Structural design of advanced cathodes is a promising strategy to suppress the shuttle effect for lithium‐sulfur batteries (LSBs). In this work, the carbon cloth covered with CoS2 nanoparticles (CC‐CoS2) is prepared to function as both three‐dimensional (3D) current collector and physicochemical barrier to retard migration of soluble lithium polysulfides. On the one hand, the CC‐CoS2 film works as a robust 3D current collector and host with high conductivity, high sulfur loading, and high capability of capturing polysulfides. On the other hand, the 3D porous CC‐CoS2 film serves as a multifunctional interlayer that exhibits efficient physical blocking, strong chemisorption, and fast catalytic redox reaction kinetics toward soluble polysulfides. Consequently, the Al@S/AB@CC‐CoS2 cell with a sulfur loading of 1.2 mg cm−2 exhibits a high rate capability (≈823 mAh g−1 at 4 C) and delivers excellent capacity retention (a decay of ≈0.021% per cycle for 1000 cycles at 4 C). Moreover, the sandwiched cathode of CC‐CoS2@S/AB@CC‐CoS2 is designed for high sulfur loading LSBs. The CC‐CoS2@S/AB@CC‐CoS2 cells with sulfur loadings of 4.2 and 6.1 mg cm−2 deliver high reversible capacities of 1106 and 885 mAh g−1, respectively, after 100 cycles at 0.2 C. The outstanding electrochemical performance is attributed to the sandwiched structure with active catalytic component. Sandwiched cathodes constructed from CoS2‐modified carbon clothes (CC‐CoS2) are designed for high sulfur loading lithium‐sulfur batteries. The sandwiched cathode not only offers three‐dimensional (3D) current collector and host with enough voids for volume expansion to maintain the structural stability, but also promotes the physical encapsulation, chemical entrapment and catalytic conversion of polysulfides species to suppress the shuttle effect.

Carbendazim (CBD) is widely used as a fungicide that acts as a pesticide in farming to prevent crop diseases. However, CBD can remain on crops for a long time. When consumed by humans and animals, it produces a range of toxic symptoms and poses a serious threat to their health. Therefore, the detection of CBD is necessary. Traditional assay strategies for CBD detection, although sensitive and practical, can hardly achieve fast, robust monitoring during food processing and daily life. Here, we designed a novel electrochemical sensor for CBD detection. In this method, iron oxyhydroxide nanomaterial (β-FeOOH) was first prepared by hydrothermal method. Then, a molecularly imprinted polymer (MIP) layer was electropolymerized on the surface using CBD as the template and resorcinol (RC) as the functional monomer. The synergistic interaction between β-FeOOH and MIP endows the MIP/β-FeOOH/CC-based electrochemical sensor with high specificity and sensitivity. Under optimal conditions, the MIP/β-FeOOH/CC-based sensor showed a wide linear range of 39 pM–80 nM for CBD and a detection limit as low as 25 pM. Therefore, the as-prepared sensor can be a practical and effective tool for pesticide residue detection. Graphical abstract

Zusammenfassung Komplexe Wunden beeinträchtigen den Patienten nicht nur hinsichtlich der Lebensqualität und des Sterblichkeitsrisikos, sondern verursachen auch zusätzliche Kosten für verlängerte, stationäre Krankenhausaufenthalte und für eine möglicherweise prolongierte, poststationäre Behandlung. Ein innovatives Behandlungsverfahren, bestehend aus kaltem atmosphärischem Plasma, der Verwendung einer Kombination aus Kohlefaser als direkte Wundauflage und Unterdrucktherapie sowie Spüllösungen mit Freisetzung von Singulett-Sauerstoff, ermöglicht es, infizierte Implantate zu reinigen. Das zunächst für infizierte Kunstherzsysteme entwickelte Verfahren empfiehlt sich aufgrund seiner nachgewiesenen Wirksamkeit und der außerordentlich guten Verträglichkeit ebenfalls für andere komplexe Wunden in der Herzchirurgie, wie die Sternuminfektion. Mit diesem Verfahren kann das initial erforderliche Débridement begrenzt werden. Es ermöglicht einen gewebeschonenden Therapieansatz. Ferner verkürzt die intensivierte Wundbehandlung die Therapiezeiten und spart somit Kosten ein.

