Superoleophobicity is a phenomenon where the contact angles of various oil droplets with
low surface tension on a solid surface are larger than 150°. In the past few years, there has …

In this Review, we survey recent developments in the emerging field of high-speed variable-
z-focus optical elements, which are driving important innovations in advanced imaging and …

Underwater superoleophobic surfaces have attracted increasing interest because of their
remarkable antioil ability and wide range of promising applications. In the meantime …

Liquid dielectrophoresis is a bulk force acting on dipoles within a dielectric liquid inside a
non-uniform electric field. When the driving electrodes are interdigitated, bulk liquid …

Developing tunable lenses, an expansion-based mechanism for dynamic focus adjustment
can provide a larger focal length tuning range than a contraction-based mechanism. Here …

The observed dependence of spin relaxation on the identity of the donor atom in n-type
silicon has remained without explanation for decades and poses a long-standing open …

Natural visual systems have inspired scientists and engineers to mimic their intriguing
features for the development of advanced photonic devices that can provide better solutions …

The increasing requirements of hyperspectral imaging optics, electro/photo-chromic
materials, negative refractive index metamaterial optics, and miniaturized optical …

We have fabricated a fully-flexible, focus-tunable microlens array on a sheet and
demonstrated its imaging capabilities. Each liquid lens of the array is individually tunable via …

Electric field-based smart wetting manipulation is one of the extensively used techniques in
modern surface science and engineering, especially in microfluidics and optofluidics …
