Current challenges and future directions for institutional repositories: A systematic literature review. An Annual Review of Information Science and Technology (ARIST) paper

Journal of the Association for Information Science and Technology, Volume 77, Issue 1, Page 301-322, January 2026.
Abstract Institutional repositories (IRs) are essential in advancing Open Access and facilitating the dissemination of scholarly work. This systematic review examines the challenges faced by IRs in areas such as strategic alignment, content acquisition, funding, staffing, quality assurance, and technology.

Amine‐Based Chloroaluminate Ionic Liquids as Electrolytes for Aluminium Batteries: A Synthesis and Evaluation Study

Battery Energy, Volume 5, Issue 1, January 2026.
Novel amine‐based aluminium electrolyte with central electron‐dense Nitrogen displays solid state behaviour until 313 K and transitions to liquid phase as current is applied or drawn from the cell. This unique property can potentially be used in a solid‐state aluminium battery with limited self‐discharge at idle state with high conductivity and ...

Hydrophilic Poly(Iminopyridinium Ylide)s: Defining a New Chemical Space for Poly(ylide)s

Macromolecular Rapid Communications, Volume 47, Issue 1, 9 January 2026.
Poly(iminopyridinium ylide) (PIPY) is reported as an overall charge‐neutral hydrophilic polymer with good water‐solubility, stability across physiologically relevant pH levels, and minimal biomolecular interactions. PIPY shows prevention of insulin fibrillation, which highlights its protein‐stabilizing capacity.
