“…Essential oils derived from natural sources are generally considered bioactive and biocompatible [175]. When integrated into nanofiber materials, they are less likely to cause adverse reactions or toxicity, making them suitable for biomedical applications like tissue engineering, drug delivery, and wound healing [176][177][178]. Wang et al [179] selected clary sage and black pepper essential oils to prepare PLA nanofiber, and studies have shown that these essential oils impart antibacterial, anti-inflammatory, or anti-oxidant properties on electrospun fibres.…”

A flexible and dependable method that has been extensively employed to construct nanofibrous scaffolds that resemble the extracellular matrix made from polymeric materials is electrospinning (ES). ES is superior to other techniques because of its unique capacity to create nanofibers with a high surface-to-volume ratio, low cost, simplicity of setup, freedom in material choice, and ability to alter the surface attributes and usefulness of the nanofibers. However, the low productivity of nanofibrous membrane from conventional ES with the generation of tightly packed nanofibrous sheet-like two-dimensional membranes impedes cellular infiltration into scaffolds during tissue regeneration. Moreover, toxic organic solvents are desired for polymer dissolution for ES. Such solvents produce volatile organic compounds (VOCs) during electrospinning, which can degrade the indoor air quality of working place. Furthermore, when electrospun membranes containing traces of such VOCs are employed as tissue scaffolds, it may cause serious effect to cells and tissue. This justifies the need for alternative green solvents which are not only environmentally friendly, non-toxic, and low-cost but also biocompatible with medicinal values. Therefore, this review mainly focuses on summarizing the recent advances in ES machines, fabrication of three-dimensional (3D) spongy nanofibrous membrane, and introducing green solvent for polymer processing. Finally, based on the findings of the existing literature and our experience, this review mainly focuses on essential oils as future “greener” alternatives to current toxic solvents used in ES process.

“…As a membrane for seawater desalination, environmentally friendly alcohol-based polyamide mats were realized via one-step green solvent/non-solvent electrospinning by directly incorporating the fluorinated chemical into spinning solutions. The resultant polyamide nanofiber membranes exhibited high vapor permeation, good tensile strength, and elongation, thus permitting robust seawater desalination performance with remarkable salt rejection (99.97%) [ 96 ].…”

In the last two decades, several processes have been explored for the development of micro and/or nanostructured substrates by sagely physically and/or chemically manipulating polymer materials. These processes have to be designed to overcome some of the limitations of the traditional ones in terms of feasibility, reproducibility, and sustainability. Herein, the primary aim of this work is to focus on the enormous potential of using a high voltage electric field to manipulate polymers from synthetic and/or natural sources for the fabrication of different devices based on elementary units, i.e., fibers or particles, with different characteristic sizes—from micro to nanoscale. Firstly, basic principles and working mechanisms will be introduced in order to correlate the effect of selected process parameters (i.e., an applied voltage) on the dimensional features of the structures. Secondly, a comprehensive overview of the recent trends and potential uses of these processes will be proposed for different biomedical and bio-sustainable application areas.

“…Fresh water shortage represents one of the foremost challenges facing the world . Among the varied technologies developed to overcome this challenge, − sorption-based atmospheric water harvesting (AWH), water extraction from the ambient air with sorbents, has attracted particular interest due to its advantageous features in energy efficiency, relatively less climate dependence, and a wide range of geographic applicability. − To date, a great number of sorbents such as hygroscopic salts, polymer aerogels, active carbons, and metal–organic frameworks (MOFs) have been widely explored for AWH. − Of them, MOFs have been identified as an important type of AWH sorbents particularly suitable for AWH in arid areas due to their outstanding atmospheric water adsorption at low relative humidity (RH), low energy input for regeneration, and well tailorable surface and porosities for adaptive AWH. − MOF-based AWH follows a temperature-swing adsorption (TSA) principle: atmospheric water adsorption at ambient temperature and water desorption at elevated temperature with external heating sources. Effective MOF heating, therefore, plays a critical role in determining the water productivity and energy cost of MOF-based AWH. − …”

All-day atmospheric water harvesting (AWH) using metal–organic frameworks (MOFs) presents an appealing approach for achieving high-yield water production in arid regions. However, current all-day MOF-based AWH strategies often involve intricate material preparation procedures and high energy input for water desorption, raising concerns about the water production cost. Leveraging the naturally abundant solar energy available in arid areas, herein, sprayable Ti3C2 MXene/silane-decorated hyperbranched polymer solutions (Ti3C2/sHBP) are presented. These solutions enable easy formation of robust, spray-applied coatings on monolithic MOFs upon exposure to sunlight, resulting in monolithic Ti3C2/sHBP-coated MOFs (TCM). The presence of Ti3C2/sHBP coatings equips TCMs with dual solar and electrical heating capabilities, enabling adaptive all-day AWH based on sunlight availability: solar heating-driven AWH when sufficient sunlight is present, combined solar/electrical heating-driven AWH when sunlight is insufficient, and electrical heating-driven AWH during periods without sunlight. Compared to traditional electrical heating-driven AWH, this adaptive all-day AWH delivers a similar water production performance with a 28.8% reduction in energy consumption for water desorption. Imparting MOF monoliths with dual heating functionality through a straightforward spray-applied coating demonstrates a novel, facile, and cost-effective strategy for enabling adaptive all-day AWH with excellent water productivity at a significantly mitigated energy cost.
