Journal: :Liquid Crystals 2022

In this paper, we have investigated the dielectric properties of nematic liquid crystals (NLCs) by measuring resonant frequencies inverted microstrip lines (IMSLs) NLC being substrate material at microwave frequency band. The designed IMSL devices consist a cavity for mixture between line and ground plane. anisotropy values NLCs were determined observing change when strength external electric f...

This paper deals with the imaging problem for one-stationary bistatic synthetic aperture radar (BiSAR) with highsquint, large-baseline configuration. In this bistatic configuration, accurate focusing of BiSAR data is a difficult issue due to the relatively large range cell migration (RCM), severe range-azimuth coupling, and inherent azimuthgeometric variance. To circumvent these issues, an enha...

We consider the interaction between nematic liquid crystals (NLCs) and polymer substrates. Such substrates can interact with NLCs, exhibiting a phenomenon known as director gliding: the preferred orientation of the NLC molecules at the interface changes on time scales that are slow relative to the elastic relaxation time scale of the NLC. We present two models for gliding, inspired by experimen...

Although solid lipid nanoparticles (SLNs) and nanostructured carriers (NLCs) have been successfully used as drug delivery systems for about 30 years, the usage of these food-grade nanovehicles nutraceuticals or bioactive compounds has been, relatively speaking, scarcely investigated. With fast-increasing interest in incorporation a wide range bioactives food formulations, well health awareness ...

In the first part of this paper the topic of networked learning is approached from the perspective of workers in the knowledge economy who engage in lifelong learning in communities of practice and in formal education. Distributed communities of practice (DCoP) in the knowledge economy are similar in function to networked learning communities (NLCs) in formal education with a stronger focus on ...

Flexoelectricity is a coupling between orientational deformation and electric polarization. We present a direct method for measuring the flexoelectric coefficients of nematic liquid crystals (NLCs) via the electric current produced by periodic mechanical flexing of the NLC's bounding surfaces. This method is suitable for measuring the response of bent-core liquid crystals, which are expected to...

Sea buckthorn (SB) (Elaeagnus rhamnoides (L.) A. Nelson) is rich in flavonoids, phenolic compounds, anthocyanins, carotenoids, and phytosterol. Its phytochemicals exhibit various biological activities, such as antioxidant, immunomodulatory anti-carcinogenic activities. SB also helps prevent the development of wrinkles protects skin’s surface from UV rays. The purpose present study was to develo...

As communist regimes throughout Central and Eastern Europe have fallen one by one under the weight of economic failure and popular discontent, the task of transforming these countries into stable and vibrant liberal democratic societies has commanded the attention of many Western governments and international organizations. Given the rapid and extremely destabilizing deterioration in the levels...

More research on networked learning communities (NLCs) and the causal mechanism among effects of NLCs are needed. To better understand impacts influential factors, this study intended to discover how teachers’ participation in affects their beliefs behaviors professional further influence receptivity change. Adopting a survey design, we collected 226 valid questionnaires from pilot schools join...

Objective: To develop coenzyme Q10 (co-Q10) nanostructured lipid carriers (NLCs) using stearic acid (SA) and various liquid lipids with different lipophilicity as well highlights the use of in silico studies for predicting elucidating interaction drug-lipid used carries NLCs, at molecular level.
 Methods: The co-Q10 NLCs were prepared SA solid oleic (OA), isopropyl myristate (IPM), palmita...
