The Dynamic Characteristics of Railway Portal Frame Bridges: A Comparison between Measurements and Calculations

Applied Sciences
Railway bridges are subjected to significant dynamic loads. A numerical model of the bridge structure that captures its dynamic characteristics as accurately as possible is essential for the simulation of train crossings.

Analyses on Prestress Loss and Flexural Performance of the Laminated Bamboo Beam Applied with Prestressed BFRP Sheet

Advances in Civil Engineering, 2019
Inspired by the studies about wooden beam applied with prestressed steel plate and bamboo beam strengthened by fiber-reinforced polymer (FRP), this paper aims to explore the applicability of the prestressed basalt fiber-reinforced polymer (BFRP) sheet to

Comparison of compressive strength in mud bricks with shred tires and concrete particles as sustainable materials [PDF]

, 2010
Mud bricks consist of clay, water and different materials. Comparing mud bricks to concrete blocks, an evolution in reducing the cost and also in increasing the compressive strength, can be made.

Interface‐Induced Stability of Nontrivial Topological Spin Textures: Unveiling Room‐Temperature Hopfions and Skyrmions

Advanced Materials, EarlyView.
The first room‐temperature, zero‐field observation of stable skyrmion–hopfion spin textures in EuS─Bi2Se3─EuS trilayers is reported. Combining Lorentz TEM imaging and micromagnetic modeling, the authors unveil how interfacial Dzyaloshinskii–Moriya interaction and geometric confinement stabilize these multidimensional topological states.

Analysing development to shape the future [PDF]

, 2008
This article links theory and politics in a systematic way by proposing Is-Shall-Do as a didactical model for analysing a concrete conjuncture, relating it to the desired future in the form of a concrete utopia.

Lithographically Controlled Liquid Metal Diffusion in Graphene: Fabrication and Magnetotransport Signatures of Superconductivity

Advanced Materials, EarlyView.
Lithography‐guided intercalation creates a proximitized 2D superconducting Ga layer under graphene Hall bars via liquid‐metal intercalation. The image shows a Hall bar where Ga atoms from the liquid phase enter through patterned intercalation channels beneath quasi‐freestanding bilayer graphene, forming a confined 2D metal that demonstrates ...
