The primary goal of this study was to characterize the influence of the pore-saturated gas media and their physical properties on the elasticity of porous ceramic materials. Resonant ultrasound spectroscopic measurements were performed on test specimens of alumina with ~40% porosity, zirconia with ~48% porosity, and sintered fully dense zirconia to determine the hydrostatic pressure-dependent macroscopic elasticity. Here, we report the variation of elasticity of porous and full dense samples over approximately five orders of magnitude (800-0.02 psi) in absolute pressure. The time evolution of mechanical equilibrium of the porous materials at low pressure and high-temperature conditions will also be discussed.

Introduction: Diabetes mellitus (DM) is a chronic metabolic disorder that increases fragility fracture risk. Conventional DXA-based areal bone mineral density (aBMD) assessments often underestimate this risk. Cortical Backscatter (CortBS) ultrasound, a radiation-free technique, non-invasively analyzes cortical bone's viscoelastic and microstructural properties.

The application of nanocomposites based on polyacrylamide hydrogels as well as silica nanoparticles in various tasks related to the petroleum industry has been rapidly developing in the last 10-15 years. Analysis of the literature has shown that the introduction of nanoparticles into hydrogels significantly increases their structural and mechanical characteristics and improves their thermal stability. Nanocomposites based on hydrogels are used in different technological processes of oil production: for conformance control, water shutoff in production wells, and well killing with loss circulation control.

Lightweight cellular materials with high stiffness and excellent recoverability are critically important in structural engineering applications, but the intrinsic conflict between these two properties presents a significant challenge. Here, a topological cellular hierarchy is presented, designed to fabricate ultra-stiff (>10 MPa modulus) yet super-elastic (>90% recoverable strain) graphene aerogels. This topological cellular hierarchy, composed of massive corrugated pores and nanowalls, is designed to carry high loads through predominantly reversible buckling within the honeycomb framework.

Wound healing is a complex process involving a sequence of factors that can be disrupted, negatively impacting the quality of life for patients and overburdening healthcare systems. Advanced dressings obtained by electrospinning are highlighted by the optimization of this process, allowing air exchange and protection against microorganisms. Aiming to develop bioactive dressings, this study investigated the physicochemical, mechanical, microbiological, and in vitro biological properties of membranes containing 25 %, 50 %, 75 %, and 90 % copaiba oil (CO) co-electrospun with poly(L-co-D,L-lactic acid) (PLDLA) and natural rubber latex (NR).

Due to the limited self-regeneration capacity of bone, medical interventions is often required for large segmental bone defects. In this study, the application of porous titanium alloy (Ti6Al4V) scaffold in bone defect repair was investigated. Owing to its excellent mechanical properties and biocompatibility, Ti6Al4V is a preferred choice for orthopedic implants.
