As a thriving member of the 2D nanomaterials family, MXenes, i.e., transition metal carbides, nitrides, and carbonitrides, exhibit outstanding electrochemical, electronic, optical, and mechanical properties. They have been exploited in many applications including energy storage, electronics, optoelectronics, biomedicine, sensors, and catalysis. Compared to other 2D materials, MXenes possess a unique set of properties such as high metallic conductivity, excellent dispersion quality, negative surface charge, and hydrophilicity, making them particularly suitable as inks for printing applications. Printing and pre/post-patterned coating methods represent a whole range of simple, economically efficient, versatile, and eco-friendly manufacturing techniques for devices based on MXenes. Moreover, printing can allow for complex 3D architectures and multifunctionality that are highly required in various applications. By means of printing and patterned coating, the performance and application range of MXenes can be dramatically increased through careful patterning in three dimensions; thus, printing/ coating is not only a device fabrication tool but also an enabling tool for new applications as well as for industrialization.devices. This is because solution processes such as liquid-phase exfoliation is crucial for the dispersion formation and mass production, as well as for the postsynthesis treatments on the 2D nanosheets such as sorting in terms of flake size and thickness, functionalization, compositing, etc., all of which are crucial for the ink formulation process required by printing. [6] Printed electronics technology has acquired considerable interest from both academia and industry recently. [7][8][9] Unlike traditional methods such as vacuum deposition and photolithography, printing technologies hold great promise for fast, high-volume, and low-cost manufacturing, especially for the fabrication of flexible devices. [10][11][12][13][14][15] The combination of 2D materials with printing started as early as 2012 when liquid-phase-exfoliated graphene dispersion was inkjet-printed to fabricate field-effect transistors. [16] It has since progressed from directly using the unoptimized dispersion obtained from the solution processing as inks to making formulated inks targeted toward specific printing methods and target applications (e.g., conductive tracks, transparent electrodes, transistors, photodetectors, energy storage devices such as supercapacitors, batteries, sensors, etc.).

[22][23][24][25] Research on MXenes dates back to 2011 when single-layered titanium carbide Ti 3 C 2 was synthesized and separated for the first time, [26] and has since evol...

In response to the request for sustainable high performance energy storage devices, a significant interest is focused on developing environmentally friendly supercapacitors. In this context, cellulose‐based substrates for energy storage devices can be well‐engineered, lightweight, safe, thin, and flexible. Herein, a scalable, low‐cost, and easy‐to‐process approach for the preparation of supercapacitors using large area techniques like spray and blade coating is presented. Following a green strategy, all components are chosen or formulated in water‐based dispersions. Symmetric supercapacitors using common copy paper and electronic paper as the substrate, and poly(3,4‐ethylenedioxythiophene)‐poly(styrenesulfonate) (PEDOT:PSS) as electrodes, are realized and investigated. The novelty of this work consists of the use of composites based on detonation nanodiamonds (DNDs) and hydroxypropyl cellulose (HPC) as a solid‐state electrolyte and separator. Devices with solution electrolyte using the same HPC + DND composite but with the addition of sodium sulfate are prepared. The performance obtained using solid electrolyte (HPC + DNDs) and liquid electrolyte (HPC + DNDs + Na2SO4) on both substrates is comparable in terms of specific capacitance: ≈0.13 – 0.52 F g−1 for (HPC + DNDs) and ≈0.35 – 0.82 F g−1 for (HPC + DNDs + Na2SO4), with power density in the range of ≈19 – 24 μW cm−2.

In summer, the high temperature inside vehicles is a problem, because cooling a vehicle parked under the scorching sun is both time and energy consuming. Herein, a portable solar‐powered cooling system (SPCS) is proposed based on a foldable‐flower mechanism and wireless power transfer (WPT) technology. The proposed system consists of three main parts: a solar foldable‐flower module (SFFM), an energy transfer module, and a temperature control module. The SFFM is a novel foldable mechanism that achieves a high space utilization through a rotating process and a folding process, like a flower opening its petals. The SFFM, equipped with photovoltaic (PV) cells, collects solar energy and converts it into electricity. The energy transfer module stores electricity from the SFFM in a supercapacitor via a WPT unit. The temperature control module achieves automatic temperature regulation using a cooling device. Experimental results show that output power reaches up to 7.571 W with a load resistor of 5 Ω, whereas the efficiency of the WPT reaches up to 73.6% with a load resistor of 15 Ω. Moreover, thermal simulation results illustrate that the proposed system achieves an average temperature reduction of 27.45 °C, making it feasible and effective to cool a hot vehicle cabin.
