Lightweight and High‐Strength Carbon Bulk Preparation Via Low‐Temperature Pressureless Sintering of Sugar‐Derived Carbon

Advanced Science, EarlyView.
The synergistic effect between crosslinked polyacrylamide and glucose brings the precursor sintering activity with better thermostability, allowing its formation of a coherent carbon structure at lower temperatures (≤ 1200 °C) under ambient pressure.

Stereodivergent Synthesis of Three Contiguous Stereogenic Centers by Cu/Ir‐Catalyzed Borylallylation

Angewandte Chemie, EarlyView.
An alkene borylallylation strategy enabled by cooperative Cu/Ir‐catalysis has been uncovered for accessing three contiguous stereogenic centres. This strategy is notable given the inherent challenges of constructing molecules with multiple stereocenters while maintaining high selectivity bearing diverse functional groups.

Furan and alkylated furans in heat processed food, including home cooked products

Czech Journal of Food Sciences, 2014
The occurrence of furan in home cooked food was studied. Cooking was found to reduce the level of furan in ready-to-eat foods, however on average around 50% of furan remain in the foods.

Clickable Microgel Inks Enable Spatioselective, Multi‐Stimuli Programmable Assembly of Materials

Advanced Science, EarlyView.
Clickable microgel inks enable direct ink writing of hydrogel architectures with intrinsic spatioselective and programmable multi‐responsiveness. By combining pH‐responsive and temperature‐responsive microgel building blocks through Diels‐Alder interparticle crosslinking, the assemblies exhibit controllable swelling and shape changes.

Expanding the Chemical Space of Cyclic Polyphthalaldehyde via Post‐Functionalization

Advanced Science, EarlyView.
In this work, we developed a post‐functionalization approach to achieve water‐soluble cyclic polyphthalaldehyde (cPPA) polymers via click chemistry. ABSTRACT Cyclic polyphthalaldehydes (cPPAs) are hydrophobic cyclic polymers with stimuli‐responsive depolymerization property. The introduction of hydrophilic functionalities to cPPAs is challenging due to

Thermoelectric Properties of a Family of Benzodifuranone‐Based Conjugated Copolymers in Oriented Thin Films Doped Sequentially With NDMBI‐H

Advanced Electronic Materials, EarlyView.
Combining high polymer orientation of n‐type copolymers by temperature rubbing and sequential doping with N‐DMBI results in a strong improvement of electrical conductivity and thermoelectric power factors reaching up to 9.8 ± 1.6 S cm−1 and 8 ± 3 µW m−1.K2, respectively.

Hierarchical Zeolites Prepared Using a Surfactant-Mediated Strategy: ZSM-5 vs. Y as Catalysts for Friedel–Crafts Acylation Reaction

Molecules
Hierarchical ZSM5 and Y zeolites were prepared through a surfactant-mediated strategy with NH4OH changing the duration of the treatment and the amount of CTAB surfactant and taking as reference multiples of the critical micellar concentration (CMC).
