Understanding the Benefits that PVD Coating Brings to Laboratories

October 14, 2016 by · Leave a Comment 

PVD coating is a preferred deposition method that is continuously expanding.

PVD-Coating-toolsWhen it comes to vacuum deposition systems, PVD technology has been consistently paving the way forward with its stop-gap solution to coating discrepancies. Now, PVD coating, or physical vapor deposition coating, does its magic within a vacuum vessel. Below is a brief description of how the PVD coating process works.

Breaking Down PVD Coating

The process of PVD coating starts with the product placement. The material that is about to be coated is placed on a fixture and then inserted into the vacuum chamber. Now, depending on the specific model of the PVD coating equipment being used, there are numerous ways where this can go, but the most common is as follows:

The unit is then set at a specific vacuum pressure that is desired by the user. Once it has been pumped down appropriately, the product will then be sputter cleaned and preheated. However, this does depend on the substrate and the type of process that the user is going with. Once the sputter cleaning has completed, there will be a negative charge applied to the cathode material.

The material that is being deposited will move to the substrate at an extremely high energy level and will then travel along the substrate’s surface until it reaches a specific placement site. Now, the bombarding of ions that occur amongst the substrate at the material will sputter the depositing material so there will be no build-ups that can often occur with electroplated coatings. This plays a large role in the quality of the finished result.

PVD Coating vs. Gold Plating

May 23, 2016 by · Leave a Comment 

Both techniques have their own unique advantages to them that offer the user numerous benefits.

gold-barsIn the jewelry business, there are several different processes and techniques used to achieve a gold look. Now, aside from the fake products, two of the more common ways to achieve this appearance are through gold PVD coating and gold plating. Sure, they sound like they’re essentially the same process, but each has their own unique advantages that adapt to certain situations. So, what differentiates the two from each other?

PVD Coating

Physical vapor deposition, otherwise known as PVD, is a process that occurs within vacuum deposition systems that produce a decorative and functionally beautiful finish. PVD typically utilizes titanium nitride to provide a tough, durable coating layer on top of a substrate. PVD coatings tend to be more resistant to corrosion, moisture, and the other wear and tear features that watch users undergo.

Gold Plating

Gold plating, on the other hand, occurs when a piece of real gold is plated onto another type of metal – say, stainless steel for example. This process is often done as a cost-efficient way to achieve the look of real good. One advantage that gold plating has is that it gives the product the look of actual gold. It’s aesthetically pleasing to the eye and can be used on a variety of products. And, without having to pay thousands more to obtain a thin film vacuum coating, you can save a substantial amount of money. However, gold plating doesn’t have the same durability and resistance that PVD coating offers, leaving its security at the whim of the user.

Vacuum Metalizing Everyday Household Items

February 20, 2016 by · Leave a Comment 

The trophies and medals hanging from your walls have that distinct shine thanks to PVD coating.

The process of vacuum metallization is essentially a form of physical vapor deposition. The process requires the combination of both non-metals and metals to evaporate and then deposit into a thin film. The most common metal used in vacuum metallization is aluminum because of its’ thermodynamic and reflective properties.


Vacuum metalizing gives off a highly reflective surface that’s similar to chrome. Also, when using aluminum, its low cost enables there to be an increase in production. This process also can be tinted for various colors such as: brass, copper, gold, blue, green, and black chrome.

Vacuum Metallization in Plastic Parts

Visually, if you were to coat a piece of plastic with metal, you wouldn’t expect there to be an increase in both gloss and reflectivity.

Through vacuum metallization, metallic properties such as abrasion resistance and electrical conductivity can also be added to plastic components. Upon completion of metallization, these now-metalized components are treated in the same light as metal plated parts. Although they carry the properties of metals, they tend to be lower in weight and have a high corrosion resistance as well. In addition, the electrical conductivity that now encompasses the plastic part can be controlled to avoid electrical surges.

Physical vapor deposition coating, or PVD coating, can be found in a variety of household items that are commonly found. Products such as: lamp reflectors, emblems, trophies, fishing lures, and advertising display items are only some of the products that are vacuum metalized. The immense amount of gloss and shine are what makes this method stand out.

