Eco‐Fabricated Nanowave‐Textured Implants Drive Microtubule‐Assisted Nuclear Mechanotransduction and Chromatin Modification: Biophysical Priming for Osteogenesis and Bone Regeneration

Advanced Functional Materials, EarlyView.
Eco‐friendly nanowave‐textured implants produced via femtosecond laser fabrication enhance bone regeneration by orchestrating a precise mechanotransduction cascade. This nanotopography directs mesenchymal stem cell alignment and cytoskeletal organization, triggering changes in nuclear shape and chromatin acetylation that prime cells for osteogenesis ...

A Vertically‐Stacked Optoelectronic Sensor for Localized Hemodynamics Monitoring

Advanced Functional Materials, EarlyView.
This work introduces a hemodynamics monitoring sensor that features vertically stacked microLEDs and a heterogeneously integrated photodetector. The vertically stacked microLEDs enable localized measurements, and by designing the interoptode distance according to the depth of the target region, this vertically stacked optoelectronic sensor is ...

Optical Whispering‐Gallery Mode as a Fingerprint of Magnetic Ordering in Van der Waals Layered CrSBr

Advanced Functional Materials, EarlyView.
A novel nanoscale optomagnetic sensing approach is developed using whispering‐gallery mode resonances in a self‐rolled‐up microcavity. This method enables ultra‐sensitive detection of weak magnetism by correlating resonance shifts with magnetic susceptibility.

Ultrahigh‐resolution (λ/10) Femtosecond Laser Writing of Polymer‐Encapsulated Multicolor Perovskite Patterns Beyond the Diffraction Limit

Advanced Functional Materials, EarlyView.
Fabrication of in situ polymer‐encapsulated stable perovskite patterns of arbitrary shapes and pixel arrays with a resolution of 80 nm is reported by the femtosecond (fs) laser (800 nm) super‐resolution writing technique. The two‐photon absorption‐induced laser ablation is attributed to the achieved feature sizes as small as λ/10.

Raith - Electron Beam Lithography for Research

Acta Physica Polonica A, 2009
Electron beam lithography is one of the enabling methods in advanced nanoresearch. Electron beam lithography is a maskless lithography technique which is therefore very flexible. Electron beam lithography provides very high resolution. This is the main reason of its wide use in nanoresearch [1].

Field‐Free Spin–Orbit Torque Switching of Perpendicular Magnetization by PtTe2/WTe2 Bilayers at Sub‐ns Timescales

Advanced Functional Materials, EarlyView.
This work demonstrates ultrafast, field‐free spin–orbit torque (SOT) switching using a PtTe2/WTe2/CoFeB multilayer, achieving sub‐nanosecond magnetization reversal with record‐low energy consumption. The PtTe2/WTe2 bilayer generates an intrinsic out‐of‐plane spin current, enabling deterministic switching without external fields.
