摘要：
The photocatalytic degradation of formaldehyde by graphite-like C(3)N(4) is one of the most attractive and environmentally friendly strategies to address the significant threat to human health posed by indoor air pollutants. Despite its potential, this degradation process still faces issues with suboptimal efficiency, which may be attributed to the rapid recombination of photogenerated excitons and the broad band gap. As a proof of concept, a series of graphite-like C(3)N(4)@C(60) composites combining graphite-like C(3)N(4) and C(60) was developed via an in situ generation strategy. The obtained graphite-like C(3)N(4)@C(60) composites exhibited a remarkable increase in the photocatalytic degradation efficiency of formaldehyde, of up to 99%, under visible light irradiation, outperforming pure graphite-like C(3)N(4) and C(60). This may be due to the composites' enhanced built-in electric field. Additionally, the proposed composites maintained a formaldehyde removal efficiency of 84% even after six cycles, highlighting their potential for indoor air purification and paving the way for the development of efficient photocatalysts.
摘要：
The issue of white pollution has gained more attention in recent years on a global scale. Using fast-growing wood and plastic waste to produce wood-plastic composites can effectively increase the plastic recovery rate while relieving the pressure of structural shortage of wood resources in many countries. Hence, this study demonstrates an innovative approach to prepare a good-quality wood-plastic laminates based on wood-plastic composites. Poplar veneer was first pretreated with microwave-assisted acetic acid followed by a one-step thermal forming process with powdered polyethylene (PE) to produce the glue-free wood-plastic laminates. It was found that the pre-treated composite has a tensile strength of up to 280 MPa and specific strength of up to 205.98 kNm/kg. The excellent mechanical properties can be attributed to the mechanical interlock be-tween wood fibre and polyethylene, plus the closer bond among the fibres induced by cell wall collapses during hot-pressing. Furthermore, the water contact angle of the composite surface remains at about 84 degrees after 10 s. That suggests its good surface waterproof performance which is attributed to the partial degradation of hemicellulose during the pretreatment and the coating of wood fiber with polyethylene. Overall, we have developed glue-free, high-strength, and heat -resistant wood-plastic laminates applicable to interior furniture and outdoor building facilities. This is imperative for protecting the ecological environment and reducing the pressure on structural shortages of wood resources worldwide.

Featured Application Using Structural Design to Reduce Product Development Costs and Increase Patient Active Rehabilitation Motivation.Abstract In order to meet the diversified rehabilitation needs of people, it is necessary to design a product for the active rehabilitation of patients. Existing rehabilitation chairs use intelligent massage, which can cause problems such as large massage areas, inability to massage locally, large chair size, and inability to meet the continuous use of the damaged parts. In this paper, the modular design method and multi-layer evaluation method are used to solve the problems related to rehabilitation chairs. The authors use the questionnaire survey method and the functional technology matrix method to determine the functional requirements of the rehabilitation chair, and then use the multilevel evaluation methods, including the AHP method, entropy weight method, and grey correlation analysis, to optimize the functional solutions of the rehabilitation chair, and finally obtain a chair for the rehabilitation of patients with upper and lower limb disorders. Problems such as the generalization of rehabilitation scope and non-durable use of components were solved, and the purpose of active exercise was achieved. This study verifies that the use of the multilevel decision evaluation method can effectively improve the efficiency of program decision-making and provides a theoretical and practical basis for the design of similar products.

摘要：
In the context of high-quality development, environmental issues are being paid more and more attention to, and the release of free formaldehyde has become a major problem that needs to be solved. Glueless plywood mainly adopts natural substances as raw materials, without adding chemical products, such as resin adhesives, and it does not contain harmful substances, such as formaldehyde. Glueless plywood is a green product that causes no pollution in the environment and no harm to the human body. In this study, the corresponding weak-phase components in boxwood were pre-delivered by an acidic environmental treatment, and the high-temperature and high-pressure compacting process produced a glueless boxwood panel with excellent water resistance and mechanical properties, while remaining environmentally friendly.

摘要：
In light of the uprising global development on sustainability, an innovative and environmental friendly wood-based material derived from natural pinewood has been developed as a high-performance alternative to petrochemical-based materials. The wood-based functional material, named as BC-CaCl2, is synthesized through the coordination of carboxyl groups (-COOH) present in pinewood with calcium ions (Ca2+), which facilitates the formation of a high-density cross-linking structure through the combined action of intermolecular hydrogen bonds. The as-prepared BC-CaCl2 exhibits excellent tensile strength (470.5 MPa) and flexural strength (539.5 MPa), establishing a robust structural basis for the materials. Meanwhile, BC-CaCl2 shows good water resistance, thermal conductivity, thermal stability, UV resistance, corrosion resistance, and antibacterial properties. BC-CaCl2 represents a viable alternative to petrochemical-based materials. Its potential application areas include waterproof enclosure structure of buildings, indoor underfloor heating, outdoor UV resistant protective cover, and anti-corrosion materials for installation engineering, and so forth.image This study reports an efficient process for facile fabrication of high-performance, sustainable wood-based structural functional materials based on natural pinewood.
