Analysis of auto-ignition of heated hydrogen-air mixtures with different detailed reaction mechanisms [PDF]
, 2011 Auto-ignition processes of hydrogen, diluted with nitrogen, in heated air are numerically investigated by means of an unsteady laminar flamelet approach in mixture fraction space. The focus is on the auto-ignition delay time and the most reactive mixture

Advanced Science, EarlyView.A Stringent dUPlex‐activated Error Robust (SUPER) DNAzyme system enables real‐time imaging of alternative mRNA splicing (e.g., Bcl‐xL/Bcl‐xS) in living cells via target‐triggered split‐DNAzyme reassembly and dual‐color fluorescence. It also achieves mRNA‐selective knockdown through DNAzyme‐based gene regulation, serving as a versatile tool for splicing

Quantifying "Cliffs" in Design Space
, 2014 This paper studies the regions of parameter space of engineering design in which performance is sensitive to design parameters. Some of these parameters (for example, the dimensions and compositions of components) constitute the design, but others are ...

Optical study of flow and combustion in an HCCI engine with negative valve overlap [PDF]
, 2006 One of the most widely used methods to enable Homogeneous Charge Compression Ignition (HCCI) combustion is using negative valve overlapping to trap a sufficient quantity of hot residual gas. The characteristics of air motion with specially designed valve

Origins of Graphite Resistivity: Decoupling Stacking Fault and Rotational Misorientation
Advanced Science, EarlyView.Interfacial dislocations critically influence interlayer transport in van der Waals (vdW) materials, yet quantifying their individual contributions remains challenging. We measure graphite's c‐axis resistivity and develop a decoupling strategy, revealing a resistivity ratio of ∼4507:74:1 for rotational misorientations, stacking faults, and AB stacking,
