Device Applications Enabled by Bandgap Engineering Through Quantum Dot Tuning: A Review.

Quantum dots (QDs) are becoming essential materials for future scientific and real-world applications, owing to their interesting and distinct optical and electrical properties compared to their bulk-state counterparts. The ability to tune the bandgap of QDs based on size and composition-a key characteristic-opens up new possibilities for enhancing the performance of various optoelectronic devices. These advances could extend to cutting-edge applications such as ultrawide-band or dual-band photodetectors (PDs), optoelectronic logic gates, neuromorphic devices, and security functions.

Relationship Between Voice Problems and Depression Among American Adults.

Objective: Voice problems have a large impact on quality-of-life and societal participation. It has been previously reported that persons with voice problems have a higher likelihood of depression than those without voice problems. Despite this knowledge, little has changed in clinical practice related to screening for depression or incorporating the presence of depression in treatment planning.

Purpose: The purpose of this study was to compare the prevalence of dysphonia and dysphagia among adults in the United States between 2012 and 2022.

Method: A retrospective and cross-sectional design with national surveys was used. The 2012 and 2022 National Health Interview Surveys were utilized to estimate the number of adults reporting dysphonia and dysphagia in the past 12 months.

One-Pot Synthesis and Characterization of CuCrS/ZnS Core/Shell Quantum Dots as New Blue-Emitting Sources.

In this paper, we introduce a new blue-emitting material, CuCrS/ZnS QDs (CCS QDs). To obtain bright and stable photoluminescent probes, we prepared a core/shell structure; the synthesis was conducted in a one-pot system, using 1-dodecanethiol as a sulfur source and co-ligand. The CCS QDs exhibited a semi-spherical colloidal nanocrystalline shape with an average diameter of 9.

Simply Fabricated Inexpensive Dual-Polymer-Coated Fabry-Perot Interferometer-Based Temperature Sensors with High Sensitivity.

We designed simply fabricated, highly sensitive, and cost-effective dual-polymer-coated Fabry-Perot interferometer (DFPI)-based temperature sensors by employing thermosensitive polymers and non-thermosensitive polymers, as well as different two successive dip-coating techniques (stepwise dip coating and polymer mixture coating). Seven sensors were fabricated using different polymer combinations for performance optimization. The experiments demonstrated that the stepwise dip-coated dual thermosensitive polymer sensors exhibited the highest sensitivity (2142.

Enhancing Temperature Sensitivity of the Fabry-Perot Interferometer Sensor with Optimization of the Coating Thickness of Polystyrene.

The exploration of novel polymers for temperature sensing with high sensitivity has attracted tremendous research interest. Hence, we report a polystyrene-coated optical fiber temperature sensor with high sensitivity. To enhance the temperature sensitivity, flat, thin, smooth, and air bubble-free polystyrene was coated on the edge surface of a single-mode optical fiber, where the coating thickness was varied based on the solution concentration.

Influence of Gold-Silver Rough-Surface Nanoparticles on Plasmonic Light Scattering in Organic Solar Cells.

Department of Chemical and Biological Engineering, Gachon University, Seongnam, Gyeonggi 461-701, Korea Among metallic nanomaterials used as plasmonic structures in organic photovoltaics (OPVs), gold (Au) and silver (Ag) nanoparticles (NPs) have attracted significant attention owing to their remarkable localized surface plasmon resonance optical properties and relatively high scattering efficiency. In this study, we propose rough-surface Au@Ag core-shell NPs (RSAu@Ag NPs) as an advanced plasmonic material to combine the high scattering power of Ag NPs and broad spectral response of Au NPs in the long-wavelength range. We coat an Au nanoflower core with a thin Ag shell to fabricate the RSAu@Ag NPs.

Drug holiday as a prognostic factor of medication-related osteonecrosis of the jaw.

Objectives: To identify post-treatment prognostic factors for medication-related osteonecrosis of the jaw (MRONJ).

Materials And Methods: We evaluated 54 MRONJ patients who visited the Department of Dentistry, Ajou University Hospital, from May 2007 to March 2014. Twenty-one patients were surgically managed with debridement or sequestrectomy and 33 patients were conservatively managed using antibiotics.

Spectral domain optical coherence tomography findings in bilateral peripheral cone dystrophy.

Introduction: To report spectral domain optical coherence (OCT) tomography findings in a case of bilateral peripheral cone dystrophy.

Case Report: A 21-year-old man complained of blurred visual fields on the lateral sides of both eyes. The patient's best-corrected visual acuity was 20/20 in both eyes.

Analysis of spectral domain optical coherence tomography findings in occult macular dystrophy.

Purpose: To describe findings of spectral domain optical coherence tomography (SD-OCT) in the diagnosis of occult macular dystrophy (OMD).

Materials And Methods: Five visually disturbed patients who had shown normal findings in full field electroretinogram (ERG), fundus photography and fluorescein angiography but abnormal findings in multifocal ERG had undergone SD-OCT. The morphologic changes in retina and macular thickness were detected and imaged by SD-OCT.

Citicoline reduces upregulated clusterin following kainic acid injection in the rat retina.

Purpose: To investigate the effects of citicoline on upregulated clusterin and retinal damage induced by kainic acid (KA).

Methods: KA was injected into the vitreous of rats. Effects of systemic citicoline treatments were estimated by measuring the thickness of the various retinal layers, immunoblotting, and immunohistochemical techniques.

The suppressive effect of myeloid Elf-1-like factor (MEF) in osteogenic differentiation.

Myeloid Elf-1 like factor (MEF) is a member of the Ets transcription factor family. Ets family proteins control the expression of genes that are critical for biological processes such as proliferation, differentiation, and cell death. Some of Ets factors are also known to regulate bone development.

Phosphatase and tensin homolog deleted on chromosome 10 (PTEN) reduces vascular endothelial growth factor expression in allergen-induced airway inflammation.

Vascular endothelial growth factor (VEGF) plays a pivotal role in the pathogenesis of bronchial asthma. Phosphatase and tensin homolog deleted on chromosome 10 (PTEN) has been implicated in regulating cell survival signaling through the phosphoinositide 3-kinase (PI3K)/Akt pathway. The key role of PI3K in VEGF-mediated signal transduction is established.

Radiofrequency thermal ablation of primary pleural synovial sarcoma.

Percutaneous radiofrequency (RF) thermal ablation has received attention as an effective minimally invasive approach for the treatment of a variety of neoplasms. However, the therapeutic efficacy of RF thermal ablation on primary pleural synovial sarcoma has not yet been reported. A 76-year-old man with a primary pleural synovial sarcoma who was medically inoperable received RF thermal ablation to achieve local control.

The left end of IS2: a compromise between transpositional activity and an essential promoter function that regulates the transposition pathway.

Cut-and-paste (simple insertion) and replicative transposition pathways are the two classical paradigms by which transposable elements are mobilized. A novel variation of cut and paste, a two-step transposition cycle, has recently been proposed for insertion sequences of the IS3 family. In IS2 this variation involves the formation of a circular, putative transposition intermediate (the minicircle) in the first step.
