Irvine, Calif., Oct 24, 2013 – Nanovea demonstrates for the first time the ability to measure a continuous Stribeck Curve. Using the Nanovea Tribometer advanced speed control, from 2000 to 0.01 rpm, within 10 minutes software monitoring provides a complete Stribeck Curve. Prior to this advancement a Stribeck Curve has been shown to be evaluated in a stepwise fashion requiring data stitching.

The ability to accurately measure mechanical properties, using Nanoindentation, in the fields of Life Science has recently become an important aspect of many current studies. In some cases, understanding the mechanical properties of soft biological surfaces have helped uncover the mechanical effects of diseases. Understanding mechanical properties provides a context for identifying the local mechanical behavior linked to specific changes.

PRESS RELEASE

Feb 21, 2013 – Irvine, CA – Nanovea announced today the completion of a Nano Wear Testing System capable of speeds as high as 1400mm/sec. The unique length of stroke, up to 10mm, combined with a linear movement at a rate up to 70Hz, and possibly at higher frequencies, allows speeds never before available for Nano Wear Testing.

In profilometer studies where the interface of surface features, patterns, shapes etc., are being evaluated for orientation, it will be useful to quickly identify areas of interest over the entire profile of measurement. By segmenting a surface into significant areas the user can quickly evaluate boundaries, peaks, pits, areas, volumes and many others to understand their functional role in the entire surface profile under study.

Hydrogel is known for its super absorbency of water allowing for a close resemblance in flexibility as natural tissue. This close resemblance has made Hydrogel a common choice not only in biomaterials, but also electronics, environment and consumer good application such as contact lens. The use and diversity in application have each their own unique needs and requirements. One such requirement will be known and controlled mechanical properties using nanoindentation.

Traditional Puncture Tests are typically used to determine the penetration characteristics of a wide range of protective material such as films, foils or membrane. It is widely used in food and medical industries on applications ranging from food packaging to rubber gloves and needles. The test is preformed like that of a compressive test. A probe, with multiple tip selection, uses increasing load until material is penetrated and load is recorded at failure.

Some thoughts on what to consider when reviewing the two white light techniques: http://www.nanovea.com/News/Newsletter/Apr12.html

Oxidation resistance is critical for metal components in high temperature environments. Exposure to high temperatures can result in the depletion of the metal with rapid oxidation and material loss. Without protective coatings, surface oxidation adversely affects the performance and durability of the metal component. For example, engine parts, turbine blades, tooling and many others.

Irvine CA, January 18, 2012 - Nanovea today announced the arrival of the N3 line dedicated to providing high-end measurement technology to the broader market. Nanovea has fully automated their measurement techniques while designing to price in the $20K market.

The intention of shot peening is ultimately to alter the mechanical properties of a given surface. By hitting the surface with controlled shot the surface will deform plastically. Proper Instrumentation, nanoindentation, will play a vital factor in achieving reliable and intended results.

Microindentation hardness mapping has been widely used to assess the variation of mechanical properties across a large surface area. However, with the study of applications such as glass it is the crack initiation that is of particular interest. It is for this reason that acoustic emission can be used during the mapping of indents to not only map hardness but also map the crack initiation values over the surface area.

When lubrication is applied to reduce the wear/friction of moving surfaces an increasing load can shift the lubrication from several regimes such as Boundary, Mixed and Hydrodynamic Lubrication. The fluid viscosity, the load that is carried by the two surfaces and the speed that the two surfaces move relative to each other combine to determine the thickness of the fluid film. It is this process that determines the lubrication regime. How the regimes react to friction is shown in what is called a Stribeck curve.

FOR IMMEDIATE RELEASE

July 14, 2011 – Irvine, CA – Nanovea today introduced its patent pending breakthrough method of reliably acquiring yield strength through indentation; ultimately replacing the traditional tensile testing machine for yield strength measurement.

Creep can be characterized as the result of a solid material that is slowly and permanently deformed under the influence of stress. Deformation results from the consistent stress below the yield strength of the material. The amount of applied stress and its duration can eventually lead to the failure of the given material. Ultimately, it is for this reason that Nanoindentation creep measurement provides crucial information to study material behavior.

Paper surface topography is vital to the intended use and quality of the product. To control paper product quality it will heavily rely upon quantifiable, reproducible and reliable surface measurement. Precise surface measurement and evaluation of a paper product can lead to the best selection of processing and control measures. The Nanovea 3D Non-Contact Profilometer utilize chromatic confocal technology with unmatched capability to measure paper surfaces.

While R&D topics continue
to lead as a beacon for economic recovery, a crucial part of the R&D process
continues to receive little to no attention. And make no mistake, you are about
to learn of the single most important factor in the advancement of new or
improved material technologies around the world.
