Transparent conductive oxides (TCOs) are used in solar cells not only to extract photogenerated carriers but also to allow sunlight to reach the photoactive material. Therefore, controlling the electrical and optical pro...

ObjectiveThis study aimed to investigate the current degree of skin photoaging in young Asian women and to explore the intervention effects of non-ablative bipolar radiofrequency (RF) combined with ablative fractional CO...

The word “Laser” is an acronym for “Light Amplification by Stimulated Emission of Radiation”. Recent advances in laser technology have brought a kind of revolution in dentistry. The purpose of this article is to ...

Modern integrated photonic platforms should combine low-loss guiding, spectral flexibility, high light confinement, and close packing of optical components. One of the prominent platforms represents a one-dimensional pho...

Introduction. The most commonly diagnosed cancer group in humans is cancers of the skin. One pre‑invasive form of squamous cell carcinoma is Bowen's disease. It manifests in the form of single or multiple lesions, whi...

In the model of effective masses and rectangular potentials obtained self-consistent solution of Poisson and Schrödinger equations for different concentrations of electrons. It has been calculated spectral parameters an...

"We study the properties of a soliton crystal, a bound state of several optical pulses that propagate with a fixed temporal separation through the optical fibres of the proposed approach for generation of optical frequen...

Proton beam therapy is a globe preserving treatment method of choroidal melanoma. It is considered to be less harmful for the tissues around the tumour but the complications such as radiation retinopathy and neuropathy o...

Semiconductor nanowires have been used in a variety of passive and active optoelectronic devices including waveguides, photodetectors, solar cells, light-emitting diodes (LEDs), lasers, sensors, and optical ant...

Green laser irradiation successfully activated self-healing processes in epoxy-acid networks modified with low amounts of gold nanoparticles (NPs). A bio-based polymer matrix, obtained by crosslinking epoxidized soybean ...

Two different approaches are used to produce conducting polymer nano-objects. One is a “top-down” approach which involves laser ablation of conducting polymer films using laser light interference patterns (direct las...

Abstract High-harmonic generation and ultrafast electron coherent control are central goals in modern strong-field physics. However, the problem of producing and manipulating electron-matter-wave pulses at zeptosecond ti...

Los mecanismos de transporte de radiación ionizante en presencia de campos magnéticos pueden ser descritos medianteformulaciones basadas en la aplicación de la ecuación principal de Boltzmann. Sin embargo, cuando el ...

El láser es por definición un dispositivo que genera y amplifica luz valiéndose de la emisión estimulada (Light Ampllfication by Stlmulated Emission of Radiation). Los elementos comunes a estos dispositivos son: el ...

En este trabajo se han estudiado varios de los diferentes procesos que tienen lugar durante el calentamiento y la fusión de superficies de aceros al carbono producidos por irradiación con luz infrarroja coherente. En p...

It has been recognized for some time that the spontaneous emission by atoms is not necessarily a fixed and immutable property of the coupling between matter and space, but that it can be controlled by modification of the...
