High Capacity Draper Header – Development of a high capacity draper header for a new generation of combine harvesters

Ni1/3Co1/3Mn1/3(OH)2, a precursor of LiNi1/3Co1/3Mn1/3O2 in new-generation Li-ion batteries, was prepared by a hydroxide coprecipitation method. Scanning electronic microscopy (SEM) micrographs reveal that the precursor particles thus obtained, show regular shape with uniform size under optimized conditions. X-ray diffraction (XRD) indicates that well-ordered layer-structured LiNi1/3Co1/3Mn1/3O2 was prepared after calcination at high temperature. The final product exhibited a spherical morphology with uniform size distribution (10 μm in diameter). At the terminal charging voltage of 4.3 and 4.5 V (vs. Li/Li+), the testing cells of LiNi1/3Co1/3Mn1/3O2 delivered a specific capacity of 161.2 and 184.1 mAh g-1, respectively. The high capacity retention of 98.0 and 96.1 % after charging to 4.3 and 4.5 V for 50 cycles, respectively, indicates that this material displays excellent cycling stability even at high cut-off voltage.

This article discusses how the Tres Amigas SuperStation project will unite the long broken electrical grid system in the United States. The Tres Amigas SuperStation will be located in Clovis, NM, USA, close to large amounts of established and potential renewable generation. In its first phase, the project will support the 5000 MW of power transfer capacity. It will employ ultraefficient, high-capacity DC superconductor cables coupled with voltage-source converters in what will be, in essence, a superconductive electricity pipeline. SuperStation will make it practical, and economical, to “firm up” intermittent and variable renewable energy by taking advantage of geographical diversity and energy storage, such as the onsite batteries at Tres Amigas or systems such as compressed air energy storage. This capability greatly enhances the value of new generation, creating additional economic incentives for its development. Tres Amigas will also expand the geographic reach of markets, offering new opportunities to take advantage of load and resource diversity, which will reduce costs.

New Generation

: The stability profile of a new 1,4-dihydropyridine derivative (DHP), representative of a series with a hexahydroquinoline ring, was studied to design light-stable liquid formulations. This molecule, named M3, has been shown among the analogs to have a high capacity to block both L- and T-type calcium channels. The ethanol solution of the drug was subjected to a photodegradation test, in accordance with standard rules. The concentrations of the drug and its byproducts were estimated using multivariate curve resolution, applied to the spectral data collected during the test. The improvement of both the photostability and water solubility of M3 was investigated by adding the surfactant polysorbate 20 in a 1:5 ratio to aqueous solutions of the drug. These formulations were exposed to stressing light in containers of bleu polyethylene terephthalate (PET), amber PET, and covered amber PET. The best results were obtained when using the covered amber PET container, reaching a degradation percentage of the drug less than 5% after 12 h under an irradiance power of 450 W/m2. The stability of the compound was compared to that of nimodipine (NIM) under the same conditions.

New Generation

The new generation of capsules that circulate through vacuum tubes at speeds up to 1200 km/h, which is being developed, demands communication systems that can operate at these speeds with high capacity and quality of service. Currently, the two technologies available are the new generation of 802.11ax networks and 5G NR. Using these technologies at such high speeds in a confined environment requires a careful study and design of the configuration of the network and optimization of the physical interface. This paper describes the requirements for critical and business communications, proposing a WLAN and 5G network design based on the analysis of the propagation characteristics and constraints of vacuum tubes and using propagation measurements and simulations made in similar environments at frequencies of 2.5/5.7/24 GHz. These measurements and simulations show that propagation losses in this environment are low (4–5 dB/100 m), as a consequence of the guided propagation, so that the use of bands is preferred. Finally, considering the propagation constraints and requirements of a Hyperloop system, a complete wireless communication system is proposed using two networks with 802.11 and 5G technology.

Sodium Storage

AbstractRecently, abundant resources, low-cost sodium-ion batteries are deemed to the new-generation battery in the field of large-scale energy storage. Nevertheless, poor active reaction dynamics, dissolution of intermediates and electrolyte matching problems are significant challenges that need to be solved. Herein, dimensional gradient structure of sheet–tube–dots is constructed with CoSe2@CNTs–MXene. Gradient structure is conducive to fast migration of electrons and ions with the association of ether electrolyte. For half-cell, CoSe2@CNTs–MXene exhibits high initial coulomb efficiency (81.7%) and excellent cycling performance (400 mAh g−1 cycling for 200 times in 2 A g−1). Phase transformation pathway from crystalline CoSe2–Na2Se with Co and then amorphous CoSe2 in the discharge/charge process is also explored by in situ X-ray diffraction. Density functional theory study discloses the CoSe2@CNTs–MXene in ether electrolyte system which contributes to stable sodium storage performance owing to the strong adsorption force from hierarchical structure and weak interaction between electrolyte and electrode interface. For full cell, CoSe2@CNTs–MXene//Na3V2 (PO4)3/C full battery can also afford a competitively reversible capacity of 280 mAh g−1 over 50 cycles. Concisely, profiting from dimensional gradient structure and matched electrolyte of CoSe2@CNTs–MXene hold great application potential for stable sodium storage.
