Soft Skins With Reversible Thickness Morphing: Materials, Mechanisms, and Applications

open access: yesAdvanced Materials, EarlyView.
Evolution of electronic skin (e‐skin) technologies toward adaptive, multifunctional soft skins. Phase I highlights early rigid and discrete sensory interfaces. Phase II shows the transition toward flexible, stretchable, and large‐area e‐skin. Phase III captures the emergence of computational e‐skin.

Ultrathin Hydrogel Membranes Inspired by Soap Films Enable Physiologically Relevant Breathing Lung Models

open access: yesAdvanced Materials, EarlyView.
A soap‐film inspired strategy enables the fabrication of ultrathin yet robust GelMA‐PAAm membranes for breathing lung culture. The hydrogel membrane supports long‐term cyclic deformation under air‐liquid interface conditions, enabling physiologically relevant breathing motions of engineered lung tissue culture. ABSTRACT Breathing continuously stretches

Beam Steel Frame : A Review

open access: yesInternational Journal of Scientific Research in Civil Engineering
The accuracy of structural models significantly depends on the availability of input design parameters such as the dimensions of resisting elements, material properties, joint connection details, loading conditions, etc. Today's cities reveal skies punctuated by buildings so tall and austere, even architectural tour guides experience the occasional ...

Performance of Link-To-Stub Bolted Connection in Column-Tree Moment Resisting Frames under Fire Conditions [PDF]

open access: yesJournal of Structural and Construction Engineering, 2015
Column-tree moment resisting frames, as the efficient shop-welded and field-bolted structural systems, are used in many countries. Very limited research has been carried out on such systems under fire conditions.

Behaviour of steel and steel-concrete composite beams and beam-to-column connections at elevated temperatures

open access: yes, 2007
The current research work investigates the behaviour of steel and composite beams as well as beam-to-column connections at elevated temperatures. Significant attention is needed to identify the main issues, as the behaviour is profoundly different from that at ambient temperature.

Mechanically Assisted Magnetic Actuation in Ceramic‐Based Microscrolls for Fast and Durable Soft Robotic Systems

open access: yesAdvanced Materials, EarlyView.
Ceramic‐based V2O5/Fe3O4 hybrid films are shaped into butterfly‐proboscis‐inspired microscroll actuators. Magnetic triggering initiates unrolling, while geometry‐programmed elastic strain energy drives rapid recoil, enabling fast, reversible, durable, and load‐bearing actuation under near‐field magnetic stimulation.

Resistance to Progressive Collapse Performance Analysis and Assessment of CFST-steel Beam Joints with Through-center Construct

open access: yes工程科学与技术, 2018
Incidents such as fires, explosions, and impacts may cause progressive collapse of building. Since the 20th century, as terrorist activities in the world have been increasing year by year, experts and scholars around the world have begun to pay attention
