Absorption, scattering, and fluorescence are processes that increase with electric field intensity. The most prominent way to enhance electric field intensity is to use localized or propagating surface plasmon polaritons...

Although traditional quantum-confined nanostructures e.g. regular quantum wells or quantum dots have achieved huge success in the field of semiconductor lasers for past decades, these traditional nanostructures are encou...

Silver nanostructures were successfully synthesized through a simple and "green" method using saccharides as reducing and capping agent. Transmission electron microscopy (TEM) and UV-Vis absorption were used to certify t...

Background: Outer membrane vesicles (OMVs) from Gram-negative bacteria are spherical lipid bilayer nanostructures with diameters of 20 to 250 nm. Porphyromonas gingivalis (P. gingivalis), a keystone periodontal pathogen,...

Metasurface holography has aroused immense interest in producing holographic images with high quality, higher-order diffraction-free, and large viewing angles by using a planar artificial sheet consisting of subwavelengt...

The extremely high peak intensity associated with ultrashort pulse width of femtosecond laser allows us to induce nonlinear interaction such as multiphoton absorption and tunneling ionization with materials that are tran...

Three-dimensional (3D) imaging at the nanoscale is a key to understanding of nanomaterials and complex systems. While scanning probe microscopy (SPM) has been the workhorse of nanoscale metrology, its slow scanning speed...

An advanced full-wave time-domain numerical model for reverse saturable absorption (RSA) is presented and verified. Rate equations describing atomic relaxations and excitation dynamics are coupled to the Maxwell equation...

Structural colors generated by optical micro-/nanostructures offer a notable advantage over traditional chemical pigments, including higher purity, greater brightness, resistance to fading, and enhanced environmental fri...

Nonreciprocal thermal radiation can violate Kirchhoff’s law and exhibit different emissivity at symmetric polar angles relative to the normal direction. Realizing a mid-infrared broadband nonreciprocal thermal emitter ...

Fabrication of continuous ultra-thin gold films (

Nano- and micro-oxides are promising materials due to several interesting characteristics such as photocatalytic and antimicrobial role. In this work, zinc oxide nanorods were obtained by microwave-assisted solvothermal ...

A novel and simple self-assembled direct formation of ZnO nanorod (NR) bunches on boron (p-type)-doped crystalline Si (100) substrates has been achieved by the EPD technique. All the nanostructures were formed from a col...
