3D Anodic Alumina Nanoarchitectures: A Decade of Progress from Foundational Science to Functional Metamaterials

open access: yesAdvanced Materials, EarlyView.
Ordered three‐dimensional anodic aluminum oxide (3D‐AAO) nanoarchitectures with longitudinal and transverse pores enable architecture‐driven metamaterials. The review maps fabrication advances, including hybrid pulse anodization, and shows how 3D‐AAO templates tailor properties across magnetism, energy, catalysis, and sensing.

Electromagnetic Radiation Stimulated Learning in Perovskite Nickelates

open access: yesAdvanced Science, EarlyView.
ABSTRACT Biological plasticity refers to the ability of synapses to strengthen or weaken over time. These adaptive properties play a fundamental role in learning and memory, spanning many orders of magnitude in timescales. Short‐term plasticity (STP) arises from rapid correlative activity, while long‐term plasticity (LTP) is governed by slower ...

A Decision‐Making Model for Implementing Green Technology in Sustainable Building Projects

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Green technology (GT) adoption is pivotal for reconciling environmental stewardship with economic viability in the built environment, particularly in resource‐constrained emerging economies. However, empirical evidence on how specific GT drivers actively mitigate adoption barriers remains scarce.

Primary energy efficiency potentials of district heat driven refrigeration systems

open access: yesEnergy Reports, 2021
District heat driven absorption chillers (AChs) contribute to a higher utilisation of the district heating network in summer and thus to a reduction of the relative heat losses.

Environmental Management Accounting in Private Hospitals: Navigating Competing Strategic Priorities for Sustainable Decision‐Making

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Environmental management accounting (EMA) is increasingly recognised as essential for carbon governance, accountability and net zero transitions, yet research has overlooked how sustainability is negotiated within mission‐driven but commercially exposed service organisations such as private hospitals in developing economies, a sector often ...
