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

Stability control of surrounding rocks for a coal roadway in a deep tectonic region

International Journal of Mining Science and Technology, 2014
Abstract In order to effectively control the deformation and failure of surrounding rocks in a coal roadway in a deep tectonic region, the deformation and failure mechanism and stability control mechanism were studied. With such methods as numerical simulation and field testing, the distribution law of the displacement, stress and plastic zone in the

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.

Nanofiber‐Supported Decellularized Matrix Membrane Creates a Biomimetic Biochemical and Biophysical Niche for Intestinal Organoid Epithelium

Advanced Healthcare Materials, EarlyView.
A nanofiber‐supported decellularized extracellular matrix (NaDE) membrane recreates key biochemical and mechanical features of native intestinal tissue. This platform enables the formation of a more physiologically relevant intestinal epithelium, enhancing stem cell maintenance and promoting diverse cell differentiation.

Theory and complete technology for collaborative control of surrounding rock in deep coal mine roadways

Meitan xuebao
China is rich in deep coal resources. With the continuous depletion of shallow coal resources, deep coal mining is imperative. Currently, over 40 coal mines in China have reached or exceeded a mining depth of 1 000 meters, with the deepest reaching 1 510

Study on Sensitivity Parameters Analysis of Grouting Reinforcement Underpassing Existing Subway Tunnel by Numerical Modeling

Advances in Civil Engineering, 2021
When carrying out construction that underpasses existing subway tunnels, the surrounding rock is frequently disturbed. Therefore, it can loosen easily and become unstable, which makes its stability difficult to control.
