Depth‐Resolved Photo‐Degradation of Perovskite Layer in Solar Cells Stressed Under ISOS Light‐Aging Protocol Conditions: The Role of Substrate, Electron‐Transport‐Layer and Perovskite Deposition Method

Solar RRL, Volume 10, Issue 13, 15 July 2026.
Herein, a depth‐resolved analysis of ambient‐air‐processed perovskite layers employed in carbon‐based hole‐transport‐layer‐free photovoltaics subjected to ISOS light‐aging is provided. In all cases, the light‐induced degradation is demonstrated to start near both top and buried interfaces, and spread into the bulk, affecting perovskite crystals quality,

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, Volume 11, Issue 13, 8 July 2026.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Multiscale Architecture and Mechanics of the Cell Nucleus: Implications for Disease, Bioengineering and Nanomedicine

Advanced Science, Volume 13, Issue 37, 3 July 2026.
Nuclear mechanical properties are inherently scale‐dependent, arising from a hierarchical architecture that spans DNA, chromatin, the nuclear envelope, and condensates. Experimental techniques and theoretical models are integrated into a cohesive multiscale framework linking nanoscale structural features to organelle‐level mechanical behavior.

Biomimetic Collagen Scaffolds Natural Cross‐Linking Strategies via Transglutaminase and Methylglyoxal for Skin Repair

Journal of Biomedical Materials Research Part A, Volume 114, Issue 7, July 2026.
ABSTRACT Collagen‐based scaffolds are widely used in tissue engineering for skin repair due to their biocompatibility and structural resemblance to extracellular matrix. However, rapid degradation and insufficient mechanical stability limit their effectiveness. This study investigates natural cross‐linking strategies utilizing Transglutaminase (TG) and

Investigating the Effect of Ginger‐Derived Nanovesicles on the Growth and Metabolic Activity of Bacteroides thetaiotaomicron: An Isothermal Microcalorimetric Study

Journal of Extracellular Biology, Volume 5, Issue 7, July 2026.
ABSTRACT Plant‐derived extracellular vesicles (EVs) have shown numerous health benefits, including modulation of the human gut microbiota. Herein, we employed isothermal microcalorimetry (IMC) to explore the effects of ginger‐derived nanovesicles (G‐NVs) on the growth and metabolic activity of Bacteroides thetaiotaomicron (Bt), a dominant saccharolytic
