Modular Critical Element Recycling Platform Using a Nanoporous Additively Manufactured Gyroid

open access: yesAdvanced Engineering Materials, EarlyView.
A modular recycling platform integrates 3D‐printed nanoporous gyroid structures to enable efficient critical element recovery. This system utilizes a hierarchical architecture, combining macroscopic channels with polymerization‐induced nanoscale porosity. By systematically tuning structural wall thickness and resin formulation, the platform achieves an

Lattices of Subsemivarieties of Certain Varieties [PDF]

open access: yesJournal of the Australian Mathematical Society, 1971
For all positive integers m, n, m ≤ n, let m,n denote the variety of algebras with m n-ary operations ω1, …, ωm and n m-ary operations φ1, …, φn satisfying the system of identities The varieties m,n are considered by Swierczkowski [1] and by Akataeb and Smirnov [2]. Jonsson and Tarski [3] consider m,n in the case m = 1, n = 2.

Ontology‐Aligned Structuring and Reuse of Multimodal Materials Data and Workflows Toward Automatic Reproduction

open access: yesAdvanced Engineering Materials, EarlyView.
Reproduction of stacking fault energy calculations from literature with a semi‐automated large language model‐assisted extraction procedure: extraction of simulation protocol, atomistic structures, computational parameters, and reported results, ontology alignment, knowledge graph construction and, finally, recomputation forvalidation.

Genetic variability, heritability, and genetic advance of morphological, yield related and quality traits in upland rice (Oryza Sativa L.) genotypes at pawe, northwestern Ethiopia

open access: yesCogent Food & Agriculture, 2023
The rice production in Ethiopia is less than the world’s average due to the lack of varieties with high yield potential. Evaluation of genetic variability is important in the rice breeding program for the production of high yielding varieties.

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

open access: yesAdvanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Computer two dimensional maps of loop soliton lattice systems using the new approach to the no integrability Aesthetic field equations

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1992
We show that there are varieties of somewhat different loop soliton lattices when we specify an integration path in No Integrability Aesthetic Field Theory. These are illustrated using two dimensional computer maps.

Nutrient Uptake and Efficiencies of Orange-Fleshed Sweet Potato (Ipomoea batatas L.) Varieties under Different Rates of Nitrogen and Phosphorus Fertilizers

open access: yesInternational Journal of Agronomy, 2023
Sweet potatoes serve as a staple food and animal feed in Africa and serve as a source of raw materials for the food, feed, pharmaceutical, cosmetic, chemical, and energy industries. The yield of orange-fleshed sweet potatoes is increased when nitrogen (N)

Environmentally stable common bean genotypes for production in different agro-ecological zones of Tanzania

open access: yesHeliyon, 2021
Genotype by environment interaction (GxE) complicates the process of selecting genotypes suitable for quantitative traits like seed yield in beans, hence slows down the development and release of varieties by breeding programs. GxE study on seed yield in

The Subquasivariety Lattice of a Discriminator Variety

open access: yesAdvances in Mathematics, 2001
The quaterny discriminator on a set \(M\) is the mapping \(d:M^4\to M\) defined by \(d(x,y,z,w):=z\) if \(x=y\) and \(d(x,y,z,w):=w\) otherwise. A variety is called a discriminator variety if it is generated by a class \({\mathbf K}\) of algebras of the same type such that there exists a term representing the quaternary discriminator on every algebra ...

Comparison of Triply Periodic Minimal Surface Energy Absorbers Under Uniaxial Compressive Loading

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates LCD 3D printed Triply Periodic Minimal Surface (TPMS) structures as mechanical energy absorbers. By comparing various base designs and layered combinations under uniaxial compression, it identifies that a Diamond‐Gyroid sandwich structure offers superior performance.
