Polymeric particles are strong candidates for designing artificial materials capable of emulating the complex twisting-based functionality observed in biological systems. In this Letter, we provide the first detailed investigation of the swelling behavior of bipolar polymer liquid crystalline microparticles. Deswelling from the spherical bipolar configuration causes the microparticles to contract anisotropically and twist in the process, resulting in a twisted spindle-shaped structure. We propose a model to describe the observed spiral patterns and twisting behavior.

We investigate the discrete diffraction phenomenon in a Polymer-Liquid Crystal-Polymer Slices (POLICRYPS) overlaying a random distribution of gold nanoparticles (AuNPs, plasmonic elements). We study t...
In this work, the theoretical model of non-uniform diffraction structures' holographic formation in liquid crystal-photopolymer (LC-PPM) composite materials with a dye-sensitizer is developed. The mod...
Using a surface force apparatus, a cholesteric liquid crystal was confined between two crossed cylindrical surfaces that induced strong planar anchoring and normal alignment of the chiral helix. The f...
In recent years, ionic liquid-based surfactants have drawn more and more attention. As a new promising brand of surfactants, ionic liquid-based surfactants have their unique properties and superior ag...
Two functionalized carbohelicenes, one of which was also available in its two enantiomeric pure forms, were oriented in stretched polystyrene (PS) in CDCl and a recently introduced chiral thermores...
The EASYX™ Liquid Embolic is a new injectable, precipitating polymeric agent for the obliteration of vascular spaces through direct puncture or catheter access performed under X-ray guid...
Fiberoptic bronchoscope (FOB) intubation is one of multiple techniques used for endotracheal intubation. It is characterized by the ease of visualization of the different parts of the airw...
The study is designed to evaluate the effectiveness of liquid crystal contact thermography in detecting pathological changes in female breasts compared to standard diagnostic methods.
The study was a multicentre, observational, cross-sectional, open and monitored trial involving 274 females who were subject to an examination using liquid crystal contact thermography dev...
Our aims is to document the possible effect of cryo- preservation at the meiotic spindle and mitochondrial levels.
The use of a quartz crystal microbalance for measuring weights and forces in the micro- to nanogram range. It is used to study the chemical and mechanical properties of thin layers, such as polymer coatings and lipid membranes; and interactions between molecues.
Polymers of N-SUBSTITUTED GLYCINES containing chiral centers at the a-position of their side chains. These oligomers lack HYDROGEN BONDING donors, preventing formation of the usual intrachain hydrogen bonds but can form helices driven by the steric influence of chiral side chains.
Strongly cationic polymer that binds to certain proteins; used as a marker in immunology, to precipitate and purify enzymes and lipids. Synonyms: aziridine polymer; Epamine; Epomine; ethylenimine polymer; Montrek; PEI; Polymin(e).
Techniques which study entities using their topological, geometric, or geographic properties and include the dimension of time in the analysis.

Biological therapy involves the use of living organisms, substances derived from living organisms, or laboratory-produced versions of such substances to treat disease. Some biological therapies for cancer use vaccines or bacteria to stimulate the body&rs...
Depression is a serious mental health condition, where sad feelings carry on for weeks or months and interfere with your life. The symptoms include feeling unhappy most of the time (but may feel a little better in the evenings), loosing interest in lif...
