Femtolitre Volume cryoEM Sample Preparation Using a Force‐Sensitive Microfluidic Cantilever

open access: yesAdvanced Materials Technologies, EarlyView.
Cryogenic electron microscopy enables structural imaging of biological molecules, but current methods lack targeted extraction of subcellular content for direct vitrification. This study introduces a force‐sensitive microfluidic cantilever pipette that aspirates and dispenses femtolitre volumes from individual cells onto electron microscopy grids.

Holes in the walls: primordial black holes as a solution to the cosmological domain wall problem

open access: yes, 2005
We propose a scenario in which the cosmological domain wall and monopole problems are solved without any fine tuning of the initial conditions or parameters in the Lagrangian of an underlying filed theory. In this scenario domain walls sweep out (unwind)

Enhancing Organic Light‐Emitting Diode Performance Using Naturally Derived Diatomite: A Cost‐Effective and Eco‐Friendly Strategy

open access: yesAdvanced Optical Materials, EarlyView.
Diatomite‐based light extraction structures enable enhanced photon outcoupling through multi‐angle scattering and far‐field redistribution. By harnessing the unique scattering behavior of diatomite, this approach introduces randomly oriented scattering centers that effectively reshape internal light propagation.

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

open access: yesAdvanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create
