“…Its derivative MCC is a microsized and tasteless naturally available substance found from purifed and partially depolymerized cellulose. Due to its exceptional properties such as biodegradability, chemical inactivity, high surface area for bonding with resins, high sorption, absence of toxicity, and great hygroscopicity, MCC has gained attention for various applications such as cosmetics, pharmaceutical, bio composite reinforcement, and beverage [24,25]. Te extraction techniques for MCC particles are several including mechanical treatment, biological treatment, and chemical treatment.…”

Coffee husk (CH) is a sustainable and abundantly available cellulosic waste material. Its fiber consists of cellulose as the major structural part which leads to potential utilization for the manufacturing of microcrystalline cellulose (MCC) products that can be utilized for different industrial applications. In the present study, chemical composition of outer skin-isolated coffee husk was determined and sequential treatments of various untreated (UT) sample, ethanol—toluene treated sample through dewaxed (DW) treatment, sodium hydroxide (NaOH)—treated sample through alkali (AT) treatment, and sulfuric acid (H2SO4)—treated sample through bleaching (BL) treatment have been carried out. The Micro Crystalline Cellulose (MCC) has been extracted through hydrogen peroxide (H2O2) after BL treatment. The BL treatment for MCC extraction process was conducted without chlorine and additional harsh acid treatment, respectively. The characterization of chemically treated samples was carried out to investigate their morphological, physico-chemistry, and thermal behavior through a scanning electron microscope (SEM), Fourier transform infrared—ray (FTIR), X-ray diffraction (XRD), thermo gravimetric analysis (TGA), and differential temperature analyzer (DTA). From the chemical composition analysis; the cellulose, hemicellulose, lignin, and extractive content were determined and its values were (52.9%), (12.5%), (24.3%), and (9.4%), respectively. In the morphological examination, the great untreated (UT) fiber sample was greatly reduced into a micro-sized BL sample, revealing that (from FTIR analysis) the lignin and hemicellulose contents were greatly removed during chemical treatments and the presence of a micro crystalline cellulose region with 54.7% yield. Also, the sample AT and BL showed the lowest amorphous region in X-RD due to the removal of hemicellulose and lignin. The highest crystallinity index has been determined for the BL sample, i.e., 89.9%. Additionally, the thermal analysis shows that the AT and BL sample has great thermal stability than other (UT and DW) samples at high temperature. Therefore, the outer skin separated coffee husk was prepared from agricultural waste was subjected to eco-friendly chemical treatments to yield MCC. Thus, the extracted MCC is expected to be reliable for replacing other plant materials for the production of crystalline nanomaterial and reinforcing constituent for the fabrication of bio composite.

“…Основними передумовами для використання наноцелюлози в сенсориці є її доступність, біорозкладність, стабільність поверхні, гнучкість, високий модуль Юнга та міцність на розрив. Нині наноцелюлоза та її композити були використані в різноманітних сенсорних пристроях: датчиках фізичних параметрів навколишнього середовища (температури [9], вологості [10], концентрації важких токсичних металів у стічних водах [11], газових забруднювачів навколишнього повітря [12]), біосенсорах рідин, зокрема фізіологічних рідин та харчових продуктів (для виявлення глюкози [12], гуаніну та аденіну [12], нейтрофілів еластази, диклофенаку натрію [13], іонів металів [12], біомаркерів, свіжості їжі тощо) та у зручній для людини інтерактивній сенсорній електроніці, включаючи електронні шкірні пристрої (датчики деформації та вібрації) [14,15]. Однак для різних видів сенсорів є свої вимоги, яким має задовольняти наноцелюлоза, та свої експлуатаційні обмеження.…”

Problems. Rapid technical progress has led to a reduction in the useful life of consumer electronics. The introduction of green, flexible, biodegradable electronic devices will prevent an environmental catastrophe. Recently, the use of organic materials instead of inorganic analogues has become increasingly popular, which makes it possible to move from rigid solid-state sensors for multiple use that require disposal to flexible, disposable sensors that are suitable for human wear on the body or clothing and for spontaneous decomposition in nature after using. One of such promising organic materials is nanocellulose. The aim of the study. Studying the possibility of nanocellulose application for the manufacture of flexible, wearable, disposable sensors of various types of physical and chemical quantities. Methodology of implementation. In the article the analysis, classification and comparision of various technologies and features of synthesis, as well as the main characteristics of flexible sensors made on the basis of nanocellulose were fulfilled. Also the main parameters of flexible sensors based on nanocellulose were being compared with corresponding analogs of sensors based on artificial polymers. Research results. The paper established the physical and technological features of using nanocellulose for the manufacture of sensors of various types of physical and chemical quantities in order to improve their performance. It has been established that nanocellulose can be used both as a substrate and as a sensitive element of a sensor. It has also been shown that nanocellulose is suitable for use in sensors based on both electrical physical phenomena and optical effects. Conclusions. Nanocellulose is a promising biodegradable material on the basis of which flexible, disposable, wearable sensors can be created. The manufacturing technology of such sensors should contain only low-temperature and dry processing processes. For effective use in certain types of sensors, it is advisable to manufacture nanocellulose with a modified surface or in the form of composites with other nanomaterials. Based on the obtained results, it is possible to improve existing and develop new methods of creating flexible wearable disposable sensors that do not require disposal.

Particulate matter (PM), usually formed as aerosols suspended in atmosphere, is becoming a carrier of viruses and bacteria, accelerating the spread of respiratory diseases. Hence, air filtration devices are widely utilized for removing PM. In this study, a regenerated cellulose (RC) film was prepared with the properties of good mechanical strength, antibacterial, and highly efficient filtration (EF) properties, through cellulose dissolution and further crosslinking with P(AGE-DMDAAC)/ZnO. Results exhibited that the Young’s modulus of the composite membrane was nearly 4.3 GPa. Additionally, the antibacterial performance against Escherichia coli and Staphylococcus aureus, was up to 99.89% and 99.67%, respectively. Meanwhile, RC composite filter exhibited a high PM 2.5 capture efficiency (over 99.91%). This study introduces an interesting approach to produce antibacterial films with the characteristics of notably good mechanical performance and high fine particle EF that can be utilized in a high humidity environment.
