Summary: This study investigates the disruption of phosphorene oxide (PO) to a protein structure and finds that the disruption is enhanced with increasing oxidation concentration of PO. The oxidation mode of PO has limited effect on the interaction between PO and the protein. PO with low oxidation concentration is biocompatible with the protein. Oxygen atoms filling into the surface of phosphorene enhance its interaction with the protein and increase the disruption. The electrostatic interaction between PO and the protein has negligible effect on the structural damage. These findings have implications for the biological toxicity and potential biomedical applications of PO nanosheets.

Summary: Gene therapy has become a forefront treatment for various diseases. However, the clinical application of graphene oxide as a gene vector is limited due to the lack of homogeneity in different synthetic methods. In this study, a new class of graphene oxide called oxo-G was prepared with controlled size and surface chemistry. After functionalization, oxo-G was able to efficiently complex siRNA and induce gene silencing in vitro at doses more than 20 times lower than previous graphene-based materials. This work aims to inspire further development of oxo-G materials for biomedical applications, with the hope that oxo-G can be considered as an alternative candidate for future in vivo gene silencing.

Summary: We investigate the swelling mechanism of graphene oxide (GO) membranes exposed to different relative humidity (RH) values using Grand Canonical Monte Carlo simulations. Our study reveals that the structure of GO membranes changes as water is adsorbed and the graphene oxide flakes become charged and swell. We find that the surface charge of the flakes drives the water adsorption mechanism, and the membrane undergoes structural changes only at very high relative humidity.

Summary: The physicochemical properties of nanomaterials have an impact on their toxicity and pathogenicity, with nanotopography being an important factor. Despite its significance, the role of surface topography in nanotoxicity is often overlooked. By manipulating surface topography and applying principles from catalysis, it is possible to create safer nanomaterials by reducing surface properties contributing to toxicity.

Summary: This study investigates head-on and overtaking collisions of solitary waves in a 2D hexagonal packing, finding that the velocity amplitude of the waves is proportional to the impacting velocity. In head-on collisions, waves with equal amplitude have a power exponent of -0.202, while waves with unequal amplitudes have a power exponent of -0.656. During overtaking collisions, fast waves have a positive phase shift while slow waves have a negative phase shift, and the phase shift is related to the impacting velocity with a power exponent.

Summary: In this paper, the evolution and collision of wave fronts in a 2D hexagonal packing confined in a rectangular region are investigated. Different impacts, including one impact, continuous impacts, and discontinuous impacts, are considered. Numerical results show that the phase and peak amplitude of the wave front are related to the distance from the center of the wave front, and the attenuation of velocity varies at each position of the wave front with increasing propagating depth. Discontinuous impacts can lead to the merging of independent wave fronts, while continuous impacts result in slower decay of the peak amplitude. When impacts are periodically distributed, the wave fronts eventually evolve into a uniform wave front that can be described by Nesterenko's continuum approximation of a 1D chain of spheres.

Summary: The emergence of SARS-CoV-2 has caused a global alarm, leading to extensive research on repurposing drugs to treat the infection. Researchers have found that a metabolite of the drug fenofibrate, called fenofibric acid (FA), can destabilize the receptor-binding domain (RBD) of the viral spike protein, inhibiting its binding to the hACE2 receptor. Through molecular dynamics simulations, the study identified a potential cryptic binding site for FA on the RBD and demonstrated that FA alters the conformation of the binding loop, reducing its affinity for ACE2. This research provides new insights for designing SARS-CoV-2 inhibitors targeting cryptic sites on the RBD.

Summary: Using optical microscopy and multiparticle tracking techniques, the correlated diffusion of colloidal particles over a rugged surface was investigated. The hydrodynamic interactions of the particles confined to energy landscapes displayed a distinct power-law behavior. The local energy landscape on the rugged surface reduced the long-range hydrodynamic interactions between colloidal particles. The findings provide physical insights into confinement hydrodynamics and have implications for designing material surfaces and controlling particle motion on rough surfaces.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
