Liquid-Metal Molecular Scissors.

Molecules are the smallest units of matter that can exist independently, relatively stable, maintaining their physical and chemical activities. The key factors that dominate the structures and properties of molecules include atomic species, alignment commands, and chemical bonds. Herein, we reported a generalized effect in which liquid metals can directly cut off oxygen-containing groups in molecular matter at room temperature, allowing the remaining groups to recombine to form functional materials. Thus, we propose basic liquid-metal scissors for molecular directional clipping and functional transformations. As a proof of concept, we demonstrate the capabilities of liquid-metal scissors and reveal that the gallium on the surface of liquid metals directly extracts oxygen atoms from H2O or CH3OH molecules to form oxides. After clipping, the remaining hydrogen atoms from the H2O molecules recombine to form H2, while the remaining fragments of CH3OH produce H2, carbon materials, and carboxylates. This finding refreshes our basic understanding of chemistry and should lead to the development of straightforward molecular weaving techniques, which can help to overcome the limitations of molecular substances with single purposes. It also opens a universal route for realizing future innovations in molecular chemical engineering, life sciences, energy and environment research, and biomedicine.

Rational Design of a Hydrophilic Core-Hydrophobic Shell Yarn-Based Solar Evaporator with an Underwater Aerophilic Surface for Self-Floating and High-Performance Dynamic Water Purification.

Interfacial solar vapor generation holds great promise for alleviating the global freshwater crisis, but its real-world application is limited by the efficiently choppy water evaporation and industrial production capability. Herein, a self-floating solar evaporator with an underwater aerophilic surface is innovatively fabricated by weaving core-shell yarns via mature weaving techniques. The core-shell yarns possess capillary water channels in the hydrophilic cotton core and can trap air in the hydrophobic electrospinning nanofiber shell when submerged underwater, simultaneously realizing controllable water supplies, stable self-flotation, and great thermal insulation. Consequently, the self-floating solar evaporator achieves an evaporation rate of 2.26 kg m-2 h-1 under 1 sun irradiation, with a reduced heat conduction of 70.18 W m-2. Additionally, for the first time, a solar evaporator can operate continuously in water with varying waveforms and intensities over 24 h, exhibiting an outdoor cumulative evaporation rate of 14.17 kg m-2 day-1.

Multicultural Elements of the Mongol-Yuan Silk Textile

Textiles have played a significant role in understanding the life and thinking of its users. Yuan silk textile greatly merges the weaving styles from the land that the Mongol-Yuan conquered. This paper offers an explanation on a specific Yuan silk textile by analyzing its motifs, colors, techniques, and the users attitudes toward them. This textile would require an overall look with Han and Islamic pattern structure, with a Taoism symbol, Buddhist lotus, and Mongolian nomadic totems. These features can be discussed with a comparison of the works of previous dynasties and evinced by historical records. This paper proposes that the previous dichotomy or setting of the Yuans preference for some cultures is misleading. Instead, it should be realized that the motifs and techniques imply the Mongol Yuans admiration of Buddhism, Han culture, and Islamic weaving techniques. In this admiration, the Yuans ban on the application of some motifs conveys their narrow cultural controls and causes the misunderstanding that denies their contribution to cultural communication. A motif cannot be clearly defined as a representation of one single culture. In other words, the Yuan court followed the confluence of diverse cultures with the development of commercial and travel.

