Atomic layer deposition (ALD) combined with self-assembled monolayer (SAM) passivation allows selective deposition on patterned substrates at the nanoscale, enabling bottom-up material fabrication for various applications. Selective chemisorption of 1-octadecanethiol (ODT) on Cu over SiO2 is exploited to achieve area selective deposition (ASD). Alt...

A new organocatalyzed fluoride metathesis reaction between fluoroarenes and carbonyl derivatives is reported. The reaction exchanges fluoride (F–) and alternate nucleophiles (OAc–, OCO2R–, SR–, Cl–, CN–, NCS–). The approach provides a conceptually novel route to manipulate the fluorine content of organic molecules. When the fluorination and defluor...
Many West-European forests are located on degraded and acidified soils. Soil acidification has resulted in hampered ecosystem functioning and lower delivery of ecosystem services. Forest management, particularly the choice of tree species, can accelerate or counteract soil acidification by the quality of litter input. The positive impact of so call...
Aflatoxins as toxic substances produced by microorganisms widely existed in food crops and detoxification of aflatoxins is highly desired to avoid their leaking into the environment. Herein, a novel combination strategy of metal organic frameworks (MOFs) and porous membrane was used to prepare membrane adsorbent for aflatoxin B1 (AFB1) removal. Fir...

To develop catalysts with superior stability for isobutane alkylation, La3+ exchanged FAU zeolites with varying framework Si/Al ratios were investigated. Based on the reaction performed in a continuous flow stirred tank reactor, a strong linear relationship between catalyst lifetime and strong Bronsted acid concentration was observed. Catalyst life...

Naturally occurring spatiotemporal patterns typically have a predictable pattern design and are reproducible over several cycles. However, the patterns obtained from artificially designed out-of-equilibrium chemical oscillating networks (such as the Belousov-Zhabotinsky reaction for example) are unpredictable and difficult to control spatiotemporal...
Herein, we report a novel porphyrin/fullerene supramolecular cocrystal using a shape-persistent zinc-metalated porphyrin box (Zn-PB) and C-60/C-70. An unprecedented arrangement of a tightly packed square-planar core of four C-60 or C-70 surrounded by six cube-shaped Zn-PBs was observed. This unique packing promotes strong charge transfer (CT) inter...
