We have used grazing incidence x-ray scattering to study the structure of a smectic-C* liquid crystal (LC) at the buried LC-glass interface in liquid crystal films. This measurement is done in reflection mode through the glass substrate, which consis

Chemical attachment of the thiol-derivatized DNA monolayers on arsenic terminated GaAs (001) has been achieved. The sulfur-As-based covalent bonds of the thiolated oligonucleotids on the arsenic terminated GaAs (001) were observed using x-ray photoel

We studied the structural transformation of diamond-like amorphous carbon (a-C) films into ultrahard carbon nanocomposites via postannealing to 600 °C using transmission electron microscopy, x-ray reflectivity, and small-angle scattering. Film densi

We have studied the in‐plane (parallel to the magnetic field) alignment of 8CB mixed with FeCo nanoparticles covered with different funtionalization compounds. The functionalization compounds are Polyethelene glycol (PEG (3000)), hydroxyl succinimi

We have used Grazing Incidence X-ray Diffraction to study the structure of a liquid crystal (LC) at the buried LC-glass interface in micrometer size LC films. This measurement is done in reflection mode through the glass substrate, which consists of

The interaction of nanometer particles with organic materials is important because of their increased use in many applications and their potential use in biosystems. We found that liquid crystals respond to nanometer particles differently depending o

The behavior of smectic-A liquid crystals with magnetic particles has not been very well characterized. The authors have studied the interaction of a smectic-A liquid crystal with magnetic nanoparticles. They concentrate on the effect of the particle

We have studied the depth dependence and temperature behavior of the ordering of smectic-A films close to the smectic A-nematic transition, deposited on grated glass. X-ray grazing incidence geometry in reflection mode through the glass substrate was

We have added magnetic nanoparticles with a different surface termination (functionalization) to smectic A 8CB liquid crystals and studied their effects on the order of the liquid crystal. This is done by looking at the liquid crystals both with pola

Magnetic nanoparticles (MNPs) have found increased applicability in drug delivery, cancer treatment, and immunoassays. There is a need for an improved understanding of how MNPs interact with living cell membranes in applied magnetic fields to use the
