Investigation of the failure characteristics of fissure tunnels under dynamic and static combinations

Deep Underground Science and Engineering, EarlyView.
This article aims to investigate the dynamic fracture response of fractured tunnel models under zero geological stress through physical experiments and numerical simulations. It further simulates the dynamic fracture characteristics of fractured tunnel models under geological stress ranging from 0 to 2.5 MPa using the numerical software AUTODYN ...

Creep properties and constitutive model of diabase in deep water conveyance tunnels

Deep Underground Science and Engineering, EarlyView.
The axial and lateral creep characteristics of diabase were analyzed based on compression creep tests. The nonlinear viscoelastic‐plastic model capable of describing the whole creep process was established based on the fractional derivative and damage theories.

Colossal Barocaloric Effects at Triple‐Phase Points

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Colossal barocaloric effects were achieved in odd‐numbered normal alkane systems, such as C17H36, C19H40 and C21H44 approaching triple‐phase point by overlapping two separated phase transitions of ordered‐disordered solid phase transition and solid–liquid phase transition under a relative low pressure.

Halloysite‐Based X‐Ray‐Activated Persistent Luminescent Hydrogels Enable Multiple‐Level Encryption and Dual‐Locked Camouflage

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
X‐ray‐activated persistent luminescent hydrogels with self‐healing properties were facilely developed based on the plasma‐assisted surface modification of halloysite nanotubes. Exploring multiple‐level encryption technologies and extra safety decoding ways to prevent information leakage is of great significance and interest, but is still challenging ...

Dielectrophoresis Tutorial: Inspired by Hatfield's 1924 Patent and Boltzmann's Theory and Experiments of 1874

ELECTROPHORESIS, EarlyView.
ABSTRACT The first patent to describe dielectrophoresis (DEP) as a means and process to separate particles from a mixture was granted by the US Patent Office to Henry Stafford Hatfield in 1924. The novel methods of sample preparation and designs of electrode geometry covered by the patent's disclosures and claims describe the basis for most present‐day
