Simultaneously manipulating multiple physical fields plays an important role in the increasingly complex integrated systems, aerospace equipment, biochemical productions, etc.For on-chip systems with Decorating Tips high integration level, the precise and efficient control of the propagation of electromagnetic waves and heat fluxes simultaneously i
Organic vegetable farmers rely on intensive tillage to control weeds, incorporate amendments and residues, and prepare seedbeds.Intensive tillage, however, can lead to a decrease in long-term soil health.Placing opaque plastic tarps on the soil surface weeks or months before planting can reduce weed pressure and may facilitate organic reduced tilla
