Impact of the Flame-Holder Heat-Transfer Characteristics on the Onset of Combustion Instability [PDF]

open access: yes, 2013
In this article, we investigate the impact of heat transfer between the flame and the flame-holder on the dynamic stability characteristics of a 50-kW backward-facing step combustor. We conducted a series of tests where two backward step blocks were used,

Hierarchical Strain‐Modified Medium‐Entropy Carbide Ceramics Exhibit Exceptional Ablation Resistance up to 2400°C

open access: yesAdvanced Science, EarlyView.
A novel strategy is developed by doping reduced graphene oxide (rGO) into a (HfZrTi)C medium‐entropy ceramic. This induces a hierarchical strain modification mechanism, synergistically inhibiting crack propagation at the microscale and dissipating stress at the mesoscale.

Programming Next‐Generation Synthetic Biosensors by Genetic Circuit Design

open access: yesAdvanced Science, EarlyView.
Synthetic biology enables genetic circuit‐based biosensing to detect diverse targets, process signals, and transduce them into readable outputs or intracellular regulatory activities. However, field deployment and real‐world application of such synthetic biosensors face considerable challenges in sensitivity, specificity, speed, stability, and ...

Precise Tailoring of Charge Transport Characteristics in Zr and Hf Doped Indium Tin Oxide Thin Film Transistors

open access: yesAdvanced Electronic Materials, EarlyView.
Zirconium, hafnium, and mixed zirconium/hafnium doped indium tin oxide thin films are accessible by atomic layer deposition. The amorphous functional films are about 8 nm thick and show a high interdiffusion of all elements. Their transistor characteristics can be modulated depending on the amount of Zr and Hf oxide phases incorporated in these thin ...

Poly(Vinylidene Fluoride)‐Wrapped LiFePO4 Microspheres as Highly Stable Dual Functional Cathode for Solid‐State Lithium Batteries

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
A dual functional cathode is made by uniformly dispersing the cathode material (LiFePO4) into the polymer electrolyte poly(vinylidenfluorid‐co‐hexafluorpropylene):lithium bis(trifluoromethanesulfonyl)imide, resulting in a conformable lamella structure with embedded microspheres.
