Film‐Based Multi‐Photon Lithography for Efficient Printing of Electromagnetic Surface Structures

open access: yesAdvanced Materials Technologies, EarlyView.
This work introduces film‐based multi‐photon lithography as an efficient method for fabricating electromagnetic surface structures with 2D and 2.5D geometries, particularly THz and mid‐IR metasurfaces. These structures can be fabricated on various substrates, such as glass or silicon‐on‐insulator, over areas ranging from mm2 to cm2, achieving feature ...

Growth Factor‐Loaded Mesoporous Silica Particles, Incorporated in Electrospun PCL Fibres, Provide Topographical and Chemical Cues for Tendon Tissue Engineering

open access: yesAdvanced Materials Technologies, EarlyView.
Electrospinning enables the hierarchical assembly of nanofiber‐based scaffolds for tissue engineering. However, encapsulated proteins often undergo structural changes. This study used mesoporous silica nanoparticles (MSNs) as protective carriers, mitigating protein denaturation and supporting controlled release.

Optimizing Metamaterial Inverse Design with 3D Conditional Diffusion Model and Data Augmentation

open access: yesAdvanced Materials Technologies, EarlyView.
A generative AI model, the 3D conditional diffusion model (3D‐CDM), is introduced to enhance the inverse design of voxel‐based metamaterials. A data augmentation technique based on topological perturbation expands the dataset, further improving generation quality and accuracy.

Hybrid Electroluminescence Device for On‐Demand Single Photon Generation at Room Temperature

open access: yesAdvanced Optical Materials, EarlyView.
New type of electroluminescent device based on hBN nanocrystals deposited on a GaN laser diode displays electrically driven emission of single photons at room temperature. Low g2(0) autocorrelation function values are achieved of < 0.2 for continuous driving and < 0.4 for on‐demand single‐photon emission.

Comparative Test of Novel Fluorescent Optical Antennas for LED‐ and Laser‐Based Optical Wireless Communications

open access: yesAdvanced Optical Materials, EarlyView.
New fluorescent optical antennas are realized and tested for diverse Optical Wireless Communication (OWC) applications. The fluorescent concentrator slabs, based on different organic fluorophores, convert and convey the digital data conveyed through intensity modulation of incoming light toward a small‐area photodiode.
