Listening to Hong Kong children's perspectives through pretend play

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Quality in early childhood education and care (ECEC) has become an increasing concern in recent years. The issue has been regularly discussed by different stakeholders. However, the rising concern regarding quality in ECEC has not seriously taken into account children's perspectives.

Integrating Enzymes with Photoredox Catalysis for Conversion of Nitriles into Fluorinated Products

open access: yesChemCatChem, EarlyView.
Herein, we describe a novel method for producing highly sought‐after fluorinated compounds through the integration of nitrilase enzymes and iridium photoredox catalysis in a convenient one‐pot reaction. Our chemo‐ biocatalytic methodology delivers a range of fluorinated and fluoroalkylated products from simple nitrile precursors, in good yields, at ...

Mechanistic Understanding of Laser‐Induced Defect Engineering of Anisotropic Cobalt Oxide Spinel Platelets in Water

open access: yesChemCatChem, EarlyView.
Pulsed laser defect engineering in liquid (PUDEL) modifies anisotropic Co3O4 platelets by inducing lattice distortions and defects while enriching {111} surfaces with hydroxyl groups and tunes the catalytic activity of the Co3O4 platelets in electrocatalytic oxygen evolution and thermocatalytic selective oxidation reactions.

Mediated Futures in Anesthetic Space

open access: yesMedia Theory
Media are intimately connected to the future. They are simultaneously posited as encouraging speculation and foreclosing futures. Through an examination of the “canal craze” at the turn of the twentieth century in which the telescopic lens was believed ...

Regio‐ and Stereocontrolled‐Synthesis of a Heterocycle Fragment Collection Using Palladium Catalyzed C‐H Arylation

open access: yesChemistry – A European Journal, EarlyView.
44 novel heterocycle fragments are prepared through a C–H functionalization strategy. Systematic variation of exit vectors and polar functionality provides a set of fragments that sit in attractive fragment chemical space. Abstract Saturated heterocycles are valuable fragments in drug discovery due to their polarity, 3D structure, and potential for ...

Research on Telescope TTL Coupling Noise in Intersatellite Laser Interferometry

open access: yesPhotonic Sensors, 2019
The detection mission of gravitational waves in space is that the accuracy of the long-baseline intersatellite laser interferometry on the million-kilometer order needs to reach the order of $$8 \rm{pm}/\sqrt{\rm{Hz}}$$ 8 p m / H z .
