Development and application of bond cleavage reactions in bioorthogonal chemistry

open access: yes, 2016
Bioorthogonal chemical reactions are a thriving area of chemical research in recent years as an unprecedented technique to dissect native biological processes through chemistry-enabled strategies. However, current concepts of bioorthogonal chemistry have

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Self-assembled dendrimer polyamide nanofilms with enhanced effective pore area for ion separation

open access: yesNature Communications
Membrane technology using well-defined pore structure can achieve high ion purity and recovery. However, fine-tuning the inner pore structure of the separation nanofilm to be uniform and enhance the effective pore area is still challenging.

A Facile Preparation of Palladium Nanoclusters Supported on Hydroxypropyl-β-Cyclodextrin Modified Fullerene [60] for Formic Acid Oxidation

open access: yesInternational Journal of Electrochemical Science, 2013
The use of fullerene [60] (C60) as carbon support material assists the dispersion of catalysts and provides new ways to develop advanced electrocatalyst materials as a result of its distorted structure.

Information extraction from chemical patents

open access: yes, 2011
The automated extraction of semantic chemical data from the existing literature is demonstrated. For reasons of copyright, the work is focused on the patent literature, though the methods are expected to apply equally to other areas of the chemical ...

Mapping the Space of Chemical Reactions using Attention-Based Neural Networks

open access: yes, 2020
Organic reactions are usually assigned to classes grouping reactions with similar reagents and mechanisms. Reaction classes facilitate communication of complex concepts and efficient navigation through chemical reaction space.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Beads‐on‐string hierarchical structured electrocatalysts for efficient oxygen reduction reaction

open access: yesCarbon Energy, 2023
Rational design of hierarchically structured electrocatalysts is particularly important for electrocatalytic oxygen reduction reaction (ORR). Here, ZIF‐67 crystals are stringed on core–shell Ag@C nanocables using a coordination‐modulated process.

Prediction of Chemical Reactions Using Statistical Models of Chemical Knowledge

open access: yes, 2018
Is chemistry discoverable or can it only be invented? – this is the question of a computer scientist and a philosopher of science when looking at application of artificial intelligence methods for developing new chemical entities and new chemical ...
