This study analyzed the presence and effect of sexual appeal of plus-size models using Victoria's Secret's Instagram content. A content analysis using roBERTa deep-learning model found that, plus-size models’ sexual appeals increased number of likes and comments, but explicit sexual appeals resulted in less positive sentiments than thin models’.

A thermally conductive film can be used to laterally conduct heat along the surface of glass windows, toward its edges where a heat sink could be located, thereby reducing temperature differential between the inside and outside surfaces of the window and thus lowering cross-sectional conductive heat transfer. This technique can offer optimized thermal energy management to modern buildings without the weight and cost of double- or triple-glazed window panels. In this work, a thermally conductive film was developed using carbon dots with inherently high thermal conductivity. Nitrogen atoms were then added to the carbon dots structure to intensify high-frequency phonon that would result in higher lateral thermal conductivity. The nitrogen-decorated carbon dots (NCDs) were prepared by a simple hydrothermal synthesis of citric acid with the addition of ethylenediamine as the N source. The NCDs were added to a cellulose-based solution and drop-casted onto FTO glass resulting in a transparent, laterally thermally conductive film, that also blocks ultraviolet (UV) and high-intensity blue light radiation. The visible-light transmission of the NCDs’ film was found to be up to 65%, comparable to the commercial solar films. The lateral thermal conductivity of the NCDs’ film increases with increasing N content up to an optimum level, suggesting the role of N to “concentrate’ the high-frequency phonons responsible for effective lateral thermal conductivity of the films.

Carbon quantum dots (CQDs) as a rising class of carbon family have gained widespread attention in view of their multiple properties such as great photoluminescence (PL) properties, facile synthesis route, needing economical and cheap raw material, high physiochemical stability, and simple functionalization. This makes CQDs highly versatile and with potential for different applications. To date, CQDs-enabled photocatalysts are regarded as one of the most efficient technologies to degrade pollutants in water; however, poor activity under visible light and the recombination of photogenerated electron and hole pairs hinder getting an ideal performance that may be applied on a large scale. Conventional techniques have been modified via a new advanced method. In this review, we highlighted the strategies to improve the activity of conventional semiconductor photocatalysis via coupling with CQDs, and strategies to improve the photocatalytic activity such as functionalization, doping, and Z-scheme heterojunctions were discussed in detail. This review also covered the CQDs heterojunction application in pollutant degradation and discussed several examples with high-performance photocatalytic activity.

High surface carbon aerogels with hierarchical and tunable pore structure were prepared using ionic liquid as carbon precursor via a simple salt templating method. The as-prepared carbon aerogels were characterized by nitrogen sorption measurement and scanning electron microscopy. Through instant visual observation experiments, it was found that salt eutectics not only serve as solvents, porogens, and templates, but also play an important role of foaming agents in the preparation of carbon aerogels. When the pyrolyzing temperature rises from 800 to 1000°C, the higher temperature deepens the carbonization reaction further to form a nanoporous interconnected fractal structure and increase the contribution of super-micropores and small mesopores and improve the specific surface area and pore volume, while having few effects on the macropores. As the mass ratio of ionic liquid to salt eutectics drops from 55% to 15%, that is, the content of salt eutectics increases, the salt eutectics gradually aggregate from ion pairs, to clusters with minimal free energy, and finally to a continuous salt phase, leading to the formation of micropores, uniform mesopores, and macropores, respectively; these processes cause BET specific surface area initially to increase but subsequently to decrease. With the mass ratio of ionic liquids to salts at 35% and carbonization temperature at 900°C, the specific surface area of the resultant carbon aerogels reached 2309 m2 g–1. By controlling the carbonization temperature and mass ratio of the raw materials, the hierarchically porous architecture of carbon aerogels can be tuned; this advantage will promote their use in the fields of electrodes and adsorption.

This paper introduces a nitrogen-doped ordered mesoporous carbon (NOMC) derived from glucosamine with hybrid capacitive behaviors, achieved by successfully combining electrical double-layer capacitance with pseudo-capacitance behaviors. The nitrogen doping content of the fabricated NOMC reached 7.4 at% while its specific surface area (SBET) and total pore volume reached 778 m2 g−1 and 1.17 cm3 g−1, respectively. A dual mesoporous structure with small mesopores centered at 3.6 nm and large mesopores centered at 9.9 nm was observed. The specific capacitance of the reported materials reached up to 328 F g−1, which was 2.1 times higher than that of pristine CMK-3. The capacitance retention rate was found to be higher than 87.9% after 1000 charge/discharge cycles. The supplementary pseudocapacitance as well as the enhanced wettability and conductivity due to the incorporation of nitrogen heteroatoms within the carbon matrixes were found to be responsible for the excellent capacitive performance of the reported NOMC materials.

