The main problem is less efficiency and blocking during sugarcane harvesting in hilly areas. This paper researched the cutting and transporting system of a small sugarcane harvester using virtual prototype technology. The dynamics simulation analyses were carried out to study the transporting status with different friction coefficients between the sugarcane and the spiral and different numbers ...

Low-cost and facile synthesis routes of hole-transporting materials (HTMs) are promising approaches to minimize the total cost perovskite solar cells (PSCs) on both laboratory commercial scales.

Abstract Single-walled carbon nanotubes (SWCNTs) are representative one-dimensional materials that show exceptional optical and electronic properties with various tuneable bandgaps. SWCNTs can be integrated into a variety of photovoltaics particularly, perovskite solar cells (PSCs) based on high level functionality purity. In this topical review, we discuss the fundamentals applied to PSCs as a...

The results of an experimental investigation of kerbside bridge deck drainage units are presented. The conveyance capacity, resistance coefficients and sediment transporting efficiencies of different types of drainage unit used in shallow bridge drainage decks are examined over a range of bed gradients likely to be encountered in practice. The use of a V-shaped cross section is shown to be part...

It is important to establish an appropriate transporting machine on the seafloor for deep ocean mining of cobalt-rich manganese crusts, as the physiognomy of cobalt-rich manganese crusts is complex and often varies. In view of the complexity of terrain of cobalt-rich manganese crusts and huge weight that need to be supported during ocean mining, a project of the six−legged walking robot driven ...

Perovskite solar cells fabricated from organometal halide light harvesters have captured significant attention due to their tremendously low device costs as well as unprecedented rapid progress on power conversion efficiency (PCE). A certified PCE of 20.1% was achieved in late 2014 following the first study of long-term stable all-solid-state perovskite solar cell with a PCE of 9.7% in 2012, sh...
