“…The pressure drop across the filter (ΔP) (Pa) is determined by the difference between the upstream (Pup) and downstream (Pdown) pressures (Lu et al 2018;Ma et al 2018;Nie et al 2020a).…”

“…The air permeability can thus be adjusted by changing the basis weight, thickness, and/or density of the filter. For instance, as filter thickness decreases, air permeability increases (low pressure drop), although the filtration efficiency decreases (Nie et al 2020a).…”

“…There are many natural, synthetic, organic, and inorganic antimicrobial agents with an affinity for cellulose that can potentially be used in protective masks. These include natural bioactive compounds (e.g., polyphenols, terpenoids, organic acids, and polysaccharides), metalcontaining materials, inorganic salts (e.g., quaternary ammonium compounds (QACs)), synthetic polymers (e.g., N-halamines and polyhexamethylene biguanide (PHMB)) (Ristić et al 2011;Timofeeva and Kleshcheva 2011), and composites thereof, including MOFs, which are regarded as the most innovative today (Chua et al 2020;Nie et al 2020a). As highlighted in this section, several of them have antiviral properties, whereas other nanomaterials such as graphene can act as an enhancing agent for other well-known antiviral agents, e.g., silver nanoparticles (Ag NPs).…”

“…In addition to greater antimicrobial capacity, QAOM-coated paper exhibited higher tensile, shear, and bursting strengths than uncoated paper. For cellulose-based mask applications, chitosan has often been used in combination with other antiviral technologies to form nanocomposite materials, e.g., Ag NPs / chitosan (Imani et al 2011) and MOFs/chitosan (Nie et al 2020a), as presented throughout this section.…”

“…For instance, zeolitic imidazolate framework-8 (ZIF-8), copper(II)-benzene-1,3,5-tricarboxylate (Cu-BTC) MOF (MOF-199), and Ag-based MOFs (Ag-MOFs) are used for antibacterial applications (Ma et al 2018). A recent study investigated the potential of MOF-paper materials as antibacterial composites for air filtration (Nie et al 2020a). The authors used ZIF-8, a three-dimensional framework designed with zinc nitrate hexahydrate (Zn(NO3)2•6H2O) ions and 2-methylimidazole (2-H-MeIM, C4H6N2), combined with chitosan gel and mixed with softwood kraft pulp to produce ZIF-8/chitosan/cellulose composite paper filters.…”

Cellulose is among the most promising renewable and biodegradable materials that can help meet the challenge of replacing synthetic fibers currently used in disposable N95 respirators and medical face masks. Cellulose also offers key functionalities that can be valued in filtration applications using approaches such as nanofiltration, membrane technologies, and composite structures, either through the use of nanocellulose or the design of functional composite filters. This paper presents a review of the structures and compositions of N95 respirators and medical face masks, their properties, and regulatory standards. It also reviews the use of cellulose and nanocellulose materials for mask manufacturing, along with other (nano)materials and composites that can add antimicrobial functionality to the material. A discussion of the most recent technologies providing antimicrobial properties to protective masks (by the introduction of natural bioactive compounds, metal-containing materials, metal-organic frameworks, inorganic salts, synthetic polymers, and carbon-based 2D nanomaterials) is presented. This review demonstrates that cellulose can be a solution for producing biodegradable masks from local resources in response to the high demand due to the COVID-19 pandemic and for producing antimicrobial filters to provide greater protection to the wearer and the environment, reducing cross-contamination risks during use and handling, and environmental concerns regarding disposal after use.

Chronic wounds are characterized by delayed and dysregulated healing processes. As such, they have emerged as an increasingly significant threat. The associated morbidity and socioeconomic toll are clinically and financially challenging, necessitating novel approaches in the management of chronic wounds. Metal‐organic frameworks (MOFs) are an innovative type of porous coordination polymers, with low toxicity and high eco‐friendliness. Documented anti‐bacterial effects and pro‐angiogenic activity predestine these nanomaterials as promising systems for the treatment of chronic wounds. In this context, the therapeutic applicability and efficacy of MOFs remain to be elucidated. We, therefore, review structural‐functional properties of MOFs and their composite materials and discuss how their multifunctionality and customizability could be leveraged as a clinical therapy for chronic wounds.This article is protected by copyright.

Abstract2D MXenes family creates an interest in environmental cleaning and energy conversion. It shows large surface functional groups, electronic transmission, and electrical conductivity. This research focuses on Metal Organic Framework‐based Ti3C2 heterojunctions, directing on surface morphology control, customizable electrical structure, high performance in Ti3C2‐based electrocatalytic devices, and energy storage as a supercapacitor. In addition, future development obstacles and viable research possibilities are presented. MXene detailed analysis reveals a fundamental study, structure‐activity connections, and potential research paths for environmental applications. Specially developed MOF/MXene nanoarchitectures with remarkable features are highlighted in several study fields, including the chemical sciences, environmental engineering, physics, catalysis, and nanotechnology. They represent a new class of cutting‐edge developing materials. Mainly, the presented review describes multiple synthesis approaches by adjusting conditions for MOF/MXene nanoarchitectures with varying morphologies, and intriguing properties can also be developed for electrochemical energy conversion and storage.
