THE DESIGN AND THE STUDY OF A PRE-STRESSED CONCRETE BEAM BRIDGE PK7

open access: yes
L'objet de ce mémoire de master porte sur la conception et l'étude d'un pont à poutres en béton précontraint situé dans la wilaya d'El-Bayadh en Algérie, PK7. Il existe deux conditions de franchissement, mais dans notre étude de thèse, nous nous concentrerons sur la condition de franchissement où le pont passe au-dessus d'une voie ferrée et non en ...

Electrolyte Design for Simultaneous Interfacial Stabilization in Si||NCM811 Full Cells

open access: yesAdvanced Science, EarlyView.
A dual‐additive electrolyte (DAEL) system was optimized to regulate interfacial reactions in both Si anode and the NCM811 cathode. DAEL suppresses gas evolution and degradation, enabling stable interphases. These synergistic effects enhance electrochemical stability and extend battery cycle life in high‐energy lithium‐ion cells.

Micro‐Galvanic Coupling Programs the Therapeutic Zinc Ion Window to Reconfigure Immune Cascades for Pro‐Regenerative Bone Healing

open access: yesAdvanced Science, EarlyView.
This study utilized alloy micro‐galvanic coupling design to regulate the release of essential elements, thereby programming immune responses and promoting regeneration. The sacrificial anodic process of Zn‐0.8Mg reduced Zn2+ release compared to the “large cathode‐small anode” coupling of Zn‐0.8Fe.

Graphene (0002)/Diamond (111) Heterojunction with High Piezoresistive Response

open access: yesAdvanced Science, EarlyView.
Graphene/diamond heterostructures show promise as silicon alternatives for semiconductors, but high‐quality integration is challenging. Thermal electron irradiation enables covalent bonding; lonsdaleite acts as an intermediate. The heterostructure exhibits a high piezoresistive response (gauge factor −1149) associated with electron‐rich layers and ...

Real‐Time Stress Visualization of Hydrogels Enabled by Supramolecularly Switched Stretch‐Induced Phase Separation

open access: yesAdvanced Science, EarlyView.
Supramolecular hydrogels enable real‐time visualization of mechanical stress through supramolecular switching mechanotransduction. Adamantane‐modified cellulose functions as a responsive domain that undergoes an on–off transition between hydrated and dehydrated states via reversible β‐cyclodextrin–adamantane complexation and decomplexation.

Rod Origami (RodOri) Spring Metamaterials for Tunable Vibration Control via Tailored Structural Instabilities

open access: yesAdvanced Science, EarlyView.
Rod Origami (RodOri) springs harness snap‐through instabilities of pre‐stressed curved rods with geometrically programmable buckling behavior. Integrating RodOri springs with distinct geometries yields multistable metamaterials that undergo stepwise reconfiguration via sequential snapping, achieving wide‐range tunability of stiffness and resonance ...
