Negative resistance for colloids driven over two barriers in a microchannel

Video of superparamagnetic colloidal particles which are confined in a microchannel of 30µm width. The particles are driven into motion by tilting the microscope. Two...本数据集包含受限在宽度为30µm的微通道（microchannel）内的超顺磁胶体颗粒（superparamagnetic colloidal particles）的观测视频。这些颗粒借助倾斜显微镜实现运动驱动，两组……
