Magnetic‐Field Control of Surface States in CoFe2O4 Thin Films for Nitrate Electroreduction to Ammonia

open access: yesAdvanced Functional Materials, EarlyView.
Magnetic‐field‐assisted CVD of heterometallic single‐source precursors modulates thin‐film surface electronic structure and interfacial charge transfer. Field‐grown (Cobalt ferrite‐1T)CF‐1T films exhibit stabilized electronic states, lower kinetic barriers, and markedly enhanced nitrate‐to‐ammonia electrocatalysis versus (Cobalt ferrite‐0T) CF‐0T ...

Blood Biomarkers and Surface‐Enhanced Raman Spectroscopy for Gout: A Comprehensive Review

open access: yesAdvanced Functional Materials, EarlyView.
Schematic illustrating gout disease progression from asymptomatic hyperuricemia to chronic tophaceous disease, highlighting the limitations of conventional imaging and biochemical diagnostics and the potential of engineered SERS platforms for ultrasensitive blood‐based detection of urate‐related biomarkers across disease stages, with the color gradient

Bounding families of ruled surfaces

open access: yes, 1996
First published in Proceedings of the American Mathematical Society in Volume 124, Number 10, October 1996, published by the American MathematicalIn this paper we provide a sharp bound for the dimension of a family of ruled surfaces of degree d in P3 K ...

Trace Sulfur‐Doping Boosts NiCo Heterostructured Catalyst for Selective Glycerol‐to‐Formic Acid Electroreforming

open access: yesAdvanced Functional Materials, EarlyView.
A sulfur‐doped Ni–Co heterostructured catalyst is rationally designed to regulate interfacial electronic and adsorption properties for selective glycerol electrooxidation. The synergistic Ni–Co active sites promote hydroxide activation and glycerol adsorption, enabling efficient formic acid production and durable hydrogen generation under continuous ...

General position of points on a rational ruled surface [PDF]

open access: yesBeiträge zur Algebra und Geometrie / Contributions to Algebra and Geometry, 2017
There are several different definitions for the notion of points in general position in \(\mathbb{P}^2\), some of which, due to the authors, are finalized to very ampleness criteria for rank 2 vector bundles [\textit{A. Alzati} and \textit{A. Tortora}, Rev. Mat. Complut. 28, No. 3, 623--654 (2015; Zbl 1330.14070)].

Steering Oxygen Activation Pathways via Redox Dual‐Defects in 2D Hydrated WO3 for High‐Yield Singlet Oxygen Evolution

open access: yesAdvanced Functional Materials, EarlyView.
Redox dual‐defects (Cs substitution and O vacancies) in 2D hydrated WO3 steer O2 activation toward selective singlet oxygen evolution. WO‐CO achieves 8.6–15.8 times higher 1O2 production than single‐defect or pristine catalysts, enabling efficient pollutant mineralization via a pathway‐selective photocatalytic mechanism.

Tropical M\"obius strips and ruled surfaces

open access: yes, 2023
We consider the enumeration of tropical curves in M\"obius strips for two different lattice structures and relate them to the enumeration of curves in two rational ruled surfaces over a complex elliptic curve.

Is It Real Type‐II or S‐Scheme? A Three‐Phase Diagnostic Protocol for Identifying Potentially Mislabeled Heterojunction Photocatalysts

open access: yesAdvanced Functional Materials, EarlyView.
Diagnostic analysis via the heterojunction validation funnel. The funnel illustrates the hierarchical stratification of 30 reported Type‐II systems based on the three‐phase, seven‐step diagnostic framework. Complete validation through all phases is achieved by only 3.3% of systems, while 96.7% lack full mechanistic validation, revealing a pervasive ...

Rational curves and ruled orders on surfaces

open access: yesJournal of Algebra, 2015
We study ruled orders. These arise naturally in the Mori program for orders on projective surfaces and morally speaking are orders on a ruled surface ramified on a bisection and possibly some fibres. We describe fibres of a ruled order and show they are in some sense rational.
