Stability Implications of Non-Persistent Joints in Large-Section Tunnel Sourrounding Rock

Romanian Journal of Transport Infrastructure
In the construction of large-span tunnels, the degree of joint development within the surrounding rock demonstrates heightened sensitivity and exerts a critical influence on the stability of the rock mass. To gain deeper insight into the influence of non-

Conformational Switching of Proteins on Material Surfaces Enabled by Peptide‐Oriented Adsorption

Advanced Functional Materials, EarlyView.
Responsive biointerfaces could be achieved using conformationally responsive proteins; however, their interconversion can be lost upon surface adsorption. Herein, we demonstrate that the incorporation a Au binding peptide into calmodulin allows for binding control on Au wherein the protein retains conformational switching. This capability was confirmed

Electrostatic Superlattices Beyond 1:1 Stoichiometry

Advanced Functional Materials, EarlyView.
Polymer‐mediated charge regulation drives two hierarchical routes to higher‐stoichiometry nanoparticle superlattices. Tuning the polymer's molecular weight promotes progressive interstitial filling, transforming ZnS into the fully occupied CaF2${\rm CaF}_2$ lattice. Exchanging polymer assignment between large and small nanoparticles instead breaks CsCl

Domain Engineering and Anisotropic Domain‐Wall Photovoltaic Effects in Ferroelectric SnS

Advanced Functional Materials, EarlyView.
The bulk photovoltaic effect at domain walls in the in‐plane ferroelectric 2D semiconductor SnS is investigated using periodic domain structures. Unlike conventional oxide ferroelectrics, domain walls of SnS do not contribute to photocurrent generation perpendicular to the domain walls.

Influence of in-situ rock stress on the stability of roadway surrounding rock: a case study

Journal of Geophysics and Engineering, 2019
Abstract In-situ rock stress was measured in the development roadway of Gucheng coal mine at +420 m level by using the stress relief method of hollow inclusion. The results show that the first principal stress was the vertical stress, the maximum horizontal principal stresses were distributed in the range of N10°E and N20°E, and the ...
