Nanomaterials Characterization

Alfa Chemistry offers a wide range of analytical techniques for material evaluation, process monitoring and failure analysis. For example, the scale of the structures observed in material characterization ranges from angstroms, in the imaging of individual atoms and chemical bonds, for example, up to centimeters, in the imaging of coarse grain structures in metals and so on. Characterization is a fundamental process in the field of materials science, without which no scientific understanding of engineering materials could be ascertained. Thorough mechanical, physical and chemical material testing, it is essential to the innovative product development. Scientists specialized in polymer, metal semiconductor, glass, ceramic, organic and inorganic oil and gas, etc, will be at your service for your testing and research needs. Advanced Load Fatigue & Durability Testing, Shock and Vibration Testing, Tensile & Mechanical Property Testing, Temperature & Humidity Testing, Metallurgical Analysis Testing, Microhardness, Melt Flow, Glass Content, Metrology Testing have all been provided by Alfa Chemistry . Alfa Chemistry is here to help optimize your product's lifecycle performance, take advantage of cost savings materials, increase productivity, develop new technologies and explore new materials.

Advanced Material Characterization

Material characterization is an integral part for developing suitable advanced material applications. With the development of science and technology, material characterization techniques have evolved and facilitated the understanding of matter's structure-property relationships1. At Alfa Chemistry , different characterization tools and techniques are now available to assess structural and functional properties of advanced material. While the characterization is a major field for material scientists, it remains an important aspect for all engineering areas and sciences. Testing service categories we provide mainly include, but not limited to, the following: Nanoparticles, Alloys, Metals, Metallurgical Analysis, Coatings and Thin Films, on Materials, Ceramics, etc.

Nanomaterials Analysis

Nanomaterials, in principle, are materials that have at least one dimension in nanometer size range. Nanomaterials are of great scientific interest as they are, in effect, a bridge between bulk materials and atomic or molecular structures. Bulk materials usually maintain constant physical properties regardless of size; however, size-dependent properties are often observed at the nanoscale. Thus, the properties of materials change as their sizes approach the nanoscale and the surface area to volume ratio becomes significant. Alfa Chemistry provides nanomaterials analysis including morphology analysis, surface analysis, size analysis, structural analysis, as well as component analysis using different analytical instruments.

Techniques:

1. Alfa Chemistry will gather the composition, physical, and chemical properties information of nanomaterials by providing all kinds of spectral analysis results, such as：

• Flame and Electro-Atom Absorption Spectroscopy (AAS)

• Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-OES)

• Inductively Coupled Plasma Mass Spectrometry (ICP-MS)

• Time-of-Flight Secondary Ion Mass Spectrometry (TOF-SIMS)

• X-Ray Fluorescence Spectroscopy/ X-Ray Photoelectron Spectroscopy/X-Ray Diffraction Spectrometry (XFS/XPS/XRD)

• Auger Electron Spectroscopy (AES)

2. Particle size analysis: The size and shape of the nanomaterials play decisive roles in their performance, so it is important to know the size of nanomaterials or even modify them into the size you desire when necessary.

 Microscopy
