Synthesis of Microwave Circuits Based on Metamaterials Using Aggressive Space Mapping Algorithms
En l'enginyeria de microones, alguns dels principals reptes son la reduccio de la mida dels circuits i la flexibilitat de disseny. Aquests son aspectes clau dels dispositius de comunicacions i, com a resultat, s'han fet molts esforcos en aquesta direccio. Un clar exemple son les anomenades linies de transmissio basade…
AlPOs Synthetic Factor Analysis Based on Maximum Weight and Minimum Redundancy Feature Selection
The relationship between synthetic factors and the resulting structures is critical for rational synthesis of zeolites and related microporous materials. In this paper, we develop a new feature selection method for synthetic factor analysis of (6,12)-ring-containing microporous aluminophosphates (AlPOs). The proposed…

The element composition, surface inspection, structural, and morphological features of the products are depend on the concentration of zinc ni…
Preferential Behavior on Donating Atoms of an Ambidentate Ligand 2-Methylisothiazol-3(2H)-one in Its Metal Complexes
Five metal complexes of 2-methylisothiazol-3(2H)-one (MIO), [Co(III)(NH3)5(MIO)](3+), [Ru(II)(NH3)5(MIO)](2+), [Ru(III)(NH3)5(MIO)](3+), [Pt(II)Cl3(MIO)](-), and trans-[U(VI)O2(NO3)2(MIO)2], were synthesized, and their structures were determined by single-crystal X-ray crystallography. MIO is an ambidentate ligand and…
A Study on Generating Electricity by Using Exhaust Waste Heat in a Diesel Engine
Internal combustion engines are widely used in our day. Internal combustion engines first transform fuel energy into heat energy. Afterwards, approximately 30% of this heat energy is transformed into mechanical energy. Approximately 5% of the heat energy is expelled through friction and radiation, 30% through cooling…
Porous Copper Fabricated through Powder Metallurgy Route Using NaCl Space Holder
Porous Copper (porous Cu) with varying porosities was prepared using sodium chloride (NaCl) particles as space holder through powder metallurgy route. Pre-alloyed copper that was used as a feedstock material were mixed with the varying proportion (0%, 20%, 40% and 60% of volume fraction) of laboratory grade NaCl prior…
The Study on Eri-Silk Degumming Process Optimization and its Properties
Study the influence of eri-silk degumming process for degumming results of 2709 alkaline protease; combined with the orthogonal experimental analysis of high degumming rate and breaking strength of the best eri-silk degumming process, and then compare the optimized extracted eri-silk with mulberry silk, virgin silk, c…
Crosslinking Density of Silk Fibroin – Rice Starch Hydrogels Modified with Trisodium Trimetaphosphate
Silk fibroin (SF) and rice starch (RS) are both biopolymers being non-toxic, biocompatible and biodegradable which can be utilized as hydrogels. The aim of this study was to prepare the SF–RS hydrogels modified with trisodium trimetaphosphate (STMP) and determine its crosslinking density for providing a guideline for…
Research on the Design of an Optical Information Storage Sensing System Using a Diffractive Optical Element
This paper introduces a compact optical information storage sensing system. Applications of this system include longitudinal surface plasmon resonance detection of gold nanorods with a single femtosecond laser in three-dimensional space as well as data storage. A diffractive optical element (DOE) is applied in the sys…
Formation and Evolution of Liquid Pools Entrapped within Primary Particles of In Situ Mg2Si/AM60B Composite with Fine-Grains during Partial Remelting
The formation mechanism and evolution of liquid pools entrapped within solid grains have been investigated during partial remelting of in-situ Mg2Si/AM60B composite with fine-grains during partial remelting. The results indicate that the merging of dendrite arms during the initial stage of partial remelting is the mai…
Tensile and Compression Behavior of Woven Glass/Epoxy Nano Composites Based on Spraying Methodology
Nanocomposites have been utilized increasingly because of their high strength, stiffness, toughness, and through-thickness properties. The incorporation of carbon nanofibers with a high aspect ratio and extremely large surface area into glass/epoxy polymer composites improve their tensile and compression properties si…
