Low‐toxicity metal–organic frameworks: Sustainable solutions for versatile applications

Bulletin of the Korean Chemical Society, Volume 46, Issue 3, Page 265-280, March 2025.
Developing low‐toxicity Metal‐organic Frameworks (MOFs) involves challenges related to stability, scalability, and cost‐effectiveness. Research now focuses on improving MOF design to enhance robustness and exploring greener synthesis methods to minimize environmental impact. Abstract The conventional synthesis of metal‐organic framework (MOF) materials

Recent Sociocultural Changes Reverse the Long‐Term Trend of Declining Habitat Availability for Large Wild Mammals in Europe

Diversity and Distributions, Volume 30, Issue 12, December 2024.
ABSTRACT Aim People have strongly influenced the biosphere for millennia, but how their increasing activities have shaped wildlife distribution is incompletely understood. We examined how the distribution of European large (>8 kg), wild mammals has changed in association with changing anthropogenic pressures and climate change through the Holocene ...

FEM stress analysis of the cooling hole of an HPDC die

IOP Conference Series: Materials Science and Engineering, 2015
Cracking at a cooling hole is a typical die failure mode in a high-pressure die-casting (HPDC) die. We simulated the thermal distortion of a die considering the HPDC machine deflection and revealed a stress concentration at the cooling hole. The stress concentration at the cooling hole changes after injection or after spraying and blowing air.
