Pressed lithium disilicate glass ceramics: Microstructural characterization, in vitro and in silico nonlinear dynamic analysis for biaxial flexural strength

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the mechanical properties of lithium disilicates, and to assess the predictive capability of in silico models for biaxial flexural strength (BFS). Materials and Methods Specimens of four heat‐pressed lithium disilicates (IPS e.max Press, Rosetta SP, LiSi Press, Vintage Prime Press) were obtained.

Quasi‐Standard Platform of AlScN Piezoelectric Integrated MEMS Technology (PIMT) For Multi‐Project Wafer Fabrication

Advanced Sensor Research, Volume 5, Issue 8, August 2026.
This report presents an 8‐inch quasi‐standard piezoelectric integrated MEMS technology (PIMT) platform which, through the integration of core and additional processes, reliably supports three rounds of multi‐project wafer (MPW) fabrication. Whilst ensuring support for mass production processes, the platform offers certain flexibility, providing a ...

The experimental study of energy dissipation during fatigue crack propagation under biaxial loading

Fracture and Structural Integrity, 2019
The work is devoted to experimental study of heat flux evolution at the fatigue crack tip during biaxial loading with a goal to relate the heat flux to the rate of crack propagation under different loading conditions. The plane samples of titanium alloy (

How Can We Improve the Assessment and Indifferent Outcomes From Pelvic Organ Prolapse Management From Conservative and Surgical Therapies? ICI‐RS 2025

Neurourology and Urodynamics, Volume 45, Issue 6, Page 1220-1229, August 2026.
ABSTRACT Introduction Pelvic organ prolapse is a common condition and many women seek surgical treatment for prolapse symptoms. However, recurrence of prolapse after surgical treatment is common. A think tank was held at ICI‐RS 2025 to discuss how the assessment and indifferent results from conservative and surgical management can be improved.

A Hybrid Compliant–Tendon Laparoscopic Instrument for Distal Articulation and Grasping: Design and Experimental Validation

The International Journal of Medical Robotics and Computer Assisted Surgery, Volume 22, Issue 4, August 2026.
ABSTRACT Background Conventional laparoscopic instruments provide limited dexterity in confined anatomical environments, whereas existing articulated designs rely on complex rigid joints or motorised actuation, increasing mechanical complexity and limiting miniaturisation.

Toughening of TiO2 via Femtosecond Laser Shock Peening

Journal of the American Ceramic Society, Volume 109, Issue 8, August 2026.
ABSTRACT Most ceramics have low fracture toughness (<5 MPa m$\sqrt{m}$) at room temperature. This work explores the feasibility of toughening TiO2 via femtosecond laser shock peening (fs‐LSP). Transmission electron microscopy (TEM) analyses reveal LSP‐induced the creation of high‐density stacking faults, dislocation structures, and twin boundaries in ...

A Novel Framework for Understanding Multiaxial Fatigue of SBR Through Monitored Tension‐Torsion Tests

Strain, Volume 62, Issue 4, August 2026.
A new methodology shows that current multiaxiall fatigue criteria are not sufficient. ABSTRACT In the present work, mappings of two invariants of the true strain tensor, K2$$ {K}_2 $$ that measures the magnitude of the distortion and K3$$ {K}_3 $$ that quantifies the mode of distortion, are used to investigate the multiaxial fatigue of AE2 and AE42 ...
