The homojunction of oxygen/metal vacancies and its interfacial n-p effect on the physiochemical properties are rarely reported. Interfacial homojunctions TiO2 fabricated by directly decorating p-type titanium-defected around n-type oxygen-defected nanocrystals in amorphous-anatase homogeneous nanostructures. Experimental measurements theoretical calculations cell lattice parameters show that oxygen titanium changes charge density ; a strong EPR signal caused an unreported 2D 1 H TQ-SQ MAS...
A core issue inherent to decision‐making and path‐planning tasks is managing the uncertainties in motion of dynamic obstacles. Therefore, this article proposes a new framework, based on game theory, that considers multistate future actions surrounding vehicles. First, neighboring vehicles, whose driving styles vary, are estimated fed into module for risk assessment. Then, Stackelberg ego vehicle rear object modeled as two players game, their optimal decisions obtained. In addition, model...

Two modified TiO2 nanofluids were developed, with either hydrophobic or hydrophilic properties. The nanofluid, embedded in an organo-silyl salt, could be transformed into a nanofluid by exchange of the chloride organo-sulphonate ion. Both exhibited high fluidity, thermal stability and photoactivity.
A rapid urea and byproduct deposit experimental platform was built an integrated after-treatment device model of the nonroad agricultural diesel engine established based on CONVERGE software. The effects exhaust temperature, flow rate, injection mass deposits were studied by both experiments simulation. validated using back pressures catalysts, mixer wall distribution deposits. performance evaluated concentration, mass, uniformity NH3 at front-end cross-section its selective catalytic...
An integrated after-treatment device model was established for our target engine based on the fluid simulation software (Converge), and performed to determine NH3, temperature, velocity uniformity at front-end cross section of its SCR catalyst, urea deposition rate, liquid film mass mixer, positions under a low-load condition. Moreover, structure mixer injection pressure were optimized improve reduce mass. Our results show following facts: is easily accumulated condition significantly affect...
Thermoelectric technology improves engine energy efficiency by recovering waste heat from the exhaust gases of internal combustion engines. Compared to a conventional Generator (TEG), TEG integration in aftertreatment can improve power generation and reduce impact on back pressure. In current study, three-dimensional numerical model based an integrated for diesel engines is proposed first time related research carried out using simulation. The results show that temperatures gas compositions...
In article number 1802173, Xiao-Yu Yang and co-workers present a junction of oxygen titanium vacancies at the amorphous–anatase interface nanostructured TiO2 for creating what chaos theory describes as network fabric, which results in unique n–p electronic transmission contributes to significant performance photogeneration current, photocatalysis, energy storage. It sheds new light on fundamental aspects semiconductor nature.
During the active regeneration process, engine speed may drop to idle (DTI) under extreme circumstances, where diesel particulate filter (DPF) is subjected severe thermal stress that can cause DPF cracks. To prevent damage, this study investigated temperature variation of silicon carbide (SiC) substrate with different vehicle speed, initial soot load, duration and target DTI real road conditions . The results showed peak gradient were greatly increased at rear end DPF. radial distribution in...
As emission regulations become increasingly stringent, the durability of diesel aftertreatment system is another concern in addition to excellent purification capacity. Under extreme circumstances, engine may drop idle (DTI) sharply and if active regeneration occurs during this period, there a risk DPF cracking melting due huge accumulation soot combustion heat. In study, performances, including temperature transient characteristics cordierite DTI process were investigated. The distribution...
