Impact of MgO Additions on the Oxidation Resistance and Compression Behavior of Vanadium Alloys
Advanced Engineering Materials, EarlyView.An increase in oxidation resistance at 600 °C is achieved for alloys containing more than 2.5 wt.% MgO. It has been established that, along with V2O5, MgO6V2, and Mg2O7V2 are formed, which are presumed to enhance oxidative stability. Furthermore, the possible transformation of Mg‐vanadates through reaction with CO2, which presumably occurs in this ...

International Journal of Ageing and Later Life, 2018 Gerontology has a longstanding tradition of researching the relationship between older adults and their socio-spatial environments. However, environmental gerontology often shares a positivistic understanding of space as either a “prosthetic” or a ...

Advanced Engineering Materials, EarlyView.Different Al/Al bimetals with a single engineered interface reveal how mechanical mismatch governs fatigue crack growth under cyclic loading. Additionally, loading–unloading–reloading tests link the microyielding behavior to the fatigue crack growth resistance, while crack‐path analysis reveals toughening mechanisms at the interface, highlighting ...

Advanced Engineering Materials, EarlyView.Controlling the Field Assisted Sintering Technology (FAST) parameters, dwell temperature and cooling rate, significantly influences the microstructural evolution in titanium aluminide GE4822. Significant γ‐lamellar colonies develop only upon cooling through the α‐transus.

Proceedings of the National Academy of Sciences, 2013 For scientists who study subseafloor sediment, it’s not unusual to spend a lot of time at sea aboard a ship with a gaping hole in its hull. Known as a moon pool, the hole serves as a portal for the ship’s weighty drilling equipment to retrieve core samples of seafloor sediment thousands of meters below. Aboard …

Integration of Low‐Voltage Nanoscale MoS2 Memristors on CMOS Microchips
Advanced Functional Materials, EarlyView.This article presents the first monolithic integration of nanoscale MoS2‐based memristors into the back‐end‐of‐line of foundry‐fabricated CMOS microchips in a one‐transistor‐one‐resistor (1T1R) architecture. The MoS2‐based 1T1R cells exhibit forming‐free, nonvolatile resistive switching with ultra‐low operating voltages, low cycle‐to‐cycle variability ...

Application of numerical simulation in the solid expandable tubular repair for casing damaged wells
Petroleum Exploration and Development, 2009 In order to analyze the stress, strain, and residual stress of the solid expandable tubular (SET) applied in repairing casing damaged wells and to analyze the internal tube changes, the SET finite element model is established by ANSYS; the boundary ...

Advanced Functional Materials, EarlyView.Sulfur fluoride exchange (SuFEx) is a powerful click platform, yet water‐compatible multifunctional linchpins remain elusive. Here, we report decagram‐scalable diazonium linchpins that enable rapid Pd‐catalyzed diversification and direct, catalyst‐free on‐DNA ligation in aqueous media.
