Electrodeposition in Structural Lattices of Variable Architectures

Advanced Engineering Materials, EarlyView.
Electrodeposition enables geometry‐sensitive, autonomous void filling while simultaneously tuning chemical and mechanical properties. The development of approaches that can autonomously fill and heal material voids and yield composites with tailorable properties is increasingly relevant in engineering.

Experimental Study for Shear Behavior of Hybrid Self-Compacting Concrete Beams

Journal of Engineering and Sustainable Development, 2013
This paper discusses shear behavior of hybrid reinforced concrete beams that consist of two different concrete layers: the tension layer is made of normal strength concrete with compressive strength of 25 MPa and the compression layer is made of self ...

Study on High-Temperature Behavior of Coal Gangue-Based Geopolymer Concrete Beams

Advances in Civil Engineering, 2022
A newly coal gangue-based geopolymer concrete made from alkaline dry powder activator, coal gangue, and fly ash has been proposed by the authors. High-temperature behavior of the proposed geopolymer concrete beams with different cross sections reinforced

Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

Advanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Architecture‐Driven Functional Coupling in Vertically Aligned Nanocomposites

Advanced Functional Materials, EarlyView.
Vertically aligned nanocomposites define a growth‐engineered architecture in which vertical interfaces, strain fields, defect pathways, and phase connectivity are created simultaneously. This review shows how these architectural features couple ferroic, optical, ionic, electrochemical, and device responses, establishing design rules and open challenges

BEHAVIOR 0F HIGH STRENGTH CONCRETE BEAMS USING RISEN EPOXY

Al-Qadisiyah Journal for Engineering Science, 2011
Reinforced concrete beams for high-strength concrete often exhibit structural and nonstructural cracking due to variety steel reinforcement. Four reinforced concrete beams with dimensions of (120*230*2550)mm were investigated.

Experimental investigation and identification of single and multiple cracks in synthetic fiber concrete beams

Case Studies in Construction Materials, 2018
The tensile behavior of fiber-reinforced concrete is recognized as being superior to that of ordinary concrete, and since serviceability is a primary concern in existing design specifications, it is important to evaluate its post-cracking performance ...

Strength Behavior of Pumice Stone Lightweight Concrete Beam in Contrast with Reinforced Concrete Beam

International Journal of Recent Technology and Engineering (IJRTE), 2019
The density of concrete less than that of nominal concrete achieved by any means is referred as Light weight concrete. Circulated air through Concrete, Light Weight Aggregate Concrete, Foamed Concrete are different types of Light weight concrete. In this research study, the density of the concrete has been reduced by replacing the coarse aggregate by ...

Proximity‐Tuned Magnetic and Transport Anomalies in All‐Epitaxial Fe5−xGeTe2/WSe2 Van der Waals Heterostructures

Advanced Functional Materials, EarlyView.
All‐epitaxial and scalable ferromagnetic/non‐magnetic Fe5−xGeTe2/WSe2 van der Waals (vdW) heterostructures exhibiting room‐temperature magnetism and perpendicular magnetic anisotropy (PMA) are realized. The system displays proximity‐tuned magnetic anisotropy, thickness‐dependent unconventional Hall effects, and temperature‐dependent sign reversal of ...

Volatile Memristive Devices With Tunable Temporal Dynamics For Event‐Based Sensing

Advanced Materials, EarlyView.
Tunable volatile memristive devices can serve various neural‐inspired tasks that require different time windows of information retention. The ionic‐based volatility of the presented Pt/a‐STO/TaOx/Ta device stack can be reproducibly and controllably tuned in multiple ways.