The textile industry is a large source of pollution due to the production of raw materials (natural and synthetic fibers), preparation and finishing processes, as well as due to textile waste, especially the post-consumer waste. This paper is an attempt to change the perception concerning such waste. In the context of circular economy, textile waste has to be conceived as a source for carbon and energy. A new attitude is compulsory due to the increase of post-consumer waste quantity since the volume of textile consumption has lately increased. Fast fashion cycle and cheaper textile products having a shorter lifetime led to an increase of the quantity of post-consumer textile waste. Demands for pollution reduction generated the concern to upcycle the textile waste in order to recover, at least partially, the materials as well as the energy consumed for their manufacture, reducing accordingly the carbon and water footprints of these products,. The scarcity of raw materials and of fossil fuels, the high environmental impact of the simple disposal of waste, imposed a new policy regarding the transformation of the linear economy which characterizes today’s textile industry into a circular one, leading to a lower environmental impact. This involves the valorization of post-consumer waste by recycling or at least by a partial recovery of the materials and energy spent for the manufacture of these products. A good management of post-consumer textile waste is mandatory for attaining a zero waste target. Some good practices in the field are presented by this paper.

Se determinan las entalpías de inmersión de cinco telas de carbón activado en CCl4, H2O, y soluciones de NaOH y HCl 0,1 M. Los valores de área superficial de las telas se encuentran entre 243 y 848 m2g-1, y presentan una relación lineal con las entalpías de inmersión en CCl4. Las entalpías de inmersión de las telas de carbón están entre 5,49 y 42,3 Jg-1 para el CCl4 y entre 3,83 y 7,54 Jg-1 para el H2O. Las entalpías de inmersión en las soluciones se relacionan con los contenidos de grupos ácidos y básicos, y se encuentra que para el primer caso, al aumentar la entalpía de inmersión en NaOH, aumenta la acidez total. Se calcula el factor hidrofóbico a partir de las entalpías de inmersión en CCl4 y H2O, que indica la interacción del sólido con compuestos polares y apolares, y a la vez se relaciona con el pHPZC de cada muestra.

The surface electromyography (SEMG) is one of the most popular bio-signals that can be applied in health monitoring systems, fitness training, and rehabilitation devices. Commercial clothing embedded with textile electrodes has already been released onto the market, but there is insufficient information on the performance of textile SEMG electrodes because the required configuration may differ according to the electrode material. The current study analyzed the influence of electrode size and pattern reduction rate (PRR), and hence the clothing pressure (Pc) based on in vivo SEMG signal acquisition. Bipolar SEMG electrodes were made in different electrode diameters Ø 5–30 mm, and the clothing pressure ranged from 6.1 to 12.6 mmHg. The results supported the larger electrodes, and Pc showed better SEMG signal quality by showing lower baseline noise and a gradual increase in the signal to noise ratio (SNR). In particular, electrodes, Ø ≥ 20 mm, and Pc ≥ 10 mmHg showed comparable performance to Ag-Ag/Cl electrodes in current textile-based electrodes. The current study emphasizes and discusses design factors that are particularly required in the designing and manufacturing process of smart clothing with SEMG electrodes, especially as an aspect of clothing design.

