Systematically Engineering for Efficient Production of 3‐Methyl‐1‐Butanol in Escherichia coli

open access: yesAdvanced Science, EarlyView.
An integrated metabolic engineering strategy was established for high‐level 3‐methyl‐1‐butanol biosynthesis in Escherichia coli. Molecular dynamics‐guided semi‐rational engineering of dihydroxyacid dehydratase uncovered and relieved key catalytic bottlenecks, while adaptive laboratory evolution enhanced strain robustness.

Non‐Equilibrium Synthesis Methods to Create Metastable and High‐Entropy Nanomaterials

open access: yesAdvanced Science, EarlyView.
ABSTRACT Stabilizing multiple elements within a single phase enables the creation of advanced materials with exceptional properties arising from their complex composition. However, under equilibrium conditions, the Hume–Rothery rules impose strict limitations on solid‐state miscibility, restricting combinations of elements with mismatched crystal ...

Dynamical system analysis of ignition phenomena using the tangential stretching rate concept [PDF]

open access: yes, 2015
We analyze ignition phenomena by resorting to the stretching rate concept formerly introduced in the study of dynamical systems. We construct a Tangential Stretching Rate (TSR) parameter by combining the concepts of stretching rate with the decomposition

Transition Metal Compounds for Aqueous Ammonium‐Ion Batteries: Storage Mechanisms and Electrode Design

open access: yesAdvanced Science, EarlyView.
Aqueous ammonium‐ion batteries leverage hydrogen‐bond‐mediated NH4+ storage in tunable transition metal compounds. Despite progress in Mn‐, V‐, Mo‐, and W‐based compounds, 2D LDHs, and MXenes, challenges like structural instability and slow kinetics persist. Future advances require robust host design, mechanistic understanding via operando studies, and

Reduced chemistry for butanol isomers at engine-relevant conditions

open access: yes, 2017
Butanol has received significant research attention as a second-generation biofuel in the past few years. In the present study, skeletal mechanisms for four butanol isomers were generated from two widely accepted, well-validated detailed chemical kinetic

Towards Climate Neutrality by 2050: Role of Aluminum for Short‐ and Long‐Term Energy and Hydrogen Storage

open access: yesAdvanced Energy Materials, EarlyView.
The Aluminum energy storage cycle involves the use of renewable energy for Al production and the generation of heat (dry cycle) and heat and H2 (wet cycle) for energy production via Al‐steam combustion. ABSTRACT Reaching climate neutrality by 2050 requires innovative long‐term energy storage (LTES) solutions beyond the current use of fossil fuels ...
