Cold atom confinement in an all-optical dark ring trap
, 2008 We demonstrate confinement of $^{85}$Rb atoms in a dark, toroidal optical trap. We use a spatial light modulator to convert a single blue-detuned Gaussian laser beam to a superposition of Laguerre-Gaussian modes that forms a ring-shaped intensity null ...

Small Structures, Volume 6, Issue 5, May 2025.Herein, AlCoCrFeNi2.1 is selected to produce lattice structures by selective laser melting. The as‐printed lattice structures consist of numerous colonies of nanosized eutectic lamellar structures which are bent and interwind with each other to form a woven microstructure. The unique microstructure leads to unprecedented effective metal strength, yield

TESOL Quarterly, EarlyView.Abstract Race and language collaborate in structuring educational inequities, creating urgency for teacher education to equip all teachers to equitably serve racialized multilinguals as antiracist language educators. Emphasizing the inseparability of racial and linguistic justice, this article examines teacher candidates' (TCs') learning journeys ...

Creativity and Innovation Management, EarlyView.ABSTRACT The literature lacks a comprehensive model examining the performance impact of certifying and maintaining standardised innovation management systems (SIMS) or clarifying the advantages of standardisation. This study addresses that gap by analysing the key determinants of the benefits associated with SIMS certification and maintenance.
