“…Compared with a simple physical mechanical mixing synthesis method, the in-situ synthesis method for the as-prepared catalysis displays a more uniform structure. Moreover, this in-situ synthesis method provides a strategy for forming a tight-contact heterostructure between two compounds [61]. From the eco-friendly and chemical stability view, tin oxide (SnO2) was employed as a promising photocatalyst [62].…”

“…It can be seen that the influence of three different contact modes of silicon and coating on the electrochemical performance of silicon anode should be drowned more attention. Although there have been some researches focusing on material design, [ 28,19 ] surface and interface engineering, [ 67,68 ] structural design, [ 69,70 ] mechanism research, [ 71,72 ] and composite and coating engineering with carbon materials, [ 73,74 ] the influence of contact engineering between core and coating on the performance of silicon anode has not been systematically summarized. Based on this, this review will start from the contact engineering according to the three contact modes of F2F, L2L and P2P, detail its influence on ion/electron transfer and electrochemical performance of silicon anode, and summarize the structural design direction which is conducive to improve the performance of silicon anode for the reference to researchers.…”

Silicon is considered as the desirable anode material for lithium‐ion batteries due to its suitable discharge potential, abundant reserve, and ultra‐high specific capacity. However, poor conductivity and unstable battery performance caused by large volume change during cycling limit the further development of silicon anode. In order to avoid the unstable solid electrolyte interface layer caused by the direct contact between silicon and electrolyte, and to eliminate the structural collapse caused by the volume change during cycling, dimension size reduction, reserved voids, and novel structural framework are usually adopted. Although these methods can effectively improve the defects, a new problem is introduced and cannot be ignored: contact engineering between the coating layer and silicon core. Herein, contact engineering is classified into three categories: face to face (F2F), line to line (L2L), and point to point (P2P) according to the contact modes between the coating and core. There is utilizability of the structure categories of different contact modes and their influence on electrochemical performance. Therefore, in the future research of silicon anode, contact engineering is a non‐negligible aspect in the structural design process. Finally, feasible strategies based on contact engineering have been indicated.

“…For the selected electric motor, the different types of commercial batteries available were taken into account: Acid lead, NiMH, NiCd, LiPo, and LiFePO4, although new materials for batteries in aerospace and aeronautical applications will be available in the coming years [79][80][81]. However, with the actual state of technology and market prices, it was concluded that the best battery to be used in the electric ALO is the lithium polymer (LiPo) battery.…”

It is well proved that remotely piloted aircraft systems (RPASs) are very useful systems for remote sensing in precision agricultural labors. INTA (National Institute for Aerospace Applications) and the University of Huelva are involved in Tecnolivo Project that proposes the development of a marketable and easy-to-use technological solution that allows integrated, ecological, and optimized management of the olive grove through non-invasive monitoring of key agronomic parameters using RPASs. The information collected by the RPAS in regards to the state of the vegetation, such as hydric stress levels, plague detection, or maturation of the fruit, are very interesting for farmers when it comes to make decisions about their crops. Current RPAS applications for precision agriculture are mainly developed for small- to medium-sized crops using rotary-wing RPASs with small range and endurance operation, leaving aside large-sized crops. This work shows the conversion of a fully declassified and obsolete fixed-wing internal combustion engine (ICE) remotely piloted aircraft (RPA), used as aerial target for military applications and in reconnaissance and surveillance missions at low cost, into an electric lithium polymer (LiPo) battery-driven RPA that will be used for precision agriculture in large-sized crop applications, as well as other applications for tracking and monitoring of endangered animal species in national parks. This RPA, being over twenty years old, has undergone a deep change. The applied methodology consisted of the design of a new propulsion system, based on an electric motor and batteries, maintaining the main airworthiness characteristics of the aircraft. Some other novelties achieved in this study were: (1) Change to a more efficient engine, less heavy and bulky, with a greater ratio of torque vs. size. Modernization of the fly control system and geolocation system. (2) Modification of the type and material of the propeller, reaching a higher performance. (3) Replacement of a polluting fuel, such as gasoline, with electricity from renewable sources. (4) Development of a new control software, etc. Preliminary results indicate that the endurance achieved with the new energy and propulsion systems and the payload weight available in the RPA meet the expectations of the use of this type of RPAS in the study of large areas of crops and surveillance.
