Additive manufacturing technologies have a lot of potential advantages for construction application, including increasing geometrical flexibility, reducing labor costs, and improving efficiency safety, they are in line with the sustainable development policy. However, full exploitation additive technology ceramic materials is currently limited. A promising solution these ranges seems to be geopolymers reinforced by short fibers, but their application requires better understanding behavior...
Abstract The development of environmentally friendly, multifunctional conductive membranes is an ideal candidate for future new electronic components. Some cellulose-based sensors have been studied, such as pressure sensors, hydrothermal flexible optoelectronic devices, and electrochemical energy storage, etc. However, there are very few studies on materials in Joule heating. In this study, we adopted a simple friendly silane crosslinking method to crosslink cellulose graphene oxide (GO)...
This study compares the effect of nanoscale and microscale zerovalent iron on natural freshwater microplankton over 21 days.
This study investigates the role of ultrasonic energy and zinc oxide nanoparticles (ZnO NPs) coating on thermophysiological properties woven fabrics. Thermophysiological were evaluated heat mass transfer basis. Alambeta moisture management tester used for thermal evaluation transportation. Furthermore, parameters applied to evaluate physical overall comfort properties, i.e. resistance, diffusivity, flow, wetting time, accumulative one-way transport index untreated ZnO treated samples. The...
Secondary and backscaterred electrons are the most common signals used for imaging in scanning electron microscopy. Generally, SE to obtain topographical contrast while BSE show differences chemical composition (so called Z-contrast).The aim of present work is possibilities techniques not-so-common information using BSE, as e.g. orientation contrast, residual stress, different allotropic modifications, etc.
This paper reports on an investigation treating a hard-milled surface as undergoing severe plastic deformation at elevated temperatures. exhibits remarkable magnetic anisotropy (expressed in term of Barkhausen noise). also shows that noise emission is function tool wear and the corresponding microstructure transformations initiated tool/machined interface. The discusses specific character bursts unusually high magnitude pulses, especially low degree wear. main causes can be seen structures...
To develop microbiologically safe nanofibrous materials, it is crucial to understand their interactions with microbial cells. Current research indicates that the morphology of nanofibers, particularly diameter fibers, may play a significant role in biofilm formation and retention. However, has not yet been determined how fiber poly-ε-caprolactone (PCL), one most widely used biopolymers, affects these interactions. In this study, two materials electrospun from PCL (PCL45 PCL80) different...
In this work, we developed a novel harp structure that collects water directly from fog in comparison with conventional Raschel mesh. Polyethylene (PE) monofilament was used as collector's element the harp. The mesh its particular design is quite anisotropic, shows elastic behavior breadth-wise while no stiffness exhibited transverse direction. A of collection yield for signifies harvesting rate four times higher than mesh, suggesting some alterations diameter and collector element....
Abstract In this study, we investigated how the chemical structural properties, mechanical and morphology of large‐size graphene platelets (LGPs) doped glass fabric (GF)/epoxy composites are affected by varying loading amounts LGPs. Scanning electron microscope results revealed that dispersion filling effect LGPs can improve flowability resin, reducing aggregation shrinkage resin on surface, thereby facilitating better infiltration coverage surface. From spectrum analysis, binding with epoxy...
The most challenging task in the preparation of magnetic poly(N-isopropylacrylamide) (Fe3O4-PNIPAAm) nanocomposites for bio-applications is to maximise their reactivity and stability. Emulsion polymerisation, situ precipitation physical addition were used produce Fe3O4-PNIPAAm-1, Fe3O4-PNIPAAm-2 Fe3O4-PNIPAAm-3, respectively. Their properties characterised using scanning electron microscopy (morphology), zeta-potential (surface charge), thermogravimetric analysis (stability), vibrating...
