Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

open access: yesAdvanced Materials, Volume 37, Issue 48, December 3, 2025.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

Experimental Study of Suppressing the Thermoacoustic Instabilities in a Rijke Tube Using Microsecond Discharge Plasma

open access: yesAerospace, 2022
Thermoacoustic instabilities occur when heat release is coupled with pressure fluctuation, which may cause performance degradation of the combustor and serious structural damage.

Non-linear simulations of combustion instabilities with a quasi-1D Navier-Stokes code

open access: yes, 2010
As lean premixed combustion systems are more susceptible to combustion instabilities than non-premixed systems, there is an increasing demand for improved numerical design tools that can predict the occurrence of combustion instabilities with high ...

Sodium‐based, geopolymer foamed composites reinforced with phosphate mine waste particulates and hemp/basalt fibers

open access: yesJournal of the American Ceramic Society, Volume 108, Issue 12, December 2025.
Abstract This study investigated the mechanical, microstructural, and thermal properties of Na‐based geopolymer foams (GPFs) reinforced with varying amounts of two types of reinforcements: raw phosphate mine waste rock (PMWR) as a particulate filler, and natural (hemp) or synthetic (basalt) fibers.

Limit-Cycle Properties of a Rijke Tube [PDF]

open access: yes, 2003
Thermoacoustic instability appears when unsteady heat release is favourably coupled with acoustic pressure perturbations. The important technical applications involving thermoacoustics are combustion instability in rocket motors and low-pollutant lean ...

Optimized Continuous Thermosonication for Sustainable Pasteurization of Orange and Dried Black Lime Juices: Techno‐Functional, Physicochemical, and Microbial Assessment

open access: yesFood Science &Nutrition, Volume 13, Issue 11, November 2025.
The study developed a continuous thermosonication system (CTS) for the sustainable pasteurization of orange and dried black lime juices. CTS reduced energy consumption by 30% compared to traditional pasteurization while preserving physicochemical, sensory, and microbiological quality.

Focused Power Ultrasound Mediated Inferior Perirenal Adipose Tissue Modification Therapy for Essential Hypertension: A Pilot Study

open access: yesThe Journal of Clinical Hypertension, Volume 27, Issue 10, October 2025.
ABSTRACT Perirenal adipose tissue (PRAT) contributes to the maintenance of elevated blood pressure through afferent nerves and serves as an important peripheral, modifiable target for hypertension management. This single‐center, prospective pilot trial assessed the feasibility and safety of a novel focused power ultrasound device for perirenal adipose ...

Suppression Mechanisms of Stratified Jet-in-Crossflow on Thermoacoustic Instability and NOx Emissions in Premixed Combustors

open access: yesApplied Sciences
The premixed combustion of a gas turbine is prone to thermoacoustic oscillation, which affects the safety of combustion systems. This study experimentally investigated the suppression mechanism of a stratified jet-in-crossflow on the thermoacoustic ...

A dissipative time reversal technique for photo-acoustic tomography in a cavity

open access: yes, 2015
We consider the inverse source problem arising in thermo- and photo-acoustic tomography. It consists in reconstructing the initial pressure from the boundary measurements of the acoustic wave.
