摘要:Discussions around global equity and justice in science typically emphasize the lack of diversity in the editorial boards of scientific journals, inequities in authorship, parachute research, dominance of the English language, or scientific awards garnered predominantly by Global North scientists. These inequities are pervasive and must be redressed. But there is a bigger problem. The legacy of colonialism in scientific research includes an intellectual property system that favors Global North...

摘要:Materials often fail prematurely or catastrophically under load while containing voids, posing a challenge to materials manufacturing. We found that a metal (gold) containing spherical voids with a fraction of up to 10% does not fracture prematurely in tension when the voids are shrunk to the submicron or nanometer scale. Instead, the dispersed nanovoids increase the strength and ductility of the material while simultaneously reducing its weight. Apart from the suppressed stress or strain conc...

摘要:Pure metal nanowires (NWs) are one-dimensional nanomaterials with distinctive properties for various applications. Nevertheless, mass-growth forests have not been developed because of vapor pressure limitations, chemical reduction problems, or both. We succeeded in the mass growth of aluminum (Al) NW forests at desired locations by controlling atomic diffusion within the solid film. Whereas prior attention has focused only on how to increase the driving force, we show that focused ion beam irr...

摘要:Flexible integration spurs diverse applications in metal-organic frameworks (MOFs). However, current configurations suffer from the trade-off between MOF loadings and mechanical compliance. We report a wrinkled configuration of MOF thin films. We established an interfacial synthesis confined and controlled by a polymer topcoat and achieved multiple Turing motifs in the wrinkled thin films. These films have complete MOF surface coverage and exhibit strain tolerance up to 53.2%. The enhanced mec...
