Aluminum textile-based binder-free nanostructured battery cathodes using a layer-by-layer assembly of metal/metal oxide nanoparticles
No full textDespite considerable interest in textile-based battery electrodes with large surface areas and mechanical flexibility, issues have restricted further advances in the energy performance of textile electrodes. These issues include the ineffective incorporation of conductive and/or active components into textile frameworks, the poor charge transfer between energy materials, and the formation of numerous unstable interfaces within textile electrodes. Herein, we introduce an aluminum textile-based lithium-ion battery cathode with remarkable areal capacity, high rate performance, and good cycling stability. Ligand exchange reaction-induced layer-by-layer (LbL) assembly of metal nanoparticles and small molecule linkers, with subsequent metal electroplating, perfectly converted polyester textiles to 3D-porous aluminum textiles that can be used as current collectors and high-energy reservoirs. The consecutive LbL assembly of high-energy LiFePO4 and conductive indium tin oxide nanoparticles onto the aluminum textiles using small organic linkers significantly increased the areal capacity and cycling stability (at least 580 cycles) of the resultant cathode, allowing facile charge transfer within the textile electrodes. Furthermore, the areal capacity of these textile electrodes increased from 1.07 to 3.28 mA h cm-2, with an increase in the folding number from 0 to 2. © 2021 Author(s).1
Marketing Innovation
No full text"This paper provides an economic analysis of marketing innovation. A dynamic duopoly model is developed to study two forms of marketing innovation: Gamma, which allows a firm to acquire consumer information effectively; and sigma, which reduces consumer transaction costs. The incentives and effects of marketing innovation differ markedly from those of product or process innovations. Although Gamma benefits the innovating firm, it hurts some consumers; and, while sigma benefits all consumers, it may or may not benefit the innovating firm. Increased competition intensity reduces the value of Gamma but increases the value of sigma. The private incentive is too high for Gamma but too low for sigma."

Price and Variety in the Spokes Model
No full textThe spokes model of nonlocalised spatial competition provides a new analytical tool for differentiated oligopoly and a representation of spatial monopolistic competition. An increase in the number of firms leads to lower equilibrium prices when consumers have relatively high product valuations, but, surprisingly, to higher equilibrium prices for intermediate consumer valuations. New entry alters consumer and social welfare through price, market expansion, and matching effects. With free entry, the market may provide too many or too few varieties from a social welfare perspective, and the equilibrium price remains above marginal cost even when the number of firms is arbitrarily large.

No full textSelectfluor-mediated oxidative methylenation of amide with N,N-dimethylpropanamide for N,N’-methylenebisamide synthesis
No full textA simple and efficient approach for the synthesis of N,N'-methylenebisamides through a Selectfluor-mediated oxidative reaction of aromatic amides and N,N-dimethylpropanamide (DMP) is described. Remarkable results clearly reveal that DMP plays a dual role in this reaction, as both a one-carbon source and an environment-friendly solvent. Moreover, the process provides new strategies for the synthesis of bisamides with advantages of operationally simple, insensitive to atmospheric conditions and good to high yields.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

Effect of dietary inclusion of Achyranthes japonica extract on growth performance, fecal microbiota, fecal gas emission, nutrient digestibility, and meat-carcass grade quality traits in finishing pigs
No full textA ten-week experimental trial was carried out to determine the effect of - dietary inclusion of Achyranthes japonica extract (AJE) on finishing pigs overall performance. A total of 150 finishing pigs with initial body weight (BW) of 54.17 2.27 kg were randomly allocated to 5 dietary treatments. The dietary treatments were CON (Basal diet), TRT1 (Basal diet + 0.025% AJE), TRT2 (Basal diet + 0.05% AJE), TRT3 (Basal diet + 0.1% AJE), TRT4 (Basal diet + 0.2% AJE). Dietary AJE supplementation linearly increased BW, average daily gain (ADG), and gain to feed ratio (G:F) during week 5. At week 10 and overall experiment, there was tendency for linear increase in BW, ADG and ADFI. Dietary supplementation of AJE failed to show significant effects on nutrient digestibility, fecal microbiota, meat quality, and fecal gas emission. The dietary supplementation of AJE showed a linear increase in the backfat thickness at week 10 and there was no significant difference observed on the lean meat percentage. In summary, Achyranthes japonica extract supplementation diet had a beneficial effect on the growth performance and backfat thickness and also no effects on nutrient digestibility and fecal microbiota of the finishing pigs.The presentation of the authors' names and (or) special characters in the title of the pdf file of the accepted manuscript may differ slightly from what is displayed on the item page.

Reforming tax expenditure programs in Poland
No full textPoland has recently begun reforming its tax program. In December 1999 it announced a gradual reduction in the corporate income tax rate, from 34 percent in 1999 to 22 percent in 2004. Value added and excise taxes are being harmonized with European Union directives, which means higher value added tax rates on unprocessed foodstuffs, municipal services, and construction material, and higher excise rates on tobacco and alcohol. The reform of personal income tax law has been delayed, because of concern about the fairness of a rate reduction for higher-income taxpayers and hesitation about the government's proposal to remove or scale down existing tax expenditure programs. Poland's personal income tax expenditure programs, introduced in 1992, have received growing attention as the cost of the programs has increased. Originally they were intended to compensate lower-income taxpayers for the withdrawal of price subsidies. But most of them are extremely regressive, benefiting higher-income taxpayers. Tax expenditures are reductions in tax liabilities that result from preferential provisions, such as deductions, exemptions, credits, deferrals, preferential tax rates, and exclusions from taxation. They are effective government spending channeled through the tax system, usually as substitutes for direct government spending to achieve fiscal and political objectives. The authors contend that strengthening the administration of Poland's tax expenditure programs is the first step toward making them effective and equitable, limiting their costs, and preventing the tax base from shrinking. They discuss options for increasing the scrutiny of the tax expenditure programs, defining their opportunity costs and effect on the tax system. Currently these programs enjoy a funding advantage over direct spending programs because they are not subject to systematic review. To limit the expansion of these programs and reduce their less desirable effects on the system, the authors suggest defining a benchmark tax structure, establishing sunset dates for the programs, forecasting their costs, and reviewing their economic effectiveness, efficiency, and equity by comparing them with direct expenditures and subsidies.Tax Policy and Administration,Public Sector Economics&Finance,Taxation&Subsidies,Environmental Economics&Policies,Strategic Debt Management
Hash-Based Hierarchical Caching and Layered Filtering for Interactive Previews in Global Illumination Rendering
No full textModern Monte-Carlo-based rendering systems still suffer from the computational complexity involved in the generation of noise-free images, making it challenging to synthesize interactive previews. We present a framework suited for rendering such previews of static scenes using a caching technique that builds upon a linkless octree. Our approach allows for memory-efficient storage and constant-time lookup to cache diffuse illumination at multiple hitpoints along the traced paths. Non-diffuse surfaces are dealt with in a hybrid way in order to reconstruct view-dependent illumination while maintaining interactive frame rates. By evaluating the visual fidelity against ground truth sequences and by benchmarking, we show that our approach compares well to low-noise path traced results, but with a greatly reduced computational complexity allowing for interactive frame rates. This way, our caching technique provides a useful tool for global illumination previews and multi-view rendering
