If scientists shine a single particle of light on a screen, the particle does something strange: It shows up in two places at once. 如果科学家将单个的光粒子投影在屏幕上,光粒子有奇怪的反应:它会同时在两个地方显像。 edu.163.com 2. To ask after the position of a single particle would be...
To evaluate quantitatively the influence exerted by the shape and structure of nonspherical, nonideal particles on the results of single-particle scattered-light size analysis, measurements were conducted with individual particles of different materials (glass, limestone, and quartz). For this purpose, ...
(2004) developed models based on population balances and heat and mass balances to describe the evolution of the particle morphologies obtained from spray drying. In the light that the precise experimental conditions used in spray dryers are often not accessible in single droplet drying devices (as...
6). Due to the sparsity of Env on individual particles9, we derived statistical power from single-particle averaging of hundreds of aligned individual HIV-1 assembly sites. Single assembly site averaging was used to determine the probability density of Env with respect to the elevation angle (φ...

Determination of and evidence for non-core-shell structure of particles containing black carbon using the Single-Particle Soot Photometer (SP2) The large uncertainty associated with black carbon (BC) direct forcing is due, in part, to the dependence of light absorption of BC-containing particles ...
A consequence of the quantum mechanical uncertainty principle is that one may not discuss the path or "trajectory" that a quantum particle takes, because any measurement of position irrevocably disturbs the momentum, and vice versa. Using weak measurements, however, it is possible to operationally ...
Electrocatalytic technologies play a vital role in the advancement of hydrogen energy and other renewable green energy sources, with nanocatalysts gaining significant attention due to their size-dependent electrocatalytic activity and broad applications. Single-particle electrochemistry offers a powerful app...
nm quantum dot-labeled flXPA on NDλ. Particle position (bottom) was localized using Gaussian fittings to the intensity profile on the fluorescence image (top). Dashed lines separate phases and diffusive modes are labeled according to particle displacement: paused (P, displacement <130 nm,...
