The agriculture sector is currently facing the problems of aging and decreasing skilled labor, meaning that future direction will be a transition to automation mechanization can maximize efficiency decrease costs. Moreover, interest in development autonomous agricultural vehicles increasing due advances sensor technology information communication (ICT). Therefore, an driving control algorithm using low-cost global navigation satellite system (GNSS)-real-time kinematic (RTK) module motion was...
Sorting and quantification of deactivated bacteria is an important way quality control for whole-cell bacterial vaccines. In general, surface features used vaccines affect the immunoresponse to bacteria-associated antigens. Enumeration also process development parameter these Field-flow fractionation (FFF) was previously applied separation bacteria. For first time, FFF sorting strains same species on basis differences in membrane characteristics. Two techniques, gravitational (GrFFF)...

In this study, simulation tests for gravity gradient referenced navigation (GGRN) are conducted to verify the effects of various factors such as database (DB) and sensor errors, flight altitude, DB resolution, initial measurement update rates on performance. Based results, requirements GGRN established position determination with certain target accuracies. It is found that errors altitude have strong particular, a accuracies 0.1 E 0.01 E, respectively, required determine more accurately than...
For many years traditional 193i lithography has been extended to the next technology node by means of multi-patterning techniques. However recently such a became challenging and expensive push beyond for complex features that can be tackled in simpler manner Extreme UltraViolet Lithography (EUVL) technology. Nowadays, EUVL is part high-volume manufacturing device landscape it reached critical decision point where one further single print on 0.33NA full field scanner or move EUV double...
Abstract Nanocrystals of Cs 3 Cu 2 I 5 , a metal halide with promising potential as perovskite substitute, are successfully grown on graphene nanosheets. An intermediate stage physically exfoliated nanosheets, concurrent the formation copper‐based seeds surface, is developed, for first time, allowing subsequent growth nanocrystals (CsNCs) to obtain CsNCs‐decorated nanohybrids (CsGNHs). The morphology and properties CsGNHs depend input amount nanosheets during reaction. photoluminescence...
Herein, we demonstrate a facile ligand-mediated hot injection strategy for manipulating the growth of Cs3Cu2Br5 nanocrystals to systematically control their morphology and properties. The use ligands with different chain lengths (C6, C9, C18) resulted in morphologies. All exhibited large band gaps, optical absorption spectra depended on morphology. Furthermore, demonstrated that photoluminescence can be modulated by replacing halogen atom Br I or Cl. electronegativity was correlated...
The variously shaped gold patterns can be generated from the polydimethylsiloxane (PDMS) mold using line by capillary force lithography (CFL) process, which is a kind of nanoimprint method following two-cycle method. After fabrication micro- or nanosized at first cycle, patterned substrate used as for second cycle CFL. When other stamp placed on pattern, rotated certain angle with respect to stamp, only overlapped parts remained dot-shaped after etching process. various shapes and sizes...

Research effort has increasingly been devoted to exploiting efficient noble-metal-free electrocatalysts because of their low cost and abundancy. Herein, metallic nanoparticulate-containing carbon nanofibers (MCNFs) featuring interior, nanoparticulate-in-pore structures were fabricated by taking advantage cationic metal species/anionic surfactant complexes (MSCs). Binary MSC mixtures containing Fe–Co, Fe–Ni, Co–Ni species used control not only the size/loading amount phases but also...
The crystallization of nanocrystal building blocks into artificial superlattices has emerged as an efficient approach for tailoring the nanoscale properties and functionalities novel devices.
