Ultra‐Improved Interfacial Strength Between Metallic Surface and Polyurethane via Cost‐Effective Anodizing Process

Advanced Materials Interfaces, EarlyView.
SAA significantly enhanced Al/PU bonding, increasing SLSS by up to 920% and fracture energy by 15 100% through optimized micro‐nano porous surfaces. RSM identified the optimal anodizing conditions, while ML confirmed sulfuric acid concentration and roughness as dominant predictors of strength.

Development of Laterally Graded X‐Ray Multilayer Optics

Advanced Materials Technologies, EarlyView.
This work presents the development of laterally graded X‐ray multilayer optics with both constant and variable lateral gradients. By precisely controlling substrate speed profiles and mask design, these multilayers achieve highly accurate lateral gradients and excellent sagittal thickness uniformity, making them ideal for spectroscopy application at ...

4D Printing of Multimaterial Flexible Magneto‐Active Polymers

Advanced Materials Technologies, EarlyView.
Magneto‐active polymers are 3D‐printed with tunable mechanical and magnetic properties using both superparamagnetic and hard ferromagnetic fillers. Nano‐CT imaging reveals the spatial distribution of particles within the matrix. Programmable magnetization patterns and soft, flexible architectures enable responsive actuation, offering exciting ...

Fiber Bragg Gratings with Micro‐Engineered Temperature Coefficients

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
Fiber Bragg gratings (FBGs) are intrinsically responsive to temperature and strain simultaneously. In this research, low‐loss FBGs with micro‐engineered temperature coefficients are fabricated, utilizing refractive index liquid‐filled microchannels in the cladding.

Enhanced Scintillation with Uncorrelated TL and OSL Signals in LiCaAlF6:Eu Nanoparticles Enables Unprecedented Multimodal Radiation Dosimetry

Advanced Optical Materials, EarlyView.
The graphical abstract illustrates the coexistence of independent OSL and TL signals, demonstrating that the material preserves TL information even after complete OSL zeroing, enabling a dual dosimetric readout within the same material. Abstract The development of multimodal dosimeters capable of preserving independent luminescent signals is a ...

Mitigating Singlet Exciton Back‐Transfer using 2D Spacer Layers for Perovskite‐Sensitised Upconversion

Advanced Optical Materials, EarlyView.
The efficiency of bulk perovskite‐sensitised upconversion is hindered by parasitic singlet back‐transfer. A 2D perovskite spacer layer is introduced to weaken this loss pathway by increasing the separation between the sensitiser and the emitter. The spacer layer enhances the upconversion efficiency at lower excitation powers and improves the stability ...
