An aluminum alloy casting process energy consumption model is created, the model to energy activities as the basic activity unit, description of energy consumption by energy conversion device behavior, to fully reflect the constituent elements of the energy system coordinated through the process energy...

Regular aligned porous waterborne polyurethane (WPU) composites were simply obtained by a directional freeze-drying process in the study. The morphology of the WPU composite can be tailored with different concentration of the WPU dispersion and freezing rate. Very regular aligned pores along the immersion...

Membrane separation technology is one of the most innovative and steadily growing fields across science and engineering. The performance of a membrane is determined by several key properties: high selectivity and permeability; excellent chemical, thermal, and mechanical stability under the process operating...

We propose all-solution processed white quantum dots light emitting devices (WQLEDs) based on CdSe/ZnS Quantum dots(QDs)/polymer hybrid emissive layer which was red, green and blue (RGB) QDs and blue emitting homo-polymer blending. The proposed WQLED showed higher brightness, external current efficiency...

Based on the basic properties of the green material itself, environmental adaptability and feeling of comfort, analyzes that green materials should follow the basic principles, that are the use of good workability, good processing manufacturability, best economy, good aesthetics, non-toxic harmless and...

According to "The vertification regulation of bitumen needle forcemeter for road"(JJG 067-2006), calibration of bitumen needle forcemeter is resolved by measuring indication device and time controller respectively. But this way of calibration can't solve the problem of starting indication device at the...

The major problem in microwave processing is attenuation of microwave heating source. This work is investigation by simulation on the microwave energy attenuation into the long and thick parts with curve-shaped geometry. Physical properties of final products to be manufactured, in particular the mechanical...

The enrichment of denitrifying phosphate accumulating organisms (DNPAOs) is the prerequisite for the denitrifying phosphate removal process. This study investigated the effect of nitrate concentration on the enrichment of DNPAOs was studied with batch experiments. The Sequencing Batch Reactor (SBR) was...

Nipa sap is one of the efficient feedstocks for ethanol production. Response surface methodology with the central composite design was used to design and optimize the sap preparation. The main factors were initial pH (4.5 - 6.5), warming temperature (30 - 60°C) and time (5 - 30 min). The effects of the...

W-beam guardrails are the most widely used road safety barriers worldwide. They are used for protecting vehicle occupants on dangerous areas of roadways. The ability of W-beam guardrails to absorb some of the crash energy reduces the risk of injury for vehicle occupants and limits deformation of impacting...

High shear wet granulation is widely used in the pharmaceutical industry, however it is still difficult to predict the results of granulation and explain the relevant results. The paper reviews the three key processes in high shear granulation: wetting and nucleation, consolidation and growth, and breakage...

We have been synthesized MoO3 nanobelts by thermal chemical vapor deposition. The growth products will be studied by field emission scanning electron microscope (FESEM), X-ray photoemission (XPS), Raman Spectroscopy, X-rays diffraction (XRD). SEM images showed the belts-like nanostructures. XPS and Raman...

Composite material is fourth largest aviation materials after the aluminum, steel, titanium and has been widely used in aviation. Defects and damages is inevitable in the process of its production and manufacturing, that seriously hazards the aviation security. Tap testing is the simplest and the most...

The main purpose of this paper is using modification of nanoparticle layers to increasing the hydrophilic surfaces and enhancing the evaporation behaviors in stainless steel plate. When the products being made, use three different kind of fluids, acetone, ethanol and water to testing the benefit for...

The amelogenins (Am) constitute about 90% of the enamel matrix proteins and play a critical role in enamel biomineralization. This study aimed to express and characterize recombinant human amelogenin (rAm) protein in the prokaryotic expression system in quantities sufficient for structural and functional...

A socket is used as a handling tool after matching with a ratchet wrench. Its main function is to handle all kinds of screws and nuts and other fastening parts, but sockets are often lost after falling down on the ground or rolling over before and after their use. This research employs TRIZ to improve...

The heavy logistics, discrete operation floor, volume work in process, high-intensity operation and informal operational standards are taken as the production problems of digital caliper assembly in the G company. According to the problems mentioned above, the improvement scheme of caliper assembly line...

Passive Optical Network is designed such that it meets the requirements of NG-PON. According to FSAN, the Time and Wave Length Division Multiplexing (TWDM) is chosen as the best solution to implement NG-PON. EDFA amplifier is used in the system to compensate the effects of degraded signal in both the...
