Advanced Engineering Materials, Volume 27, Issue 6, March 2025.ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Laser Powder Bed Fusion of Alumina: Effects of Scanning Strategies on External and Internal Defects
Advanced Engineering Materials, EarlyView.This study investigates how scanning strategies affect pure alumina in laser powder bed fusion. Linear 45° scanning yields uniform surfaces but high porosity, while the island‐concentric strategy provides higher density with through‐holes favorable for infiltration. Findings highlight pathways toward optimizing defect‐free alumina parts.

We study the sequence space X p q obtained by using the domain of q-analogue of the Cesaro matrix C ( q ) = ( c i j q ) defined by c i j q = { q j − 1 [ i ] q ( 1 ≤ j ≤ i ) , 0 ( j > i ) , where the notation [ i ] q has the usual meaning.

A new paranormed sequence space defined by Catalan conservative matrix
Mathematical methods in the applied sciences, 2020In this study, by using the Catalan conservative matrix, we define a new paranormed sequence space ℓ(C˜,p) and show that the space ℓ(C˜,p) is linearly isomorphic to ℓ(p). Also, we determine dual spaces and the Schauder basis of the resulting space.

Single-molecule structural and kinetic studies across sequence space
ScienceAt the core of molecular biology lies the intricate interplay between sequence, structure, and function. Single-molecule techniques provide in-depth dynamic insights into structure and function, but laborious assays impede functional screening of large ...

AbstractThis paper studies the metric structure of the space Hr of absolutely summable sequences of real numbers with at most r nonzero terms. Hr is complete, and is located and nowhere dense in the space of all absolutely summable sequences. Totally bounded and compact subspaces of Hr are characterized, and large classes of located, totally bounded ...

Convergence in Sequence Spaces
Proceedings of the Edinburgh Mathematical Society, 1958In a perfect sequence space α, on which a norm is defined, we can consider three types of convergence, namely projective convergence, strong projective convergence and distance convergence. In the space σ∞, when distance is defined in the usual way, the last two types of convergence coincide and are distinct from projective convergence ((2), p.
