Never become so much of an expert that you stop gaining expertise.

Denise Waitley

TRI/Princeton has gained credibility by working for decades in several scientific disciplines. As a result it has established expertise in some basic sciences that are not only broadly applied but which address key elements of the Institute’s research programs. Using skills in surface science, material science, optical measurements and fluid flow; TRI has established capabilities ranging from the performance of disposable wipes to the mapping of human metabolic profiles using hair diagnostic techniques.

Our long period of success stems from our people. Scientific staff which performs innovation research, collaborates with technology partners and establishes connections between basic science and practical need.

Discover more about TRI’s Areas of Expertise by reviewing the current list of technical skills areas, applications and major research programs.

Since surface phenomena are fundamental to interactions between products, to perception and to performance in many applications, TRI has developed a strong set of tools to help the industry measure interfacial phenomena.

Surface Science

Characterization: SEM, Micro-fluorimetry, FTIR

Friction Measurements, Adsorption, Active Deposition

Coatings and Abrasion Testing

Fiber/Fiber Bond Strength

Materials Science

Measuring bulk, mechanical and structural properties of fibers, textiles, polymers, woven and non-woven materials is an integral part of TRI competencies. New method development and custom measures are an axis of research at the Institute which aims to serve the needs of industries that rely on these measures to better understand performance issues, root cause analysis, quality improvement or to drive innovation in their markets.

Ongoing research efforts in:

• Tensile Testing – Axial, Torsional
• Thermo-Mechanical
• Crystallographic (XRS)
• Porosity Characterization

Optical Measurement

A broad array of imaging solutions and custom method development enables TRI to support your research, whether you are using imaging to qualify appearance or to understand surface characteristics, there is a technique suited to your needs.

Cutting edge technologies are now available, such as optical coherence tomography which allows high-resolution 3-D imaging to a depth of hundreds of microns as well as reflectance, color and shine analysis. High res SEM and TEM complement the offering .

Ongoing Research Programs involving:

• Reflectance/Shine
• Appearance / Color Management
• Image Analysis
• Single Fiber Reflectance
• Microscopy: SEM, TEM, optical, micro-fluorimety
• OCT : 3D Optical Imaging

Fluid Flow in Porous Materials

The Center for Modeling and Characterization of Porous Materials deals primarily with the interaction of liquids in porous materials.  In particular, the scientists of TRI are currently focused on:

Pore Volume Distribution Measurement

Permeability Assessment

Absorbency Testing

Wicking And Capillarity

Absorbency/Swelling Profiles Measured

Control of transport across porous media is crucial to performance in many applications : whether you need to control flow of electrolytes, actives, pollutants or that of fluids, a precise measurement of porosity, pore volume distribution or permeability may be required. TRI has the know-how and the specialized equipment to allow you to get the data you need, efficiently.
