The size is determined by a dynamic light scattering technique. This method measures fluctuations in the intensity of scattered light from a sample, which are directly related to the Brownian motion of the particles. Smaller particles move faster, causing more rapid fluctuations in the scattered light. This allows for the calculation of their diffusion coefficient and subsequently their size using the Stokes-Einstein equation.

Despite recent progress in preparing numerous types of nanosheets, it remains a difficult challenge to assemble the tiny building blocks into functional macroscale architectures suitable for practical applications. Here we introduce a diffusion driven layer-by-layer assembly process and demonstrate its

Multicapillary column ion-mobility spectrometry (MCC-IMS) may identify volatile components in exhaled gas. The authors therefore used MCC-IMS to evaluate exhaled gas in a rat model of sepsis, inflammation, and hemorrhagic shock. Male Sprague-Dawley rats were anesthetized and ventilated via tracheostomy

Mean particle diameter가 35 μm라고 specification sheet에 적혀있는데, 이 기준이 정확히 무엇인지 궁금합니다. 각 particle이 직경 35 μm인 구와 동일한 부피를 가진 것일까요? 아니면, 2D 평면에서의 단면적이 직경 35 μm인 원과 동일한 것일까요? 감사합니다.
