The Effect of Curing Temperature on the Morphology and Electro-Optical Properties of a Flexible UV-Cured Polymer Dispersed Liquid Crystal (PDLC)

Received: 11 October 2020;  Published: 08 December 2020;  doi: 10.21926/rpm.2004023

Abstract

In this work, the experimental data on flexible PDLC films at the industrial scale and the effect of cure temperature (Tc) on the morphology and electro-optical properties of a UV-cured PDLC system via polymer-induced phase separation (PIPS) method were studied. Under constant UV radiation intebsity and thickness, the morphological parameters such as dimension, number density, and volume fraction of the phase-separated liquid crystal droplets as well as the optical transmissions and switching voltages as a function [...]

Research Progress in Enhancing Proton Conductivity of Sulfonated Aromatic Polymers with ZIFs for Fuel Cell Applications

Received: 22 June 2024;  Published: 04 November 2024;  doi: 10.21926/rpm.2404025

Abstract

The escalating global temperatures and their adverse effects underscore the growing imperative for the widespread adoption of clean fuels, notably hydrogen. Proton Exchange Membrane Fuel Cells (PEMFC) emerge as a pivotal green energy technology, facilitating electricity and water generation. The optimization of PEMFC efficiency hinges on the judicious selection and fabrication of polymer membranes. Within innovative materials, Zeolitic Imidazolate Frameworks (ZIFs) represent a novel subclass within the expansive fa [...]

Celiac Disease and Associated Extraintestinal Manifestations, with Special Reference to Neurological Disorders

Received: 13 July 2020;  Published: 30 October 2020;  doi: 10.21926/obm.neurobiol.2004074

Abstract

Celiac disease (CD), also known as gluten-sensitive enteropathy and nontropical sprue, is one of the most important entities of the wide spectrum of gluten-related disorders (GRDs). It is well known that neurological manifestations can be present either at the onset of CD, or appear during the development of the pathology, and the neurologic findings can show a profound difference. Clinical features show significant variation, ranging from typical manifestations of gastrointestinal involvement to several extraintes [...]

Individual Radiosensitivity in Lung Cancer Patients Assessed by G0 and Three Color Fluorescence in Situ Hybridization

Received: 27 July 2018;  Published: 26 June 2019;  doi: 10.21926/obm.genet.1902082

Abstract

Background: It is well known that radiosensitivity varies substantially from individual to individual. This may influence the tumor response and also cause side effects in normal tissues following the radiotherapy treatment for cancers. Therefore, we aimed to analyze the sensitivity of a lung cancer cohort to see whether patients display similar radiosensitivity distribution as compared to healthy individuals. Methods: Blood samples of healthy individuals (n = 244) and a small group of lung cancer patients (n= 38) [...]

Wind-Stress Variations from Deep to Shallow Water during Hurricanes for Air-Sea-Land Interaction Applications

Received: 27 December 2021;  Published: 14 February 2022;  doi: 10.21926/aeer.2201006

Abstract

In September 2020 Hurricane Sally impacted two National Data Buoy Center (www.ndbc.noaa.gov) buoys near its track: 42040 in the deep water and 42012 in the shallow. Using pertinent air-sea interaction formulas from the literature, analyses of these buoy data indicate that, under fully rough airflow and wind sea conditions, U* = a Hs2 /Tp3 + b, here U* is the friction velocity, Hs is the significant wave height, and Tp is the peak wave period. It is found that a = 28 and b = 0.12 for the deep water environment, a = [...]

Electrodermal Correlates of Hypnosis: Current Developments

Received: 07 February 2020;  Published: 01 April 2020;  doi: 10.21926/obm.icm.2002017

Abstract

Hypnosis has proven to be an effective treatment in disorders that affect the autonomic nervous system (ANS). However, the studies investigating the nature of its effect on the ANS have reported contradictory results. Measurement of electrodermal activity (EDA) is an objective way to assess the activity of the sympathetic branch of the ANS. We aim to elucidate the effects of hypnosis on EDA. Here, we report the results of two studies, both investigating the psychophysiological effects of hypnosis.In the first exper [...]

Nutritional Health and Bioflavonoids

Received: 23 March 2022;  Published: 21 July 2022;  doi: 10.21926/rpn.2203017

Abstract

Flavonoids are phytochemicals (polyphenols) of plant origin. They can trap free oxygen radicals generated by mitochondria and other electronic transport chains, thereby inhibiting inflammatory and carcinogenic changes in vivo and in vitro. Why the body requires these compounds for the well-being of the organism and the maintenance of human health remains unclear. However, a deficit of flavonoids could lead to molecular malfunctions in cells, organelles, and macromolecules. This manuscript describes the occurrence a [...]

Wave Propagation and Scattering due to Debonding in CFRP Strengthened Reinforced Concrete Beams

Received: 28 May 2020;  Published: 27 August 2020;  doi: 10.21926/rpm.2003020

Abstract

Carbon fibre reinforced polymer (CFRP) systems as sheets or plates are commonly used to strengthen and retrofit damaged reinforced concrete beams. In general, the bond between the FRP element and concrete defines the effectiveness of the externally bonded FRP materials. In most cases, the interface bonding behaviour is usually tested via static loading conditions. In this paper, the bonding is verified under dynamic conditions. Wave propagation is modelled in delaminated CFRP strengthened reinforced concrete beam. [...]

Molecular Basis of Allogeneic Pluripotent Stem Cell Treatment of a Patient with Sporadic ALS

Received: 21 August 2020;  Published: 29 March 2021;  doi: 10.21926/obm.geriatr.2101164

Abstract

There are no curative strategies for ALS, and as a result the alternative therapies are gaining ground, in particular the stem cell-based therapies which hold a promising future. Here we describe an ALS patient, who by choice, received allogeneic human cord-blood derived multipotent stem cells (MSC) intravenously and intrathecally. This is the first snapshot of pre-and post-stem cell transplantation in an ALS patient through transcriptomic, epigenomic, and proteomic follow-up elucidating the effect of stem cells in [...]

Theoretical Modelling of Liquid Crystal Electro-Optical Material Display Elements to Achieve Optimal Low Power Consumption Ship Stealth

Received: 29 December 2020;  Published: 14 May 2021;  doi: 10.21926/rpm.2102019

Abstract

Advanced optical stealth techniques are of growing importance in the role of manned and unmanned aircraft or ship platforms. We consider here the concept of using passive reflective display elements rather than high power active light projection to achieve a low observable camouflaged ship platform. This paper presents practical consideration towards minimal radiated power user-driven requirements using adaptive liquid crystal electro-optical methods. Optical reflectivity for a multi-layer liquid crystal cell struc [...]
