Anchorage performance of different punching shear reinforcement elements in cracked concrete

Structural Concrete, EarlyView.
Abstract Extensive research has been conducted on the bond and anchorage behavior of reinforcement elements in concrete. While many experimental studies have focused on uncracked concrete, the anchorage performance in the presence of cracks remains insufficiently understood.

Optimizing the embodied carbon of the product stage of reinforced concrete columns

Structural Concrete, EarlyView.
Abstract The construction sector faces urgent sustainability challenges. This study quantifies the potential for reducing embodied carbon in reinforced concrete columns by optimizing concrete strength and reinforcement ratios. The interplay between concrete compressive strength (20–90 MPa), reinforcement percentages (0.2%–2.0%), and embodied carbon ...

Experimental and numerical investigation on the flexural response of GFRP‐reinforced SFRC beams

Structural Concrete, EarlyView.
Abstract In order to address the challenges related to the deformability and ductility of concrete beams reinforced with fiber reinforced polymer (FRP) bars, an alternative solution involving steel fiber reinforced concrete (SFRC) has been proposed. In the present study, a total of seven beams—including one steel‐reinforced reference beam and six glass

Three‐parameter kinematic theory for shear assessment of reinforced concrete short columns

Structural Concrete, EarlyView.
Abstract This work presents a rational kinematics‐based model for assessing the shear capacity of rectangular reinforced concrete short columns. Due to their high stiffness and brittleness, short columns are particularly vulnerable to seismic forces, often exhibiting critical failures.

Printing to Fight Antimicrobial Resistance Through Nano/Microstructured Platforms

The Chemical Record, EarlyView.
Additive manufacturing enables the rational design of structured antimicrobial platforms across multiple length scales, from nanofibrous scaffolds and droplet microreactors to 3D and 4D printed constructs. By engineering confinement, interfacial chemistry, and stimuli‐responsive release, these systems exert localized action through complementary ...

Geopolymers as a Sustainable Chemical Platform: From Building Materials to Advanced Functional Applications

The Chemical Record, EarlyView.
Geopolymers are presented as a chemically programmable platform whose properties emerge from activation chemistry, nanoscale disorder, and interfacial design. The review highlights sustainability challenges, the shift toward nanoengineered and hybrid systems, and the rise of halloysite‐based architectures enabling tunable structures across scales for ...

Electrical Breakdown Analysis of Emerging Oil–Paper Insulation Systems

High Voltage, EarlyView.
ABSTRACT This investigation addresses the effect of particulate additives on the electrical breakdown strength of the oil impregnated insulation paper system. The morphological complexity is addressed by converting data from scanning electron microscope images to a data set suitable for numerical simulation analysis. Then, by using the conventional oil‐

Game‐Based Learning Versus Model Arm Training for Intravenous Cannulation in Dental Education

European Journal of Dental Education, EarlyView.
ABSTRACT Introduction Peripheral intravenous catheterisation is a complex procedure that is primarily performed by nurses in healthcare services. Peripheral intravenous catheterisation (PIVC) is also part of the updated 2024 Core Program in the National Dental Education catalogue. This study aimed to implement this practice and to evaluate the approach
