Summary: Spot fires caused by wind-carried firebrands are common in wildland-urban interface (WUI) fires. This study focused on firebrand deposition over cubic blocks in tandem and parallel arrangements, representing nearby small structures in the WUI. Large eddy simulations were used to model flow turbulence, while firebrands were simulated in the Lagrangian framework. The simulations revealed that the blocks protected their immediate leeward areas from firebrand deposition, creating safe zones in the shape of an isosceles trapezoid. The length of the safe zone increased with wind speeds, and upwind blocks also protected the lower part of the windward face of downwind blocks from firebrand deposition in certain cases.

Summary: This paper proposes a novel interface for metal oxide based gas sensors, utilizing a feedback-based thermal modulation method and an active digital control to maximize information collection from the sensors. By driving sensor operating temperature based on changes in sensor resistance, the proposed interface allows for real-time control over modulation parameters, enabling drift compensation, fault identification, and minimization of mutual information between sensors. Testing in lab calibration and practical scenarios showed better performance compared to standard thermal modulation techniques.

Summary: This study synthesizes titanium oxynitride (TiOxNy) through controlled step-annealing of commercial titanium nitride (TiN) powders in normal ambience. The resulting TiOxNy system inherits the surface plasmonic resonance (SPR) property of TiN, as confirmed by various analysis techniques. The TiOxNy system exhibits desirable prerequisites for enhanced photocatalytic activity, such as reduced band gap energy and enhanced carrier-lifetime. Under solar light irradiation, the TiOxNy photocatalyst shows efficient degradation of rhodamine B dye and production of H-2. The TiOxNy system functions via a plasmonic Ohmic interface due to its amalgamated band structures.