Meet the Ancient World’s Greatest Inventor: Hero of Alexandria

February 2, 2016 by · Leave a Comment 

By Samuel Phineas Upham

Hero of Alexandria described the concept of steam powered engine, and was able to reproduce it, long before it was ever utilized in a factory setting. He was representative of a larger, Hellenestic movement toward an understanding of science and reason. He is widely considered to be one of the greatest inventors in the history of civilization.

To understand Hero, one must first understand that the period in which he lived was a transition. Greek ideals for mathematics, such as the work of Pythogoras, formed the basis for Hellenistic research but they were considered outdated ideals in many cases. The important concepts, such as empirical and deliberate experimentation, were kept and modified accordingly.

Hero likely taught in the Musaeum, which was created by Ptolomy, and was known to be an engineer. He taught physics and pneumatics, but these fields were not necessarily formalized. It’s likely he taught a variety of concepts in addition to these core concepts.

Hero created an aeolipile, which was similar to a rocket engine. Jets of steam exited a turbine, fueled by water boiling in a pan below, to create motion. He is also credited with the concept of the world’s first vending machine. One inserted a coin, which rested on a platform. The weight of the coin was counterbalanced, and holy water was dispensed for payment. Once the allotment was reached, the counter balance would cause the coin to drop into a pan and reset the valve. Hero’s quests for automation did not stop at snacks. He created a wind-powered organ, and a fountain that operated on self-contained hydrostatic energy.

Alternate Peptide Labeling Methods

January 19, 2016 by · Leave a Comment 

Read below to find out how protein labels can be altered for use in peptides.

To determine and investigate important biological interactions such as protein structures and enzyme activities, a fluorescent label is utilized on a peptide to provide powerful tools for researchers.

The Process

To label a peptide or a molecular beacon probe, a modification is applied to an isolated peptide. An alternate approach to this is to incorporate the label during the synthesis process. Some common strategies used to “dye” the peptides include: labeling the peptide during the synthesis phase, covalently modifying the synthetic peptides following synthesis, and taking advantage of the capabilities of thiolreactive protein labels.

Peptide labeling can also be achieved through a biotinylated amino acid as well. This is an indirect method however but still allows for the specific binding of the conjugates to the site. Peptides gain the advantage of being able to accept protein labels and not just specifically designed labels meant for peptides. Protein labels are highly based on an aqueous solution of a target protein. Although specific modifications have to be made prior to the labeling possible, it is ultimately achievable and has proven to be a useful alternative.

Summing it up

These fluorescent dyes give researchers a chance to take an in-depth look into peptides and their structures. With numerous methods being introduced into labeling procedures, there can be more modifications and changes made that will affect the amount of information that can be taken out of these labels. The flexibility of peptides allows researchers to use alternate methods to label peptides while maintaining a high rate of quality.

This Advanced Prosthetic is Already Changing Lives

December 3, 2015 by · Leave a Comment 

A retired staff sergeant is the recipient of a special gift from the Alfred Mann Foundation.

In the future, medical technology will push the boundaries between machine and human. We can already ingest tiny computers that provide us with data about our bodies, but soon we’ll work together with computers and machinery in a way that has only previously been hinted at in science fiction.

That’s where Staff Sergeant James Sides comes in. Sides is now retired, but he suffered a debilitating injury during a patrol. He came across an IED, and, while attempting to diffuse it, suffered severe damage to his arm and blindness in one eye when the device detonated within close proximity. His right hand was completely missing, “shredded to the wrist” in his words, and his forearm was broken.

The Army managed to fix the immediate damage and helped him to recover, but the missing hand made it difficult for Sides to accomplish even basic tasks that you might take for granted. For Sides, activities like opening a soda can or pouring and drinking a glass of water suddenly became time-consuming tasks. The feeling wasn’t pleasant.

The Alfred Mann Foundation, which was founded in 1985 with the goal of providing solutions to these challenges, located Sides and decided to do something about his situation. They embedded an electronic device in his arm. The device reads the movements in his muscles and outputs that data into a language the prosthetic he wears can understand. Using these techniques, Sides has 3 ranges of motion and can open and close his hand or move individual fingers.

Although there are only seven of these devices in circulation, the Alfred Mann Foundation hopes that working with Steve Doctrow and the team of Rogers & Cowan will help bring these devices the attention they deserve. These important devices will help so many reclaim the normalcy that injuries can cause.

