Evolution and sustainability analysis of global tungsten trade pattern from the perspective of industry chain

Tungsten is an irreplaceable primary material and strategic resource for national economic development and modern national defense security. The endowment of tungsten ore resources in various countries is different; we should not only focus on the availability of tungsten ore itself but also the sustainability of its entire process from upstream supply to downstream industry demand. Analyzing the evolution of the supply and demand patterns of tungsten ore trade from the perspective of the industrial chain, identifying the key supply and demand subjects, and exploring the influencing factors of trade has become an important research topic. Therefore, we construct global tungsten trade networks based on the industrial chain, analyze its overall characteristics, explore critical trade supply and demand entities, and identify China’s trade position. We got some meaningful results: (1) The global tungsten trade networks have prominent power-law distribution characteristics. The trend of trade globalization is evident, but the dominance is still in the hands of a few developed countries or developing countries with developed manufacturing industries. (2) In different parts of the tungsten industry chain, the impact of resource endowment, industrial technology level, and geographical location on the country’s trade role is different. (3) China’s position in the global tungsten resource industry chain and value chain is constantly improving, but there is still a risk of high-end technology being “stuck.” This provides some suggestions for the systematic understanding of the evolution of the trade pattern of the tungsten industry chain and how countries occupy a dominant position in the game of tungsten resources.

Ligand-selective turn-off sensing, harvesting and post-adsorptive use of Dy(III) and Yb(III) by intrinsically fluorescent flower-shaped Gum Acacia-grafted hydrogels

Rare earth metals (REMs), such as Dysprosium (Dy) and Ytterbium (Yb), have experienced unprecedented demand in recent times due to their applications in high-end technologies. REMs are found only in select geographic locations placing tremendous economic constraints on their use. In this work, we have developed Gum Acacia-grafted hydrogels (GmAc-FluoroTerPs) that are capable of selective detection and capture of Dy and Yb. The intrinsically blue fluorescent polymer hydrogel GmAc-FluoroTerP has been optimized for Dy(III) and Yb(III) specific quenching, enabling limit of detection of the REMs at 0.13 nM and 60.8 pM, respectively. A comprehensive structural characterization of the fluorescent hydrogel has been performed via NMR, FTIR, XPS, EPR, TGA, XRD, TEM, SEM, EDX, TCSPC, and DLS. In addition to an in situ generated fluorophore, GmAc-FluoroTerP displays a distinctive aggregation induced emission enhancement in mixed solvents. The complexation of Dy(III)/Yb(III) with GmAc-FluoroTerP hydrogel has been characterized by XPS, TCSPC, and logic gate analyses, and the adsorptive capacity for Dy(III) and Yb(III) are found to be best reported till date as 125.57 mg g−1 and 102.27 mg g−1, respectively. Desorption at acidic pH allows recovery of the REMs. We also report semiconducting behaviour of the native fluorescent hydrogel, that is enhanced upon adsorptive capture of Dy(III) and Yb(III), with calculated band gaps at 1.37, 0.77, and 0.49 eV, respectively. The convergent sensing, capture, and reuse of Dy(III) and Yb(III) presented in this work promises a hitherto unreported template for application on other REMs.

Rare-earth praseodymium-substituted Bi5Ti3FeO15 exhibiting enhanced piezoelectric properties for high-temperature application

Owing to their exceptional piezoelectric effects, piezoelectric materials play a crucial role in high-end technologies and contribute significantly to the national economy. Bismuth layer-structured ferroelectrics (BLSFs) possess high Curie temperatures, making them a focal point of research in high-temperature piezoelectric sensor devices. However, their poor piezoelectric performance and low direct-current (DC) electrical resistivity hinder their effective deployment in high-temperature applications. To overcome these shortcomings, we employed composition optimization by partially substituting bismuth ions with rare-earth praseodymium ions. This approach enhances the piezoelectric performance and improves the DC electrical resistivity by preventing the loss of volatile bismuth ions and stabilizing the bismuth oxide layer (Bi2O2)2+, thereby reducing the concentration of oxygen vacancies. Consequently, we achieved a large piezoelectric constant d33 of 23.5 pC/N in praseodymium-substituted Bi5Ti3FeO15, which is three times higher than that of pure Bi5Ti3FeO15 (7.1 pC/N), along with a high Curie temperature TC of 778 °C. Additionally, the optimal composition of 4 mol% praseodymium-substituted Bi5Ti3FeO15 exhibits good thermal stability of electromechanical coupling characteristics up to 300 °C. This study holds promise for a wide array of high-temperature piezoelectric applications and has the potential to accelerate the development of high-temperature piezoelectric sensor technologies.

Modification of AgNP-Decorated PET: A Promising Strategy for Preparation of AgNP-Filled Nuclear Pores in Polymer Membranes.

