Close or not so close? Provenance studies of megalithic monuments from Alentejo (Portugal) [PDF]

open access: yes, 2012
There has been a significant amount of studies about megalithic tombs conducted in the Alentejo region. However the geological provenance of monoliths used in the construction of those tombs usually was not a priority among researchers with rare ...

Increased Endurance of Nonvolatile Photonics Enabled by Nanostructured Phase‐Change Materials

open access: yesAdvanced Materials, EarlyView.
Tapered and segmented islands of the phase‐change material (PCM) antimony selenide (Sb2Se3) integrated on silicon microring resonators enable ultra‐low‐loss, high‐endurance, non‐volatile photonic tuning. The nanostructured PCM design suppresses interfacial scattering and thermal stress, achieving record endurance over 100 million electrical switching ...

Mechanically Spatio‐Chimeric Fibrin Assembly Enables Vascular‐Integrated Muscle Reconstruction for Volumetric Muscle Loss Repair

open access: yesAdvanced Materials, EarlyView.
SPARC (spatio‐chimeric, plasma‐based, anisotropic, and shear‐responsive construct) that integrates myogenic and vascular microenvironments within a single construct. The dual‐modulus matrix directs aligned myotube formation and endothelial network development, enabling a vascularized muscle implant that seamlessly anastomoses with host tissue and ...

Structural Response of a Two-Side-Supported Square Slab Under Varying Blast Positions from Center to Free Edge and Beyond in a Touch-Off Explosion Scenario

open access: yesBuildings
A touch-off explosion on concrete slabs is considered one of the simplest yet most destructive forms of adversarial loading on building elements. It causes far greater damage than explosions occurring at a distance.

Spin‐Orbit Torque Induced by Switchable Crystal Inversion Symmetry Breaking

open access: yesAdvanced Materials, EarlyView.
An exotic crystal inversion symmetry breaking in SrRuO3/BiFeO3 heterostructure is revealed, and it can be reversibly manipulated by the ferroelectric polarization of BiFeO3. This crystal inversion symmetry breaking can dramatically enhance the spin‐orbit torque efficiency in the SrRuO3 layer by more than 60%, providing an alternative to design an ...

Behavior of one-way steel, BFRP, and GFRP reinforced concrete slabs under monotonic and cyclic loadings: Experiments and analyses

open access: yesCase Studies in Construction Materials
This paper experimentally investigated the monotonic and cyclic behaviour of one-way basalt and glass fibre-reinforced polymers (BFRP and GFRP) reinforced concrete (RC) slabs compared with that of traditional steel RC ones.

Behaviour of composite floor slabs under fire conditions [PDF]

open access: yes, 2015
This paper is concerned with the ultimate behaviour of composite floor slabs during fire scenarios. Steel/concrete composite structures are increasingly common in the UK and worldwide, particularly for multi-storey construction.

Additive Manufacture of Diamond:Titanium Hybrid Quantum Sensors

open access: yesAdvanced Materials Interfaces, EarlyView.
ABSTRACT Additive manufacture represents one of the most advanced techniques for the creation of complex parts for applications as diverse as aerospace and implant surgery. However, a challenge with bespoke manufacture of metal parts is the incorporation of sensor elements in a fashion compatible with the 3D printing process.

Comparative Study on Carbon Emissions and Economics of Three Types of Slab Systems in the Materialization Stages

open access: yesEnergies
As one of the most important sources of carbon emissions, the construction industry consumes approximately 30% to 40% of global energy and emits about 30% of global greenhouse gases.

Simulation and comparative analysis of waste in concrete slabs [PDF]

open access: yes, 2014
Construction sector generates significant amounts of waste that affects the environment and obstructs a sustainable development. The horizontal structure (slabs and roofs) is one of the building elements, by its functional requirement (geometry and ...
