RECEIVED DATE (to be automatically inserted after your manuscript is accepted if required according to the journal that you are submitting your paper to) Although ambient processing is the key to low-cost organic solar cell production, high-vacuum thermal evaporation of LiF is often a limiting step, motivating the exploration of solution processing of LiF as an alternative electrode interlayer....

Rates of isolation of yeasts from blood cultures were significantly enhanced by venting vacuum blood culture bottles in studies of both stimulated and patients' blood cultures; however, the time interval to detection of positivity of yeasts in the clinical studies was significantly (P less than 0.01) shorter in a vented bottle with biphasic brain heart infusion medium than in a vented bottle wi...

CFRP structures are often exposed to humid environment resulting in water absorption and causing property degradation. Water swelling its effect on tensile, compressive, flexural properties were investigated according ASTM standards. Fracture modes evaluated by analyzing micrographs of fracture areas. The specimens cut from twill wave composite plates fabricated using a vacuum infusion techniqu...

The quality of Liquid Composite Molding (LCM) manufactured components is strictly related to the fibrous preform impregnation. As Darcy’s law suggests, resin flow influenced by pressure gradient, geometrical features reinforcement, and viscosity. former two parameters are dictated requirements component other constraints; therefore, they hardly modifiable during process. Resin preheating increa...

The research objective was investigate the effect of alkali treatment on thermal stability, interfacial shear strength, mechanical properties and waterabsorption in composite honey pineapple fiber (HPF). HPF not given treated by soaking a mixture 6% wt sodium hydroxide. Mixing between Unsaturated Polyester (UPRs) Microcrystalline Cellulose (MCC) applied Taguchi test with 5% MCC, 250 RPm, 40 oC ...

Purpose: The purpose of the paper is to manufacture the polymer matrix composites using vacuum assisted resin infusion molding. Design/methodology/approach: Electrical heating resistances are used for heating of table. The temperature control is achieved by means of acquiring temperatures using thermocouples located beneath the table surface. VARIM table is divided into eight regions. Each regi...

Wafer level packaging could reduce the cost of MEMS based sensors through simplified processing and inexpensive components. A novel vacuum tight seal referred to as the wedge seal method is proposed in this paper. The seal consists of a silicon wedge forced into a pliable material (typically a metal) that is attached to the component wafer. The wedge-seal addresses some of the requirements of m...

In this work, we investigate the electrical surface conductivity that is temporarily induced in SiO2 by exposure to monochromatic vacuum-ultraviolet synchrotron radiation for modification of plasma charging. Special preprocessed test structures were exposed to controlled fluxes of monochromatic synchrotron radiation in the range of 500–3000 Å ~approx. 4–25 eV!, the energy band of most plasma va...

Colloidal quantum dot light-emitting diodes (QLEDs) are recognized as promising candidates for next generation displays. QLEDs can be fabricated by low-cost solution processing except for the metal electrodes, which, in general, are deposited by costly vacuum evaporation. To be fully compatible with the low-cost solution process, we herein demonstrate vacuum-free and solvent-free fabrication of...
