Supra-Quantum Dot Assemblies to Maximize Color-Based Multiplexed Fluorescence Detection with a Smartphone Camera

, 2023
Photoluminescence (PL) imaging and bioanalysis with smartphone-based devices are of growing interest for point-of-care/point-of-need diagnostics. Strategies for maximizing sensitivity have been explored in this context, but color multiplexing has been ...

SUPRA HOMEOMORPHISM IN SUPRA TOPOLOGICAL ORDERED SPACES [PDF]

Facta Universitatis, Series: Mathematics and Informatics, 2017
The purpose of this paper is to introduce the concepts of x-supra continuous (open, closed, homeomorphism) maps in supra topological ordered spaces for x ∈ {I,D,B}. We study the relationship among these types with the help of examples and investigate the equivalent conditions for each concept.

UTILIZING SUPRA α-OPEN SETS TO GENERATE NEW TYPES OF SUPRA COMPACT AND SUPRA LINDELÖF SPACES [PDF]

Facta Universitatis, Series: Mathematics and Informatics, 2017
The purpose of this article is to introduce the concepts of supra α-compact(supra α-Lindel¨of) spaces, almost supra α-compact (almost supra α-Lindel¨of) spaces and mildly supra α-compact (mildly supra α-Lindel¨of) spaces in supra topological spaces utilizing a notion of supra α-open sets.

Supra R-homeomorphism in supra topological ordered spaces

International Journal of Algebra and Statistics, 2017
In this work, The notions of supra R-open sets and and increasing (decreasing, balancing) sets are utilized to initiate some ordered maps namely, x- supra R-continuous, x-supra R-open, x-supra R-closed and x-supra R homeomorphism maps, for x ∈ {I,D,B}. The equivalent conditions for each concept are given and the relationships among them are illustrated

Sub-50 nm perovskite-type tantalum-based oxynitride single crystals with enhanced photoactivity for water splitting

Nature Communications, 2023
A long-standing trade-off exists between improving crystallinity and minimizing particle size in the synthesis of perovskite-type transition-metal oxynitride photocatalysts via the thermal nitridation of commonly used metal oxide and carbonate precursors.
