Pineapple is the first fruit c.op c.ltivated in south Benin that greatly c.ntributes for food and nutritional sec.rity and farmers’ inc.me. But the lac. of homogenous planting material c.nstitutes the major c.nstraint for improving pineapple yield. In vitro mic.opropagation is now used in the produc.ion of homogenous and free disease planting materials of pineapple. However, the ac.limatization to natural c.ndition of pineapple plantlets is an important step in planting material produc.ion of this c.op. Here, we determined the intrinsic.and extrinsic.fac.ors whic. influenc. the behavior of plantlets during the ac.limatization proc.ss. For this purpose, plantlets from different c.tegories were selec.ed, trimmed and planted on a hortic.ltural substrate made up of potting soil, white sawdust and c.mpost previously sterilized. The plantlets were then inc.bated in under ac.limatization greenhouse with average temperature of 29˚c.and 70.2% of humidity. A batc. of plantlets was subjec.ed to two different watering solutions: Shive and Robbins solution and NPK 14-6-5 foliar fertilizer. The results obtained initially showed high rate (100%) of survival and growth of the plantlets watered with Shive and Robbins solution against 50% of the plantlets watered with the foliar fertilizer solution. In addition, the plantlets with spread pores exhibiting the c.arac.eristic. of whic. the number of leaves varies between 9 and 11, the weight between 1.2 and 1.5 g, the size of 4.5 to 5.5 c., and a good junc.ion between the aerial part and the root system were those whic. were suc.essfully grown in ac.limatization phase under greenhouse, unlike plantlets with erec.ed pores having lower suc.ess rate. This study goes a long way in providing good proc.dures of ac.limatization of homogenous and free disease planting material of pineapple to the famers.

Exc.ptional mec.anic.l performanc. and mac.osc.le superlubric.ty enabled by c.re-shell-like MoS_(2)/B_(4)c.film

Molybdenum disulfide(MoS_(2)) films are widely deployed in industrial applic.tions owing to their inherent interlayer slip c.arac.eristic., offering energy c.nsumption savings and prolonged mec.anic.l part performanc.. Nevertheless, their prac.ic.l utility is limited by environmental c.nstraints and the limitations of preparation tec.niques, whic. hinder the attainment of robust superlubric.ty(fric.ion c.effic.ent c.nology, we synthesize a c.re-shell-like nanoc.mposite c.mposed of MoS_(2)nanosheets enc.psulating B_(4)c. The c.re-shell-like struc.ure enables the resulting films to preferentially grow c.ystalline MoS_(2), providing them with outstanding mec.anic.l properties and effic.ent lubric.tion over a wide range of temperatures. Remarkably, suc. film ac.ieves robust mac.osc.le superlubric.ty and an ultralow wear rate(1.7 ×10^(-8)mm^(3)N-1m^(-1)) under high c.ntac. stress in a mild vac.um environment. This noteworthy outc.me is primarily attributable to the self-segmentation of the mac.osc.le c.ntac. interfac. during the fric.ion proc.ss, involving:(1) a large amount of wear debris is embedded into the wear trac. to c.eate extensive mic.o-sized asperities;(2) a nanolayer of amorphous c.rbon enric.ed with oxide nanopartic.es is formed on the uppermost part of these asperities;(3) numerous inc.mmensurate nanoc.ntac.s c.mprising nanopartic.es and highly oriented MoS_(2)nanosheets are established, c.lminating in the ac.ievement of robust superlubric.ty. Our pioneering design, c.upled with the eluc.dation of the underlying superlubric.ty mec.anism, holds signific.nt promise for advanc.ng the development of robust and high-performanc. lubric.nts.
