Field-driven gapless spin liquid in the spin-1 Kitaev honeycomb model

Physical Review Research, 2020
Recent proposals for spin-1 Kitaev materials, such as honeycomb Ni oxides with heavy elements of Bi and Sb, have shown that these compounds naturally give rise to antiferromagnetic (AFM) Kitaev couplings.

Nanopipette/Nanorod-Combined Quartz Tuning Fork–Atomic Force Microscope

Sensors, 2019
We introduce a nanopipette/quartz tuning fork (QTF)–atomic force microscope (AFM) for nanolithography and a nanorod/QTF–AFM for nanoscratching with in situ detection of shear dynamics during performance.

Characterisation of tissue factor-bearing extracellular vesicles with AFM: comparison of air-tapping-mode AFM and liquid Peak Force AFM

Journal of Extracellular Vesicles, 2013
Introduction: Extracellular vesicles (EVs) are shed from cells and carry markers of the parent cells. Vesicles derived from cancer cells reach the bloodstream and locally influence important physiological processes.

Single-particle chemical force microscopy to characterize virus surface chemistry

BioTechniques, 2020
Two important viral surface characteristics are the hydrophobicity and surface charge, which determine the viral colloidal behavior and mobility. Chemical force microscopy allows the detection of viral surface chemistry in liquid samples with small ...