Understanding Gold Textiles: Case Studies of Gold Threads from the Bronze Age and Antiquity in Europe

The production of textiles, in terms of weaving techniques, has a long history in Europe, and dates back to the Stone Age, the time during which the first farming communities arrived in the Mediterranean and Central Europe, in the 7th/6th millennium BC. The first evidence of textile tools, like spindle whorls and loom weights, demonstrate that people made an important step forward in mechanizing this craft, not only twisting fibers and interlacing strands purely by hand, but also inventing tools to increase efficiency. Through the development of textile techniques, we see the unleashing of enormous creative power that stimulated even more advanced techniques to create specific structures and patterns — these still form an important part of our European cultural heritage, which was also studied with the COST Action Euro Web. As an example, the art of blue dyeing has been listed by UNESCO as an example of Intangible Heritage in Austria, Slovenia, Czech Republic, and Slovakia since 2018;1 all over the world, different techniques have been awarded Textile Intangible Cultural Heritage status.2 To preserve craft knowledge for the future, it is important to understand details on ancient weaving techniques. This knowledge might not only be used for research and science communication, but also could potentially be integrated into the daily lives of modern people. The case studies presented here will centre on the incorporation of gold threads into textiles, a method of decoration which has been found across different time periods and areas in Europe and the Mediterranean.3 In this contribution, we focus on Late Bronze Age contexts, like Ebreichsdorf and Vösendorf in Austria and Óbuda in Hungary, as well as others from the Roman Period, such as Pompeii, Herculaneum, and Oplantis in Italy. Reconstructing textiles from European archaeological contexts that are thousands of years old is a demanding task. Contrary to other parts of the world, the environmental conditions in most areas of Europe are not conducive to the preservation of organic remains in general, and textile materials in particular.4 In fact, and while exceptions do exist (see below), direct evidence for the textile component of the material worlds of prehistoric and ancient Europe is, for the most part, fragmentary and incomplete. This being said, there are several different strands of evidence that can be used to achieve empirically grounded scientific reconstructions of the types of textiles used during this period across Europe. The main sources for such reconstructions can be divided into several categories: Archaeological sources (textiles and their scientific analysis, tools); iconographic sources; written sources; ethnographic/folkloristic evidence; and experimental archaeology.

Composite metamaterial antenna with super mechanical and electromagnetic performances integrated by three-dimensional weaving technique

The integration of structure and function was crucial for the application of microstrip antennas. Layered microstrip antennas were prone to delamination, which severely limits their performance stability. The textile conformal microstrip antenna with integrated structure design prevented the layered failure and greatly improved the damage resistance of the antenna. However, textiles had an inherent deficiency in suppressing surface waves due to their discontinuous mesh structure, critically deteriorating the radiation performance of microstrip antennas. Electromagnetic metamaterial with a specific pattern resonated in the excitation of electromagnetic waves to form a forbidden bandgap, which was expected to suppress surface wave radiation of microstrip antennas. In this study, a textile-based microstrip antenna integrated with electromagnetic metamaterials (MA-EBG) was proposed by embedding conductive copper wires in three-dimensional (3D) spacer fabric to form an integrated structure. Due to the function of the forbidden bandgap in metamaterial structure, the surface wave radiation was suppressed and the gain of antenna was increased from 5.1 dB to 9.6 dB. Owing to the tight physical binding, MA-EBG retained its structural integrity with proper electromagnetic performance under the impact of 24 J. The application of electromagnetic metamaterials elevated the gain of textile-based microstrip antennas, which provided a new method for the design of high-gain textile-based microstrip antennas with excellent mechanical properties.

INTEGRATING UPCYCLING APPROACH USING AN INDIGENOUS TEXTILE WEAVING CRAFT

This research study examines how upcycling is applied and the techniques for creating clothing in mass production, and it shows how upcycling may be a successful strategy for cutting down on textile waste. Businesses may lessen their impact on the environment and boost their bottom lines by recycling leftovers and decreasing waste in addition to minimizing their environmental impact. The study demonstrates that the quantity of trash produced varies depending on the size of the facility and the residual material kinds, and that some leftover material types can be recycled up to 80% of the time. The report also underscores the significance of transparency in comprehending and managing textile waste, and it draws attention to the fact that upcycling design is distinct from traditional design in that it depends on the properties of the waste materials. The project is situated in the Indian region of Jaipur and aims to improve weaving techniques. This paper outlines a strategy for incorporating upcycling into a traditional textile weaving technique. The study focuses on combining conventional weaving methods with cutting-edge design components to produce distinctive and sustainable items from waste materials. The process involves gathering and choosing waste materials, creating new things from scratch, and prototyping them, and assessing their commercial feasibility and cultural relevance. The findings of this study show that upcycling can be incorporated into indigenous textile weaving skills to preserve cultural heritage and encourage ecological practices. The findings emphasize the significance of considering both economic viability and cultural significance when developing upcycling projects, as well as the possibility for such initiatives to help preserve and revive conventional weaving techniques.

