“…Another component of this group is levoglucosan, a main product from cellulose pyrolysis [57] ; its yielding decreases at temperatures higher than 530 °C, which in turn generates decomposition compounds of lower molecular mass. In all the cases under study, levoglucosan content in the aqueous fraction was less than 1.1 wt% Levoglucosan is commonly used as a chemical tracer of biomass burning in atmospheric studies [58,59] and hydrolysis of levoglucosan produces glucose [60,61] , a significant monomer used in the biorefinery sector. Aldehydes and heterocycles content was higher in the aqueous fraction from RH.…”

<p>Pyrolysis and gasification are thermal treatment processes using biomass to produce biofuels that can replace fossil fuels in industrial boilers and furnaces. This paper discusses the potential utilization of four types of residual biomass highly produced in the Argentina Northeast (NEA) region, i.e., rice husk, an agricultural waste rich in cotton husk, carob sawdust, and spent red quebracho sawdust, as raw material. Pyrolysis liquid product yields were 34–51 wt% and char yields were 29–40 wt%; tar represented 16–23 wt%. For gasification, gas yields were between 45.6 wt% and 65.7 wt%; as for tar, it represented 2.4–14.1 wt% of initial biomass, and char yields were 31.4–40.3 wt%. Characterization of all products was performed to clarify their potential applications. Bio-oils, i.e., aqueous fractions of pyrolysis liquid products, have high water content (77–88 wt%), that is why they have lower density and viscosity than tars, oil fractions of pyrolysis liquids. However, chemical stability of bio-oils may vary, and their heating values are much lower than the heating values from tars. Based on these, it is possible to concluded that tar is the product with increased added value and higher energy properties. Efficiency of gasification and heating values of the gases obtained were high for waste rich in cotton husk and spent red quebracho sawdust, suggesting a good potential for the utilization in gasification processes. Additionally, char composition and properties for all biomasses, from both process, show that it is feasible to use them in several new applications.<strong></strong></p>

“…The linear detection range is 0-64.8 μg m/L and the detection limit is 2 and 6 μg m/L. The device showed selectivity for levoglucosan with variation in colorimetric signal intensity lower than 8% (Dias et al, 2019). Seok et al developed a μPAD combined with a 3D printed analysis kit for detection of airborne bacteria by collecting aerosols (Seok et al, 2021) (Figure 6C).…”

Effective environmental monitoring has become a worldwide concern, requiring the development of novel tools to deal with pollution risks and manage natural resources. However, a majority of current assessment methods are still costly and labor-intensive. Thanks to the rapid advancements in microfluidic technology over the past few decades, great efforts have been made to develop miniaturized tools for rapid and efficient environmental monitoring. Compared to traditional large-scale devices, microfluidic approaches provide several advantages such as low sample and energy consumption, shortened analysis time and adaptabilities to onsite applications. More importantly, it provides a low-cost solution for onsite environmental assessment leveraging the ubiquitous materials such as paper and plastics, and cost-effective fabrication methods such as inkjet printing and drawing. At present, devices that are disposable, reproducible, and capable of mass production have been developed and manufactured for a wide spectrum of applications related to environmental monitoring. This review summarizes the recent advances of low-cost microfluidics in the field of environmental monitoring. Initially, common low-cost materials and fabrication technologies are introduced, providing a perspective on the currently available low-cost microfluidic manufacturing techniques. The latest applications towards effective environmental monitoring and assessment in water quality, air quality, soil nutrients, microorganisms, and other applications are then reviewed. Finally, current challenges on materials and fabrication technologies and research opportunities are discussed to inspire future innovations.

“…A composição química do MP depende de sua fonte de origem e do tipo de atividade exercida no local (DIAS et al, 2019;MASELLI et al, 2020;CERATTI et al, 2021). Portanto, é bastante variável, podendo ter em sua constituição metais, compostos orgânicos, inorgânicos e microrganismos (FRANCO, 2016).…”