What You Get When You Invest in an Employee Time Clock

October 17, 2015 by · Leave a Comment 

By Allied Time

The next time you have some money in your budget to spend on improving your company, you’ll want to look into a timeclock for your organization. If you’re a bit underwhelmed by the idea, it’s not surprising. When it comes to getting more from you employees, there are countless options. People pay huge sums to have gurus come in and talk to their people. Others may actually physically alter their facilities—something that isn’t inexpensive either.AlliedTime3

So when you hear that buying timeclocks will produce serious results, it makes sense that you’d scoff at the idea.

However, the evidence is there. When people aren’t given parameters about what’s expected from them, it becomes too easy for even the hardest working and most honest of employees to start slipping. Even worse, when these employees are keeping themselves disciplined, they’ll often find that some of their coworkers aren’t. This is how discontent grows amongst your ranks.

Introduce clocks to monitor your staff and everyone wins. You’ll soon find that people are getting more done and feel happier during their work hours. There’s just no way you’ll find a more affordable way to get these kinds of results from your people. Plus, once you’ve made the investment, these results are yours forever.

At Allied Time, the bottom line is making more of your company’s most valuable asset. With employee time clocks, you can make sure that every dime you spend on your staff is well worth it.

Grace Hopper and the Origin of “Debugging”

October 2, 2015 by · Leave a Comment 

By Phineas Upham

Any IT technician who debugs some code can thank Grace Brewster Murray Hopper for coining the term. She was a high-level computer programmer for the Navy throughout the World War II era of American military history, and she was one of the earliest advocates of machine learning.

Grace began her interest in computers at an early age. She had a deep curiosity about the inner workings of an alarm clock. Before her mother realized why all the alarm clocks in the house were “broken”, Grace had dismantled seven to figure out how they worked inside.

She attended Vassar, after some difficulty in the application process, but took a hiatus to join the United States Naval Reserve. Weighing in at 105 pounds, Hopper needed an exemption because she was below the Navy’s minimum weight standard. She trained at the Naval Reserve Midshipman’s School, and graduated in 1944. She served in the Mark I Computer programming division, which functioned something like an analytical engine for predictions. It was to be used to assist the Allied war effort towards the end of World War II.

Hopper was one of the first people who wrote a compiler for a computer. By 1952, the compiler was operational, and her colleagues were astounded. Prior to that moment, PCs were used as little more than glorified calculators.

Hopper also popularized the idea that computer programming should be written in a language that was easy to understand, rather than a machine language. Her ideas helped create the foundation for COBOL, which was one of the earliest high-level programming languages in computing history.

If you’re curious about the “de-bug” term, it involved a literal de-bugging. Hopper pulled a living moth from a computer at one point, as it had been interfering with the delicate circuitry inside.

How FinTech can Overcome Challenges and Surge Towards the Future

September 17, 2015 by · Leave a Comment 

The biggest opponent that fintech faces is a combination of itself and the regulatory environments that the technology finds itself in. Fintech shows a lot of promise in terms of solving some of the problems that are created by an underbanked population. Financial technology investments are also soaring, indicating that a revolution is imminent. For fintech to finally take off and become something more than digital wallets, a few changes need to be made.


One of the key aspects to fintech in the coming years will be trust, and not in the “build a warm relationship with customers” sort of way. Brand recognition will likely play a role in the future, but fintech will need to overcome challenges related to security that modern banks don’t contend with. For instance, the disappearance of bitcoins from Mt. Gox puts a major hole in the silver lining for bitcoin and cryptocurrencies. Renewing that trust will be crucial for fintech startups moving forward.

Big Data

Big data has become more than just a buzzword because it powers nearly everything we do. Big data can tell companies about customer behaviors and  provide insight into buying habits. It can also crowdsource certain decisions, or provide a crowdsources index similar to the volatility index. The range of applications for big data are nearly limitless.


Perhaps the largest area ripe for disruption is regulation. Often times, well-meaning regulation can end up crippling banks and startups trying to provide a basic service. There is no quick fix, except to vote for representatives who do not engage in knee-jerk politicking. Yet even the best of intentions can have unintended consequences.
