The fused filament fabrication (FFF) process is characterized by fast local temperature decrease. Such characteristic usually leads to lower crystallinity degree in final printed parts when semi-crystalline polymers are used. By melt-compounding poly(lactic acid) (PLA) with its nucleating agent Talc, filaments of PLA/Talc composite were produced and used FFF. Through investigations static/dynamic mechanical thermal properties, morphology, the influence Talc on PLA based FFF revealed: after...
This article presents the effects of thermal annealing at elevated temperatures (> glass transition temperature Tg) on performance polymer parts via material extrusion 3D printing. Both semi-crystalline and amorphous filaments were used. As-printed designed to be then annealed 60, 110 150 °C for different durations ranging from 50 6400 s. The flexural strength Young's modulus increased by a maximum approximately 10%. increase was ascribed crystallisation development during annealing, as...
ABSTRACT This article presents research results showing that the property of fused deposition modeling (FDM) products is obtained jointly by careful control processing parameters, structure products, and composition material. In this manuscript, poly(lactic acid) (PLA) was incorporated with graphene or carbon nanotube (CNT) through repeated melt blending. Filament PLA/graphitic nano‐filler prepared used in FDM. Rheological thermal analysis were conducted to assess suitability composite as...
Abstract Inhibiting the shuttle effect of lithium polysulfides and accelerating their conversion kinetics are crucial for development high‐performance lithium–sulfur (Li–S) batteries. Herein, a modified template method is proposed to synthesize robust yolk–shell sulfur host that constructed by enveloping dispersive Fe 2 O 3 nanoparticles within Mn 4 nanosheet‐grafted hollow N‐doped porous carbon capsules (Fe @N‐PC/Mn ‐S). When applied as cathode Li–S batteries, as‐prepared ‐S can deliver...
A sugar-based bis-furan diepoxide (OmbFdE) was developed which imparted epoxy resins with excellent fire retardancy.
Magnetorheological (MR) damper is one of the most promising smart devices for dissipating seismic energy and reducing structural vibrations. The MR dampers with multiple coils are widely adopted to enhance output damping forces performance. In order study dynamic characteristics multicoil from a micro macro viewpoint, three-coil was designed manufactured in this paper. performance tests under different excitation currents, displacement amplitudes, frequencies, coil combinations were...
Purpose Ionizing radiation (IR) could induce damage such as DNA and oxidative stress. Natural products, like tea, have been demonstrated potential in mitigating these damages. However, the lack of efficient rapid screening methods for natural products hinders their widespread application. To address this challenge, study utilized Caenorhabditis elegans (C. elegans) an vivo model to investigate radioprotective products.
Abstract To improve the service life of high-speed steel tools, this paper studies influence laser treatment on wear resistance, hardening layer depth, and hardness tools. The results show that power, lap rate, scanning speed tools is from large to small. Laser surface can after about 922 HV, non-laser 418 0.5 times higher than hardening. After quenching, resistance has also been improved, rate quenching 0.0023% 0.001% lower 0.0033%, mechanism mainly abrasive wear. there are three areas...
Abstract Although tremendous efforts have been dedicated to developing environmentally friendly bio‐based waterborne polyurethane (WPU) dispersions from vegetable oil, the fabrication of WPU solely derived oil‐based polyol with excellent comprehensive properties is still challenging. In present work, novel castor oil and soy successfully modified by phosphorus‐nitrogen chain extender [bis(2‐hydroxyethyl)amino]‐methyl‐phosphonic acid dimethyl ester (BH). The structure films are characterized...
Optimal public investments in human capital through subsidizing private education or providing are considered an endogenous growth model with externalities. Subsidizing stimulates growth, improves welfare, and has no distributional effect. While reducing income inequality as the literature, hinders of average unless externalities strong enough reduces welfare median agent initial is sufficiently high. Societies high may provide will replace it subsidized some future periods converges....
