Additive Manufacturing (AM), and more specifically Fused Filament Fabrication (FFF), allow the production of highly customized parts, provide enormous freedom-of-design can lead to material savings due layer-by-layer deposition that is inherent this family processes. FFF utilizes both amorphous semi-crystalline thermoplastic filaments as feedstock materials, offering a wider range materials compared some other polymer-based additive manufacturing techniques. However, current trend where FFF,...

Micro/nanoscale hierarchical structures of super-hydrophobic 3D printed PSU membranes and the switchable separation oil/water mixtures.
Alternative bisphenols, synthesized from lignin-derivable 4-<italic>n</italic>-propylguaiacol, show promising technical, sustainable and environmental advantages for various polymer applications.
A micro/nanoscale hierarchical ZIF-L layer on a 3D printed membrane for superhydrophobic and underwater superoleophobic surfaces.
The addition of 0.1 wt % carbon nanoparticles significantly improved the optical absorption and flowability gas-atomized copper powder. This facilitated selective laser melting (SLM) by reducing required energy density to obtain 98% dense parts. Moreover, led an in situ de-oxidation parts during SLM process. properties as-built were limited a tensile strength 125 MPa, ductility 3%, electrical conductivity 22.7 × 106 S/m, despite advantageous effect on powder characteristics behavior. modest...

The breakup of Newtonian droplets in a matrix during shear flow is investigated counterrotating parallel plate device. For bulk conditions, the critical capillary number for known to be only determined by viscosity ratio. Here, we show that also affected degree confinement: low ratios, confinement suppresses breakup, whereas high promotes breakup. This way, above value confinement, even with ratio larger than 4, which are unbreakable situation, can broken simple field.
The bulk dynamics of immiscible polymer blends during flow is relatively well understood, especially when the system contains Newtonian components. Recently, a number studies have focused on in confined geometries. In that case, morphology development not only affected by material characteristics and type flow, but also degree confinement. Here, we present an overview two-phase shear flow. Firstly, focus typical microstructures are observed dilute blends. Secondly, order to understand those...
Having been inspired by formose-based hypotheses surrounding the origin of life, we report on a novel catalytic route toward series recently discovered four-carbon α-hydroxy acids (AHA) and their esters from accessible renewable glycolaldehyde (GA) in various solvents. The synthesis follows cascade type reaction network, its mechanism with identification rate-determining step was investigated situ 13C NMR. mechanistic understanding led to optimized conditions higher overall rates AHA...
Different types of healing agents have already been tested on their efficiency for use in self-healing cementitious materials. Generally, commercial are used while properties adjusted manual crack repair and not autonomous healing. Consequently, the amount regain due to cracks is limited. In this research, a methyl methacrylate (MMA)-based agent was developed specifically Various parameters were optimized including viscosity, curing time, strength, etc. After desired obtained, encapsulated...
This work investigates the influence of powder size/shape on selective laser sintering (SLS) a thermoplastic polyurethane (TPU) elastomer. It examines TPU which had been cryogenically milled in two different sizes; coarse (D50∼200μm) with rough surfaces comparison fine (D50∼63μm) extremely flow additives. is found that coalesces at lower temperatures and excessively smokes during SLS processing. In comparison, additives better processable significantly higher bed temperatures, allowing...

Traditionally, laboratory practice aims to establish schemas learned by students in theoretical courses through concrete experiences. However, access laboratories might not always be available students. Therefore, it is advantageous diversify the tools that could use train practical skills. This technology report describes design, development, and first testing of a mobile augmented reality application enables hands-on learning experience titration experiment. Additionally, presents...
