Microemulsion mediated synthesis of BaTiO3 – Ag nanocomposites [PDF]

open access: yesProcessing and Application of Ceramics, 2009
BaTiO3 – Ag composite nanopowders were synthesized via microemulsion mediated synthesis through the hydrolytic decomposition of mixed metal alkoxide solutions as precursor for the BaTiO3 and the reduction of silver nitrate in the presence of ...

University teaching of mass spectrometry as a key practical technique within the context of a fully integrated, spiral curriculum

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
Rationale Mass spectrometry (MS) is introduced to high school students in the UK in many pre‐university course syllabi. As such, we have identified the use of MS as a key technique that should be taught practically to undergraduates from the outset of their studies.

Solubility Challenges and Strategies for Organic Sodium‐Ion Batteries: Status and Perspectives

open access: yesSmall, EarlyView.
Organic sodium‐ion batteries (OSIBs) have garnered interest due to their low cost, abundant resources, and sustainability. However, the solubility of organic materials in aprotic electrolytes results in electrode deterioration, active material loss, and poor cycling stability.

Harnessing Carbenoid Reactivity From Imidazoles and Oxiranes

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 4, 17 February 2026.
The combination of azole compounds and oxiranes exhibits carbenoid reactivity at elevated temperatures, as demonstrated by the successful benzoin condensation of aromatic aldehydes. Using this catalytic system to polymerize bifunctional aldehyde/oxirane monomers yields thermosets with glass transition temperatures above 100°C.

Intermolecular Enantioselective Nickel‐Catalyzed Arylation of Un‐Activated C(sp3)─H Bond

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 7, 9 February 2026.
Ni: a new solution for asymmetric C(sp3)─H activation. The stereoselective synthesis of all‐carbon quaternary stereogenic centres is achieved via enantioselective C(sp3)─H arylation using a Ni‐BINOL‐derived catalyst. Rational catalytic cycle design uncovers a new reaction pathway that can efficiently induce chiral information during the stereoselective

Stabilizing Frustrated Phase Transitions in Selective Oxidation Reactions

open access: yesAdvanced Materials, Volume 38, Issue 8, 6 February 2026.
Using multimodal operando spectromicroscopy, the frustrated phase transition responsible for selective oxidation over cobalt oxide spinel catalysts is identified, corresponding to combined surface reaction and Mars‐van Krevelen (MvK) dynamics. This regime is disrupted by the formation of mobile vacancies and the depletion of active oxygen at high ...

Room‐Temperature, Photo‐Densified High Refractive Index Titanium Oxide Thin Films for Solution‐Processed Flexible Bragg Mirrors and Microcavity OLEDs

open access: yesAdvanced Optical Materials, Volume 14, Issue 6, 9 February 2026.
This paper presents the room‐temperature fabrication of solution‐processed, high refractive index TiOX thin films via photo‐densification. Using these films, flexible Bragg mirrors are demonstrated on PET substrates, achieving a high reflectivity of 96% at 450 nm.

Smart REASSURED Sensors via Machine‐Augmented Printable On‐Paper Arrays

open access: yesAdvanced Sensor Research, Volume 5, Issue 2, February 2026.
This perspective highlights the emerging role of pattern‐recognition, printable on‐paper sensor arrays for intelligent PoC diagnostics. It discusses how paper's inherent limitations can be overcome through surface modification and scalable printing, and how machine‐learning analysis of cross‐reactive arrays enables multiplexed, low‐cost, and REASSURED ...
