Composite filaments based on acrylonitrile butadiene styrene (ABS) consisting of cellulose nanocrystal (CNC) were prepared by melt intercalation using a single screw extruder. The effect CNC loading levels (0-4 wt%) the tensile properties and water absorption behavior was investigated in this work. Results indicated that composite exhibited rougher surfaces non-uniform diameters than neat ABS f...

In this study, nanocellulose is isolated from oil palm empty fruit bunches using ultrafine grinding and ultrasonication. Here, nanocellulose, a reinforcing agent, mixed with polyvinyl alcohol sodium alginate, which act as the matrices. Nanocellulose-based fibers are produced via wet spinning method calcium chloride coagulant solvent. The effects of content on morphological, mechanical, in vitro...

Serendipitous measurements of deep internal wave signatures are evident in oscillatory variations around the background descent rates reported by one model Deep Argo float. For 10,045 profiles analyzed here, average root-mean-square vertical velocity variances, , from 1,000 m to seafloor, is 0.0045 s−1, with a 5%–95% range 0.0028–0.0067 s−1. Dominant wavelengths, λz, estimated integrals lagged ...

Growing environmental demands and higher fuel efficiency encourage the use of new light-weight load-bearing materials even for operation under rougher conditions. Consequently, as used in vital components chassis, brake system or exhaust are subjected to thermomechanical fatigue during due variable mechanical thermal loads, it is crucial design engineers CAE analysts understand cyclic behaviour...

The present study is focused on the characterization of fatigue damage features in carbon/epoxy laminates under mode-II loading conditions. To this aim, a sinusoidal cyclic load was applied to End-Notched Flexural (ENF) specimens and behavior investigated. Scanning Electron Microscope (SEM) used identify fracture surface, i.e. fiber imprints, cusps, roller striations. It found that features, su...

The deposition of an additional layer nanoparticles is a widely used method for improving the optical and electrical characteristics semiconductor solar cells (SCs). In this work, films nanocrystals (NC) inorganic perovskites lead halides CsPbI 3 CsPbBr are deposited on surface cell based crystalline silicon (c-Si). It shown that properties such NC in good agreement with c-Si. has been found ab...

Some properties of biodegradable edible films developed from starches acha (Digitalia exilis) and iburu iburua), with glycerol as plasticizer, were evaluated compared. Scanning electron microscope revealed that starch film (ASF) had rougher surface larger size spores. Both showed similar crystallinity pattern made up A-type cereal backbone process induced VH-crystals. FTIR spectroscopy the trac...

Plant leaf surfaces can contain interesting, reproducible spatial patterns that be used for several industrial purposes. In this paper, the main goal was to analyze surface microtexture of Amazon Anacardium occidentale L. using multifractal theory. AFM images were evaluate adaxial and abaxial sides leaf. The 3D maps revealed side is dominated by stomach cells, while striated structures observed...

Cancer is now a global concern, and control of the function of cancer cells is recognized as an important challenge. Although many aggressive chemical and radiation methods are in practice to eliminate cancer cells, most imply severe adverse toxic effects on patients. Taking advantage of natural physical differences between cancer and normal cells might benefit the patient with more specific cy...