Experimental study on mechanical, damping and corrosion properties of Inconel 718 hard-faced stainless steel 304 using cold metal transfer

Cold Metal Transfer process is used to hard-face the Inconel 718 alloy onto the Stainless Steel 304 material. The optimized parameters from the Bead on Plate trials were determined as a wire feed rate of 7 m/min, deposition speed of 15 cm/min, welding current, and voltage of 175 A and 14.9 V, respectively. Hard-facing is carried out with the sinewave weaving technique along 30 % of overlapping beads. The analysis is focused on revealing the hard-faced specimens' microstructural, mechanical, and electrochemical corrosion properties. The hard-face layer exhibits grains of mixed modes, including columnar, cellular, and fine equiaxed grains. The increased heat transfer disintegrates grain formation and reduces secondary arm spacing development. SEM-Elemental mapping shows the reduction of Niobium (3.61 %) segregation and laves formation. The overlay layer has a maximum hardness of 343.1 HV0.5 over the base substrate with 204 HV0.5. The impact test reveals the hard-faced layer absorbs more energy (26.3 %) than the substrate. Dynamic Mechanical Analysis results indicate overlay layer enhancing damping properties. The electrochemical corrosion test findings suggest that the hard-faced layer's high corrosion potential (Ecorr = 8.533 mV) corresponds to a high corrosion resistance. Phase and intermetallic formations, distribution of elements, fractured and corrosive surface morphologies are analyzed using SEM, EDX, and elemental mapping results.

A Systematic Integration Study of Traditional Hand-Weaving Techniques in Lingnan Region in the Context of Deep Learning

Abstract In this paper, firstly, on the basis of the traditional hand weaving technique in Lingnan area, modern digital technology is used to integrate it systematically, so as to construct the three-dimensional weaving technique. Secondly, the structural properties of the three-dimensional woven fabrics are investigated through the two-step and four-step weaving methods in terms of the movement trajectories of the three-dimensional woven fabrics within the cross-section. Finally, the basic properties of bamboo weaving materials were analyzed in order to facilitate the force simulation analysis of the obtained morphological model samples of parametric Lingnan region bamboo weaving craft products using the structural simulation analysis software SIM-SOLID. The results show that in the structural force study of bamboo weaving craft products, the equivalent viscous damping coefficient is calculated by taking the first hysteresis loop of each stage of the loading cycle, and its maximum deformation is 0.428 mm, which is 0.003 mm smaller than that of the model with unfixed joints, which indicates that the performance of the Lingnan region weaving technique is optimized obviously by adopting the three-dimensional weaving technique. This paper provides theoretical references for the digital integration of traditional hand-woven techniques and the enhancement of structural properties of woven materials in the Lingnan region.

Weave Technique for Reconstruction of Medial Collateral Ligament and Posterior Oblique Ligament: A Functional Percutaneous Approach Using Gracilis Tendon

