Wear Analysis of Friction Stir Processed AA7075-SiC-Graphite Hybrid Surface Composites

Lubricants, 2022
High specific strength and superior corrosion resistance are two key characteristics of the aerospace grade AA7075-T6 alloy. However, the surface behavior of AA7075-T6 is found to be deprived, because of its behavior of being prone to fretting fatigue ...

Origin of Negative Density and Modulus in Acoustic Metamaterials

, 2016
This paper provides a review and fundamental physical interpretation for the effective densities and moduli of acoustic metamaterials. We introduce the terminology of hidden force and hidden source of volume: the effective density or modulus is negative ...

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Spinon-holon interactions in an anisotropic t-J chain: a comprehensive study

, 2007
We consider a generalization of the one-dimensional t-J model with anisotropic spin-spin interactions. We show that the anisotropy leads to an effective attractive interaction between the spinon and holon excitations, resulting in a localized bound state.

Symmetry characterization of the collective modes of the phase diagram of the $\nu=0$ quantum Hall state in graphene: Mean-field and spontaneously broken symmetries [PDF]

, 2017
We devote this work to the study of the mean-field phase diagram of the $\nu=0$ quantum Hall state in bilayer graphene and the computation of the corresponding neutral collective modes, extending the results of recent works in the literature ...

Keratin 19 as a prognostic marker and contributing factor of metastasis and chemoresistance in high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.

Enhancing comigration-ability of Mg2Sn particles with Mg matrix via interphase segregation of Zn

Journal of Magnesium and Alloys
This study investigates the impact of Zn alloying on the dispersion of the reinforcing particle in Mg2Sn/Mg composites. In the composite, Zn manifests in three distinct forms: Zn segregation layer between MgMg2Sn, the solid solution and the MgZn2 phase.

Phonon softening and superconductivity in tellurium under pressure

, 1996
The phonon dispersion and the electron-phonon interaction for the $\beta$-Po and the bcc high pressure phases of tellurium are computed with density-functional perturbation theory.
