Achieving high-strength metallurgical bonding between A356 aluminum and copper through compound casting
(Peer reviewed; Journal article, 2021)Due to stable surface oxides on the solid copper surface and the ease of forming Al2O3 films at the aluminum melt surface, it is difficult to achieve high-strength metallurgical bonding between the two materials through ... -
Achieving superior dispersion-strengthening effect in an AA5xxx Al-Mg-Mn alloy by mico-alloying
(Peer reviewed; Journal article, 2023)5xxx Al-Mg based alloys are widely applied as non-heat-treatable alloys. In this work, we designed a dispersion-strengthening Al-4Mg-1Mn-0.3Fe-0.2Si-0.2Zr-0.2Cr (wt.%) alloy. By applying ramp heating and 400 °C isothermal ... -
Achieving ultrahigh strength in binary Al-10Mg alloy through heavy cryogenic rolling
(Peer reviewed; Journal article, 2022)Al-Mg alloys with high Mg contents have attracted considerable interest given enhanced strength and simultaneously reduced density by high Mg solute concentrations. In the present study, we proposed a strategy of strengthening ... -
Activation of multiple stress responses in Staphylococcus aureus substantially lowers the minimal inhibitory concentration when combining two novel antibiotic drug candidates
(Peer reviewed; Journal article, 2023)The past few decades have been plagued by an increasing number of infections caused by antibiotic resistant bacteria. To mitigate the rise in untreatable infections, we need new antibiotics with novel targets and drug ... -
