Description générale

Monodisperse polystyrene based micro particles (size: 30 μm) are a particle size standard, ideal for characterizing particle size distribution (PSD) of test samples.

Application

Used to calibrate and validate the performance of particle size analyzers.
Monodisperse polystyrene latex particles can also be used to:
  • validate the Airy Disc First Fringe (ADFF) analysis technique based on size measurements
  • study the size effect of polystyrene microplastics on the sorption of organic contaminants

Caractéristiques et avantages

  • suitable for routine instrument calibration checks, testing and corrections
  • available in 5 mL pack size as a neat sample

Remarque sur l'analyse

For every lot exact values of particle size and standard deviation are determined with an accuracy of 0.001 μm. The size determination of these particles follows procedures described by National Institute of Standards and Technology (NIST, USA) respectively by the Community Bureau of Reference (BCR), esp.:
  • Transmission electron microscopy (TEM)
  • Scanning electron microscope
  • Light microscopy
  • Coulter™ counter with MDF-system
Calibration of equipment is carried out with NIST-respectively BCR-particle size standards.

Pattern separation is a process that minimizes overlap between patterns of neuronal activity representing similar experiences. Theoretical work suggests that the dentate gyrus (DG) performs this role for memory processing but a direct demonstration is lacking. One limitation is the

Manipulation of visual experience can considerably modify visual responses of visual cortical neurons even in adulthood in the mouse, although the modification is less profound than that observed during the critical period. Our previous studies demonstrated that low-frequency (2Hz) stimulation

The relationship between tickling, sensation, and laughter is complex. Tickling or its mere anticipation makes us laugh, but not when we self-tickle. We previously showed rat somatosensory cortex drives tickling-evoked vocalizations and now investigated self-tickle suppression and tickle anticipation. We

Various theories and their associated mechanisms have been proposed as the neural basis of phantom sound perception (tinnitus), including central gain enhancement and altered cortical oscillations. However, it remains unknown whether these cortical changes directly cause tinnitus, or simply coexist
