Antifreeze protein-based ultrastretchable and highly sensitive hydrogel for human-machine interaction

Intelligent and convenient human–computer interfaces realize efficient and close cooperation between people and the digital world. As windows of human–machine interaction (HMI), sensors directly determine the ability and quality of acquired signals and the utilization potential of HMI systems. However, it still remains challenging to develop antifreeze hydrogel sensors with freeze-resistant properties while avoiding the loss of other properties as much as possible to achieve stable HMI applications in low-temperature environments. Here, we present an Agar/PAAm dual-network hydrogel (Na+-Agar/PAAm-AFP) doped with both antifreeze protein (AFP) and sodium chloride (NaCl), which exhibits excellent antifreeze capability (−20 °C). The hydrogel integrates transparency (>90%), ultra stretchability (up to 2100%), good adhesion properties to metal, glass, and plastic, high electrical conductivity (3.41 S m−1), high sensitivity (GF = 10.23), and non-irritating to the skin. The hydrogel can be used for monitoring daily activities and glove-based HMI systems for intelligent control. In addition, based on this hydrogel, we have successfully developed an interactive system for real-time information transfer over long distances. It is expected to provide better health management monitoring in several fields and also help to advance the development of innovative and IoT technologies.

The driving effect of technological innovation on green development: From the perspective of efficiency

Green development is considered to be an effective way to achieve win-win between economy and environment, and technological innovation is the core driving force of green transformation development. High-tech industries are the core industries of industrial technology and economic development, and their technological innovation ability and green development level are important supports for optimizing the national industrial structure and promoting the green transformation of industries. Therefore, based on the concept of innovation and green development, this paper analyzes the industrial development rule from the perspective of the interaction mechanism between technological innovation and green development, to provide theoretical reference for the design of corresponding development strategies and planning. Hence, NSBM model is constructed to evaluate the efficiency of multi-stage technology innovation and deconstruct the evolution law of technology innovation value chain of high-tech industry. Secondly, GML model is used to evaluate green total factor productivity and clarify the green and high-quality development status of high-tech industry. Finally, the truncated regression model is constructed to analyze the factors affecting the external environment of green transformation development. The results indicate that the upgrading of technology innovation value chain is conducive to promoting green transformation development.

Photoinduced charge generation of nanostructured carbon derived from human hair biowaste for performance enhancement in polyvinylidene fluoride based triboelectric nanogenerator

Carbon nanostructures derived from human hair biowaste are incorporated into polyvinylidene fluoride (PVDF) polymer to enhance the energy conversion performance of a triboelectric nanogenerator (TENG). The PVDF filled with activated carbon nanomaterial from human hair (AC-HH) exhibits improved surface charge density and photoinduced charge generation. These remarkable properties are attributed to the presence of graphene-like nanostructures in AC-HH, contributing to the augmented performance of PVDF@AC-HH TENG. The correlation of surface morphologies, surface charge potential, charge capacitance properties, and TENG electrical output of the PVDF composites at various AC-HH loading is studied and discussed. Applications of the PVDF@AC-HH TENG as a power source for micro/nanoelectronics and a movement sensor for detecting finger gestures are also demonstrated. The photoresponse property of the fabricated TENG is demonstrated and analyzed in-depth. The analysis indicates that the photoinduced charge carriers originate from the conductive reduced graphene oxide (rGO), contributing to the enhanced surface charge density of the PVDF composite film. This research introduces a novel approach to enhancing TENG performance through the utilization of carbon nanostructures derived from human biowaste. The findings of this work are crucial for the development of innovative energy-harvesting technology with multifunctionality, including power generation, motion detection, and photoresponse capabilities.

Coupled Coordination and Drivers of Green Technology Innovation and Carbon Emission Efficiency

The coupled and coordinated development of green technology innovation and carbon emission efficiency in the Yangtze River Economic Belt is crucial for its realization of green and low-carbon transformation. Based on the panel data of the Yangtze River Economic Belt from 2011 to 2021, the comprehensive evaluation levels of green technological innovation and carbon emission efficiency were measured, and the coupling degree of coordination model and panel Tobit model were constructed to empirically analyze the coupling degree of coordination and driving factors of the two. The results show that, overall, the comprehensive evaluation value of green technology innovation level in the Yangtze River Economic Zone shows an upward trend; the value of carbon emission efficiency first rises and then falls. From the perspective of spatial distribution, both of them present the characteristic of “high in the east and low in the west”. The coupling coordination degree shows a growing trend and initially realizes the basic coordination. The coupling degree of coordination shows a significant negative correlation between the energy structure and the coupling degree of both of them, while urbanization level, environmental regulation, industrial structure, level of economic development, degree of openness, and labor level all show a significant positive correlation.

