Advanced Healthcare Materials, EarlyView.ABSTRACT Sutures are crucial for tissue approximation and wound healing. Besides their strength limits requirement, they often fail to effectively address complications like infection and pain. Inspired by natural silk's “core‐sheath” structure, our suture features a wet‐spun core of n zinc‐fortified silk fibroin fibers (RSF‐Zn2+) after drawing with ...

Integrated Visible Light and Oxidant Protection Through Multifunctional Sunscreens
Advanced Healthcare Materials, EarlyView.High‐energy visible radiation (HEVR), although less energetic than UV light, penetrates deeper into the skin and contributes to photoaging, pigmentation disorders, and oxidative stress. The development of new HEVR‐targeted filters, therefore, represents not only a scientific challenge but also a pressing public health and cosmetic industry need.

Radiative Corrections to Decay Processes
Physical Review, 1956Radiative corrections associated with the electromagnetic field have been determined for the decay of a fermion of arbitrary mass into a lighter one with the emission of a single boson or of two other fermions; no special assumptions have been made about the nature of the interaction responsible for the instability.

On the radiative-collision processes
Annales de Physique, 1987During the last fifteen years numerous of work have been devoted to the so-called Radiative-Collision processes. The absorption or emission of a photon during collisions of atoms in the presence of a strong electromagnetic field leads to elementary processes involving a rich variety of collisional processes.

Elementary Radiative Processes
2019Parameters of elementary processes involving photons and atomic particles are evaluated. These processes include photoionization of atoms, and photorecombination of electrons and atomic ions, photodetachment of negative ions, and photorecombination of electrons and atoms, photodissociation of molecules. Photoprocesses involving highly excited atoms are

A solution-processed radiative cooling glass
Science, 2023Passive daytime radiative cooling materials could reduce the energy needed for building cooling up to 60% by reflecting sunlight and emitting long-wave infrared (LWIR) radiation into the cold Universe (~3 kelvin). However, developing passive cooling structures that are both practical to manufacture and apply while also displaying long-term ...

Radiative Processes in Heterostructures
1999In this chapter we discuss the processes of spontaneous photon emission by quasi-equilibrium electron-hole pairs in heterostructures. Such processes are responsible for a variety of physical effects, from luminescence to las-ing. Many important device applications of heterostructures, such as lasers and light-emitting diodes, operate by using radiative

Fluctuations in Radiative Processes
Physica Scripta, 1986The purpose of these two lectures is to present a brief review of theoretical works done at Ecole Normale Superieure in collaboration with Jean Dalibard, Jacques Dupont-Roc and Claude Fabre. The motivation of these works is to try to understand the dynamics of an atomic system coupled to the radiation field and to get some physical insight in radiative

Il Nuovo Cimento A, 1989
Weak as well as pure electromagnetic radiative decays of hyperons are discussed. The radiative decays of excited hyperon states can provide information on the quark wave functions inside the hyperons. The weak (strangeness-changing) decays represent the last low-q2 frontier of weak-interaction physics.
