Tailoring Chiral Gold Nanorods via Single‐Step Seed‐to‐Au(III) Ratio and Unlocking their Potential in Refractive Index Sensing

Advanced Optical Materials, Volume 13, Issue 34, December 2, 2025.
A single‐step tunable chiral growth of Au NRs with controllable circular dichrosim (CD) response is reported, and the application of narrow CD response for biosensing with superior Figures of Merit (FoM = RIS/linewidth) over conventional extinction‐based approach in sensitivity is demonstrated.

Main Characteristics of Mexico City Local Wind Events during the MILAGRO 2006 Campaign within a Meso‐β Scale Lattice Wind Modeling Approach

International Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013
A characterization of local wind events in Mexico City, which occurred during MILAGRO campaign, was carried out within the framework of a lattice wind modeling approach at a meso‐β scale. Mexico City was modeled as a 2D lattice domain with a given number of identical cells. Local wind conditions at any cell were described by a state variable defined by

Coexistence of weak and strong coupling in a photonic molecule through dissipative coupling to a quantum dot

Nanophotonics, Volume 14, Issue 27, Page 5163-5175, December 2025.
Abstract We study the emission from a molecular photonic cavity formed by two proximal photonic crystal defect cavities containing a small number (<3) of In(Ga)As quantum dots. Under strong excitation, we observe photoluminescence from the bonding and antibonding modes in agreement with ab initio numerical simulations.

Adaptive Control for Nonlinear Systems with Time‐Varying Control Gain

Journal of Control Science and Engineering, Volume 2012, Issue 1, 2012., 2012
We propose a scheme for nonlinear plants with time‐varying control gain and time‐varying plant coefficients, on the basis of a plant model consisting of a Brunovsky‐type model with polynomials as approximators. We develop an adaptive robust control scheme for this plant, under the following assumptions: (i) the plant terms involve time‐varying but ...

Rayleigh′s, Stoneley′s, and Scholte′s Interface Waves in Elastic Models Using a Boundary Element Method

Journal of Applied Mathematics, Volume 2012, Issue 1, 2012., 2012
This work is focused on studying interface waves for three canonical models, that is, interfaces formed by vacuum‐solid, solid‐solid, and liquid‐solid. These interfaces excited by dynamic loads cause the emergence of Rayleigh′s, Stoneley′s, and Scholte′s waves, respectively.

Directional spontaneous emission in photonic crystal slabs

Nanophotonics, Volume 13, Issue 11, Page 1963-1973, May 2024.
Abstract Spontaneous emission is one of the most fundamental out‐of‐equilibrium processes in which an excited quantum emitter relaxes to the ground state due to quantum fluctuations. In this process, a photon is emitted that can interact with other nearby emitters and establish quantum correlations between them, e.g., via super and subradiance effects.