Background: Injury to the medial collateral ligament (MCL) is common. MCL injuries, with impairment of its superficial portion, associated with the deep portion, lead to valgus instability and extrusion of the medial meniscus, resulting in instability and increased pressure in the medial compartment, with consequent damage to the cartilage. We can synthesize this set of structures as the medial meniscocapsular complex. Treating medial, superficial, and deep capsular meniscal complex together aims to restore the normal anatomy, stability, and function of the medial meniscus. Indications: • Anterior cruciate ligament with MCL grade III or MCL grade II • MCL grade III or grade II with clinical instability Technique Description: An arthroscopic examination was performed to assess the “floating meniscus” sign and to confirm a tear of the MCL. The gracilis tendon is harvested in a usual fashion, leaving its distal insertion pedicle fixed to the tibial bone. An incision over the medial epicondyle is made, and a 6-mm drill is used to create a 2.5-cm bone tunnel. The passage of the medial subfascial graft is made toward the medial epicondyle. At this point, its fixation is performed with an interference screw. After fixing the anterior arm, we will return with the free portion of the graft in the most posterior portion and also percutaneously. This posterior arm is biologically fixed, closing the sartorius fascia over the 2 arms of the reconstruction with periosteal stitches. Results: Reconstruction tests were performed on cadaver models, obtaining a graft tension without compromising the range of motion (ROM) and a good result in their final analysis. We ended up publishing our results in a clinical study, with good functional results in both the Lysholm and Tegner scores, at a follow-up of 2 years. Discussion/Conclusion: We present an arthroscopic-assisted technique for a medial, percutaneous, aesthetic, and extremely functional approach. A technical limitation of our procedure is the absence of a biomechanical test for the gracilis double reconstruction: a strong point is that we performed some reconstruction tests on cadaver models, obtained good visual results and graft tension without compromising the ROM, and performed a positive clinical study with a minimum follow-up of 2 years. In conclusion, a simple and inexpensive technique that uses known anatomic principles of graft placement, without compromising ROM was performed.

Construction and application of a knowledge graph-based question answering system for Nanjing Yunjin digital resources

Nanjing Yunjin, one of China's traditional silk weaving techniques, is renowned for its unique local characteristics and exquisite craftsmanship, and was included in the Representative List of the Intangible Cultural Heritage of Humanity by UNESCO in 2009. However, with rapid development in weaving technology, ever-changing market demands, and shifting public aesthetics, Nanjing Yunjin, as an intangible cultural heritage, faces the challenge of survival and inheritance. Addressing this issue requires efficient storage, management, and utilization of Yunjin knowledge to enhance public understanding and recognition of Yunjin culture. In this study, we have constructed an intelligent question-answering system for Nanjing Yunjin digital resources based on knowledge graph, utilizing the Neo4j graph database for efficient organization, storage, and protection of Nanjing Yunjin knowledge, thereby revealing its profound cultural connotations. Furthermore, we adopted deep learning algorithms for natural language parsing. Specifically, we adopted BERT-based intent recognition technology to categorize user queries by intent, and we employed the BERT + BiGRU + CRF model for entity recognition. By comparing with BERT + BILSTM + CRF, BERT + CRF and BILSTM + CRF models, our model demonstrated superior performance in terms of precision, recall, and F1 score, substantiating the superiority and effectiveness of this model. Finally, based on the parsed results of the question, we constructed knowledge graph query statements, executed by the Cypher language, and the processed query results were fed back to the users in natural language. Through system implementation and testing, multiple indices including system response time, stability, load condition, accuracy, and scalability were evaluated. The experimental results indicated that the Nanjing Yunjin intelligent question-answering system, built on the knowledge graph, is able to efficiently and accurately generate answers to user’s natural language queries, greatly facilitating the retrieval and utilization of Yunjin knowledge. This not only reinforces the transmission, promotion, and application of Yunjin culture but also provides a paradigm for constructing other intangible cultural heritage question-answering systems based on knowledge graphs. This has substantial theoretical and practical significance for deeply exploring and uncovering the knowledge structure of human intangible heritage, promoting cultural inheritance and protection.