Microfluidics-Based Technologies for the Assessment of Castration-Resistant Prostate Cancer.

Castration-resistant prostate cancer remains a significant clinical challenge, wherein patients display no response to existing hormone therapies. The standard of care often includes aggressive treatment options using chemotherapy, radiation therapy and various drugs to curb the growth of additional metastases. As such, there is a dire need for the development of innovative technologies for both its diagnosis and its management. Traditionally, scientific exploration of prostate cancer and its treatment options has been heavily reliant on animal models and two-dimensional (2D) in vitro technologies. However, both laboratory tools often fail to recapitulate the dynamic tumor microenvironment, which can lead to discrepancies in drug efficacy and side effects in a clinical setting. In light of the limitations of traditional animal models and 2D in vitro technologies, the emergence of microfluidics as a tool for prostate cancer research shows tremendous promise. Namely, microfluidics-based technologies have emerged as powerful tools for assessing prostate cancer cells, isolating circulating tumor cells, and examining their behaviour using tumor-on-a-chip models. As such, this review aims to highlight recent advancements in microfluidics-based technologies for the assessment of castration-resistant prostate cancer and its potential to advance current understanding and to improve therapeutic outcomes.

ОСНОВНЫЕ ТРЕНДЫ РОСТА РЕГИОНАЛЬНОГО СЕЛЬСКОГО ХОЗЯЙСТВА: ОТ ОБЪЕМОВ К УСТОЙЧИВОСТИ

The strategic task until 2030 for the agro-economic systems of the country and its regions is to increase the average annual growth rate of volumetric indicators of agricultural production to 3%, which is twice as high as the achieved value. To achieve this aim, it is necessary to develop and implement effective mechanisms to smooth out the abrupt growth of production volumes and ensure the sustainable development of agricultural sectors. The development of the agricultural sector of the Republic of Tatarstan shows positive trends in the growth of volumetric indicators of production over the past five years. The volume of gross agricultural output in the region increased with an annual growth rate of 21.62 billion rubles. At the same time, the volume of production growth in the crop and livestock sectors amounted to 11.11 and 10.49 billion rubles, respectively, which demonstrates the uniform development of the two main industries. The growth in volumetric indicators of product production is mainly due to the intensification of production processes, the introduction and development of innovative technologies. Along with this, abnormal weather conditions have a negative impact on the process of sustainable development of agriculture, as evidenced by the results of 2021, when the total production volume was only 80.1% of the previous year’s level, and crop production decreased by 38.7%. The identified trend once again emphasizes the need to search for adaptive methods of farming in accordance with climate change by moving at a more intensive pace to the creation of drought-resistant varieties, the development of moisture-saving technologies and the active implementation of reclamation measures. Livestock farming is developing at a more sustainable pace, although there is a decline in the numbers of certain animal species. However, this process does not affect production volumes due to increased animal productivity. The industry is in the process of gradually replacing low-productive animals with highly productive breeding stock. To transition to sustainable development of agriculture in the republic, it is necessary to continue work on adapting technological processes to climate change, creating and introducing new varieties, developing genetic technologies for animal breeding, using digitalization and robotization of the industry.

Reverse supply chain decisions with online and offline dual recycling channels considering consumer fairness concerns and channel preference

Online recycling is becoming more prevalent as a result of the quick development of innovative technologies to enhance the recycling system. Based on consumer fairness concerns and channel preferences, we establish an online and offline dual-recycling channel reverse supply chain model in which a processor dominates and a recycler follows according to Stackelberg game theory and investigates the impact of two consumer’s behavioral preferences upon supply chain decisions. The results show that: (1) for the game leader, the impact of consumer fairness concerns is greater than that of channel preference; (2) for the game follower, the impact of channel preference is greater than that of consumer fairness concerns; (3) entrusting the recycler to collect can help the leader reduce profit losses caused by consumer fairness concerns.

