A barrier film is a fundamental component of the fast growing organic electronic device industry that is necessary to sustain long‐term stability. The barrier film prevents the permeation of environmental moisture and oxygen into the organic electronic device. Superior barrier property is the most crucial characteristic of a barrier film, in addition to a high refractive index. A high‐refractive‐index barrier film has the potential to reduce the refractive‐index mismatch between a device and a protective film, consequently, reducing the energy costs by increasing the light output. In this work, six epoxy and phenoxy resin composite compositions are synthesized separately, each with a different cross‐linker. POL‐TE1/PET and POL‐HD1/PET films show enhanced refractive indexes of 1.726 (at 750 nm) and 1.721 (at 500 nm), allowing only 71.7% and 70.4% permeation, respectively, compared to those of POL/PET, while exhibiting more than 80% transparency and excellent properties. The films are fabricated using a straightforward process, from a solution, at low temperature and under atmospheric conditions, using an applicator and bar coating. 相似文献

We consider the notion ofp, δ-absolute continuity for functions of several variables introduced in [2] and we investigate the validity of some basic properties
that are shared by absolutely continuous functions in the sense of Maly. We introduce the classδ−BV

Adductor spasmodic dysphonia (ADSD) adversely affects a speaker's ability to effectively communicate. For many individuals suffering with ADSD, botulinum toxin (Botox) is the chosen treatment to remediate the symptoms. Although Botox's effects on symptom remediation have been examined before, patient perception of improvement post-Botox has been examined less frequently. Further, no studies have addressed the symptomatic changes in older adults that occur after Botox treatment. The Voice Handicap Index (VHI) was used as the instrument to assess older patient's (>65 years) perception of how ADSD impacts certain areas of their life pre- and post-Botox injection. The outcome of the VHI was related to a clinical judgment of voice severity. Participants also completed the Social Readjustment Rating Scale (SRRS) to examine overall stress level, and the outcome of the SRRS was correlated to postinjection VHI scores. Results indicated no significant correlation between VHI scores and voice severity or SRRS ratings. The current study suggests further study of voice outcomes with older adults with ADSD is needed. 相似文献

Current paper involves the one‐pot synthesis of various 1,2‐dihydropyridine and 1,2,3,4‐tetrahydropyrimidine analogues. The antitumor activity of the synthesized compounds has been carried out against various human cancer cell lines, and some of the analogues are found to be potent. 相似文献

Biodegradable polymer nanocomposites, due to their biodegradability and other improved properties possess tremendous scope in the industrial sector. This current article reviews the recent studies carried out over biodegradable polymer nanocomposites that includes preparation, characterization, properties, and applications of nanocomposites based on biodegradable polymers. An orderly introduction of nanocomposites prepared by using various biodegradable aliphatic polyesters and polymers obtained from biomass products has been brought about. A wide range of organic and inorganic nanoparticles was used as additives or fillers to prepare nanocomposites with improved desired properties. Considering vast research on layered silicates/polymer nanocomposites, a special emphasis has been summarized at the end of the review. 相似文献
