Join MA-tek
Nanomaterials possess characteristics such as high specific surface area, quantum size effects, and tunable composition/morphology, and have been widely applied in semiconductor films, optoelectronic devices, sensors, biomedical materials, catalysis, and energy storage technologies. However, the nanoscale structures themselves have features such as small particle size, complex interfaces, and high surface reactivity, making morphology, surface chemical state, doping distribution, and compositional uniformity key indicators that affect functionality and product performance.
MA-tek has cross-scale material analysis capabilities, allowing for layer-by-layer analysis from micron-scale structures to atomic-level compositions, and can reconstruct composite material structures using multimodal imaging (2D + 3D). In addition, we assist clients in establishing correlation models between material processing parameters and application performance, supporting formulation development, process optimization, and quality verification, accelerating the introduction of new materials into mass production.

Frequently Asked Questions
Q1. Why do nanomaterials easily exhibit particle agglomeration?
A. Nanoparticles have high surface energy, making them easily attracted to each other and agglomerate.
Q2. How to verify the surface modification effects of nanomaterials?
A. It is necessary to detect changes in surface chemical bonding and functional groups.
Q3. What effects can uneven doping concentration or element distribution cause?
A. It can lead to instability in electrical, optical, or catalytic performance.
Q4. How to confirm whether the structure of the multilayer stacking of nanocomposite materials is stable?
A. It is necessary to observe the continuity of the interface, lattice matching, and phase changes simultaneously.