Over its 20 years of practice, the Appellate Body gradually established a de facto stare decisis rule similar to that exists in common law system. Given the tight time constraint as provided in the DSU for an appeal process, the Appellate Body may face a situation where there is no sufficient time available for it to consider thoroughly all the elements for the interpretation of a provision, especially arguments or evidence of law that have not been raised even by the parties nor by the panel. If the issue whether Article XX of GATT 1994 can be invoked by China to justify a violation of paragraph 11.3 of its Accession Protocol had been decided in China-Raw Materials, can this issue be reopened and assessed again in China-Rare Earths? The author explored these two cases in light of the relevant WTO precedents as well as the common law thinking. This article concludes that it is both necessary and technically feasible to correct certain previous interpretation. Such a correction will contribute to further improvement in the clarification and interpretation of the covered agreements and accession protocols; hence give more confidence to Members that their rights and obligations under the treaty can be well preserved by a system with a built-in self-correction mechanism.

본 연구는 Poly(ether block amide) (PEBA)와 poly(dimethyl-siloxane) (PDMS)를 혼합한 블렌드막(PEBA: PDMS = 5 : 2,6 : 1 wt%)을 상전이법을 이용하여 제조하여, 이산화탄소의 분리능을 향상시키고자 하였다. PDMS와 PEBA (4033) 은 투과특성의 비교를 위해 각각 같은 방법의 단일막으로 제조되었고, 용매로는 n-butanol을 사용하였다. 제조된 막은 SEM 을 이용하여 morphology를 분석하였고, 압력에 따른 CO2와 N2의 투과도를 측정하였다. 실험결과, PEBA/PDMS 블렌드막은 3기압에서 단일 PDMS막에 비해 N2에 대한 CO2의 선택도가 4~5배 높은 것으로 나타났다.

The binder phase for TiC reinforced steel matrix composite was added in the form of elemental powders and master alloy powders. The microstructures, binder phase variation with TiC content and mechanical properties were evaluated. The addition of a type of binder phase largely effects the microstructure and mechanical properties. The binder phase variation from starting composition was observed with increase in wt% TiC content and this variation was higher when the master alloy powders were used as a binder. The response to heat treatment was decreased with an increase in TiC content due to the shift of binder phase from the starting composition.

The main object of this research was to examine the effect of sintering conditions on the microstructure of tungsten heavy alloys and how the resulting modification of the microstructure can be used to optimize their mechanical properties. Alloys composed of 88%, 93% and 95% wt. of tungsten and the balance is Ni: Fe in the ratio of 7:3 were sintered at different temperatures for different sintering holding times in hydrogen atmosphere. It was shown that the mechanical properties of the alloys, and especially their ductility, are harmed when tungsten grains are contiguous.

Since the reform and opening up, China has maintained rapid economic growth for nearly 40 years, and is the country with the fastest economic growth in the world. However, the rapid economic growth has also paid a huge social price, which is directly related to the unreasonable economic structure and extensive growth mode. Traditional engines of economic growth began to fade. This paper through the analysis to the theory of ancient and modern Chinese and foreign economists study on economic growth: economic growth is an extremely complex process, many factors influence the economic growth, correctly grasp the role of these factors in economic growth, to grasp the law of economic growth, the correct understanding of modern economic growth is very important. Sustained economic growth in China, on the basis of dynamic analysis, combined with the current economic situation at home and abroad, as you can see, in the high-speed economic growth since reform, various factors have been attenuation or mutation, the major developed countries and regions for the adjustment of the external imbalance in pressure, the depth of the global economic growth and recovery of the factors of uncertainty, It is difficult to maintain and improve the driving force and source of China’s economic growth in the future. The current industrialization process has reached a historical and international high level and is nearing the end. The growth rate of industrial investment will slow down significantly in the future. The demographic dividend is gradually depleting, and the savings rate will gradually decrease in the future. The era of rapid economic growth brought by demographic dividend and high savings rate in a long period of time will change. Therefore, based on the perspective of supply side demand and the development of new industries, the paper analyzes the driving force of traditional economic growth in China in the past, and holds that the driving force of consumption upgrading and digital economy are the important driving force of economic growth, and strives to improve the consumption structure of residents, increase the consumption rate and vigorously develop digital economy. Shifting China’s economic growth from relying on external demand to relying on domestic demand will provide strong support for high-quality development.
