Tin telluride (SnTe) ultrathin films were deposited electrochemically on polycrystalline and monocrystalline gold substrates using the electrochemical atomic layer epitaxy (ECALE) method. The electrochemical behaviors of Sn and Te were studied systematically by means of cyclic voltammetry. Cyclic voltammetry curves for Sn displayed a broad peak in the region between -0.15 V and -0.35 V, which was related to the under-potential deposition (UPD), while the curves for Te displayed a peak at 0.3 V for Te UPD. X-ray pho [...]

Background: Wound management is an important field in medical care, as annually, millions of wounds require treatment worldwide. Soy protein is highly biocompatible, easily processed, and a relatively cheap natural polymer, which can be used for wound dressing applications. Methods: In this study, solvent cast soy protein films, plasticized by glycerol and cross-linked by glyoxal, were thermally treated and their mechanical properties were evaluated as a function of various processing parameters. Samples were then [...]

Microsphere super-resolutions, which are beyond the Abbe classical limit, are described. The conversion of evanescent waves to propagating waves, are analyzed by using the geometry of the microsphere. In microsphere experiments a nanojet is produced near the focal plane where its width is smaller than the Abbe limit and this width remains unchanged in the axial direction for some wavelengths. The interference between evanescent waves converted to propagating waves and the nanojet leads to increase in light intensit [...]

In the past few years, there have been many attempts to commercialize Polymer Dispersed Liquid Crystal (PDLC) for Rear Projection Screen (RPS) in electrically switchable films and glass products. This application is based on the exceptional image quality of PDLC at a wide viewing angle. However, due to the high price of conventional switchable PDLC privacy glass, the integration of RPS in PDLC failed to attract large multimedia and entertainment markets. An obvious solution to this problem is the independent develo [...]

Technical lignins from the biorefinery, pulp, and paper industries are largely underutilized, even though this aromatic and randomly structured biopolymer could be an interesting raw material for advanced applications in addition to bulk daily goods. Recently, colloidal lignin particles (CLPs) have gained much of the research interests due to the attractive multi-functional properties of the biopolymer. Utilization of lignin in nanoparticulate morphology resolves most of the drawbacks when using lignin (heterogenei [...]

Following mental or physical exertion, patients with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) experience Post-Exertional Malaise (PEM). Although self-report questions represent less expensive and invasive procedures to assess PEM, variability in the wording of the symptom can cause reliability and validity problems. If different PEM measures are used in studies, this could create difficulties in replicating findings, identifying biomarkers, and determining effective treatments for patients. The o [...]

Generalized Anxiety Disorder (GAD) is a prevalent mental health condition and the GAD-7 is widely used as a screening tool and measure of GAD severity. However, research has yielded conflicting findings regarding the factor structure of the instrument, with some studies supporting a unidimensional interpretation while others suggest a two-factor solution. These inconsistencies highlight the importance of validating the GAD-7 across diverse populations. This study aimed to assess the psychometric properties and fact [...]

Regenerating injured nerves is difficult because they have little spontaneous regeneration potential. Advances in tissue engineering and regenerative medicine have emphasized the possibility of biomaterial-based methods for nerve healing. Natural protein-based biomaterials have benefits over synthetic ones, such as biocompatibility, non-immunogenicity, and biodegradability. Silk fibroin, generated from mulberry and non-mulberry silkworms, is especially promising because of its abundance, simplicity of processing in [...]

The implementation of modern technologies has transformed connectivity, information-sharing, and education, significantly influencing students' academic journeys. New technologies offer advantages and disadvantages, particularly impacting young students and leading to changes in habits and behaviors. While technology can improve learning efficiency through personalized approaches, excessive screen time can negatively affect communication and academic performance. Studies recommend limited screen time for children t [...]
