Bioinspired microstructure design simultaneously enhances strain-rate stiffening and toughening of composites, Qi, et al., Engineering Fracture Mechanics, 2024
Novelty:
Propose and prove that microstructure significantly affects strain-rate dependent mechanical properties of composites, expanding the current knowledge that the strain-rate dependence is mostly due to material attributes.
A micromechanical model for bioinspired nanocomposites with interphase, Xia, Geng, Zhang, Wang, Composite Structures, 2023

The upside-down water collection system of Syntrichia caninervis, Pan, Pitt, Zhang, Wu, Tao and Truscott, Nature Plants, 2016
Novelty/impact/significance:
It is unveiled that the Syntrichia caninervis (S. caninervis), a most abundant desert moss, collects and transports water by coupling relevant nano- and microscale physical structures with multiscale sources of water (nanoscale nucleation, microscale fog droplet, larger droplets on awn).
Crack engineering for the construction of arbitrary hierarchical architectures, Li, Yu, etc., Wang, Ren, PNAS, 2019
Novelty/impact/significance:
A conventionally detrimental phenomenon, cracking (leads to material failure), is used as a beneficial aspect to develop a powerful replication technique (two curing stages for the elastomer mold) to construct bioinspired complex hierarchical structures for interesting functions and properties, ingenious and effective.
A droplet-based electricity generator with high instantaneous power density, Xu, Zheng, etc., Wang, Zeng, Wang, Nature, 2020
Novelty/impact/significance:
A novel water droplet-based electricity generator with significantly high instantaneous power density, several orders of magnitude higher over conventional equivalent ones, is developed. A new operating mechanism through the ingenious device design is presented.

Novelty/impact/significance:
A two-dimensional stress transfer model for platelet reinforcement, Hsueh, Composites Engineering, 1994
Significance:
Despite a few citations, this work provides classical analysis of the stress transfer problem in platelet-reinforced composites, the derivations of the platelet axial stress and interfacial shear stress distributions considering effects of the ends bonding/debonding and the matrix axial stress varying axially and transversely.
5.1 Elastic stress transfer, in Chapter 5. Composite mechanics: Short fibers, in Load Bearing Fiber Composites, by Michael R. Piggott, 2002
This time reading notes on a section of a well-known mechanics book are presented, due to its extreme clarity and reader-friendliness in explaining the stress transfer in fiber-reinforced composites. Personal understanding for the micromechanical model and derivations are included accordingly without specific indications.
