Lab Created Diamond Computer Chips

2010-07-04T20:17:00.000-07:00

Silicon chips have reached the limit of their capacity to act as a semi-conductor of electricity. "Silicon Chips" according to MIT Professor of material science, Dr. Wuensch states" Will melt into a puddle" at this rate and diamond is the solution to that problem. A modern computer system in the office will generate heat at [100] degrees celsius, enough to heat a small office on a cold day.

This has prompted scientist to discover a replacement material that can handle more electricity with greater conductivity without over heating. This quest set off a world-wide race to take control of the computer and synthetic diamond industry.

The initial players in this quest are De Beers who controls the most productive and valuable diamond mines on earth located in Botswana S. Africa. And Apollo Diamond who produce synthetic laboratory created diamonds in United States.

Apollo is owned by a first rate scientist whose dream was to create a better computer power chip..He knew that the ultimate conductor is the diamond itself. Diamond can conduct more electricity without over heating than any material on earth.. He also knew that even the world's best De Beer mine diamonds do not have consistent properties that you can depend on to make computer chips.

Synthetic laboratory created diamonds held the key. A new technology was created called "Chemical Vapor Deposition." This Apollo advanced [CVD] application grew diamond crystals of highest purity without metallic inclusions. These new "Hybrid Synthetic" lab created diamonds were uncovered and reported to De Beers "Diamond Trading Company."

This set off a series of events that compelled the De Beers group to start scientific research of their own. It was a two-fold attack on the [CVD] chemical vapor deposition industry. One was to develop diamond scanning equipment to detect a synthetic diamond entering the market place.

De Beers being most resourceful did just that. He launched a "Gem Defensive Program" and developed two state of the art diamond testing machines called, "Diamond Sure and Diamond View."

Events are unfolding and America's largest diamond testing facility, the "Gemological Institute of America has become aware of the Apollo Diamond as a possible threat to the entire natural diamond industry. We should take pause at the magnitude of the economic power sectors at play. We are talking about "Multi-Billion" dollars industries that effect change on a global level.

The [GIA] used their lab diamond testing "Spectroscope," which was state of the art at the time. The began testing the new synthetic stones, one by one. And after each test they discovered the Apollo synthetic lab created diamonds had no visible color spectra or absorption. It passed the natural diamond test! But testing was not over yet. The DeBeers "Gem Defense Program" had applied and was given permission by the [GIA] to also test the new synthetic diamonds with their next generation of "Diamond View and Diamond Sure" testing equipment.

These instruments use a new diamond testing technology called "Fourier-Transform Infrared Spectroscopy" [FTIR]. A system that can detect hydrogen related centers that have never be observed in natural diamonds. De Beers did detect [6200-6400] centimeter of hydrogen which is used to make Apollo synthetic lab created diamonds. De Beers was successful at detecting synthetic lab created diamonds. The diamond industry felt relief that the market price would remain stable.

But this was a meaningless exercise. Apollo was only interested in selling gem quality diamonds to fund his diamond computer chip program. His goal from the beginning was to create a " Better Computer Chip." They spent a decade trying to find the "Sweet Spot" where he can duplicate his scientific chemical vapor deposition experiment and reproduce an exact synthetic lab created diamond. After countless years of trial and error, Apollo Diamond pain stakingly persevered and finally found the "Sweet Spot" and was awarded a patent for his efforts.

De Beers was also a very creative and industrious individual. Being a man of action and with inexhaustible wealth, set out to develop his own synthetic diamond. He also new the diamond testing machines were only his first plan of attack. His second was in motion. He purchased his own "World Class" laboratory to create synthetic diamonds for computer chips. His facility was named " Element Six."

De Beers a privately held company called "Diamond Trading Company" has a very large agenda. He currently owns the largest single stock pile of high end diamonds on earth. He has accumulated this treasure over his [100] year mining history in Africa. His power allows him to manipulate world price on high end diamonds through Antwerp Belgium. His next goal is to create the first "Diamond Computer Chip" and control the world market and computer industry. If ever a man exist who could do this it would be DeBeers.

The rest of the world is now waking up to the colossal economic stakes. Now Europe and Japan have begun scientific endeavor toward the quest of creating the first synthetic lab created diamond computer chip. But Intel, the largest silicon chip producer in the United States is apparently indifferent to it all. The comment by Soumyanath, Intel's director of communication circuits research,"It takes about ten years to evaluate a new material, we have a lot invested in silicon and we're not about to abandon that." Unless Intel has revised it's position, the torch is in the hands of Apollo Diamond and DeBeers Element Six synthetic laboratories.

Apollo wasn't asleep at the wheel while all of this was going on. He continued his research after being granted a patent. His next scientific break-through was in collaboraton with French and Israel scientist. They together discovered how to produce a [CVD] snythetic lab created diamond with a positive and negative charge.

