A PRESENTATION OF DESARGUES’ THEOREM APPLYING THE DESCRIPTIVE GEOMETRY RULES

Journal of Industrial Design and Engineering Graphics, 2006
This paper presents Desargues’ theorem in two ways: – the solution by incidence and succession; - the solution by the application of the descriptive geometry rules.

Influence of light incidence angle and polarization on the refractive index sensitivity of tightly-packed ellipsoidal gold nanoparticle layers

Sensing and Bio-Sensing Research
The effect of excitation angle and polarization on the bulk refractive index sensitivity (RIS) of hexagonally-arranged gold nanoparticles is studied through numerical simulations and experiments.

CO2 Reduction on Copper‐Nitrogen‐Doped Carbon Catalysts Tuned by Pulsed Potential Electrolysis: Effect of Pulse Potential

Advanced Functional Materials, EarlyView.
This study demonstrates that pulsed potential electrolysis significantly improves CO2 reduction performance on copper‐nitrogen doped carbon electrodes. The formation of cationic copper sites and metallic clusters as a function of applied intermittent potential leads to notable selectivity changes compared to potentiostatic reduction.

On a paucity result in Incidence Geometry

, 2022
We obtain some asymptotic formulae (with power savings in their error terms) for the number of quadruples in the Cartesian product of an arbitrary set $A \subset \mathbf{R}$ and for the number of quintuplets in $A\times A$ for any subset $A$ of the prime field $\mathbf{F}_p$.

Colloidal Opaline Composites as Throughput‐Scalable, Fully Transparent, and Color‐Tunable Radiative Cooling Exterior Films for Outdoor Photovoltaics

Advanced Functional Materials, EarlyView.
Particular thermal metamaterials are widely used as daytime radiative coolers merely by embedding thermally emissive nanoparticles (NPs) in liquid resins to form scalable, yet highly efficient cooling films in a cost‐effective way. However, randomly dispersed NPs, prevalently used thus far, cause strong scattering, limiting NP content and cooling ...

Self‐Assembled Membranes for High Ion Selectivity and Proton Blocking in Electrochemical Applications

Advanced Functional Materials, EarlyView.
Phase‐separated alkyl poly(vinylimidazolium) membranes exhibit exceptional ionic conductivity, counter‐ion selectivity, and proton‐blocking ability by forming stable micro/macrophase‐separated domains. This design overcomes the conductivity–selectivity trade‐off in conventional ion‐exchange membranes (IEMs), offering a new paradigm for high‐performance
