Algae-Filler Artificial Timber with an Ultralow Binder Content [PDF]

arXiv, 2020
Algae cultivation is an active area of study for carbon sequestration, while the large amount of produced algae must be upcycled. In the current study, we fabricated artificial timber based on algae filler, with only 2~4% epoxy binder. The flexural strength could be comparable with those of softwoods.

Bioinspired Strong and Tough Layered Bulk Composites via Mycelial Interface Anchoring Strategy

Advanced Science, EarlyView.
An interface anchoring strategy, which fixes the interface between the soft and hard phases to immobilize 2D materials, by leveraging the growth of biological living mycelium is proposed. This approach results in the formation of a lightweight and strong composite material (the LBCs) with a layered structure composed of soft and hard phases.

Unraveling the Interfacial Properties of Twisted Single‐Crystal Au(111)/MoS2 Heterostructures: A Pathway to Robust Superlubricity

Advanced Science, EarlyView.
Interfacial mechanical properties of MoS2/Au(111) heterostructures are revealed by advanced experimental and computational methods. The developed semi‐anisotropic interlayer potential (SAIP) accurately predicts moiré‐driven out‐of‐plane corrugation, aligning with experimental observations.

Flexural vs. tensile strength in brittle materials

Comptes Rendus. Mécanique, 2015
The tests leading to the determination of the strength of brittle materials show a very wide scattering and a noticeable difference between flexural and tensile strengths. The corresponding statistics are usually described by the Weibull law, which only partly explained the observed difference.

Investigating the Composite/Metal Interface and its Influence on the Electrical Resistance Measurement [PDF]

arXiv, 2018
The advantages introduced by carbon fiber reinforced polymer (CFRP) composites has made them an appropriate choice in many applications and an ideal replacement for conventional materials. The benefits using CFRP composites are due to their lightweight, high stiffness, as well as corrosion resistance.

Boosting the Efficiency and Mechanical Stability of Organic Solar Cells Through a Polymer Acceptor by Reducing the Elastic Modulus

Advanced Energy Materials, EarlyView.
Herein, PYSe2F‐T is first applied to simultaneously improve the performance and mechanical stability of organic solar cells compared with mPh4F‐TS as the counterpart. Meanwhile, a detailed crack density analysis is first employed to evaluate the relationship between mechanical stability and elastic modulus of active layers, which can be reduced by the ...
