A Cholesterol Analogue for Cell‐Surface Enzyme Display

open access: yesAngewandte Chemie, EarlyView.
We report a non‐genetic strategy for bacterial cell surface enzyme immobilisation using cholesterol‐based artificial lipids containing Ni2+‐NTA binding groups that can integrate into biological membranes. The engineered cells can capture His‐tagged enzymes directly from cell lysates while preserving intracellular and surface activity, allowing for ...

Validation of a German version of the Boredom Proneness Scale and the Multidimensional State Boredom Scale

open access: yesScientific Reports
The scientific interest in boredom is growing over the past decades. Boredom has not only been linked to symptoms of psychopathology, but also shows a remarkable effect on individual behavior under healthy conditions. Current characterizations of boredom

Thermally Assisted Photocatalytic Dehydrogenation of Methanol in Continuous Steady‐State Operation

open access: yesAdvanced Science, EarlyView.
Thermally assisted photocatalytic methanol dehydrogenation on Pt/TiO2 enables formaldehyde and hydrogen production far beyond thermodynamic limits. Continuous operation delivers up to 95% selectivity over 70 h, and oxygen microdosing strongly boosts conversion by regenerating surface oxygen sites.

Chemoenzymatic Synthesis of Heparan Sulfate Oligosaccharides by a Covalent Catch‐and‐Release Approach

open access: yesAngewandte Chemie, EarlyView.
A glycan having a hydrazide tag enables chemoenzymatic synthesis of HS oligosaccharides. The hydrazide can, under mild acidic conditions, react with an aldehyde‐containing resin to give an immobilized hydrazone that is stable under neutral conditions, allowing washing. The product can be released by transiminolysis using aqueous hydroxylamine to give a

Is Youth's Engagement in Agribusiness an Opportunity or a Necessity? A Closer Look at the Situation in South Kivu, Eastern Democratic Republic of the Congo

open access: yesAgribusiness, EarlyView.
ABSTRACT Despite the broad focus on necessity‐ and opportunity‐driven entrepreneurship in research and policy, the entrepreneurial dichotomy within the agribusiness context has not been adequately addressed. This study contributes to closing this knowledge gap by examining youth's perceptions of agribusiness through the lens of the push‐pull motivation

Pd/C‐Catalyzed Hydrogenation of CF3‐, CF2H‐, and CF2CO2Et‐containing Pyridines: A Robust Method for Highly Functionalized containing Piperidines

open access: yesAngewandte Chemie, EarlyView.
A robust and efficient method to access diversely functionalized fluorinated piperidines was developed. The approach features the hydrogenation of polysubstituted pyridines bearing CF3, CF2H, and CF2CO2Et substituents using an inexpensive, readily available heterogeneous Pd/C catalyst under air‐ and moisture‐tolerant conditions, offering an appealing ...

GraphRAG for engineering diagrams: ChatP&ID enables LLM interaction with P&IDs

open access: yesAIChE Journal, EarlyView.
Abstract Piping and Instrumentation Diagrams (P&IDs) are central to process engineering workflows, yet extracting information from them remains a tedious and time‐consuming task. This work introduces ChatP&ID, a framework enabling natural‐language interaction with smart P&IDs through Graph Retrieval‐Augmented Generation (GraphRAG), to our knowledge ...

Enhancing Enzyme Activity With Mutation Combinations Guided by Few‐Shot Learning and Causal Inference

open access: yesAngewandte Chemie, EarlyView.
We present an integrated workflow that predicts activity‐enhancing mutation combinations from minimal experimental data. By proposing in vivo unit yield (yield/expression) as a surrogate for kcat/Km through causal inference, and visualizing local activity landscape, it effectively guides product yield improvement. ABSTRACT Designing enzyme sequences to
