2018 Top Trends in Academic Libraries

Every other year, the ACRL Research Planning and Review Committee produces a document on top trends in higher education as they relate to academic librarianship. Topics in this edition of ACRL Top Trends will be familiar to some readers who will hopefully learn of new materials to expand their knowledge. Other readers will be made aware of trends that are outside of their experience. This is the nature of trends in our current technological and educational environments: change is continual, but it affects different libraries at different rates. The 2018 top trends share several overarching themes, including the impact of market forces, technology, and the political environment on libraries

Synthesis of ZnO nanocrystals by subsequent implantation of Zn and O species

We report the preparation of ZnO nanocrystals embedded in a SiO2 matrix formed using sequential zinc and oxygen ion implantations. The optical absorption spectra and photoemission spectra of zinc implanted and zinc/oxygen coimplanted silica show that the first zinc implantation produces zinc clusters and that the subsequent oxygen implantation following the zinc implantation rearranges the distribution of zinc and oxygen ions at an atomic level. While thermal annealing of Zn only implanted silica leads to the formation of Zn nanocrystals, thermal annealing of zinc/oxygen coimplanted silica promotes the growth of ZnO nanocrystals. The absorption and photoluminescence spectra show that ZnO nanocrystals form in an amorphous SiO2 matrix and that their systematic change as a function of annealing temperature corresponds to the typical correlation between the increase of particle size and a redshift in near-band-edge emission.Peer reviewedMechanical and Aerospace Engineerin

Environmental Scan 2019

Every two years, the ACRL Research Planning and Review Committee writes an Environmental Scan, a summary of the key themes in libraries and higher education. Many topics in this arena are in a state of perpetual change. This year’s scan focuses largely on developments from the last two years (2017 and 20018) in long standing themes primarily centered in the U.S. In some cases these build on last year’s Top Trends and there are a few instances of notable events that may indicate larger changes to come. The 2019 Environmental Scan will provide an overview for all librarians working in or with an interest in higher education. Since changes can unfold over years, those deeply interested in this landscape should also consult the RPRC documents for the last four years. The footnotes provide a solid starting point for taking a deeper dive into these topics
