Preparation of Cholesteric Polymer Networks with Narrow-Bandwidth Reflection and Memory Effect

open access: yesCrystals, 2023
A polymer network with a memory effect based on a polymer-stabilized narrow-bandwidth cholesteric liquid crystal (CLC) was prepared using the washing-out/refill method.

High performance shape memory polyurethane synthesized with high molecular weight polyol as the soft segment [PDF]

open access: yes, 2012
Shape memory polyurethanes (SMPUs) are typically synthesized using polyols of low molecular weight (MW~2,000 g/mol) as it is believed that the high density of cross-links in these low molecular weight polyols are essential for high mechanical strength ...

The effects of elaboration on recognition memory [PDF]

open access: yesMemory & Cognition, 1980
Two experiments were conducted to examine the effects of elaboration on recognition memory. Subjects were given either simple or complex sentences to learn and were tested for recognition of either an individual target word or the entire sentence. Complex sentences supported better recognition performance only when the test item allowed the subject to ...

ROC analysis of the verbal overshadowing effect: testing the effect of verbalisation on memory sensitivity [PDF]

open access: yes, 2015
This study investigated the role of memory sensitivity versus recognition criterion in the verbal overshadowing effect (VOE). Lineup recognition data was analysed using ROC analysis to separate the effects of verbalisation on memory sensitivity from ...

Determination of Total Mercury in Gold-loaded Carbon by Solid Mercury Analyzer

open access: yesYankuang ceshi, 2016
Gold-loaded carbon has a strong adsorption ability of mercury, which will result in the pollution of the gold extraction process and reduce the absorption of gold by activated carbon.

Brief Overview of Ice Nucleation

open access: yesMolecules, 2021
The nucleation of ice is vital in cloud physics and impacts on a broad range of matters from the cryopreservation of food, tissues, organs, and stem cells to the prevention of icing on aircraft wings, bridge cables, wind turbines, and other structures ...

Subsequent memory effects in schizophrenia [PDF]

open access: yesPsychiatry Research: Neuroimaging, 2014
Differential neural activation at encoding can predict which stimuli will be subsequently remembered or forgotten, and memory deficits are pronounced in schizophrenia. We used event-related functional magnetic resonance imaging (fMRI) to investigate subsequent memory (SM) effects for visual fractals in patients with schizophrenia (n=26) and healthy ...

Thermal-Mechanical Properties of Polyurethane-Clay Shape Memory Polymer Nanocomposites [PDF]

open access: yes, 2010
Shape memory nanocomposites of polyurethane (PU)-clay were fabricated by melt mixing of PU and nano-clay. Based on nano-indentation and microhardness tests, the strength of the nanocomposites increased dramatically as a function of clay content, which is
