Coefficient of thermal expansion (CTE) mismatch between an underfill encapsulant material and integrated circuit chips mounted on a substrate is the major reason for device failure in fan-out wafer-level packaging (FOWLP) assembly. In this paper, variety moldable polymer composite systems with evenly dispersed dielectric nanoparticles or microparticles minimal cure shrinkage FOWLP assemblies have been investigated. Most importantly, low CTE 6.6 ppm/°C high glass transition temperature (T...
The standard methods of calculating the fluid friction factor, Colebrook–White and Haaland equations, require iterative solution an implicit, transcendental function which entails high computational costs for large-scale piping networks while introducing as much 15% error. This study applies group method data handling to development artificial neural network optimized by multi-objective genetic algorithms find explicit polynomial model factor. We developed a relatively simple factor that...
The phenol photocatalytic degradation was investigated using heterogeneous catalyst Ag-doped ZnO nanowires under UV irradiation. Ag-ZnO were immobilized on borosilicate glass via a simple hydrothermal technique. Preliminary photodegradation studies performed with at various concentrations of (10 - 60 mg/L) undiluted pH. After determination the optimal initial concentration (30 mg/L), additional parameters including pH and light intensity to optimize for large-scale application. experimental...
Micro-phase change materials (micro-PCMs) are proposed to increase the thermal conductivity and energy storage capacity of a heat transfer fluid (HTF). In this work, we have selected dimethyl terephthalate (DMT) be used as PCM for performance enhancement synthetic oil in temperature range approximately 100 170 °C. Silicon dioxide (SiO2) was microencapsulant, because its desirable properties containment material, including stability. The SiO2-coated DMT micro-PCM characterized determine...
This study describes the development and characterization of novel high-temperature thermal storage media, based on inclusion transition metal chlorides in potassium–sodium chloride eutectic system, (K–Na)Cl (melting temperature 657 °C, latent heat 278 J/g). At melting (K–Na)Cl, infrared (IR) radiation can play a major role overall transfer process—90% spectral blackbody falls range 2–13 μm. The authors propose small amounts (less than 0.2 wt.%) IR-active to increase radiative absorption...
There is substantial potential to increase the operating temperatures of concentrating solar power (CSP) plants, thereby increasing Carnot efficiency. Coupled with viable thermal energy storage (TES) strategies, this would bring us closer achieving goals U.S. Department Energy Sunshot Initiative. Current TES media employ molten inorganic salts (namely, nitrate salts) for storage, but they are limited in application lower temperatures: generally, below 600°C. While sufficient parabolic trough...
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is transmitted human-to-human via aerosols and air-borne droplets. Therefore, capturing destroying viruses from indoor premises are essential to reduce the probability of human exposure virus transmission. While heating, ventilation, air conditioning (HVAC) systems help in reducing viral load, a targeted approach required effectively remove SARS-CoV-2 address concerns. The present study demonstrates efficient trapping destruction...

Recently, rectennas have drawn attention as an attractive option to harvest radiative thermal energy from the sun and terrestrial sources. In order achieve potential high conversion efficiencies by this technology, matching conditions between incident electromagnetic wavelength rectenna characteristic length must be satisfied. Therefore, a selective emitter is key element in efficiency rectennas. Photonic structures were designed for emission using transfer matrix method genetic algorithm...
