Shandong, China’s largest agricultural province, generates a massive amount of agricultural waste each year, with corn stover being the predominant type. Although current agricultural waste management primarily involves sustainable practices carried out by professional companies, this study seeks to explore a simpler, more accessible method of handling stover waste. Guided by positivist theory and several experiments, a formula was developed, primarily composed of corn stover powder and natural substances such as glycerin. In this process, we designed and implemented four control experimental groups with water as the quantity used to investigate the influence of different material content in the formula. The resultant material was then subjected to property analyses, including tests on colouration, toughness, etc. Ultimately, the material was applied in a small-scale test as a raw material for an agricultural product packaging design. The study, rooted in sustainability, environmental protection, and the establishment of a local circular economy, fills the gap in current research of lacking design knowledge interventions.

Wavelength modulation-based tunable diode laser absorption spectroscopy (TDLAS/WMS) is widely used in various manufacturing processes. On the aseptic preparation filling production line, the seal quality of pharmaceutical glass vials should be strictly inspected in situ, where the 2 ^nd harmonic signal is usually selected for headspace residual oxygen measurement due to its prominent amplitude natures. While, higher-order harmonics still contain reliable concentration information but are often ignored. In this paper, we first design a laser injection signal with dynamic modulation depth and then propose a new methodology of multiple harmonic information fusion (MHIF), which is simple but promotes the mining of more effective concentration information from the absorption spectrum. Based on the fusion analysis results, an MHIF-guidance gas concentration inversion model is designed. To verify the performance of the proposed inversion model, a TDLAS/WMS-based residual oxygen detection platform is built. In this system, we use the harmonic signals from the 1 ^st to 8 ^th cycles together to perform precise measurement of the oxygen concentration in pharmaceutical glass vials. The results show that the stability of the new MHIF-based feature can exceed that of the traditional 2 ^nd harmonic features by 24.7%. Moreover, the new inversion model can increase the detection accuracy by over 10% compared to the traditional inversion model.

Although far away, the pandemic of 2019 has given rise to many thoughts towards people's lifestyles and attitudes. More and more people are getting used to working and studying at home, which has given rise to many inspirations for the development of technology related to the lifestyle. Studies have previously demonstrated that incorporating botanical decorations into living scenes can benefit people's mental and physical health. There are also many artists and scientists on this basis to explore the integration of plants and machinery development, trying to use the characteristics of plants to achieve the purpose of convenient people's life. "Biophilia" advocates the human instinct to be close to the natural world and defines the innate emotional connection between humans and other living things as 'pro-life'. By parametrically controlling the growth of plants to create furniture forms for people to use, this article tries to push the boundaries between living and non-living, natural and artificial, and computational and biological intelligence. The experimental method is adopted to precisely control the exposure of experimental plants to indoor environmental qualities such as water, sunlight, air movement, gravity, touch and media to produce tolerant porous shapes in their growth forms and then shape into furniture form. This has also been verified by previous studies that show the effectiveness and possibility of creating self-standing 3D structures by integrating computational design tools in designing with plant roots. In addition, this case also combines knowledge from disciplines such as biology and materials science to parametrically predict trends in the survival of plants as intelligent organisms and to explore the use of plant ecosystems in the construction of man-made landscapes by presenting the possibility of plant roots as sustainable materials and transport carriers. Products created so far include chairs and tables using plant roots. The paper details the process of designing parametric plant furniture and the product's effect pictures. The second half of the paper highlights the potential implications of this design technique. At the end of the article, the research explores the future direction of parametric plant design, i.e. the use as furniture while preserving the natural properties of plant growth, thus creating a new ecological cycle in future use. Overall, this study has been carried out with important implications for biological, sustainable, and environmental design. In addition to the current research, which is mainly concerned with the simple planting of space, this study goes further and explores the plasticity of plants themselves as controllable biomorphs. With the current trend of sustainable design, it is also worth looking at how ecologically sustainable and circular living spaces can be constructed. Finally, this research will also enrich the diversity of human living spaces with tactile sensory and interactive properties that can be further developed and applied to the health and education sectors in the future, aiming to improve the well-being of the inhabitants.
