Recent development for cellulose inks have provided methods to deal with important volume shrinkage resulting from the drying and evaporation of the dispersing solvent. [14] In order to make a reliable 3D printable ink, the relevance of understanding parameters such as the rheological properties (controlling the printability) [15] and the conductivity was evidenced by previous research. [16] Rheological aspects involve a shear-thinning behavior and the existence of a yield stress to enable a proper extrusion and shape fidelity of prior and after 3D printing. [17] The conductivity of the ink can be controlled by the addition of conductive fillers such as silver flakes, silver nanowires (AgNWs) as earlier research suggested. [18,19] Among other electrochemical sensor platforms, ion selective membrane sensors have been reported as efficient tools to detect ion analytes selectively from ion mixed solutions such as pH, [20][21][22][23] glucose, [24] or urea. [25] Furthermore, by integrating with Field Effect Transistors (FETs), the analyte information is quantitatively analyzed using Ion Selective Field Effect Transistors (ISFETs). [26][27][28] Recyclable ISFETs based on oxide semiconductors were also studied for sustainability. [29] High selectivity and stability enable ISFETs to be investigated for potential applications in biomedical and environmental fields. ISFETs are mainly controlled by the generated potential from ion selective electrodes and the generated potential influences the electrical performance of FETs. Therefore, variation of ion concentration is reflected by the fluctuation of drain current, drain voltage, or output voltage. Specially, wireless ion selective sensors are demonstrated to extract remotely ion concentration signals out of analyte solution. Consequently, a great interest was demonstrated over the past years in the fields of real-time monitoring and internet-of-things (IoT) applications. Research was conducted in integrating novel wireless technologies, such as RFID, [30][31][32][33][34] Bluetooth, [35,36] Zigbee, [37] or NFC [38] together with electrochemical sensors for wireless analytes information recovery. A conventional approach for wireless sensing with silicon-based chip technology has been already developed. [31] As the wireless communication technologies are becoming more crucial for internet-of-things (IoT) electronic devices, sensors have also been equipped with wireless data collection. A conventional way to make wireless sensor systems is to develop active sensor devices with silicon-based chip technologies integrated with an amplifier, a battery, a converter, among others. However, it is difficult to generate disposable inexpensive flexible sensors with all these rigid components. Here, 3D printed disposable wireless ion selective sensor systems with unique form factors, high sensitivity, and flexibility are reported. A 3D printable conductive ink is designed and optimized with cellulose nanofibers by addition of silver nanowires for sustainable and biocompatible sensor app...

The authors review selected topics in the development of hydrogenated amorphous silicon (a‐Si:H), from its emergence some 50 years ago to its present status as a mature thin‐film semiconductor, with market successes including flat‐panel displays, solar modules, and x‐ray scanners. By altering process gas mixtures and deposition conditions, films with a range of atomic, structural, and amorphous/crystalline phase compositions may be deposited, offering tunable bandgap, refractive index, and light‐scattering properties. Films thus “functionalized” have greatly increased scope and utility. Three emerging applications are reported, and more extensive sections on two topics of current importance are presented: 1) Multi‐junction thin film silicon solar cells for water splitting applications; and 2) thin‐film silicon solar cells on flexible substrates.

“…Application of the papers vary depending on the nature of the material, strength, chemical properties, pore size, void volume space, thickness, flow rate, durability etc [1,2]. The most common applications of the paper are value representative (money, ticket etc), information storage (newspapers, books etc), writing, printing, packaging, cleaning, laboratory filtration etc [4]. The physical and chemical modification of the existing papers can result into other advanced applications like electronic, piezoelectric and energy devices, microfluidic based biosensors, chemical and physical sensors, heavy metal ion filtration and bio-diagnostic devices, and antibacterial materials etc [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16].…”

Zinc oxide nanoparticles (ZnO-NPs) were synthesized and decorated simultaneously onto the glass fiber pre-filter paper (GF paper) by the sonochemical method without using any additional reagents (a 'Green' synthesis approach). ZnO-NPs decorated GF paper was characterized by electron, confocal laser scanning and atomic force microscopy, fourier transform infrared and atomic emission spectroscopy, X-ray diffraction, and thermogravimetric analysis etc. Due to the massive void volume space, exceptional dimensional stability, large thickness (790 μm) of the GF paper (unlike other paper materials) and ultrasonic irradiation effects, ZnO-NPs were decorated in the enormous amount (96 mg per paper) without causing any adverse effects on the GF paper. Such a huge amount decoration onto GF paper makes it multifunctional, fluorescencet (orange-pink color, 535-624 nm) under ultra-violet light (360 nm) and antibacterial. The antibacterial activity of the ZnO-NPs decorated GF paper was examined against Gram-positive bacteria Bacillus subtilis 168 and Staphylococcus aureus (MCC 2043, pathogenic). The outcomes from the antibacterial experiments revealed ∼99% (2 log) reduction in the survival of the filtered bacteria (B. subtilis) on the ZnO-NPs decorated GF paper due to the toxicity of ZnO-NPs on bacterial cells like cell shrinkage, cytoplasmic leakage, cell burst, etc. Multifunctional, ZnO-NPs decorated GF paper could be used for fluorescencet and antibacterial paper-based applications.techniques are its expensiveness, inefficient in throughout three dimensional (3D) coating, requirement of extra reagents etc [15]. Thus, appropriate paper material as well as coating technique is required to fabricate costeffective and novel multifunctional paper. To the best of our information, fewer reports are available on glass filter papers. Through this study we have tried to explore the properties and possible applications of existing glass fiber pre-filter paper (GF paper) through decoration with the zinc oxide nanoparticles (ZnO-NPs). GF paper is made up of borosilicate microfibers, silica (SiO 2 ) as a main component and some quantity of boron oxide (B 2 O 3 ), aluminium oxide (Al 2 O 3 ), sodium oxide (Na 2 O) and potassium oxide (K 2 O) [17]. Glass fibers have some exceptional properties which make them very different from natural fibers such as excellent strength, heat and chemical resistant but not to strongly alkaline and acidic (hydrofluoric acid) environment [17]. Fibers of the GF paper are thinner in diameter (100 nm to several μm) and uniform in contrast to the fibers of the other papers because of which GF paper have massive void volume space and large surface area [17]. Thickness of the GF paper is large (790 μm), so all these properties make it appropriate for filtering heavily contaminated liquids. Resin bonded and unbounded GF papers are available for the wide application in the filtration technique. Acrylic resin-bonded GF papers have more rigidity, dimensional stability and strength in comparison to the unbounded one as ...