The process was called "Boron-Doped N Type." Apollo injected boron mineral with a [P-N] positive and negative charge, into the diamond crystal lattice. Resulting in the first diamond on earth with the capacity to hold a charge and conduct electricity without over heating. The race is on.

Diamond Grading Equipment

2010-07-04T20:08:00.000-07:00

Are you looking forward to buy quality proven diamond grading equipment?

Everyone is not experienced enough to determine the authenticity of precious stones like diamond, on the basis of the four Cs i.e. color, clarity, cut and carat. So, it is better to buy professional diamond grading equipment to make sure your stones are genuine.

Types of Diamond Grading Equipment

Here are the main types of diamond grading equipment:

Loupe: This magnification device can be used to determine features such as diamond clarity, dimensions, and inclusions. These are available as simple lens or with multiple lenses. Loupes availability in triplet or quadruplet lens system helps provide better focus and enhanced clarity..

Diamond Moissanite Testers:

: To test the authenticity of your diamond, combine a moissanite tester with your traditional diamond tester. A diamond moissanite tester helps distinguish original diamonds from synthetic moissanites, which largely go unnoticed by traditional diamond testers.

Lamp:

This convenient fluorescent lamp comes with a magnifier, tray, nipper and a box. This easy-to-use, portable light source with no predominant yellow or blue tint helps determine the diamond quality.

Electronic Diamond Testers:

These testers use thermal conductivity to test diamonds. Different available models include direct AC current tester and testers with rechargeable batteries. Testers display test results through beeps and lights, making it the best testing aid for even a layperson.

Diamond Gauge:

This equipment helps in determining the precise measurement of loose and mounted diamonds. This includes stone's cut quality, dimensions and carat weight.
Before grading, the surface of diamonds must be cleaned with a special cloth. You can also boil them in acid or wash them with alcohol. Avoid storing diamonds in anything that is not meant for the purpose. You can buy a specially crafted paper packet ideal for storing diamonds.

Assessing a Diamond Grading Certificate

A diamond grading certificate describes the technical details of a diamond, verifying its quality and identity. However, a diamond grading certificate is provided only for loose diamonds. To assess the certificate, follow these steps:

o Look for the name of the organization that issued it, for example, Gemological Institute of America (GIA) and European Gemological Laboratory (EGL).
o Date of issuance of the certificate
o Check the cut, carat weight, measurement and color
o Check the proportions section.
o Check polish and symmetry
o Check for fluorescence

Diamond Testing Equipment

2010-07-01T14:54:00.000-07:00

Are you having a hard time distinguishing real diamonds from fake stones? No need to worry, as there is a wide range of diamond testing equipment available in the market. These equipments help in verifying the authenticity of diamonds, without one having to acquire any gemological education or experience. This makes diamond testing possible for practically everyone!

Need for a Diamond Testing Equipment

In today's competitive gemstone market, all professional jewelers must own a sophisticated range of diamond testing equipment. This is because traditional testing equipments are not equipped to deal with the growing issues of today, which include the most important need of distinguishing real diamonds from simulants. Simulants are fake or cultured diamonds that are artificially prepared in a laboratory. These resemble real diamonds in several aspects, making it difficult for a traditional tester to distinguish it from a real one.

How Does Diamond Testing Equipment work?

Diamonds have the highest thermal conductivity among precious and semi-precious stones, after synthetic moissanites. A diamond tester comprising a fine-tipped probe helps to determine the level of thermal conductivity. Diamond testers help differentiate diamonds from other simulants, which include CZ (Cubic Zirconia), YAG (Yttrium Aluminum Garnet) and GGG (Gadolinium Gallium Garnet).

However, this thermal conductivity testing device has certain limitations, as it fails to detect thermal inertia in some rare diamonds. This includes the Type IIb diamonds, which are semiconductors and blue diamonds (containing boron), such as the famous Hope Diamond. This results in the device registering these natural diamonds as fake diamonds. Moreover, since diamonds and moissanites have similar thermal conductivity, the device registers moissanites as real diamonds. Hence, using a thermal conductivity device alone could yield inaccurate results.

Hence, it is advisable to use other testing equipment to supplement the thermal conductivity test. This could include tests that measure the optical properties or electrical conductivity of stones.

EGL Diamond Certification

EGL Diamond Certification is done by the European Gemological Laboratory.
The price of diamonds is very much dependent on having a proper certification of that diamond.
A Certification is an assurance of quality. A diamond certification is a detailed diamond quality report issued by an accredited independent gemological laboratory. The most recognized gemological laboratories that provide certified diamond quality reports to the diamond and jewelry industry are listed below.

