Abstract Emerging flexible optoelectronics requires a new type of protective material that is not only hard but also flexible. Organic–inorganic (O–I) hybrid materials have been used as cover window to increase wear resistance and polymer‐like flexibility. However, the hardness O–I much lower than metals ceramics due low intrinsic organic matrix limited volume fraction inorganic reinforcement. Herein, nanocomposite combining an with continuous ordered 3D nanoshell additional reinforcement...
Mechanochromic smart membranes capable of optical modulation have great potential in windows, artificial skins, and camouflage. However, the realization high-contrast based on light scattering activated at a low strain remains challenging. Here, we present strategy for designing mechanochromic by introducing Young's modulus mismatch between two interdigitated polydimethylsiloxane phases with weak interfaces periodic three-dimensional (3D) structure. The refractive index-matched nanocomposite...
We investigated the correlation between urine VOC metabolites and airway function in children exposed to anthropogenic volatile organic compounds (VOCs), notable pollutants impacting respiratory health.
The urinary levels of volatile organic compound (VOC) metabolites provide individual exposure compared to data obtained by measuring these compounds in ambient air. We aimed investigate the association between personal concentrations VOC and symptoms atopic dermatitis schoolchildren.Nine were analyzed from urine samples 149 children. Diagnosis was determined using standardized questionnaires. Pediatricians visited schools rated severity SCORing Atopic Dermatitis (SCORAD) all...
Advancement in energy storage technologies has enabled the emergence of new applications, such as grid-scale and domestic electric vehicles (EVs). Despite advances, loss during operation is one major challenges improving efficiency lifetime systems. Reconfigurable allows dynamic rearrangement unit cells to reduce voltage variations therefore increase efficiency, but introduction switching circuit increases upfront cost Therefore, determining granularity reconfiguration that achieves high at...
In this study, polypropylene glycol (PPG) and isophorone diisocyanate (IPDI) with molecular weights (Mws) ranging from 8000 to 18,000 were used as starting materials synthesize silylated polyurethanes (SLPUs) according alkoxysilanes. FT-IR, GPC, DSC analyze composition structure of the synthesized SLPU. Shore A-type, C-type hardness testers, UTM measure hardness, tensile strength, elongation, respectively. It was revealed that mechanical properties viscosity increased Mw PPG increased....
Acute bronchiolitis is a common cause of hospitalization during infancy that carries significant morbidity and mortality rates.
Abstract In force-based seismic design, the behavior factor \(q\) (or response modification \(R\) ) is devised to prevent overdesign by reducing design force. Different values of $q$ are available for various structure types. However, masonry fence walls not categorized in current codes. These poor quality due absence proper assurance and maintenance, most those structures inclined. this study, leaning experimentally estimated. We fabricate three wall that inclined with different angles 1.5...
Masonry is a widely used architectural style for its decent characteristics such as high thermal resistivity and durability. However, poor performance under horizontal load, example, earthquake, has aroused public concerns seismic hazard. We implement shaking table tests two types of model, pristine cracked, to investigate the behavior masonry structure well effect crack. Each model equally designed contain one main wall side walls. Only cracked however, an artificial line crack created on...
In this presentation, a coupling approach of Voronoi-cell lattice model (VCLM) and finite element method (FEM) is proposed for simulating the fracture behaviors quasi-brittle solids. By central role Voronoi cell into elastic uniformity solid deformations, introduced to compliment Poisson effect. The Delaunay/Voronoi dual tessellations in mesh construction facilitate compatibility VCLM with FEM. Therefore, effectively simulates both volumetric behaviors. Besides, strategy domain FEM discussed...