Global economic policy uncertainty and renewable energy demand: Does environmental policy stringency matter? Evidence from OECD economies

Existing literature recommends the essential role of renewable energy consumption (REC) in achieving environmental sustainability. Although prior works have investigated the significant factors of REC, the effect of green environmental policies remains largely understudied, particularly in OECD countries. Therefore, this study specifically examines the role of environmental policy stringency (EPS) in enhancing (or diminishing) REC in 27 OECD economies between 2000 and 2019. Furthermore, we aim to specify the determinants of REC and investigate whether EPS could help moderate the relationship between global economic policy uncertainty (GEPU) and REC. To accomplish this, we employ both the fixed effects and panel quantile estimation methods. The findings underline that EPS has a positive and significant impact on REC, indicating that stricter green environmental policies lead to encouraging REC. Besides, the findings show that EPS has a beneficial role in lessening the negative effect of GEPU on REC, and its negative effect on REC is more moderated as moves from environments with low EPS to high EPS. The results also underscore that financial market development, FDI, remittances, technological innovation, and economic development positively promote REC whereas CO2 and natural resources rents have a detrimental impact. The findings are significant and a wide range of policy suggestions is recommended to governments, policymakers, and regulators to attain the energy and environmental sustainability targets set out in SDG 7 and SDG 13, respectively.

Plastic waste recycling in additive manufacturing: Recovery of polypropylene from WEEE for the production of 3D printing filaments

The inefficient management of wastes recovered from electric and electronic apparatuses (the so-called WEEE or e-waste) has become a severe global concern in the last years, since the indiscriminate accumulation of wastes containing hazardous material poses serious risks for the environmental, as well as for the human health. Despite the continuous development of innovative and efficient technologies for the mechanical recycling of WEEE plastics, the effective re-utilization of these fractions is often limited by their poor value-added. In this work, we propose a strategy for the valorization of a typical WEEE plastic stream recovered from small appliances (mainly composed on polypropylene filled with talc particles) through the formulation of filaments suitable for Fused Filament Fabrication (FFF) 3D printing processes. Preliminary spectroscopic analyses on the WEEE plastics allowed separating the sample in two streams, according to the different content of talc. Both streams were first characterized from a rheological point of view, aiming at assessing their 3D printability. Then, the mechanical properties and the morphology of the filaments (obtained after a close optimization of the extrusion conditions) were evaluated; the obtained results indicated the achievement of a regular geometry and mechanical properties comparable to those of commercial filaments. Finally, 3D printed specimens showed a satisfactory quality in terms of resolution and definition, demonstrating the possibility of profitably enhancing the value-added of WEEE plastics, using them as feedstock to produce sustainable 3D printing filaments.

System for evaluating medical technologies in military healthcare

Modern challenges and threats, as well as unprecedented sanctions pressure on the Russian Federation, have contributed to the intensification of research both on the development of innovative medical technologies and on expanding the range of use of existing ones. At the same time, on the one hand, there is an increase in incoming proposals for the use of various medical technologies in military healthcare, and on the other hand, the need to ensure accessibility and improve the quality of medical care for military personnel and other cate- gories of assigned contingents is rapidly increasing. At the same time, in con- ditions of limited resources, the level of requirements for justifying the need to introduce one or another medical technology into the activities of military medical organizations and other medical units of the Armed Forces of the Rus- sian Federation naturally increases. All this predetermines the relevance of the development of a departmental system for assessing medical technologies for effective information support for making rational management decisions. The study examined the main directions of development of the medical tech- nology assessment system in military healthcare. In particular, goals and objectives are defined, the main aspects and possible forms of organizing a departmental system for assessing medical technologies are substantiated. The main elements of the basic model for assessing medical technologies in military healthcare are identified. In addition, the characteristics of the in- formation system for assessing medical technologies in military healthcare are given, its main components are given, as well as the expected effects of implementation. The implementation of the departmental concept for assessing medical tech- nologies in the main directions of development presented in the article on the basis of a specialized information system will not only help increase the availability of effective and safe medical technologies, but also the rational use of funds and other military healthcare resources. In addition, taking into ac- count the results of departmental assessment of medical technologies at the state level will serve as the basis for the formation of priority directions for the strategic development of the domestic medical and pharmaceutical industry in the interests of national defense and state security.

Exploring the Path of Cultivating College Students’ “Innovation and Entrepreneurship” Ability under the Integration of Research and Teaching

The integration of research and teaching is an important measure to solve the problem of separation and even contradiction between education and scientific and technological research. The dialectical and unified theoretical mechanism among education, technology, and talent can promote the integration of research and teaching from three aspects: education and teaching, technological innovation, and talent cultivation, in response to the problems and difficulties in the current “innovation and entrepreneurship” ability of college students. This can promote the improvement of college students’ “innovation and entrepreneurship” ability.

