Information Security for Libraries [PDF]

open access: yes, 2002
Libraries have made significant investments in computer-based resources, training and services. However, such investments need to be protected from misuse or mistake by taking an active role in information security.

Single‐Step Conversion of Metal Impurities in CNTs to Electroactive Metallic Nitride Nanoclusters for Electrochemical CO2 Reduction

open access: yesAdvanced Functional Materials, EarlyView.
A single‐step, low‐temperature co‐pyrolysis process removes encapsulated seed metal NPs (10–50 nm) from CNTs, redistributing them as surface‐anchored metal and metal–nitride NCs (1–1.5 nm). Herein, Ni3N NCs achieve an ultra‐low onset overpotential for CO2 reduction to CO with >98% Faradaic efficiency across 100–700 mA cm−2.

Green Solvent Enabled Perovskite Ink for Ambient‐Air‐Processed Efficient Inkjet‐Printed Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
This study explores an eco‐friendly solvent with 1,3‐dimethyl‐2‐imidazolidinone for developing perovskite ink, enhancing grain size and formation of purer phase perovskite. The inkjet‐printed perovskite solar cells demonstrated a remarkable improvement in device power conversion efficiency from 14.6% to almost 17.8%, highlighting sustainable innovation
