Surface Tension Measurement of Ti‐6Al‐4V by Falling Droplet Method in Oxygen‐Free Atmosphere

open access: yesAdvanced Engineering Materials, EarlyView.
In this article, the temperature‐dependent surface tension of free falling, oscillating Ti‐6Al‐4V droplets is investigated in both argon and monosilane doped, oxygen‐free atmosphere. Droplet temperature and oscillation are captured with one single high‐speed camera, and the surface tension is calculated with Rayleigh's formula.

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

open access: yesAdvanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Exploring Food, Agricultural, and Environmental Law and Policy Reforms

open access: yesJournal of Agriculture, Food Systems, and Community Development, 2016
First paragraphs: Books have played an important role in shaping the United States' food, agricultural, and environmental systems. One of the most influential is a1906 book entitled The Jungle written by Upton Sinclair that used investigative reporting ...

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy

open access: yesAdvanced Engineering Materials, EarlyView.
This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

Beyond central-local relations: the introduction of a new perspective on China’s environmental governance model

open access: yesHumanities & Social Sciences Communications
In recent years, the Chinese government has initiated assertive centralization efforts in its approach to environmental governance. However, the efficacy of these initiatives demonstrates marked variability across different sectors.

Thirty Years of Environmental Protection Law in the Supreme Court [PDF]

open access: yes, 2000
It is an honor to present a lecture named after Lloyd Garrison and to be here at Pace Law School. It is especially fitting, of course, that the first Garrison Lecture was presented by Pace\u27s own David Sive.

Numerical Exploration of Thermal Shock Resistance in MgO–C Refractories

open access: yesAdvanced Engineering Materials, EarlyView.
A mesostructure‐resolved numerical framework is developed to evaluate the thermal shock resistance of MgO–C refractories. By modeling interface debonding under rapid temperature changes and introducing a modified thermal shock parameter that accounts for mesocracks, the study shows how graphite content and aggregate size influence thermal shock ...
