Turning Light Into Matter: Programmable Microstructures Via Dose Control in Two‐Photon Polymerization

open access: yesAdvanced Optical Materials, Volume 14, Issue 37, 9 October 2026.
This work augments two‐photon polymerization with point‐wise dose control, enabling structures with heterogeneous material properties such as refractive index. An open source toolbox and superior calibration methodology for the refractive index pave the way for bio‐mimicking or numerically optimized structure designs, and enhance the synergy between 3D

Bond Strength of Injectable Composites Under Different Enamel Treatments and Bonding Strategies

open access: yesClinical and Experimental Dental Research, Volume 12, Issue 5, October 2026.
ABSTRACT Objective The effectiveness of enamel acid etching may be enhanced when combined with additional surface treatments, such as diamond bur grinding. However, there are no reports of the effect of enamel grinding and bonding strategies when a universal adhesive and highly filled flowable composites are used.

Small Proteoglycans, Big Impact: Decorin, Biglycan, and Asporin in Musculoskeletal Tissue Health and Disease

open access: yesProteoglycan Research, Volume 4, Issue 4, October 2026.
ABSTRACT The extracellular matrix (ECM) is a dynamic and information‐rich network that integrates structural support with biochemical and mechanical signaling. Among its key regulatory components are the Small Leucine‐Rich Proteoglycans (SLRPs), a family of matrix molecules that coordinate extracellular architecture with cell signaling.

Eutectic Topology Regulates Deformation Pathways Enabling Synergistic Superelasticity and Strength in EBF3‐Fabricated NiTiNb Alloys

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT The deformation behavior of NiTiNb shape memory alloys is governed by microstructural heterogeneity, specifically the interconnected topology of the β‐Nb phase. The regulatory role of the eutectic structure in load partitioning and the evolution of deformation mechanisms, particularly in high‐Nb systems, has not been clearly understood.

Nanosecond, Nanometer Movies of MEMS/NEMS Dynamics in a Standard SEM Using Time‐Tagged Secondary Electrons

open access: yesSmall Methods, Volume 10, Issue 19, 7 October 2026.
For the observation of micromechanical devices, a fast imaging technique with high temporal resolution is needed. Here, we demonstrate that a standard scanning electron microscope can be converted into a time‐resolving instrument using a fast detector and a time‐to‐digital converter.

Core–Shell Confinement Blocks Hydride Formation: The Impact of Surface Oxides on Hydrogen Sorption in Nanoporous TiFe

open access: yesSmall Structures, Volume 7, Issue 10, October 2026.
Nanoporous and ultrafine porous TiFe is prepared via high‐pressure torsion, annealing, and selective phase dissolution. Microstructural characterization, combined with hydrogen sorption, in situ X‐ray diffraction, and analytical modeling, suggests that hydride formation is blocked in nanoporous TiFe due to a confinement effect originating from the ...