Waterless dyeing of polyamide 6.6 using scCO2 (supercritical carbon dioxide) was investigated. PA (polyamide) fibers can be dyed with various dyes, including disperse dyes. The conventional aqueous dyeing process uses large amounts of water and produces polluted water. Considering these environmental issues, waterless dyeing of fibers is a forefront issue, and utilization of supercritical carbon dioxide (scCO2) is a commercially viable technology for waterless dyeing. This study tested PA6.6 (polyamide 6.6) dyeing in scCO2 at 100 °C 220 bar pressure for 45 min. Color measurements and color fastness tests were performed, as well as tensile strength, scanning electron microscope (SEM) analysis, and Fourier transform infrared spectroscopy (FTIR) analysis. PA6.6 fabrics yielded higher K/S (color strength, the Kubelka–Munk equation) values with larger molecular weight dye and almost the same color strength with medium and small-sized dyes, demonstrating the ability of dyeing in a supercritical environment without water as a more environmentally friendly dyeing option compared to conventional dyeing.

Sportswear is an essential auxiliary wear for physical education activities in colleges and universities. Unfortunately, most sports equipment is made of heavyweight, expensive, and easily rusted metals. Herein, we report the recent progress in carbon-based nanocomposites for sportswear and sensors. To extend the service life of sportswear, advanced lightweight materials for sports goods are briefly discussed. Carbon materials such as 0D fullerenes, 1D carbon nanotubes, 2D graphene, and 3D graphite and their nanocomposites are more and more widely used in various industries in the world, and sportswear has no exceptions. Their superior performance and huge potential have a certain impact on improving sports performance. Firstly, we overviewed the advantages and multifunctional carbon nanocomposites in sportswear, and wearable sports applications at the present stage are explored. While simultaneously monitoring health or energy storage applications also explored, indeed the integration of all desirable functions into lightweight wearable sports goods emerged as a significant breakthrough for effective sports activities. More importantly, some sportswear prototypes equipped with unprecedented characteristics have also been overviewed in this review. Despite the recent developments, many barriers and difficulties still remain. New prospects are also suggested. This article seeks to inspire sports research communities to drive onward real-time advancement in the sports industry.

This study aimed to identify the benefits and challenges of clothing reuse, both in terms of fashion companies collecting unwanted clothing and consumer attitudes, focusing on Japanese fashion companies and consumers To achieve the goal, this study conducts a survey to gain an overview on the supply chain of fashion brands carrying out a take-back program in Japan. This study also conducted a questionnaire survey to gage consumers’ awareness and purchasing decisions regarding second-hand clothes and to clarify the annual CO2 emissions generated by different clothing maintenance habits among second-hand clothes consumers. Business review results revealed that large companies only take back their products for reuse or recycling to control product quality. The questionnaire survey results revealed the primary motivations for purchasing second-hand clothes were financial advantages and the desire for fashionable styles. The environmental impact assessment results indicated that purchasing a second-hand shirt in the context of a circular economy produces 6.71 kg-CO2 less than buying a newly produced shirt within a linear economy (9.23 kg-CO2). Additionally, based on the questionnaire results, this study unveiled how laundry habits affect CO2 emissions during the garment use phase.

Global warming represents a major subject on all society levels including governments, economic actors and citizens. The textile industry is often considered a polluting activity. In this project, French textile manufacturers sought to quantify the carbon footprint (CF) of sold clothes and household linen using Life Cycle Assessment in France for the purpose of reducing it to meet the constraints of Paris Agreement by 2050. First, manufacturers calculated the carbon footprint of 17 clothes and household linen products and established alternative scenarios for four production routes. Secondly, they modeled the supply of the upstream sector through different countries. Based on imports of textile products, their calculated CF for one French person reaches 442 kg of CO2eq/year. Means of action to reduce this carbon footprint by a factor of 6 (74 kg of CO2eq/person/year for textiles) are calculated and are the following: installing the most energy-intensive production processes in a country with a low carbon electricity mix, avoiding unsold goods, implementing eco-design approaches and enhancing the value of end-of-life products with reuse or recycling. Therefore, CF for textiles per capita is reduced to 43 kg CO2eq/year which goes beyond the objectives of Paris Agreement and facilitates carbon neutrality in the textile sector. The first priority for reducing the French carbon footprint of clothes and household linen would be to locate textile production in countries with (i) low carbon electricity, (ii) to reduce unsold items, and (iii) to elaborate ecodesign of product including circular economy.
