The Influence of the Structural Architecture on the Swelling Kinetics and the Network Behavior of Sodium-Alginate-Based Hydrogels Cross-Linked with Ionizing Radiation [PDF]

open access: yesGels
The present work discusses the influence of the structural architecture of sodium alginate–co-acrylic acid–poly(ethylene) oxide hydrogels, crosslinked through electron beam (e-beam) radiation processing.

Integrated structured light architectures [PDF]

open access: yesScientific Reports, 2021
AbstractThe structural versatility of light underpins an outstanding collection of optical phenomena where both geometrical and topological states of light can dictate how matter will respond or display. Light possesses multiple degrees of freedom such as amplitude, and linear, spin angular, and orbital angular momenta, but the ability to adaptively ...

The issue of residual stresses in additive technologies [PDF]

open access: yesMATEC Web of Conferences, 2023
The paper considers the issue of residual stresses in 3D-printed plastic models. Most additive technologies create residual stresses in products. Residual stresses occur in the printed material due to its expansion when heated and contraction when cooled.

Influencing factors to the capillary water uptake of (un)cracked cementitious materials [PDF]

open access: yesMATEC Web of Conferences, 2023
Capillary water absorption tests are widely used in uncracked cementitious materials to assess the quality and durability. Due to the easy execution of the test, it is also frequently used to assess the self-healing efficiency of self-healing concrete ...

Peptidoglycan structure and architecture [PDF]

open access: yesFEMS Microbiology Reviews, 2008
The peptidoglycan (murein) sacculus is a unique and essential structural element in the cell wall of most bacteria. Made of glycan strands cross-linked by short peptides, the sacculus forms a closed, bag-shaped structure surrounding the cytoplasmic membrane.

Digitally fabricated ribbed concrete floor slabs: a sustainable solution for construction

open access: yesRILEM Technical Letters, 2022
The concrete used in floor slabs accounts for large greenhouse gas emissions in building construction. Solid slabs, often used today, consume much more concrete than ribbed slabs built by pioneer structural engineers like Hennebique, Arcangeli and Nervi.
