Comparative Analysis of Al2O3/Water–TiO2/Chlorophyll Hybrid Nanofluids in a Photovoltaic–Thermal Solar Water Heating System

Energy Science &Engineering, EarlyView.
TiO2/chlorophyll bio‐hybrid nanofluid achieved the highest PVT performance, increasing thermal efficiency to 38.74% and overall efficiency to 51.35%, compared with 35.96% and 48.45% for Al2O3/water and 27.77% and 40.18% for water. The results demonstrate the potential of bio‐hybrid nanofluids for high‐efficiency solar thermal energy conversion ...

Representation and Weak Convergence of Stochastic Integrals with Fractional Integrator Processes [PDF]

This paper considers the asymptotic distribution of the covariance of a nonstationary fractionally integrated process with the stationary increments of another such process - possibly, itself.

Effect of Microchannel Geometry on Nanoparticle Deposition in Nanofluid Flow

International Journal for Numerical Methods in Fluids, EarlyView.
This study numerically analyzed nanoparticle deposition in microchannels with varying geometries. Deposition per unit area decreases significantly with increasing bend angle (28.612 to 8.941 between 30° and 120°) and bend radius (11.922 to 4.769 between 0.2 and 0.4 mm). Acute bends and small radii enhance centrifugal forces and flow separation, leading

Moderate Deviation Principle for Two-Time-Scale Caputo FSDEs Driven by Fractional Brownian Motion

Fractal and Fractional
This work investigates the moderate deviation principle for a class of two-time-scale Caputo fractional stochastic differential equations. The driving noise of the slow variable is fractional Brownian motion with Hurst index H∈(12,1).

Dyson's Brownian motions, intertwining and interlacing [PDF]

, 2007
A reflected Brownian motion in the Gelfand-Tsetlin cone is used to construct Dyson's process of non-colliding Brownian motions. The key step of the construction is to consider two interlaced families of Brownian paths with paths belonging to the second ...

Innovative Method for Evaluating the Optical Properties of Liquid–Liquid Phase Separations Using Laser Scanning Microscopic Spectroscopy

Microscopy Research and Technique, EarlyView.
The LLPS phenomenon in the optoDroplet method can be discerned through the use of fluorescent molecular spectroscopy, which enabled the distinction between droplet formation and gelation. ABSTRACT Liquid–liquid phase separation (LLPS) plays a central role in intracellular compartmentalization and gene regulation.

Mass Spectrometry‐Based Extracellular Vesicle Proteomics for Biomarker Discovery

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Extracellular vesicle (EV) proteomics has emerged as a powerful platform for decoding intercellular communication and advancing biomarker discovery across human diseases. EVs carry proteins that reflect their cells of origin, offering a minimally invasive window into physiological and pathological processes.
