p-Hydroxybenzyl alcohol (HBA) is one of phenolic compounds in herbal agents and plays a pivotal role protection against oxidative damage-related diseases due to anti-inflammatory effects. We have developed new biodegradable peroxalate copolymer which HBA chemically incorporated into its backbone. The HBA-incorporated copolyoxalate (HPOX) was synthesized from condensation reaction oxalyl chloride, 1,4-cyclohexamethanol capable releasing pharmaceutically active during hydrolytic degradation....
This study introduces a cutting-edge electrolyte formulation that mitigates Li metal corrosion, significantly extending the calendar life of LMBs. Based on SEI swelling model, hydrocarbons kinetically block highly corrosive F-diluent entry.
The development of highly efficient Ru-based catalysts for NH3 decomposition is necessary to enable the utilization as a COx-free H2 carrier. Modulation interactions between basic support materials and Ru particles significantly enhances performance decomposition. In this study, strong metal–support interaction (SMSI) interface BaCeO3 perovskite was controlled by yttrium (Y) doping in range 0–20 mol %. substitution Y3+ into Ce4+ sites improved reducibility removal lattice oxygen atoms, which...
Typically, to meet emission regulations, the selective catalytic reduction of NOX with NH3 (NH3-SCR) technology cause emissions owing high NH3/NOX ratios regulations. In this study, V-Cu/BN-Ti was used remove residual and NH3. Catalysts were evaluated for oxidation (NH3-SCO) in NH3-SCR reaction at 200-300 °C. The addition vanadium copper increased number Brønsted Lewis acid sites available by increasing ratio V5+ forming Cu+ species, respectively. Furthermore, h-BN dispersed catalyst improve...
Ribbons may be used for the modeling of DNAs and proteins.The topology a ribbon can described by link Lk, while its geometry is represented writhe Wr twist Tw.These three quantities are numerical integrals related single formula from knot theory.This article discusses meanings these quantities, offers an approach calculating their values, provides some examples.
Herein, we report the effect of using nanoparticles LiFePO4 on electrochemical properties all-solid-state batteries (ASSBs) with a solid electrolyte. (LFP) cathode materials are promising in polymer-based composite electrolytes because their limited window range. However, LFP cathodes exhibit poor electric conductivity and sluggish lithium ion diffusion. In addition, there is disadvantage that interfacial resistance increases due to contact between material electrolyte when composing...
In order to study the frictional behavior of a roller linear motion guide (RLMG) in mixed elastohydrodynamic lubrication (EHL), micro–macro contact analysis is employed analyze parameters at surface, such as load and deformation, shear stress due sliding effect, lubricant. Then friction model developed via combination local with analysis. The effectiveness was validated by experimental results. Stribeck RLMG analyzed detail. Furthermore, effects geometrical operating conditions on are...
3D printing allows for the cost-effective fabrication of moulds and can cast complex shapes. In this study, alumina cement fine aggregates refractories were used as main raw materials, saturation was adjusted to an appropriate level control binder mixture sand casting. For iron, mould must withstand temperatures up 1400 °C exhibit sufficient strength, gas permeability, thermochemical durability at high temperatures. To accomplish these requirements, powder prepared by adjusting ratio...
Layered NaV3O8 was prepared by solid-state reaction at 400°C and the phase confirmed Synchrotron XRD. The FE-SEM BET studies revealed plate-type morphologies of micrometer-sized particles with surface area 7 m2 g−1. When tested for Na-ion insertion properties, cathode registered reversible discharge capacities 90 mAh g−1 (100% theoretical value) a well-defined plateau around 2.5 V decent capacity retentions 0.16 C current density. impressive retention 61% initial 10.2 densities attributed to...
This letter proposes a high precision ranging scheme based on the time of arrival estimation technique for IEEE 802.15.4a chirp spread spectrum system. The proposed consists linear channel impulse response process with zero forcing or minimum mean square error and multipath delay matrix pencil algorithm. performance is compared that well known MUSIC algorithm in terms computational complexity precision. Simulation results demonstrate outperforms even though it has comparatively lower complexity.
