SEM Surface Analysis with Scanning Electron Microscopy  

Mesoporous silica (SBA-15 type) is widely used in catalysis and energy-related applications, where surface morphology and pore uniformity are essential. High-resolution SEM imaging provides nanoscale visualization of particle shape, pore arrangement, and surface roughness.

• Examine ordered mesoporous structures with ultra-high-resolution SEM
• Assess particle morphology for catalytic and adsorption efficiency
• Identify defects or irregularities in pore distribution

Electrospun nanofibers require precise control of surface structure and fiber uniformity to ensure performance in medical and filtration applications. SEM imaging highlights fiber diameter, alignment, and surface smoothness for quality assessment.

• Characterize nanofiber morphology at sub-micron scale
  
  
• Detect irregularities such as beads or non-uniform thickness
  
  
• Correlate fiber structure with application-specific properties

Steel components fabricated by additive manufacturing undergo microstructural changes under thermal stress. Automated in situ EBSD at elevated temperatures reveals grain growth, recrystallization, and texture evolution in real time.

• Monitor grain structure evolution during heating
• Capture recrystallization and phase transformation pathways
• Relate thermal behavior to mechanical reliability in service

Equal-channel angular pressing (ECAP) refines aluminum grain structure for enhanced strength. SEM and EBSD analysis demonstrate grain refinement, boundary misorientations, and defect evolution introduced by severe plastic deformation.

• Visualize ultrafine grain structures formed by ECAP
• Quantify misorientation distributions with EBSD
• Assess improvements in strength and ductility through microstructural control

Fatigue failure is one of the most common failure modes in metals. It begins with small cracks or defects that gradually grow until they form a major fracture. High-resolution SEM imaging of fractured Ti-6Al-4V surfaces reveals striations, microvoids, and fracture origins that explain how these cracks evolve.

• Examine nanoscale fracture features in titanium alloys
• Identify initiation points of fatigue cracks
• Link fracture morphology to and alloy performance

Complex geological samples often require both structural and compositional insight. TESCAN Essence™ EDS integrated within SEM imaging provides seamless mapping of mineral phases and trace element distributions.

• Combine SEM morphology with EDS chemical analysis
• Map elemental distributions across heterogeneous minerals
• Improve workflow efficiency with integrated SEM–EDS characterization

Separator integrity is vital for battery safety and performance. SEM surface analysis uncovers pore morphology in separator membranes.

• Visualize separator pore networks in high detail
• Detect surface or structural defects that affect performance
• Correlate microstructure with electrolyte uptake and safety

Powder morphology directly influences electrode packing density and electrochemical behavior. SEM imaging enables quantitative particle size analysis and surface defect detection in active battery materials.

• Measure particle size distribution with high accuracy
• Assess surface roughness and particle agglomeration
• Correlate powder morphology with electrochemical performance
