Deposition technology of transparent conducting oxide (TCO) thin films is critical for high performance optoelectronic devices. Solution-based fabrication methods can result in substantial cost reduction and enable broad applicability the TCO films. Here we report a simple highly effective solution process to fabricate indium-tin (ITO) with uniformity, reproducibility, scalability. The ITO are (90.2%) conductive (ρ = 7.2 × 10(-4) Ω·cm) highest figure merit (1.19 10(-2) Ω(-1)) among all...

The five-level active neutral-point-clamped (5L-ANPC) converter is becoming an attractive topology of multilevel family. A novel SVPWM algorithm based on line voltage coordinate was studied in this paper to overcome shortcomings the traditional algorithm. Through transformation, steps determining basic vectors and solution about vector corresponding action time are simplified. Combining with characteristics 5L-ANPC new control algorithm, a method controlling balancing dc-link capacitors...

Synthetic microbial consortia represent a new frontier for synthetic biology given that they can solve more complex problems than monocultures. However, most attempts to co-cultivate these artificial communities fail because of the winner-takes-all in nutrients competition. In soil, multiple species coexist with spatial organization. Inspired by nature, here we show an engineered segregation method assemble stable both flexibility and precision. We create swarmbot (MSBC) encapsulating...

Since industrialization, global temperatures have continued to rise. Human activities resulted in heavy metals being freed from their original, fixed locations. Because of warming, glaciers are melting, carbon dioxide concentrations increasing, weather patterns shifting, and various environmental forces at play, resulting the movement alteration forms. In this general context, impact on ecosystems organisms has changed accordingly. For most ecosystems, levels rise, rise can a negative...
