Due to the precise and continuous regulation of phase, holographic encryption based on metasurfaces and liquid crystals (LCs) has been proposed to encrypt the information by manipulating the wavelength, polarization, etc...

Photonic metamaterials combined with liquid crystals (LCs) for tunability is a great niche for building miniature devices with high performance such as fast flat tunable lenses, tunable filters, and waveplates. Sub-wavel...

Dielectric metasurfaces hold an exceptional potential for the next generation of tunable optical systems that find applications in sensing, ranging, and imaging. Here, we introduce and demonstrate magnetic field tuning o...

The therapeutic benefit of phosphorothioate oligodeoxynucleotides (PS-ODN) containing immune stimulatory sequences has been demonstrated in animal models of cancer and infection. Several tools are available for the deter...

Abstract We show that electron crystals compete closely with non-Abelian fractional Chern insulators in the half-filled second moiré band of twisted bilayer MoTe2. Depending on the twist angle and microscopic model, the...

Chiral photonic-band structure provides technical benefits in the form of a self-assembled helical structure and further functional wavelength tunability that exploits helical deformation according to pitch changes. The ...

1-(acyl/aroyl)-3-(substituted)thioureas are exciting structures in the fields of organic synthesis, material sciences, and biomedical research. Of particular significance is the fact that acyl thiourea derivatives have b...

Wet ball milling was used to exfoliate MoS2. The aim of the study was to examine how the surface energy of all the individual materials affected the formation of the nanosheets. Two types of milling balls were selected: ...

Liquid crystals can exhibit structural orientational order. The creation of a mixture with the addition of chiral molecules to the nematic liquid crystal induces helical twisting, the axis of which is directed perpendicu...

For the Czochralski method with liquid encapsulation of the melt and an additional heater immersed in the flux, the dependence of the temperature gradient G near the crystallization front in GaAs crystals on the heater p...

Phase equilibria in the quasi-ternary systems HgS–Ga2S3–Bi(Sb)2S3  were studied by physico-chemical analysis methods on 177 alloys that were synthesized by direct single-temperature method. Phase diagrams of the qu...

Circularly polarized light emitting active materials are of great interest, and the convenient tuning of the circularly polarized luminescence (CPL) remains a significant challenge. Integrating fluorescent materials into...

Akçal Au-Ag mineralization is located in one of the most important metallogenic provinces in Tethys Orogenic Belt, Biga Peninsula. In the study area, widespread argillic alteration is observed and mined in previous year...

En este trabajo se estudió experimentalmente la influencia sobre la estabilidad de espumas en aerosol de concentrados con aspecto nacarado y, en algunos casos, además con características líquida cristalinas. Tanto el...

En este trabajo se evaluaron dos sistemas líquido-cristalinos liotrópicos para la liberación sostenida de cafeína en ensayos in vitro: uno formado por una mezcla de Poloxamer 407 y agua, que presenta la fase cúbic...

Con la finalidad de obtener emulsiones aceite-agua de aplicación en el campo farmacéutico y cosmético, se desarrolla una técnica original de estabilización mediante el empleo de montmorillonitas naturales y montmori...

Los copolímeros en bloques están formados por macromoléculas constituidas por bloques poliméricos dispuestos en una secuencia lineal. Entre los copolímeros en bloques con aplicaciones farmacéuticas se destacan los ...

In this research, birefringent emulsions stabilized with Steareth-2 and Steareth-21 were studied. Some authors attributed to them a liquid-crystalline structure, although the microphotographs presented by them as an ev...

The purpose of the present investigation was to evaluate 6-O-palmitoyl ascorbic acid (ASC16) and 6-O-lauril ascorbic acid (ASC12) for their capacity to promote permeation of Ibuprofen (IBU) through hairless mouse skin in...

Existe evidencia experimental y mediciones de campo que indican que la presencia de la fase hielo en una nube de tormenta es fundamental para el desarrollo de la estructura eléctrica observada en el interior de la misma...

Spherical crystallization (SC) is a promising alternative for improiving micromeritic properties and dissolution rate of active pharmaceutical ingredients. In the present work spherical agglomerates of carvedilol (CAR) w...