G.I.A. - Gemological Institute Of America
A.G.S. - American Gem Society
E.G.L. - European Gemological Laboratory
I.G.I. - International Gemological Institute

Certifications verses appraisals: It is vital to understand that appraisals are not the same as certifications and often not as accurate as a certified diamond quality report performed by an independent gemological laboratory. Such a report is based on a mechanical and technical examination of the diamond using verified test and electronic equipment . Appraisals are done individually by an appraiser and are only as accurate as the skill, knowledge and training of the appraiser.

A Certified Diamond Reports should provide the following information:
Shape
Measurements
Weight
Depth Percentage
Table Percentage
Girdle Thickness
Culet Size
Polish
Symmetry
Clarity Grade
Color Grade
Fluorescence
Comments about Diamond
Plot of Internal and External Inclusions

With the EGL certification, the EGL also issues a condensed report on a diamond known as a consultation. The difference between the consultation and the certification is that it does not have depth percentage, table percentage, polish and symmetry or fluorescence grades. And only documents the carat weight, color grade, clarity grade and plotting diagram. This is a quick short analysis useful when purchasing bulk diamonds.

EGL Certified Diamonds wholesale at as much as 20% less than similar clarity & color AGS or GIA certified Diamonds. This seems to indicate the diamond industry's perception that the EGL certification does not quote equal the same standards of accuracy and reliability as say, the AGS or GIA certifications. This price variation can be utilized to find a diamond price below its actual quality but, for the most part, an owner of a diamond will recognize the true characteristics and quality of the diamond and price it accordingly.

Electrical Equipment For Testing

It is not possible to dream of an existence that is devoid of electrical gadgets. These are so intrinsically entwined with our everyday life that we cannot do without their help. These equipments are responsible for making our chores thousand times easier and faster. Electrical test equipments are one such indispensable product without which an ordinary human being's life is likely to become crippled.
Superior quality electrical equipment is usually one that has been made from high quality materials that make them long lasting and capable of taking heavy loads. They are apparently complicated but become easy to use through practice. They are easily available online these days in plenty of websites which offer great discounts and take care of supplies to companies placing orders.

Electrical test equipments can be typically categorized into several categories depending on which type of industry they cater their services to:
* Burn-in test equipments: this particular device is used for the purpose of electrical testing. These are used to examine boards and power chips and mostly used by those who make semi-conductors. Such gadgets are used with the help of voltages, temperatures and power cycling.

* Backplane: these are widely used for networking purposes and relatively more user-friendly as compared to the automatic ones. Resistors and capacitors are tested with the help of these instruments that are similar to printed circuit boards divided into multiple sockets to test different gadgets.

* Battery testers: these examine the performance of fuel cells, check voltage, charge, DC resistance and its temperature and indicate if it due for a change. They are primarily used to test the endurance power and performance quotient of any product.
* Automated test equipment: being the most sophisticated, it is used to measure and test some specific industrial units through computers. Thorough background knowledge about the installation and programming is necessary before one begins using these.
The greatest advantage in using these equipments is that it entails very less human effort and can be repeatedly used. Such automated tools are good for testing interconnections and circuit boards.

In an age dominated by electrical appliances, both in the home and office sector, these testing equipments have grown significantly in value. They are found in batteries, ammeters, locators, testers, gauges etc. At times, electrical appliances come with a label which shows tested along with a date. This means that a Portable Appliance testing device has checked its safety features.

This technology is important to guarantee that any equipment is operationally sound and it is safe for the people to use. This is vital to check if devices are safe to use particularly in case of those equipments which may have the potential to harm.

Medical Laboratory Equipment

Medical lab equipment may be the most expensive lab equipment to keep on hand. Laboratory rules and state laws strictly govern the handling, storage, and disposal of biological materials. Most scalpels, vials, and other tools for taking samples can only be used once, and must be properly disposed of after coming into contact with blood or other bodily fluids.

Equipment in a medical lab can be divided into two categories: one-use items, and larger machines. The one-use items are syringes, scalpels, vials, and anything else that cannot be used on more than one person, or even for more than one sample. While these items are functional after one use, they pose great risk of cross-contamination. This could result in tests giving a wrong result, or in the worst scenario, infecting another patient.

While most sterilization processes do kill upwards of 99 percent of micro-organisms, there is always a chance--however slim--that a re-used item could be contaminated. In the interest of malpractice costs and professional ethics, anything that touches a patient will usually be thrown out. Medical labs minimize waste from this practice by making parts interchangeable. For example, only a scalpel blade is tossed, while the handle is kept for a new blade.

The remainder of hospital lab equipment is larger machines that do not actually come into contact with body tissue or fluids. This includes centrifuges, spectrophotometers, and other devices necessary for the analysis of microbiological agents. Machines of this nature must be regularly cleaned and sterilized, but do not pose any risk of contaminating other samples with re-use.
