TL;DR: In this article, a Gaussian beam for excitation and a hollow Bessel beam for depletion (GB-STED) was used for super-resolution imaging of brain tissue.

TL;DR: A team of Chinese researchers led by Liangyi Chen and Kebin Shi has created a novel dual-mode high-speed SR microscopy technique capable of revealing previously unseen sub-cellular structures and dynamic processes, allowing both the cellular landscape and molecular identity in live cells to be observed in 3D over prolonged periods.

TL;DR: In this article, a deep imaging STED microscopy by using Gaussian beam for excitation and hollow Bessel beam for depletion (GB-STED) was proposed. And the proposed scheme showed the improved imaging depth up to ~155m in solid agarose sample, ~115m in PDMS and ~100m in phantom of gray matter in brain tissue with consistent super resolution, while the standard STED shown a significantly reduced lateral resolution at the same imaging depth.

TL;DR: In this paper, a room temperature ultraviolet surface-plasmon-polariton nanolaser at a wavelength of 360nm with a threshold as low as ∼ 0.2MW/cm2 was demonstrated, which provides a powerful evidence for potential application of the singlecrystalline Al film in plasmonic devices.

TL;DR: In this paper, a linear polarization synthesis based on optical heterodyne interference between two circularly polarized lights with opposite handedness was proposed to control the rotation of a trapped vaterite particle in water.
