In our study, three different silane coupling agents with various functional groups, (y-aminopropyl) triethoxysilane (KH550), γ-(2,3-epoxypropoxy) propytrimethoxysilane (KH560) and trimethoxyoctadecylsilane (TMOS) were added into the SiO2/epoxy composites respectively, and their effects on the rheological and thermome…
Nanotechnology is an emerging/enabling technology and of utmost importance. Two main approaches are used in nanotechnology. In the bottom-up approach, materials and devices are built from molecular components that assemble themselves chemically by principles of molecular recognition. In the top-down approach, nano-obj…
With the advent of lead-free soldering electronic packaging industry, there are growing concerns regarding the problems of voids in lead-free solder joints. Many researchers are eager to understand the growth, evolution and control factors of bubbles. Due to the restrictions in test conditions imposed by high temperat…
A quantum-information analogue of the transistor has been unveiled by two independent groups in Germany and the US.
Recently, it was demonstrated that electrospinning can produce superfine fiber ranging from micrometer to nanometer using an electric field force. In the electrospinning process, a strong electric field is applied between polymer solution contained in a syringe with a capillary tip and grounded collector. When the ele…

Defects could be inevitably generated during the growth or the artificial operation of graphene. The existence of structure defects could be influence to excellent properties of graphene. Non-equilibrium molecular dynamics (NEMD) simulations was used to investigate the thermal conductivity of graphene with single vaca…
This specification deals with flat-rolled electrical steels for magnetic applications. These steels are composed principally of iron with relatively small amounts of alloying elements such as silicon and aluminum. The magnetic properties of the material shall be specified. Electrical steels are normally provided with…
Electromagnetic isolation is a critical issue to the performance of radio frequency system in package (RF SIP). This paper proposes a novel structure to measure the electromagnetic (EM) isolation property and to test the shield efficiency of a metal cap. The 3-dimensional structure contains 5 antenna chips assembled i…
This specification covers high-strength low-alloy structural steel plate used for tubular structures and poles. This steel has atmospheric corrosion resistance so it can be used bare or unpainted for many applications. The materials shall be made by fine grain practice, normal furnishing in the as-rolled condition, an…
This specification covers three grades of zirconium and zirconium alloy forgings. The forgings shall be formed with conventional forging equipment normally found in primary ferrous and nonferrous metal plants. The forgings are furnished in three grades as Grade R60702, Grade R60702, and Grade R60705. Forgings shall be…
Scope 1.1 These test methods cover the procedures for characterizing thermoplastic fabrics (for example polyester, polyamide, polypropylene, and so forth) used in prefabricated roofing and waterproofing membranes. 1.2 Procedures appear in the following o
Significance and Use 5.1 This practice is intended solely for the evaluation of metallic-coated, painted metallic-coated, and painted nonmetallic-coated materials used for the manufacture of cold formed framing members. 5.2 Correlation and extrapolation
Membrane AssemblyMolecularly crowded, polyelectrolyte/ribonucleotide-enriched coacervate droplets are transformed into membrane-bounded subdivided vesicles using a polyoxometalatemediated surface-templating procedur e.As S. Mann and co-workers report on page 1830, this transition results in reconstruction of the coace…
A simple electroless deposition method of fabricating silver nanosheets which is a promising replacement for a high-temperature lead-rich solder used for electronics has been reported. This substrate free deposition method can solve the surface coating problem of the nanostructured silver. By controlling the depositio…
The effect of nano-Bi particles on the growth of intermetallic compound (IMC) between Sn-3.0Ag-0.5Cu-xBi (x=0.0, 0.8, 1.5, 2.5, 3.5, and 4.5 wt.%) solder and Cu substrate during aging process at temperatures of 120, 150, and 190°C has been investigated in this study. Scanning electron microscopy (SEM) was used to obse…
The recently completed European SOFC-Life project aimed to understand in detail the major continuous degradation effects in solid oxide fuel cells, and develop models using new 2D and 3D techniques to predict single degradation phenomena and their combined effect on cells and single repeating units. The researchers fo…
This specification covers requirements and test methods for materials, dimensions and tolerances, pipe stiffness, crush resistance, impact resistance, hydrostatic burst resistance, and solvent cement for poly(vinyl chloride) plastic drain, waste, and vent pipe and fittings. The pipe and fittings covered are suitable f…
Through silicon via (TSV) technology has been widely applied in CMOS image sensors (CIS). This paper reports the wetting behavior of polymer liquid in the TSV insulation process by spin coating.