Experimental investigation on a lightweight, efficient, counter-rotating fan with and without boundary layer ingestion

AbstractThe experimental investigations on the counter-rotating CRISPmulti fan with boundary layer ingestion are presented in this paper. The Counter Rotating Integrated Shrouded Propfan (CRISP) was designed, aerodynamically optimized and manufactured in lightweight material by the German Aerospace Center (DLR). The main task was to maximize the aerodynamic efficiency under restricted static, dynamic and acoustic properties of the blade designed with lightweight carbon-fiber material and to apply it as a demonstrator for the development of a new innovative blade manufacturing technology. The rotors were manufactured at the DLR Institute of Structures and Design and tested on the Multi-stage 2-shaft Compressor Test Facility (M2VP) at the DLR Institute of Propulsion Technology. The instrumentation enabled the measurement of the aerodynamic, static, dynamic and acoustic behavior of the fan. In general, the targets of the experimental investigation were to validate the optimization results, the numerical calculational methods and the acoustic tools. Additionally, inlet distortion measurements were carried out on the fan rig to investigate the effect of the boundary layer ingestion on a real counter-rotating propfan. A radially traversable disturbance body, designed to simulate the boundary layer of the aircraft fuselage on an aircraft architecture with embedded engines, enables a comprehensive measurement program to be carried out for both undisturbed and disturbed inflow.

Local environmental goal constraint intensity and corporate ESG performance: An empirical observation based on China

Improving Environmental, Social, and Governance (ESG) performance has become an important international standard for measuring green and sustainable corporate development. This paper empirically finds that increasing local environmental goal constraint intensity significantly improves the ESG performance of heavy polluters based on data from Chinese A-share heavily polluting companies from 2012 to 2021. Mechanism analysis suggests that imposing local environmental goal constraints can improve ESG performance by promoting the development of green technological innovation and increasing media attention. This effect is more evident in non-state-owned, high-market value pressure companies, and cities with lower fiscal revenues and more industrial output in GDP. These findings hold significant implications for policymakers who seek to propose more effective incentive strategies.

Public procurement in the system of creating conditions for the development of deep tech innovations in Ukraine

Problem setting. The European Union has long been paying special attention to stimulating innovative activity through the use of public procurement. This is emphasized both in EU directives in the field of public procurement and in specific program documents regarding the development of innovations in the European Union, in particular the new wave of deep technological innovations. At the same time, in Ukraine, the public procurement institute is currently used only as a tool for saving public funds and preventing corruption. Thus, there is a need to study the issue of public procurement as a means of state regulation of innovations in general, as well as a possible tool for stimulating deep technological innovations in Ukraine, including, considering the experience of the EU, in particular, and for the post-war reconstruction of our state. Analysis of recent researches and publications. Some separate aspects of the issue of innovation stimulation through the mechanism of public procurement were given attention in the works – V.K. Malolitneva, L.O. Berezovska, A.V. Kyrychenko, S.R. Karpenko and others. At the same time, the issue of stimulating a new wave of deep tech innovations, using the instrument of state procurement, requires a more detailed study as a separate phenomenon, including in the aspect of harmonizing Ukrainian legislation with EU directives in the field of public procurement. Purpose of the research is to determination of the place of the institution of public procurement as a tool for stimulating the development of deep tech innovations in Ukraine, as well as an analysis of the legal support for the use of public procurement as a regulation of innovative activity in the European Union and in Ukraine, including in the aspect of the need to harmonize Ukrainian legislation with EU rights. Article’s main body. The article is devoted to the study of the issue of legal regulation of public procurement as a means of state regulation aimed at stimulating innovative activity in the European Union. The value of state purchases of ready-made innovative solutions, as well as research and development works, the result of which can be innovative products, is analyzed. The main types of procurement of innovations provided for by European regulatory acts are given. It has been established that the riskiness and capital intensity of deep tech innovations indicate that the main driver, catalyst, and initiator of their development can be the state, using the mechanism of the state order. The issue of legal regulation of the use of the public procurement tool to stimulate the development of deep technological innovations in Ukrainian legislative acts has been investigated. The main legal problems of using such a tool in our country are presented, including in the aspect of harmonization of legislation in the field of public procurement with relevant EU directives. Conclusions and prospects for the development. In Ukrainian legislation, despite its harmonization and adaptation to EU law, there are no special provisions regarding procurement of innovations. At the same time, in the European Union there is a thorough and consistent approach, according to which public procurement an important and effective tool for the development of innovations, in particular, deep tech innovations. Ukraine needs more careful consideration of this practice, since post-war reconstruction requires special innovative solutions that can be found, including, with the use of public procurement.
