Closed ideals of Lie algebras

open access: yesHiroshima Mathematical Journal, 1994
Let \(L\) be a Lie algebra and \(I\) be an ideal of \(L\). Define the closure of \(I\) in \(L\) as \(cl(I) = \{x \in L : \langle y \rangle^L \cap I \neq 0\) for all \(0 \neq y \in \langle x \rangle^L\}\), where \(\langle x \rangle^L\) is the ideal generated by \(x\).

Biomimetic Iridescent Skin: Robust Prototissues Spontaneously Assembled from Photonic Protocells

open access: yesAdvanced Functional Materials, EarlyView.
Uniform nanoparticles are induced to form arrays (photonic crystals) in the cores of biopolymer capsules, endowing these ‘protocells’ with structural color. These protocells are then assembled into large self‐standing objects, i.e., prototissues, with robust mechanical properties as well as iridescent optical properties.

MOFs and COFs in Electronics: Bridging the Gap between Intrinsic Properties and Measured Performance

open access: yesAdvanced Functional Materials, EarlyView.
Metal‐organic frameworks (MOFs) and covalent organic frameworks (COFs) hold promise for advanced electronics. However, discrepancies in reported electrical conductivities highlight the importance of measurement methodologies. This review explores intrinsic charge transport mechanisms and extrinsic factors influencing performance, and critically ...

Deliberation, Competition, or Practice?

open access: yesNordicom Review, 2013
Several studies have found that political online debates do not to live up to deliberative standards of discussion. Even so, these debates may have democratic value.

Rapid Sintering of Porous Organic Polymer Powders Into Mechanically Strong Monoliths for Efficient CO2 Capture

open access: yesAdvanced Functional Materials, EarlyView.
Spark plasma sintering enables rapid processing of porous organic polymer (POP) from fine powders to a freestanding and mechanically robust monolith. The sintering process retains the CO2 adsorption capacity and CO2/N2 selectivity, making the monolith more suitable as a solid sorbent for practical carbon capture applications.

A Termite‐Inspired Alternative to Cement

open access: yesAdvanced Functional Materials, EarlyView.
A termite‐inspired composite of clay, cellulose, and lignin forms a dense fibrous network with concrete‐like strength (32 MPa) and superior elasticity, processed at ambient temperature. Abstract Clay combined with organic materials is used by termites as a strong and durable construction material for their mounds with minimal environmental impact. Here,

NORMS OVER FUZZY LIE ALGEBRA

open access: yesJournal of New Theory, 2017
Abstaract−In this paper we introduce the concept of fuzzy Lie ideal and anti fuzzy Lie ideal by using a t-norm T and a t-conorm C, respectively. Next we introduce the concept of quotient fuzzy Lie ideal with respect to t-norm T. We investigate some their

Golden‐Ratio–Guided Aperiodic Architected Metamaterials with Simultaneously Enhanced Strength and Toughness

open access: yesAdvanced Functional Materials, EarlyView.
Guided by the golden ratio, a class of aperiodic architected metamaterials is introduced to address the intrinsic trade‐off between strength and toughness. By unifying local geometric heterogeneity with global order, the golden‐ratio‐guided aperiodic architecture promotes spatial delocalization of damage tolerence regions, leading to more tortuous ...