Role of Traditional Weavers in Socio – Economic Development

Objective: This study analyses the role of traditional weavers towards socio – economic development by examining the market competition between traditional woven clothes and clothes produced from power loom. This paper also discusses the relationship between traditional cultural expressions with moral rights of Copyright Law. Methods: This study is based on the literature collected from secondary sources. It relies on Constitution of India, published research articles, text books, reports on international conventions, etc. The literature is analyzed by using descriptive – analytical method. Results: Intellectual Property Law is very narrow to protect traditional knowledge (TK) and traditional cultural expressions (TCE). IPR laws require the work of the people to be original and novel. Traditional weavers do not fulfill the requirement of originality and novelty because the products are result of TK and TCE passed down from many generations. A sui – generis law is felt necessary to protect the hand woven dresses made by the traditional weavers. Such sui – generis law may include positive protection and defensive protection as provided under World Intellectual Property Organization (WIPO) to help traditional weavers access share of equal benefit and restrict the third parties from obtaining rights over the products derived from TK and TCE. Customary law is also one of the potential approaches to holistically recognize the rights of traditional weavers. Suggestions: It is recommended to encourage traditional weaving for the sustainability of weaving culture. However the present generation can enhance the weaving techniques by blending it with new technologies. The marketing strategy should be learnt by traditional weavers to meet the expectation of globalised market. There should be direct communication between customers and weavers to understand the expectation of customers. This will open path to traditional weavers to develop their skills, designs, and promote their products directly in the market. To raise awareness among consumers, the hand-woven goods should be promoted. The Handloom Act of 1985 should be implemented. The state's department of handloom should frequently inform weavers about the reserved commodities. Power loom facilities should be legally registered with a statement that none of the restricted items listed under Handloom Act, 1985 will be produced. The power loom weavers should be held legally responsible if it is discovered that they are making reserved items. Copyright Law should include weaving as TCE and grant protection under moral rights.

Tradition of Beaded Decoration in the Ukrainian Folk Costume: Reconstruction of the Second Stage (Based on the Materials of Western Regions of Ukraine)

The article continues the previously started reconstruction of ethnic artistic tradition of beaded decoration in the Ukrainian folk costume. The authors’ vision of the second stage of development of this tradition (the end of the 19th– the middle of the 20th centuries) is presented. It was found that at the second stage of its development, the tradition of beaded decoration in the Ukrainian folk costume went through the phase of creative uplift. Ukrainian folk craftsmen considerably expanded the arsenal of technical as well as artistic and stylistic means of their creative works. The following techniques were used: typesetting, sewing “v prykrip“, stringing, weaving, embroidery, etc. The typology of beaded components of the folk costume expanded significantly. Alongside with overhead jewelry and headdresses, the beaded decoration emerged in the structure of several old and new components of clothes and accessories. By virtue of the implementation of the techniques of weaving and embroidery, artistic stylistics developed further. In the compositions of beaded components of the costume, apart from the motifs of geometric shapes, the motifs of geometrised shapes appeared, as well as the national symbols. The colouring of beaded artworks was significantly enriched. Successful development of all-Ukrainian and local features of folk art continued. The knowledge, accumulated by the authors, will be of a great interest to ethnologists, art historians as well as modern folk craftsmen of beaded artworks.

Mambaleh Nan Talipek Terinspirasi Dari Kegiatan Manganyam Kampia Di Matua Kabupaten Agam

The Mambaleh Nan Talipek dance work departs from manganyam kampia activities in Matur, Agam Regency. The creators chose to transform the woven techniques such as the lipek technique and the twisting technique onto the dancer's body, so that in making the work they are more focused on developing the woven technique into the structure of the dance work by Mambaleh Nan Talipek which is divided into three parts. In the first part, the artist transforms the lipek technique using his hands, feet and body. The second part transforms the weaving technique by using the properties of the cloth and in this part the dancers perform complementary movements. In the third part, the artist shows the woven Kampia into dance. In this section, Kampia is used to show how the results of the two techniques are formed. This work is strengthened by live music and other compositional elements, the methods used in composing this work are methods of exploration, improvisation, observation, and formation. This work is supported by seven female dancers, with cultural themes and non-dramatic types.