Polymer-based membranes represent an irreplaceable group of materials that can be applied in a wide range of key industrial areas, from packaging to high-end technologies. Increased selectivity to transport properties or the possibility of controlling membrane permeability by external stimuli represents a key issue in current material research. In this work, we present an unconventional approach with the introduction of silver nanoparticles (AgNPs) into membrane pores, by immobilising them onto the surface of polyethyleneterephthalate (PET) foil with subsequent physical modification by means of laser and plasma radiation prior to membrane preparation. Our results showed that the surface characteristics of AgNP-decorated PET (surface morphology, AgNP content, and depth profile) affected the distribution and concentration of AgNPs in subsequent ion-track membranes. We believe that the presented approach affecting the redistribution of AgNPs in the polymer volume may open up new possibilities for the preparation of metal nanoparticle-filled polymeric membranes. The presence of AgNPs on the pore walls can facilitate the grafting of stimuli-responsive molecules onto these active sites and may contribute to the development of intelligent membranes with controllable transport properties.

A green extraction process for the selective recovery of Sc(iii) based on hydrophobic betaine derivative ionic liquids.

The efficient extraction recovery of scandium (Sc(iii)) is crucial for its application in high-end technology. Two novel hydrophobic carboxylic acid ionic liquids (ILs), namely, [lauryl betaine][bis(trifluoromethanesulphonyl)imide] ([Laur][Tf2N]) and [cocamidopropyl betaine][bis(trifluoromethanesulphonyl)imide] ([Coca][Tf2N]), were synthesized using two inexpensive amphoteric surfactants as cation sources. [Laur][Tf2N] (257 °C) and [Coca][Tf2N] (251 °C) exhibited good thermal stability and strong hydrophobicity. The viscosity of [Coca][Tf2N] (4.29 × 103 mP s) was higher than that of [Laur][Tf2N] (2.55 × 103 mPa s) at 25 °C. The optimal extraction conditions were an extraction equilibrium time of 40 min, an initial Sc(iii) concentration of 0.001 mol L-1, a sodium nitrate concentration of 0.5 mol L-1, and a pH of 3. The extraction efficiency of [Laur][Tf2N] and [Coca][Tf2N] could even exceed 98.7% and 96.0%, respectively. The cation exchange extraction mechanism was studied by slope analysis, IR spectroscopy and 13C NMR spectroscopy. Sc(iii) extracted using [Laur][Tf2N] and [Coca][Tf2N] could be completely stripped with 0.1 mol L-1 and 0.2 mol L-1 HNO3 once, respectively. The structure of the ILs was not broken after stripping, and the extraction efficiency of the ILs remained almost unchanged after five cycles. In addition, the extraction differences at different pH levels made it possible to separate Sc(iii) from other rare earths using ionic liquids [Laur][Tf2N] and [Coca][Tf2N].

The contribution of this paper focuses on exploring the factors that influence contemporary young peoples willingness to purchase the Apple Vision Pro and its similar high-end technology products.

Brazilian airway surgery survey indicates low overall numbers and need for improved teaching skills.

The Brazilian Society of Thoracic Surgeons (BSTS) conducted an on-line survey to determine the number of surgeons that perform adult and paediatric airway surgery, and to understand the practice patterns along the country. Active members were electronically invited to complete the questionnaire through the REDCapR platform. Invitations were sent from January to April 2020. The survey encompassed 40 questions that explored 4 different topics in the assessment of tracheal diseases: (1) Surgeon`s Demography; (2) Institutional profile, (3) Education and training in laryngo-tracheal surgery, (4) Preoperative and post operative evaluation. Eighty-nine % of the responders declared to perform tracheal surgery with a median of 5 tracheal resection procedures per year(IQR 3-12). Interaction with other specialties occurs in 37.3% of cases. Access to technology and devices is highly variable across the country. Resident training in airway surgery consists in traditional lectures in 97% of the cases. Training in animals(15.2%), cadavers(12.1%) and simulators(6.1%) are rare. Pre-operatory evaluation encompasses flexible bronchoscopy (97.8%) and/or CT scan of the airways (90.6%). Swallowing(20.1%) and voice(14.4%) disorders are rarely evaluated. Eighty nine % of the surgeons consider bronchoscopy to be the pre-operatory gold-standard exam, followed by CT scan (38.8%) and CT-3D reconstruction (37.4%). Brazilian surgeons refer that airway resection and reconstruction is part of their current practice, but the total number of procedures per surgeon per year is low. Access to high-end technology and equipment is heterogenous. Training offered to residents in most academic institutions relies on traditional lectures.

