The Association of American Universities (AAU) and the Association of Public and Land-grant Universities (APLU) have collaborated and led national discussions to improve public access to data resulting from federally funded research. As part of the NSF-funded (NSF # 1939279) Accelerating Public Access to Research Data Initiative, AAU and APLU convened representatives from the university teams at an Acceleration Conference in 2020 and facilitated two national Summits to help universities create robust systems for ensuring effective public access to high-quality research data and develop the current Guide. The Guide has been informed by 261 campus representatives from 111 institutions, representatives from several federal agencies, and other key stakeholders. The Guide is designed to help institutions develop and promote systems to support sharing of research data. It provides advice concerning actions that can be taken to improve access to research data on campuses. It also contains information about the infrastructure and support that may be required to facilitate data access, and it offers specific examples of how various institutions are approaching challenges to sharing research data and results.
Colloidal semiconductor nanocrystals (NCs) represent a promising class of nanomaterials for lasing applications. Currently, one of the key challenges facing the development of high-performance NC optical gain media lies in enhancing the lifetime of biexciton populations. This usually requires the employment of charge-delocalizing particle architectures, such as core/shell NCs, nanorods, and nanoplatelets. Here, we report on a two-dimensional nanoshell quantum dot (QD) morphology that enables a strong delocalization of photoinduced charges, leading to enhanced biexciton lifetimes and low lasing thresholds. A unique combination of a large exciton volume and a smoothed potential gradient across interfaces of the reported CdS bulk /CdSe/CdS shell (core/shell/shell) nanoshell QDs results in strong suppression of Auger processes, which was manifested in this work though the observation of stable amplified stimulated emission (ASE) at low pump fluences. An extensive charge delocalization in nanoshell QDs was confirmed by transient absorption measurements, showing that the presence of a bulk-size core in CdS bulk /CdSe/CdS shell QDs reduces exciton–exciton interactions. Overall, present findings demonstrate unique advantages of the nanoshell QD architecture as a promising optical gain medium in solid-state lighting and lasing applications.
