Emergent Freestanding Complex Oxide Membranes for Multifunctional Applications

Advanced Materials, Volume 38, Issue 16, 17 March 2026.
This review surveys freestanding oxide membranes and covers fabrication and three pathways for studies and devices: strain‐free and strained membranes, and van der Waals‐integrated heterostructures. We show how coupled oxide responses map onto these routes and cross‐couple to expand behaviors.

Self‐Assembled Fluorescent Nanodiamond Layers for Quantum Imaging

Advanced Materials Interfaces, Volume 13, Issue 5, 4 March 2026.
We developed a simple, scalable method for coating surfaces with fluorescent nanodiamonds. By optimizing the coating process, we created uniform, dense layers that enable high‐resolution magnetic imaging using the nitrogen‐vacancy (NV) center in nanodiamonds. This approach enables the development of cost‐effective quantum‐sensing and imaging substrates

Cellulose‐Nanofiber‐Based Layered Sub‐Terahertz Absorbing Sheets for B5G/6G Applications

Advanced Materials Technologies, Volume 11, Issue 5, 6 March 2026.
We report a sub‐terahertz absorber made of biodegradable cellulose‐nanofiber (CNF), potentially useful for B5G/6G devices to achieve electromagnetic compatibility in an eco‐friendly way. The absorber is 120 µm thick and consists of two carbon‐nanotube‐dispersed CNF layers and one pure CNF layer.

Contactless Terahertz “Fiber Squeezer” for Tunable Dispersion Engineering in Unclad Silicon Dielectric Waveguides

Advanced Photonics Research, Volume 7, Issue 3, March 2026.
Terahertz microscale silicon waveguides can be wholly unclad, making it possible to interact with guided waves contactlessly via evanescent fields. We exploit this with conductive walls that enforce a movable field‐null upon modal fields, enabling tunable dispersion and cutoff similar to a fiber squeezer, albeit without physical contact.

Ultra‐Efficient 0.1 V cm Lithium Niobate Modulator with >$\gt$ 200 GHz Bandwidth Using a High‐Permittivity Bragg Waveguide

Advanced Photonics Research, Volume 7, Issue 3, March 2026.
This work demonstrates thin‐film lithium niobate Mach–Zehnder modulators. One of these modulators achieves a voltage‐length product of 0.1 V cm, a driving voltage of 1 V, a device length of 1 mm, and a bandwidth exceeding 200 GHz. A high‐permittivity cladded Bragg grating waveguide is utilized to enhance modulation efficiency, enabling low‐voltage and ...
