Open textbooks – an untapped opportunity for universities, colleges and schools

open access: yesInsights: The UKSG Journal, 2018
The pilot phase of the UK Open Textbook project reached completion in April 2018. This article discusses the project, what open textbooks are, and why they are an untapped opportunity for universities, colleges and schools.

POM‐Based Water Splitting Catalyst Under Acid Conditions Driven by Its Assembly on Carbon Nanotubes

open access: yesAdvanced Materials, EarlyView.
A newly‐engineered POM‐based electrocatalyst incorporating non‐innocent counter cations exhibits fast kinetics for either the OER or HER under strongly acidic conditions (1 m H2SO4), depending on whether it is assembled on carbon nanotubes (1@CNT) or physically mixed with them (1/CNT). In water‐splitting tests using a two‐electrode setup, these systems

Phase Boundary Engineering of Co2P‐CoP Branched Nanoparticles Enhances Cobalt Oxidation for Oxygen Evolution Electrocatalysis

open access: yesAdvanced Materials, EarlyView.
Phase boundaries between Co2P and CoP are constructed through a controlled transformation of Co to Co2P‐CoP branched nanoparticles. The polycrystalline mixed‐phase Co2P‐CoP branches are enriched with phase boundaries that stabilize Co active sites for OER. This work highlights phase boundary engineering as a powerful approach to tailor active sites and

Recent Progress in the Phase‐Controlled Synthesis of Ruthenium Nanocrystals for Catalytic Applications

open access: yesAdvanced Materials, EarlyView.
Template effect and kinetic control enable crystal‐phase engineering of Ru nanocrystals, granting access to either metastable fcc‐Ru or stable hcp‐Ru with distinct surface structures, thermal stabilities, and catalytic behaviors. Moreover, the hcp‐Ru can further serve as an epitaxial template to direct Pd and Rh nanocrystals into the metastable hcp ...

Chapter 04. Framework to understand postgraduate students' adaption of academics' teaching materials as OER [PDF]

open access: yes, 2011
This chapter addresses a way of responding to one of the key challenges of OER contribution, namely academics' lack of time to re-purpose teaching materials originally intended for campus-based face-to-face lectures as stand-alone Open Educational ...

Mary Lou Forward-International OER Initiatives: OER Community Conversations [PDF]

open access: yes, 2010
OER is a wide term, encompassing different concepts. Many people appreciated Steve Carson's description of different roles that OER can fill as summarized by Thomas Pfeffer: OER as a substitute, OER as a reusable resource, OER as transparency, and OER ...

Laplace‐Pressure‐Stabilized Rutile Solid‐Solution Catalysts for Acidic Water Oxidation: Enabling DSA‐Inspired Compositions

open access: yesAdvanced Materials, EarlyView.
The miscibility of foreign elements in rutile‐type IrO2 and SnO2 is greatly enhanced under high Laplace pressure, where their crystal size is reduced to the nanoscale. This enhancement leads to the successful synthesis of DSA‐composition solid‐solution nanocatalysts with notable durability during the acidic OER in water electrolysis.
