Impact of twisting high-performance polyethylene fibre bundle reinforcements on the mechanical characteristics of high-strength concrete

open access: yesMateriales de Construccion, 2019
The quasi-static and dynamic mechanical behaviours of the concrete reinforced by twisting ultra-high molecular weight polyethylene (UHMWPE) fibre bundles with different volume fractions have been investigated.

Optimising the Workability and Strength of Concrete Modified with Anacardium Occidentale Nutshell Ash

open access: yesFibers, 2021
Strength failure persists both in structural and mechanical analysis. One of its prominent characteristics is the adequate provision for parameters that minimise or maximise strength objectives while satisfying boundary conditions.

Study of Mortars Made with Natural and Artificial Pozzolans [PDF]

open access: yes, 2019
The objective of this work is to evaluate the thermal activation potential of clay soils, particularly the clay fraction of dam mud, for the production of artificial pozzolan which can be substituted to cement in concrete and mortars applications and ...

An Injection‐Molded Modified Silicone Rubber for Cancer‐on‐Chip Applications

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This study describes the characterization and application of an injection‐molded functionalized PDMS fluidic insert for the commercially available Micronit system. Modified PDMS can accommodate cell culture and is able to covalently bind proteins for long‐lasting coatings under flow‐conditions.

Advancements in TLP Bonding for Power Electronics Die‐Attach Applications

open access: yesAdvanced Materials Technologies, EarlyView.
Transient Liquid Phase (TLP) bonding is gaining traction as a lead‐free die‐attach technology in power electronics packaging. This review examines the state of TLP bonding, its key elements, reliability aspects, and practical limitations. This review also highlights emerging trends, such as nanostructured interfaces, that may improve scalability of TLP

Use of superabsorbent polymers to mitigate autogenous shrinkage in ultra-high performance concrete [PDF]

open access: yes, 2019
Ultra-high performance concrete (UHPC) with low w/c-ratio is very prone to the formation of cracks due to autogenous shrinkage. These cracks can lead to a decreased durability of the concrete, resulting in higher maintenance and/or repair costs in the ...

Fracture behaviour of alloys for a new laser ranged satellite [PDF]

open access: yes, 2018
A new laser-ranged satellite called LARES 2 (Laser Relativity Satellite 2) has been recently designed for accurate tests of Einsten's theory of General Relativity and space geodesy.

Design of a Cobalt‐Free Maraging Steel with Ultra‐High Strength of 2.3 GPa Through Additive Manufacturing

open access: yesAdvanced Science, EarlyView.
A computationally designed, cobalt‐free maraging steel tailored for additive manufacturing achieves an ultra‐high tensile strength of 2.3 GPa with 5.7% elongation. This exceptional strength‐ductility synergy stems from high‐density core‐shell Ni3Ti/NiAl nanoprecipitates, a crack‐resistant composition, and a fine equiaxed grain structure enabled by ...

Fresh and hardened properties of self-compacting concrete with different mineral additions and fibers

open access: yesJournal of Building Materials and Structures, 2016
In this work, several reinforced self-compacting concretes were prepared by using three types of fibers made of steel, polypropylene and glass, and three different types of mineral additions (marble powder, metakaolin and limestone powder).
