Determination of Frequency-Dependent Shear Modulus of Viscoelastic Layer via a Constrained Sandwich BeamPolymers - Tập 14 Số 18 - Trang 3751
Ludi Kang, C. T. Sun, Haosheng Liu, Bilong Liu
Viscoelastic material can significantly reduce the vibration energy and radiated noise of a structure, so it is widely used in lightweight sandwich structures. The accurate and efficient determination of the frequency-dependent complex modulus of viscoelastic material is the basis for the correct analysis of the vibro-acoustic behavior of sandwich structures. Based on the behavior of a san...... hiện toàn bộ
Lightweight High-Performance Polymer Composite for Automotive ApplicationsPolymers - Tập 11 Số 2 - Trang 326
Valentina Volpe, Sofia Lanzillo, Giovanni Affinita, Beniamino Villacci, Innocenzo Macchiarolo, Roberto Pantani
The automotive industry needs to produce plastic products with high dimensional accuracy and reduced weight, and this need drives the research toward less conventional industrial processes. The material that was adopted in this work is a glass-fiber-reinforced polyamide 66 (PA66), a material of great interest for the automotive industry because of its excellent properties, although being l...... hiện toàn bộ

In this study, the performances of red CsPbI3-based all-inorganic perovskite quantum-dot light-emitting diodes (IPQLEDs) employing polymeric crystalline Poly(3-hexylthiophene-2,5-diyl) (P3HT), poly(9-vinycarbazole) (PVK), Poly(N,N′-bis-4-butylphenyl-N,N′-bisphenyl)benzidine (Poly-TPD) and 9,9-Bis[4-[(4-ethenylphenyl)methoxy]phenyl]-N2,N7-di-1-naphthalenyl-N2,N7-diphenyl-9H-fluorene-2,7-dia...... hiện toàn bộ
Recent Advances in Biochar Polymer CompositesPolymers - Tập 14 Số 12 - Trang 2506
Mattia Bartoli, Rossella Arrigo, Giulio Malucelli, Alberto Tagliaferro, Donatella Duraccio
“Biochar” (BC) is the solid residue recovered from the thermal cracking of biomasses in an oxygen-poor atmosphere. Recently, BC has been increasingly explored as a sustainable, inexpensive, and viable alternative to traditional carbonaceous fillers for the development of polymer-based composites. In fact, BC exhibits high thermal stability, high surface area, and electrical conductivity; m...... hiện toàn bộ
Chemically Dual-Modified Biochar for the Effective Removal of Cr(VI) in SolutionPolymers - Tập 14 Số 1 - Trang 39
Juanjuan Yang, Yu Sheng, Yan Yue, Wenfei Liu, Quande Che, Honglei Chen, Hongfang Ma
Here, a dual-modification strategy using KMnO4 (potassium permanganate) and AlCl3·6H2O (aluminum chloride, hexahydrate) as co-modifiers to improve the Cr(VI) removal capacity of K2CO3 activated biochar is introduced. As a result, the dual-modified biochar with KMnO4 and AlCl3·6H2O has the calculated adsorption energy of −0.52 eV and −1.64 eV for HCrO4−, and −0.21 eV and −2.01 eV for Cr2O72...... hiện toàn bộ
Performance Investigation and Cost–Benefit Analysis of Recycled Tire Polymer Fiber-Reinforced Cemented Paste BackfillPolymers - Tập 14 Số 4 - Trang 708
Zhuoqun Yu, Yongyan Wang, Jianguang Li
To alleviate the environmental problems caused by scrap tire and tailings disposal, the performance of recycled tire polymer fiber (RTPF)-reinforced cemented paste backfill (CPB) was investigated. Ordinary CPB, commercial poly-propylene fiber (CPPF) and reinforced CPB were also investigated for comparison. Slump tests, unconfined compression tests and a cost–benefit analysis were conducted...... hiện toàn bộ
Processing of Syndiotactic Polystyrene to Microspheres for Part Manufacturing through Selective Laser SinteringPolymers - Tập 8 Số 11 - Trang 383
Nicolas Mys, An Verberckmoes, Ludwig Cardon
Syndiotactic polystyrene pellets were processed into powder form using mechanical (ball milling, rotor milling) and physicochemical (spray drying) techniques with the intention of using it as feed material for selective laser sintering. New materials are an important component in broadening the application window for selective laser sintering but must meet strict requirements to be used. P...... hiện toàn bộ
