Additive Manufacturing of Multimetallic Materials to Achieve Multifunctionality

MetalMat, EarlyView.
Leveraging multimaterial directed energy deposition (DED), this work showcases four case studies of metallic multifunctional materials (MFMs). The significant potential of DED to achieve multifunctionalities in metallic materials is demonstrated, providing enlightenment to a wide range of engineering applications unseen in conventional metallic ...

Security bounds in Quantum Cryptography using d-level systems [PDF]

, 2003
We analyze the security of quantum cryptography schemes for $d$-level systems using 2 or $d+1$ maximally conjugated bases, under individual eavesdropping attacks based on cloning machines and measurement after the basis reconciliation.

Prediction of the Mechanical Properties of the Additive Friction Stir‐Deposited Al2219 Using Machine Learning

Materials Genome Engineering Advances, EarlyView.
In this work, three prediction machine learning (ML) models (MLP, RBF, BP) are developed to predict the ultimate tensile strength (UTS) and elongation (EL) of the AFSDed Al2219 samples. ABSTRACT Additive friction stir deposition (AFSD) is an effective method for fabricating high‐performance deposits, with process parameters directly influencing the ...

Social and cultural considerations for the restoration of ‘lost’ tree species: The fall and rise of elm

People and Nature, EarlyView.
Abstract Attempts to address biodiversity loss have led to ecosystem and species restoration efforts. Tree species restoration is particularly relevant because of increasing threats from pests and pathogens. However, there are different notions of ‘loss’, as well as sociocultural considerations, including social acceptability, which are often neglected

Sex Ratios at Birth Following Non‐Invasive Prenatal Testing in Victoria, Australia

Prenatal Diagnosis, EarlyView.
ABSTRACT Objective Non‐invasive prenatal testing (NIPT) can determine fetal chromosomal sex early in pregnancy, raising the possibility of sex selection. However, current evidence regarding this practice is limited. Our objective was to assess the sex ratio at birth (SRB) among a cohort of infants born following NIPT from a single laboratory provider ...

Outdoor Measurements of Perovskite Modules

Progress in Photovoltaics: Research and Applications, EarlyView.
Performance of a single junction perovskite module (total area of 0.7164 m2) during 1 year of outdoor monitoring. ABSTRACT For the PSC PV to be a competing technology with silicon and thin film PV technologies more data from field installations need to be studied and examined.

Twin‐Wire In Situ Additive Manufacturing of NiTiNb Eutectic Alloys: Eliminating Unmelted Nb Particles and Tailored Superelasticity

Rare Metals, EarlyView.
ABSTRACT A major challenge in fabricating eutectic NiTiNb alloys is the incomplete melting of Nb due to its much higher melting point than the NiTi matrix. In this work, a novel electron‐beam freeform additive manufacturing strategy is developed to eliminate unmelted Nb particles and achieve a fully eutectic structure through independent dual‐wire ...
