Geometry‐Encoded Actuation as a Structural Interaction Layer in Origami Robots

Advanced Science, EarlyView.
We present geometry‐encoded actuation (GEA), a design framework that integrates multistable origami with liquid crystal elastomer actuators to encode environmental interactions into autonomous structural responses. GEA enables programmable shape transformation without continuous sensing or complex control, achieving robust adaptive manipulation and ...

Magneto‐NIR‐II‐Programmed Cascade Nanozymes Unlocking Blood–Brain Barrier Translocation and Autophagic Resistance in Glioblastoma

Advanced Science, EarlyView.
Magneto‐NIR‐II‐programmed NFSH nanozymes integrate magnetic blood–brain barrier (BBB) translocation, CD44 targeting, multimodal imaging, and cascade catalytic therapy for glioblastoma. Alternating magnetic fields and NIR‐II irradiation amplify ferroptosis, release H2S, suppress autophagic and mitophagic repair, and reshape the immune microenvironment ...

PYROMETRY USING PHOTOTHERMAL EFFECT

Proceeding of International Heat Transfer Conference 8, 1986
The radiation leaving a solid surface results from both emission and reflection. Only the first contribution depends on the temperature. An important and still unsolved problem in pyrometry is to measure the emission separately and quantitatively. We propose a new temperature measurement technique based on the photothermal effect for which the emission

Thermal effects in photothermal spectroscopy and photothermal imaging

Journal of Applied Physics, 1983
The effect of thermal parameters on photothermal spectroscopy and photothermal imaging for certain types of spatially heterogeneous samples has been studied. Results have been obtained for both photoacoustic and photothermal deflection modes of detection. Specific attention has been paid to optical saturation in samples whose properties exhibit gradual

Photothermal effect of Au nanoparticles and photothermal inactivation to saccharomycetes cell

Optik, 2020
Abstract Au nanoparticles (Au NPs) absorb light energy and convert it to thermal energy that transfers to environment. The temperature variation of Au NP and environment as well as photothermal conversion efficiency of Au NP are problems concerned by researchers.

Effect of nucleants in photothermally assisted crystallization

Photochemical & Photobiological Sciences, 2017
Laser-induced crystallization is emerging as a promising technique to crystallize biomolecules like amino acids and proteins. The use of external materials as nucleants and novel seeding methods open new paths for protein crystallization. We report here the results of experiments that explore the effect of nucleants on laser-based crystallization of ...

Photothermal effect in Semiconductors

Physical Review, 1961
When a sample of semiconducting material is illuminated, pairs of excess carriers are generated which diffuse through the material according to the density gradients established. Each pair carries an energy approximately equal to the band gap of the material.

Nanosecond Photothermal Effects in Plasmonic Nanostructures

ACS Nano, 2012
Photothermal effects in plasmonic nanostructures have great potentials in applications for photothermal cancer therapy, optical storage, thermo-photovoltaics, etc. However, the transient temperature behavior of a nanoscale material system during an ultrafast photothermal process has rarely been accurately investigated.

Photothermal effects of laser tissue soldering

Physics in Medicine and Biology, 1999
Low-strength anastomoses and thermal damage of tissue are major concerns in laser tissue welding techniques where laser energy is used to induce thermal changes in the molecular structure of the tissues being joined, hence allowing them to bond together.
