Abstract Internal thermal mass, such as furniture and partitions, plays a crucial role in enhancing building energy efficiency and indoor thermal comfort by passively regulating temperature fluctuations. However, the irregular geometry of these elements poses a significant challenge for accurate modeling in building energy simulations. This study addresses this gap by developing a rigorous analytical model that idealizes internal thermal mass as a sphere, thereby capturing multi-directional heat conduction effects that are neglected in simpler one-dimensional slab models. The transient heat conduction within the sphere is solved analytically using Duhamel’s theorem for three representative indoor air… More >

Abstract The current global shortage of oil resources and the pollution problems caused by traditional barrier materials urgently require the search for new substitutes. Biodegradable bio-based barrier materials possess the characteristics of being renewable, environmentally friendly, and having excellent barrier properties. They have become an important choice in fields such as food packaging, agricultural film covering, and medical protection. This review systematically analyzes the design and research of this type of material, classifying biobased and biodegradable barrier materials based on the sources of raw materials and synthesis pathways. It also provides a detailed introduction to the More >

Abstract The paper briefly describes the methodology for studying the temporal characteristics of near-IR photodiode structures under the influence of pulsed radiation from a semiconductor laser with a wavelength of 1100 and 1320 nm. The results of studying the response time of multilayer photosensitive Au-nCdS-nSi-pCdTe-Au and Au-nInP-nCdSνGaAs:O-Au structures with potential barriers are presented. It has been experimentally shown that the structures under study are not inferior in response time to known analogs based on gallium arsenide and silicon heterostructures, and can also be used in a wide optical range.

Abstract Based on the experimental data, the results of the study of photoelectric and gain characteristics of modified multi-barrier photodiode Au-nCdS-nSi-pCdTe-Au structures are presented, which are obtained by the method of vacuum evaporation in a quasi-closed volume by sputtering cadmium sulfide and cadmium telluride layers on a silicon substrate with a specific resistance of 607.47 Ohm⋅cm. It is shown that the structures in the passing direction of the current at low illumination levels operate as injection photodiodes, and also the optical spectral range (0.3÷0.95 μm) covers from the nSi-pCdTe-Au side and (1.0÷1.4 μm) from the Au-nCdS-nSi More >

Abstract The use of wood-polymer composites (WPC) based on a polymer matrix and wood filler is a modern, environmentally friendly direction in material science. However, untreated wood filler exhibits poor adhesion to hydrophobic polymers due to its hydrophilic lignocellulose fibers. To address this, ozone treatment is employed to enhance compatibility, reduce water absorption, and regulate biodegradation rates. This study investigates the hypothesis that ozone modification of wood filler improves adhesion to thermoplastic starch, thereby enhancing the physico-mechanical properties and controlled biodegradation of WPCs under compost conditions. A comprehensive analysis was conducted on composites containing untreated and… More >

Abstract Magnolia officinalis is a perennial deciduous tree that has medicinal properties. The AP2/ERF gene family has a number of roles in long-term growth and metabolism. The expression of this function varies with the growth period. In this work, based on the transcriptome data of Magnolia officinalis, the complete coding gene of Magnolia officinalis was obtained, and the corresponding protein sequence was retrieved from NCBI and compared with the model plant Arabidopsis thaliana. After screening, 75 protein sequences from the AP2/ERF gene family were identified and called MoAP2/ERF1–MoAP2/ERF75, followed by bioinformatics analysis. 75 AP2/ERF gene families were found and classified into four… More >

Abstract Human tissues and organs exhibit not only intricate anatomical architectures but also spatially heterogeneous distributions of elastic modulus—for example, between cancellous and cortical bone, across the epidermis, dermis, and subcutaneous layers, and between healthy and fibrotic liver tissues. Conventional biomaterials often fail to replicate such mechanical heterogeneity, thereby limiting their capacity to recreate biomimetic physiological microenvironments essential for applications like tissue regeneration and disease modeling. Meta-biomaterials, artificially engineered through the rational structural design of continuous materials, have emerged as a promising class of materials owing to their highly tunable mechanical and biological properties. These attributes… More >

Abstract In modern engineering, situations that require vibration reduction often come with specific pressure requirements. Mechanical metamaterials have the advantages in mechanical loading and low-frequency band gap vibration reduction. To ensure that the structure has a wide and low-frequency band gap while having a pressure resistance, a two-dimensional triangular concave negative Poisson's ratio structure with strong pressure resistance is introduced. The internal structure is designed according to the principle of local resonance. The band structure and intrinsic modes of the two-dimensional triangular concave model are calculated by the finite element method through simulation software. The band… More >
