Laser Fabrication and Comparative Study of Planoconcave and Planoconvex Microlenses on Fused Silica and Sapphire

open access: yesMicromachines
We report on fabricating planoconcave lenses using a picosecond 355 nm wavelength laser and a CO2 laser. We also report the fabrication of the planoconvex microlens array on fused silica by patterned micromachining using a picosecond laser and reshaping ...

Micropatterned Surfaces with Unidirectional Wetting Properties for Liquid Transport

open access: yesSmall Structures, EarlyView.
Micropatterned surfaces that guide droplets in a single direction are gaining attention for their role in liquid transport. This review explores how surface designs enable such behavior, from gravity‐driven flow to stimulus‐responsive movement. It also discusses fabrication techniques, design challenges, and emerging strategies to advance directional ...

Thermometer Ions, Internal Energies, and In‐Source Fragmentation in Ambient Ionization

open access: yesMass Spectrometry Reviews, Volume 45, Issue 2, Page 260-281, March/April 2026.
ABSTRACT Ionization and fragmentation are at the core of mass spectrometry. But they are not necessarily separated in space, as in‐source fragmentation can also occur. Here, we survey the literature published since our 2005 review on the internal energy and fragmentation in electrospray ionization sources.

Influence of Micropillar Height Modulation on Droplet Evaporation and Wetting State Transitions

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 3, 3 February 2026.
Controlling droplet evaporation dynamics is crucial across many fields. Here, it demonstrates laser‐fabricated polymer micropillar arrays with tailored height variations to regulate evaporation behavior. While all arrays exhibit superhydrophobic wetting, their distinct height profiles effectively slow evaporation and alter evaporation modes ...

A Bidirectional Mode-Locked Fiber Laser for Asynchronous Noise-like Pulse Generation

open access: yesPhotonics
We demonstrate a bidirectional fiber laser with an artificial saturable absorber of a step-index multimode fiber sandwiched by single-mode fibers. Two asynchronous noise-like pulse sequences with a repetition frequency difference of 3.16 kHz are obtained.
