Cluster‐assembled materials: Ordered structures with advanced properties

open access: yesInfoMat, 2021
Cluster‐assembled materials (CAMs) present delicate structures and tailored properties, which have gained extensive interest in recent years. Due to the noncovalent linkage and size of sub‐1 nm, clusters present polymer‐like solution behaviors distinct ...

The structure of the Mitchell order – II [PDF]

open access: yesAnnals of Pure and Applied Logic, 2015
We isolate here a wide class of well founded orders called tame orders and show that each such order of cardinality at most $κ$ can be realized as the Mitchell order on a measurable cardinal $κ$, from a consistency assumption weaker than $o(κ) = κ^+$.

Self-ordered nanospike porous alumina fabricated under a new regime by an anodizing process in alkaline media

open access: yesScientific Reports, 2021
High-aspect ratio ordered nanomaterial arrays exhibit several unique physicochemical and optical properties. Porous anodic aluminum oxide (AAO) is one of the most typical ordered porous structures and can be easily fabricated by applying an ...

Fabrication of porous carbon structures for biological fuel cells [PDF]

open access: yes, 2010
PhDBiofuel cells demand three-dimensional, “high” surface area electrodes with “high” electrical conductivity and structural integrity. The aim of this project is to design and fabricate porous carbon structures as electrodes for enzyme and microbe

Ordered/Disordered Structures of Water at Solid/Liquid Interfaces

open access: yesCrystals, 2023
Experiments and theory have revealed versatile possible phases for adsorbed and confined water on two-dimensional solid surfaces, which are closely related to the aspects of various phenomena in physics, chemistry, biology, and tribology. In this review,

On the Structure of Order Domains

open access: yesFinite Fields and Their Applications, 2002
The idea of an order function originated with the second author [\textit{R. Pellikaan}, J. Stat. Plann. Inference 94, No.~2, 287-301 (2001; Zbl 0981.94055)] as a way to consider one-point Goppa codes using ring theory, without using algebraic geometry. An order function generalizes the order of pole of a rational function along a prime divisor.

Cryo-ET detects bundled triple helices but not ladders in meiotic budding yeast

open access: yesPLoS ONE, 2022
In meiosis, cells undergo two sequential rounds of cell division, termed meiosis I and meiosis II. Textbook models of the meiosis I substage called pachytene show that nuclei have conspicuous 100-nm-wide, ladder-like synaptonemal complexes and ordered ...

The quasiparticle band structures of ordered NixPt1-x

open access: yesHeliyon, 2018
The quasiparticle band structures of the ordered L12 and L10 phases of NixPt1-x (x = 0.25, 0.5, and 0.75) have been calculated and compared to the band structures obtained using density functional theory.
