Published: May 2024

In 2023, the State Council of China issued the "New Era of Green Development in China" white paper, which emphasizes the vigorous promotion of photovoltaic base construction in desert, Gobi, and desert areas. Conventional fixed solar power generation systems have relatively low light utilization efficiency, and light-tracking products based on photoelectric tracking lack the ability to resist environmental interference, making them unsuitable for high-precision tracking in complex environments. To address these issues, this project designs a foldable solar photovoltaic automatic tracking device with self-cleaning functionality. The device employs a control scheme that combines photoelectric tracking with sun path trajectory tracking to achieve high-precision solar tracking. Experimental results show that this device improves power generation by 34.8% compared to fixed solar power generation systems. Under specific conditions, the photovoltaic panels can automatically retract and self-clean, enhancing the device's environmental adaptability. To enable remote monitoring and control of the equipment, the device is equipped with Internet of Things (IoT) technology and a cloud monitoring platform.

Authors: Ren Jianing
Published: May 2024

Continuous consumption of non-renewable resources generates a mass of carbon emissions which is blamed for global warming. Consequently, the research of high power and green electric vehicles has brought to the marketing. Therefore, in this paper, four commercialized cathode materials used prevalently in lithium-ion batteries, layered LiCoO2, spinel LiMn2O4, and olivine LiFePO4, and layered LiNi1-x-yCoxMnyO2, and the application of nanotechnology in improving electrode performance are introduced. Due to the different crystal structures of olivine, layered, and spinel, the corresponding lithium-ion diffusion path is 1-dimensional, 2-dimensional, and 3-dimensional, which is closely related to their electrode performance. The utilization of nanotechnology benefits the electrode performance to a large extent because of the shortening of lithium-ion diffusion paths as a result of increasing surface-to-volume ratio. Electrochemical properties including energy density, rate capability, capacity retention, electronic conductivity, and cycling performance are all enhanced through the application of nanorods, carbon nanotubes, reduced graphene oxides, etc.

Authors: Hao Ran
Published: May 2024

In the development of nanotechnology, responsive self-assembly has been an important research theme. Responsive self-assembly is a technique where nanoparticles form structures in response to external stimuli like temperature and light. Thermo-responsive and photo-controlled self-assembly processes are outstanding compared with traditional methods, and theyve been applied in drug delivery and smart surfaces. Yet, the two processes still have their own challenges in practical applications. This review explores both techniques for explaining how these external stimuli work and the role of nanomaterial properties in the processes. Then it dives deep into their applications, specifically focusing on their strengths and challenges. Thermo-responsive and photo-controlled self-assembly are eco-friendly and reversible, ensuring their wide applications in various conditions. However, thermo-responsive materials, notably UCST-based polymers, are limited in scope, sensitive to the environment, and extremely expensive, while the effectiveness of the photo-controlled assembly process is limited by certain light conditions. Future research should focus on exploring their potential and overcoming the challenges.
The application of nanotechnology in preventing photoaging and photodamage
Authors: Bao Xiangtian
Published: May 2024

Skin is the first protecting us barrier from the external environment. Overexposure to sunlight, containing harmful ultraviolet radiation (UVR), may lead to photoaging. Prolonged exposure to UVR produces a notable volume of reactive oxygen species (ROS) that can exacerbate the degradation of the skin's essential structural proteins, including collagen and elastin. This interference may result in conditions like dermal solar elastosis and extracellular matrix (ECM) remodelling. UVR can cause different types of skin damage, including direct and indirect DNA damage, oxidative stress, and immune suppression. These effects can have severe consequences and lead to various skin problems, such as melanoma, squamous cell carcinoma (SCC), and basal cell carcinoma (BCC) skin cancers. In this review, we will examine how nanotechnology can be used in the prevention and treatment of skin aging and damage resulting from UVR exposure. Nanotechnology offers potential solutions for safeguarding the skin against UVR's harmful effects and repairing resulting damage.

Published: May 2024

Artificial muscle, as a new technology, has a broad application prospect and market in the future, which is more effectively applied to the medical repair of human muscle damage, enhance the strength performance of human muscle, and enrich the function of artificial robots. Nanotechnology is also a high-precision technology that can be added to artificial muscles to make expansion and contraction more reliable. Currently, nanotechnology is constantly innovating in artificial muscles. There have been examples of using artificial muscles to add touch systems for real-time interaction and temperature changes, as well as combining sacrificial coordination keys with mechanical training processes to allow artificial muscles to bear more than their own multiple weights. Carbon catheters using nanotechnology have been shown to contract by as much as 20%. However, while focusing on enhancing the performance of artificial muscles, the bionic ability of the material itself has been neglected, and the elasticity and stretch of the muscle is a major difficulty. Therefore, there are still some shortcomings and areas that can be improved in this field. In this paper, we discuss how to use carbon conduit nanotechnology to strengthen artificial muscles, which provides effective reference materials for human beings to better understand the application of artificial muscle nanotechnology.