Engineering the Surface Chemistry of Graphite and Graphene by Covalently Anchored Triazole Derivative

Robust engineering the surface properties of layered materials is assigned as one of essential strategies for permanently improving their overall physicochemical behaviors towards high-end technology applications. In this regard, covalent functionalization of graphitic surfaces including graphene is performed upon electrografting of 4-(1H-1,2,4-triazol-1-ylmethyl) diazonium (4-TYD). The efficiency of this approach is determined by a state-of-the-art toolbox including cyclic voltammetry (CV), atomic force microscopy (AFM), scanning tunneling microscopy (STM), X-ray photoelectron spectroscopy (XPS), Kelvin probe force microscopy (KPFM) and Raman spectroscopy. The degree of the covalent functionalization is dependent on the molecular concentration of 4-TYD, in which the full monolayer is obtained upon electrografting with a 1 mM 4-TYD containing solution. The electrografted layer could be removed by thermal annealing leaving the pristine graphitic surfaces behind. This finding provides an efficient approach for robustly anchoring bioactive compounds onto graphene and other 2D materials in a controlled manner towards high-end technology applications.

Industrial Agglomeration and Corporate ESG Performance: Empirical Evidence from Manufacturing and Producer Services

Global climate change has emerged as a persistent global crisis. Under the dual pressures of industrial structure upgrading and ecological environment improvement, enhancing enterprise ESG (Environmental, Social, and Governance) performance can contribute to achieving sustainable development of the global economy. Selected a sample of 285 prefecture-level cities in China from 2005 to 2020 and panel data of listed companies to empirically examine the impact of industrial agglomeration on corporate ESG performance and its heterogeneity effects. We found that industrial agglomeration generally positively affects corporate ESG performance, with the significant promotion of ESG performance in manufacturing and a “U”-shaped relationship between producer services. Influence channel analysis found that industrial agglomeration acts on corporate ESG performance through the micro-transmission mechanisms of financing constraints, investment levels, market competitiveness, and internal control. Heterogeneity research found that the impact of manufacturing agglomeration on corporate ESG performance is more significant in capital-intensive and high-end technology industries, while producer service agglomeration has a more significant effect on ESG performance for knowledge-intensive industries. This study contributes to a better understanding of the microeconomic consequences of industrial agglomeration and expands the research perspective on the internal mechanisms and external incentives of corporate ESG performance. It provides a basis for local governments to analyze the different characteristics and microeconomic consequences of industrial agglomeration and provide empirical evidence for listed companies to adjust their ESG performance structure dynamically.

Industrial Agglomeration and Enterprise Innovation Sustainability: Empirical Evidence from the Chinese A-Share Market

The data from 285 prefecture-level cities in China are selected as research samples from 2005 to 2021, using the panel data of listed companies. The empirical study examines the impact of regional industrial agglomeration levels on enterprise innovation sustainability and its heterogeneity effects. The findings reveal that industrial agglomeration in the manufacturing sector significantly hampers enterprise innovation sustainability, while agglomeration in the producer services sector promotes it. Mechanism analysis demonstrates that industrial agglomeration affects enterprise innovation sustainability through the micro-conductive mechanism of financial constraints. Heterogeneity analysis shows that the impact of manufacturing agglomeration on enterprise innovation sustainability is more pronounced in technology-intensive and high-end technology industries, whereas the impact of producer services agglomeration varies significantly in knowledge-intensive and resource-intensive industries. Furthermore, heterogeneity analysis suggests that the influence of industrial agglomeration on enterprise innovation sustainability varies according to different firm characteristics. These research findings contribute to a deeper understanding of the microeconomic effects of industrial agglomeration and expand the research perspective on the internal mechanisms and external factors driving sustainable corporate innovation.

Impact of smart device use on objective and subjective health of older adults: findings from four provinces in China.

The digital divide has grown because of the deepening digitalization of the Chinese society and the intersection between high-end technology and the age structure. Older adults show an increasing level of weakness in digital life integration. What digital development can bring to older adults is a pressing concern. This study aims to investigate how smart device use affects older adults' health status and offers an empirical reference for improving their digital literacy and health. The data in this study were collected from an offline survey conducted from December 2021 to April 2022, which obtained 1110 valid samples of older adults This study used a multivariate ordered logit model, mediating effect model, and heterogeneity test to analyze the impact of smart device use on the health status of older adults. Smart device use has a significant positive effect on the self-rated, physical, and psychological health of older adults, and this positive effect is more pronounced among older adults living in urban areas or with a higher age. The average net effect of smart devices on each health status of older adults is 0.161 for self-rated health, 0.155 for physical health, and 0.071 for psychological health. In-depth research found that older adults' attitudes toward smart devices played a mediating role in the influence of smart device use on self-rated and psychological health respectively. The study found that smart device use had a positive effect on the health status of older adults and that the performance expectations and individualized needs of older adults exhibited an effective linkage between smart devices and health status. Smart device use could improve the overall health of older adults, especially the urban and low-age older adults. Promoting the understanding of the practicality of smart devices for older adults and the aging-oriented transformation of smart devices is an effective way to improve the health status of older adults. The findings provide theoretical support for the wide application of smart devices in older adults, and can effectively help eHealth practitioners implement accurate geriatric health support strategies.

