give scientists accurate results to demonstrate how a potential vaccine might affect the body. The ability to work with our gene pool will greatly enhance the understanding of medical science in the future.

Synthesizing a Reaction

The first step in creating a cure is isolating the genes involved in the disease, and how they affect the body. Once we understand more about the disease itself, we can work on testing drugs that will cause a certain reaction. For instance, if we wanted to cure cancer we might want to attack the gene that causes cancer cells to endlessly reproduce. We would need to identify the cancer gene responsible, and then see how to safely destroy or deactivate that gene without interfering with others.

This would be too difficult to test in living subjects, mostly because conditions are hard to duplicate. It’s now possible to perform DNA synthesis under precise lab conditions, which completely removes the need for a live subject until a cure has been defined and substantially tested.

Future Prospects

Soon, it may be possible for scientists to utilize RNA synthesis for their own aims. One method already tested involves using RNA to write code to DNA and turn molecules into storage devices. Maybe someday we’ll be able to write entirely new genetic code to existing DNA.

IT Training Is More Important than Ever

Written by Brand College

It’s no secret that the last seven years or so have not been great for our economy. Many people are still worried that we’re not actually out of it yet and that the next handful could be just as bad. Whatever the case, you still need a job. Hopefully, the recession has also made it clear that you need a job which will actually deliver a sufficient paycheck and that this means one you can depend on for the foreseeable future. Whether you don’t have a degree or the one you currently have isn’t working, consider getting into information technology training in Los Angeles.

There are countless ways you could do this. Right now, for example, Cisco training in Los Angeles is very popular. Learning about information services, software design and server management are all great options too.

The point is that you want your paycheck to be tied to the digital world. It clearly isn’t going anywhere any time soon. If anything, it’s getting more and more important. With the right training, you could land a job practically anywhere in the world.

For that, consider Brand College. It’s located at 529 Hahn Ave. Suite 101, Glendale, CA 91203-1052, so just a stone’s throw from LA. They have a history that shows they understand this important field and know how to pass it on to others too.

Are you hoping to take a plus training Los Angeles? If so, you can do much better than entrusting Brand College with your needs. Their reputation and staff speak for themselves.

Discovering New Cures for Age Old Diseases

Cancer has been a problem humans have been dealing with for ages, and it’s a continual thorn in our collective side. It’s a disease with a high mortality rate, and we understand a lot about what it does but not how to stop that process. While medical science works hard on cracking that puzzle, we’ve made progress on other diseases that have been problems for ages.

Understanding Disease

HPLC purification is a crucial process in forensic science, telling us more about how a disease has affected someone on a molecular level. We can use this process to test reactions of potentially harmful toxins, in order to isolate exactly how a disease affects the body. Once the reaction is observed, and repeated, it becomes something scientists can test for.

Understanding what a disease does is the first step in curing, killing or deactivating it.

How Cures Work

Going deeper, we can even use these synthetic strands to test for the presence of something. Phosphorothioate oligonucleotides, for instance, are “anti-sense” particles used in genetic therapy. These drugs basically deactivate whatever strand of DNA would otherwise cause the harmful genetic disorder to crop up.

We can also test for these chemicals and toxins in real-time, which means a diagnosis is much faster than it was even ten or twenty years ago. That’s made a significant difference in response times and diagnoses for patients in places like Africa, a region beset with malaria outbreaks. Testing has sped up results and that means doctors have more time to prescribe life saving medication to patients. The costs are also lower, so testing is feasible in poorer nations.

Are Medical Device Coatings Safe for the Body?

Written by: Denton Vacuum, LLC

Summary: Are medical device coatings actually safe for the body?

As medical science evolves, the need to put objects into a patient’s body increases. There are more gadgets that do more to keep patients alive and comfortable for longer periods of time. Consider just how much tubes like the catheter have changed. They are still not a pleasant experience, but aqueous coatings have made them easier to slip in and out of the patient’s body.

These chemicals bring up important questions about the safety risks posed to your body. Are these device coatings actually making patients safer?

Consider the Device

There are several kinds of anti-reflective coating possible for eye glasses. Each is good for a specific kind of user. Index-matching, for instance, functions like tarnishing a lens. So it is with coatings, each coating being suited to a specific purpose and carrying out a specific duty. Anti-microbial coatings, for instance, are designed to fend off bacterial infections that can seep through open wounds created by tubes into the skin.

Without these devices, patients still need a catheter or eye glasses, but their site or comfort levels may be diminished. In some cases, their health is jeopardized as they are at risk for infection.

Alterations to the Device

If the coating inhibits the device from doing its job, the coating is ineffective. That’s why medical manufacturers utilize a thermal evaporation system when applying coatings to a device. The finish is thin-film, often only micrometers in thickness, which presents almost no difference to the patient.

Thin film is a little different from the effect yo get with UHV sputter deposition. This process acts more like a spray can, and can give a smooth surface but it more often used to metalize something. You might find metalized plastic in joint replacements or acting as anti-static shielding for medical equipment in the patient’s room.

Improving Productivity In The Workplace Through Software

Written by Allied Time

Technology when used at work, contributes to boosting the efficiency of organizations and allow their employees to remain focused on value adding activities. Several productivity software target businesses particularly and provide these organizations with the adequate tool to perform their day-to-day tasks effectively. Through the automation of certain processes, communication is also enhanced.

Virtual Team Connections

Teams now perform well even at a distance. This is because they are connected via web portals, apps and software. These allow teams to share feedbacks and projects across different functions and branches. The quick sharing and access of information facilitates problem-solving and team working. People are able to show collaboration and partake their experiences and knowledge while being comfortably seated at their desks, and sometimes without even having to speak through the phone. All this is achieved through remote desktop sharing and email software.

Open and Communicative Environment

Software that are specifically designed to be used in the workplace aim mainly to break communication barriers. Even though email is a powerful tool, they tend to be more private and rarely constitute of a sharing tool. Collaborative tools are more appropriate for knowledge-sharing across multiple cross-functional teams, departments and branches.

Motivate Employees

Online time clock systems are used to monitor the attendance and working hours of employees. This data serves in the construction of effective reward systems. Some fingerprint time clocks allow people to consult their data online. This would help employees in knowing how they could improve performance and attendance rates.

Allied Time has operated since 1967. The company’s main line of products include employee time clocks and biometric systems.

Newly-restored version of “The Wizard of Oz” hits theaters, shelves

For most people, a slide and negative scanner can be used to preserve family memories. But in Hollywood, they are using tools more advanced than the average 35mm slide scanners to save memories of a different kind: film classics.

In late September, a newly-restored version of “The Wizard of Oz” debuted on DVD on Blu-Ray. In addition, movie theaters around the country screened the new version of the 1939 family classic to packed houses. The new version was done to commemorate the film’s 70th anniversary.

According to the Los Angeles Times, restoration work involved a pin-registered digital film scanner scanning three separate film negatives at 8k, a much higher resolution than was previously possible.

“In finding the 1939 nitrate Technicolor print, we got a different look for the film than we previously had,” says Ned Price, vice president of mastering at Warner Bros. Technicolor Operations. “The information allowed us to get not only finer picture detail but much better grain capture.”