Spatio-temporal and causal analyses of "black summer" fires based on remote sensing satellites
Authors: Chen Xiyuan
Published: May 2024

Wildfires are a common natural disaster that threatens the environment, the economy, the climate, and even human life. It is therefore important to monitor the occurrence of fires to understand how they start, what causes them, and how they can be better prevented. Fires occur throughout the year in Australia, and 2019-2020 saw an unprecedented black summer of fires. These fires have caused tens of thousands of animal and plant deaths, massive property damage, and many casualties. Therefore, it is more meaningful to study a typical case like Australia as a research object. In this paper, by applying Arcgis to MODIS fire point data, it is possible to analyze them in time and space. The causes are also analyzed through the impact of Sentinel-2. The results show that the initial phase of the fires is from July to October 2019, peaking in December 2019 and starting to decline in mid-January 2020. Most of the fires were concentrated along the coastline, with fewer in the west. This is thought to be related to the classification of vegetation cover and rainfall in Australia.
Complex Elbow Fracture-Dislocations: An Algorithmic Approach to Treatment
Authors: Meyer Maximilian A. , Leversedge Fraser J. , Catalano Louis W. , Lauder Alexander
Published: May 2024

Elbow stability arises from a combination of bony congruity, static ligamentous and capsular restraints, and dynamic muscular activation. Elbow trauma can disrupt these static and dynamic stabilizers leading to predictable patterns of instability; these patterns are dependent on the mechanism of injury and a progressive failure of anatomic structures. An algorithmic approach to the diagnosis and treatment of complex elbow fracture-dislocation injuries can improve the diagnostic assessment and reconstruction of the bony and ligamentous restraints to restore a stable and functional elbow. Achieving optimal outcomes requires a comprehensive understanding of pertinent local and regional anatomy, the altered mechanics associated with elbow injury, versatility in surgical approaches and fixation methods, and a strategic rehabilitation plan.

Иранские сады, известные как Чахарбаг, являются символом рая. Садовый дискурс развился и процветал в период Сефевидов (1501–1736 гг.) и оказал значительное влияние на многие виды искусства, включая ковроткачество. К этому же времени относят появление особого типа садового ковра под названием «чахарбаг». Иранские ковры стали своеобразной гетеротопией иранского сада. Они не только повторяют ландшафтную структуру, но и отражают важные концептуальные аспекты иранского садового искусства.

Iranian gardens, known as Chaharbagh, are symbols of paradise. Garden discourse developed and flourished during the Safavid period (1501–1736) and had a significant influence on many arts, including carpet weaving. The appearance of a special type of garden carpet called Chaharbagh dates back to this time. Iranian carpets have become a kind of heterotopia of the Iranian garden. They not only follow the landscape structure, but also reflect important conceptual aspects of Iranian garden art.

FELT IN INTERIOR DESIGN: MODERN REINVENTION OF TRADITIONAL TECHNOLOGY
Authors: Карпова Е.А.
Published: May 2024

Высокое развитие техники валяния войлока и его широкое применение у кочевых народов начиная с древних времен подтверждены археологическими находками. Войлочные изделия служили для покрытия, утепления и украшения передвижных и стационарных жилищ. В XX в. войлок почти перестал использоваться в быту. С 1970-х гг. профессиональные художники и дизайнеры в России и за рубежом заинтересовались декоративными свойствами войлока. Они обращаются к технологии войлоковаляния для создания декоративных панно, ковров, артобъектов, перегородок, мебели и осветительных приборов. Войлочные предметы дизайна выполняются в традиционной технике и при помощи современных методов.

The high development of felting technique and its widespread use among nomadic peoples since ancient times, have been confirmed by archaeological finds. Felt products were used to cover, insulate and decorate mobile and stationary dwellings. In the 20th century, felt almost ceased to be used in everyday life. Since the 1970s, professional artists and designers in Russia and abroad have become interested in the decorative properties of felt. They turn to felting technique to create decorative panels, carpets, art objects, partitions, furniture and lighting fixtures. Felt design objects are made using traditional techniques and modern methods.