Structure, Biology, and Applications of Filamentous Bacteriophages.

The closely related Escherichia coli Ff filamentous phages (f1, fd, and M13) have taken a fantastic journey over the past 60 years, from the urban sewerage from which they were first isolated, to their use in high-end technologies in multiple fields. Their relatively small genome size, high titers, and the virions that tolerate fusion proteins make the Ffs an ideal system for phage display. Folding of the fusions in the oxidizing environment of the E. coli periplasm makes the Ff phages a platform that allows display of eukaryotic surface and secreted proteins, including antibodies. Resistance of the Ffs to a broad range of pH and detergents facilitates affinity screening in phage display, whereas the stability of the virions at ambient temperature makes them suitable for applications in material science and nanotechnology. Among filamentous phages, only the Ffs have been used in phage display technology, because of the most advanced state of knowledge about their biology and the various tools developed for E. coli as a cloning host for them. Filamentous phages have been thought to be a rather small group, infecting mostly Gram-negative bacteria. A recent discovery of more than 10 thousand diverse filamentous phages in bacteria and archaea, however, opens a fascinating prospect for novel applications. The main aim of this review is to give detailed biological and structural information to researchers embarking on phage display projects. The secondary aim is to discuss the yet-unresolved puzzles, as well as recent developments in filamentous phage biology, from a viewpoint of their impact on current and future applications.

How Does Public Capital Affect Enterprise Technological Innovation Based on Empirical Evidence from Chinese Listed Companies

Public capital is an important force for promoting industrial agglomeration and enterprise technological innovation, and enterprise technological innovation is the core element in promoting green economic growth. To further reveal the influence mechanism of public capital on enterprise technological innovation, based on the data of A-share listed companies in China from 2007 to 2020, this paper uses the nonlinear moderating effect model and the intermediating effect model to verify the nonlinear influence and transmission mechanism of public capital on enterprise technological innovation. This paper discusses the influence and mechanism of public capital on enterprise innovation from the perspective of industrial agglomeration. The study finds that public capital has a significant role in promoting enterprise technological innovation. Moreover, economic public capital plays a greater role in promoting enterprise technological innovation than social public capital. Further analysis shows that the innovation effect of public capital is nonlinearly regulated by industrial agglomeration. In the initial stage of industrial agglomeration, the higher the degree of industrial agglomeration, the weaker the innovation effect of public capital; however, in the advanced stage of industrial agglomeration, the higher the degree of industrial agglomeration, the stronger the innovation effect of public capital. The nonlinear effect is realized by affecting the profits of enterprises. From enterprise heterogeneity, public capital has a significant role in promoting the technological innovation of non-state-owned enterprises but has no significant impact on the technological innovation of state-owned enterprises; public capital has a significant positive effect on the technological innovation of mid- and high-end technology enterprises, while its impact on the technological innovation of low-end technology enterprises is not significant. From the type of innovation output, public capital has a significant role in promoting enterprise green technology innovation, and the role of public capital in promoting enterprise green invention patents is greater than that of green utility model patents. This study provides a theoretical basis for government public capital investment decisions and empirical evidence for the sustainable development of enterprise technological innovation.

Perceived benefits of modern cooking technologies: a study of beneficiaries of Pradhan Mantri Ujjwala Yojana

PurposeThis paper examine beneficiary women's awareness of the harmful effects of traditional cooking fuels and the benefits of cleaner cooking fuel (LPG) in the Indian state of Haryana after the inception of Pradhan Mantri Ujjwala Yojana.Design/methodology/approachDescriptive statistics, factor analysis, confirmatory factor analysis, Mann–Whitney U test and Kruskal–Wallis H test were used for the data analysis.FindingsThe paper finds that the women of the scheduled caste were highly aware of the hazards of traditional cooking fuel. They perceived that the usage of LPG led to significant health and environmental improvements. However, the refilling was low among the respondents. So, the only low awareness was not the cause of the low refilling of LPG among Ujjwala beneficiaries.Research limitations/implicationsTechnological advancement, accessibility and successful adoption require convergence with socio-economic and institutional aspects. It was evident that focus on technology might not necessarily serve developmental purposes if it is not integrated correctly with socio-economic and institutional factors. These should have conversed with the household's needs, preferences, affordability, social structures, policy support and delivery mechanism, as it was observed that, in different cases, high-end technologies have limited access.Originality/valueThis study shows that the low awareness is not the barrier to the adoption of cleaner cooking technologies in India. So, the policymakers have to revive and further investigate the real cause of the low adoption of cleaner cooking technologies in India.
