A Novel Prediction Model for Estimating Ground Settlement Above the Existing Tunnel Caused by Undercrossing

open access: yesBuildings
A new tunnel undercrossing an existing tunnel not only affects the deformation and stress response of the existing tunnel but also triggers ground settlement due to secondary excavation disturbances.

Swelling‐Programmed Topographical Guidance for Dynamic Spheroid Self‐Assembly via a Mechanochemical Hydrogel Niche

open access: yesAdvanced Functional Materials, EarlyView.
A swelling‐programmed micropatterned hydrogel guides adherent cells through a controlled transition from cell–matrix anchoring to cadherin‐mediated cell–cell compaction, enabling rapid assembly of high‐viability spheroids with defined size and morphology.

Effect of Lubricant Young’s Modulus on Surface Settlement Control During Pipe-Roof Construction Using Pipe-Jacking Method

open access: yesApplied Sciences
During pipe-roof construction using pipe-jacking technology, lubricants are injected into the tail void to reduce pipe–soil friction and minimize soil loss. However, research on ground settlement caused by multiple adjacent pipe jackings remains limited,

Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies

open access: yesAdvanced Functional Materials, EarlyView.
Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...

Consolidation Solution for Sand-drained Ground with Impeded Boundaries Under Vacuum Preloading

open access: yes工程科学与技术, 2018
Since the cushion generally exists on the top and a substratum below the bottom of sand-drained ground,impeded boundaries were used to describe its effect on consolidation process of sand-drained ground.Assuming that ground deformation satisfies the ...

Analysis of ground settlement caused by tunnel construction

open access: yesGrađevinar, 2012
Prediction of ground settlement is considered as highly significant in the design of tunnels located in urban areas. 2D and 3D modelling of tunnel construction, as needed for settlement analysis, is made according to the finite-element method. The ground

A Novel Modified Petroresin Particle (MPRP) With Enhanced Oil–Water Selectivity for Cold Production in Heavy Oil Reservoirs

open access: yesAdvanced Functional Materials, EarlyView.
A novel oil–water selective conformance control agent, MPRP, is prepared via hydrophilic grafting and mechanical granulation. MPRP uniformly disperses in water, cohesively expands upon aging, and readily dissolves in the oil phase. During conformance control, it selectively aggregates in water channeling pathways to form effective plugs without ...

Tuning Mechanoreceptor Signaling Enhances the Adjuvant Effect of Biomaterial Vaccines

open access: yesAdvanced Functional Materials, EarlyView.
Matrix stiffness serves as an independent immunological signal in biomaterial vaccines. Stiffer microporous hydrogel vaccines enhance dendritic cell maturation and migration to draining lymph nodes, promote T follicular helper cell expansion through Yap/Taz signaling, and increase antigen‐specific antibody production.
