Sound absorption, structure and mechanical behavior of konjac glucomannan-based aerogels with addition of gelatin and wheat straw

Antiviral activity of salt-coated materials against SARS-CoV-2

“…Although we did not test this as part of this study, previous work suggests that a similar biomass aerogel had a low filtration resistance [16]. Additionally, although the pore size of biomass aerogels is large [17], we have previously showed that the overlapping network of pores creates a network that should block most viruses [17]. In short, in this study we have shown that spray coating of different types of fabric used in making facemasks provides potent antiviral properties against SARS-CoV2 and can be used as a fast and non-expensive method for developing more effective personal protective equipment against respiratory viruses.…”

“…The use of the biomass aerogels, in particular, will be a key area of future study. We previously reported on the biophysical and filtration properties of similar biomass aerogels to those used in this study [16,17]. One concern, for example, would be the breathability of novel facemask materials, such as the biomass aerogel [12].…”

“…For the facemask (KMD Company), the inner and outer layers are non-woven fabric and the middle layer is melt-blown fabric. A similar biomass aerogel to the one used in this study has been previously reported [16,17]. Surfaces were imaged using a scanning electron microscope (JEOL LV6060) and a lab-scale RS PRO USB digital microscope.…”

Carbon-Sequestration Straw Cellulose-Aerogel Gradient Thermal Insulation Material

“…Wheat straw, a readily available agricultural waste product, has recently gained substantial recognition for its potential to mitigate carbon emissions within the construction industry. − This versatile crop residue, remaining in abundance after the wheat harvest, emerges as a sustainable and environmentally friendly resource for the sequestration of carbon dioxide, a prominent contributor to the ongoing challenge of climate change. Furthermore, the incorporation of agricultural wheat straw into aerogel materials has shown significant promise. , In this context, wheat straw’s cellulose network plays a pivotal role in enhancing the mechanical strength and durability of aerogel/cellulose composites, while the aerogel itself serves as the primary agent in lowering the thermal conductivity of these innovative materials. , This synergy between wheat straw and aerogel opens up new avenues for the development of thermal insulation materials that are not only eco-friendly but also highly efficient in reducing heat transfer. As we continue to seek sustainable solutions to combat climate change and promote environmental responsibility, the utilization of wheat straw in conjunction with advanced materials like aerogel represents a compelling step forward in addressing the multifaceted challenges of our times.…”
