Vegetation and climate reconstruction during the Last Interglacial Complex: the pollen record of Lake Ohrid (Albania/Fyrom), the oldest European lake [PDF]

open access: yes, 2017
This thesis is focussed on the palaeonvironmental and climatic changes occurred during the period between 130 and 70 ka (including the whole Last Interglacial Complex), with the aims to investigate the long-term climate variability on environment, on the

A Visible Light‐Responsive Hydrogel to Study the Effect of Dynamic Tissue Stiffness on Cellular Mechanosensing

open access: yesAdvanced Functional Materials, EarlyView.
A visible light‐responsive polyacrylamide‐azobenzene hydrogel enables safe, reversible stiffness control for studying cell mechanobiology without harmful UV exposure. This approach reveals stem cells respond rapidly to mechanical changes, showing altered shape and protein distribution within one hour.

The Influence of Physical Features upon the History of Rhode Island [PDF]

open access: yes, 1910
To affirm that the physical features of the State of Rhode Island have influenced its history is not to deny that the character of its early settlers has exerted an equal, or perhaps a greater influence.

Tunable Thermoshrinkable Hydrogels for 4D Fabrication of Cell‐Seeded Channels

open access: yesAdvanced Functional Materials, EarlyView.
A thermoresponsive polymer with methacrylate groups for photo‐cross‐linking, based on polyethylene glycol, N‐isopropylacrylamide, and 2‐hydroxyethyl acrylate is synthetized to yield hydrogels that shrink upon temperature increase. The new polymer enables the fabrication of cell‐laden perfusable channels with diameters below 200 µm by combining ...

Magnetically Guided Mechanoactive Mineralization Scaffolds for Enhanced Bone Regeneration

open access: yesAdvanced Functional Materials, EarlyView.
A 3D‐printed ‘rebar‐concrete’ inspired scaffold (PGS‐P@MGel) synergizes spontaneous biomineralization with magneto‐mechanical stimulation through PDA@Fe3O4‐embedded hydrogel. This dual biointerface activates Piezo1/β‐catenin/YAP mechanotransduction axis, enhancing BMSCs osteogenesis and angiogenesis simultaneously.

Comprehensive Si Anode Design for Sulfide‐Based all‐Solid‐State Batteries: Insights into Si‐Electrolyte Synergy for Mitigating Contact Loss

open access: yesAdvanced Functional Materials, EarlyView.
Silicon anodes in sulfide‐based all‐solid‐state batteries suffer from interfacial instability caused by volumetric fluctuations and contact degradation, restricting their practical implementation despite high capacity. This study presents design strategies that leverage controlled active material expansion and an elastic recoverable anolyte to form an ...
