“…Accordingly, the structures with multiscale channels can be fabricated precisely. [2,70,159,186,193] The material extrusion methods exhibit plenty of advantages for the matrix manufacture, such as a broad range of suitable materials (carbon precursors, [154,194,195] ceramics, [196,197] and metals [198][199][200] ) and the intrinsic porous features resulting from the lyophilization [155] and pyrolysis. [198][199][200] The shear-thinning rheological properties of the inks are critical to print ideal architecture without collapse.…”

term solutions are urgently needed before adequate supply of the renewable energy. [1,2] Improvement of efficiency in the energy production and consumption processes is a key factor to address these problems. Meanwhile, the large reaction rate is a key factor to meet the industrial energy requirements. [1][2][3][4][5] Mass transport intensification is an effective method to improve the efficiency and reaction rate in the adsorptions, chemical reactions, and electrochemical reactions, which plays crucial roles in the gas (H 2 , CH 4 , CO 2 , etc.) storage, [6,7] energy conversion, [8] and energy storage. [3,9,10] Recently, novel batteries [2,3,[11][12][13] and microreactors [8,[14][15][16][17][18] for the gas (H 2 , CH 4 , CO 2 , etc.) storage [6,7] and energy conversion [8] have been developed to meet the requirements of high efficiency and rates. In these devices, the mass transport intensification is particularly important to acquire the high selectivity, large reaction rate, great conversion efficiency. [2,8,19,20] The mass transfer steps in the monolithic adsorbents, structured catalysts, and shaped electrodes are similar. Therefore, it is possible to use an identical term to describe the monolithic adsorbents, structured catalysts, and shaped electrodes for convenience to discuss the mass transfer processes. Herein, we use the hierarchically structured components (HSCs) to describe the structures which are comprised of designed channels and matrix between channels, where the matrix is made from functional materials (ceramics, carbon, metals, etc.) with pores in the size from nanometer to sub-millimeters, as illustrated in Figure 1a. In the flow batteries and fuel cells, the assembly of bipolar plate and electrode is regarded as HSC.Generally, the reactants undergo four steps (distribution, adsorption, acceleration, and reaction) in the HSC, as shown in Figure 1b-e. The distribution starts as soon as the reactant flows into the inlet. In this step, the reactant is distributed across the HSC through the designed channels, as shown in Figure 1b. [21,22] Subsequently the fluid is adsorbed by the macropores (>50 nm) which act as buffers for the reactants in the matrix, shown in Figure 1c. [23] As shown in Figure 1d,e, the reactants are accelerated by the mesopores (2-50 nm) and transferred to the micropores (<2 nm) which provide high surface area for the active sites. [23][24][25] After reaction at the active sites, the products are transferred by the mesopores and macropores to the outlet, successively. [26,27] Therefore, the Pursuing high energy efficiency and reaction rate is an effective direction in mitigating the energy and climate crisis. Mass transfer intensification is a powerful approach to enhance the energy efficiency and reaction rate in the energy conversion and storage processes. The nature-inspired channels are outstanding tools to uniformly distribute the reactants, fast remove products, and reduce the diffusion distance for mass transfer intensification in monolithic adsorbents, structured catal...

“…The sensor's response to NO 2 was remarkable at ppb levels. A new generation of sensors for greenhouse gases utilizing 3D printing and ink jet printing is to be expected in the future, and are being researched in the literature [114][115][116][117][118][119]. Although some of the analytes described in this section do not fall into the class of greenhouse gases, they provide the pathway for the development of new greenhouse gas sensors through ink jet printing.…”

With the increasing utilization of fossil fuels in today’s technological world, the atmosphere’s concentration of greenhouse gases is increasing and needs to be controlled. In order to achieve this goal, it is imperative to have sensors that can provide data on the greenhouse gases in the environment. The recent literature contains a few publications that detail the use of new methods and materials for sensing these gases. The first part of this review is focused on the possible effects of greenhouse gases in the atmosphere, and the second part surveys the developments of sensors for greenhouse gases with coverage on carbon nano-materials and composites directed towards sensing gases like CO2, CH4, and NOx. With carbon dioxide measurements, due consideration is given to the dissolved carbon dioxide gas in water (moisture). The density functional calculations project that Pd-doped single-walled carbon nanotubes are ideal for the development of NOx sensors. The current trend is to make sensors using 3D printing or inkjet printing in order to allow for the achievement of ppb levels of sensitivity that have not been realized before. This review is to elaborate on the need for the development of greenhouse gas sensors for climatic usage by using selected examples.

“…IJP is used for the deposition of submicronic particles (e.g., precious metal and ceramic materials) [59][60][61] in electronics [62], rapid prototyping [63], ceramic-based components [59,60] and sensors [64]. The viscosity range for ceramics-based inks for IJP is 1-20 mPa s and the deposited layer thickness is from below 100 nm up to 100 µm [65,66]. This, together with the low solid loading of the inks (1-10 vol%), makes IJP a time-consuming technique that is more suitable for low aspect ratios or 2D objects (opposite to other AM techniques that are more adequate for the fabrication of high-aspect ratio 3D parts) [67].…”

Solid Oxide Cell Electrode Nanocomposites Fabricated by Inkjet Printing Infiltration of Ceria Scaffolds

The enhancement of solid oxide cell (SOC) oxygen electrode performance through the generation of nanocomposite electrodes via infiltration using wet-chemistry processes has been widely studied in recent years. An efficient oxygen electrode consists of a porous backbone and an active catalyst, which should provide ionic conductivity, high catalytic activity and electronic conductivity. Inkjet printing is a versatile additive manufacturing technique, which can be used for reliable and homogeneous functionalization of SOC electrodes via infiltration for either small- or large-area devices. In this study, we implemented the utilization of an inkjet printer for the automatic functionalization of different gadolinium-doped ceria scaffolds, via infiltration with ethanol:water-based La1−xSrxCo1−yFeyO3−δ (LSCF) ink. Scaffolds based on commercial and mesoporous Gd-doped ceria (CGO) powders were used to demonstrate the versatility of inkjet printing as an infiltration technique. Using yttrium-stabilized zirconia (YSZ) commercial electrolytes, symmetrical LSCF/LSCF–CGO/YSZ/LSCF–CGO/LSCF cells were fabricated via infiltration and characterized by SEM-EDX, XRD and EIS. Microstructural analysis demonstrated the feasibility and reproducibility of the process. Electrochemical characterization lead to an ASR value of ≈1.2 Ω cm2 at 750 °C, in the case of nanosized rare earth-doped ceria scaffolds, with the electrode contributing ≈0.18 Ω cm2. These results demonstrate the feasibility of inkjet printing as an infiltration technique for SOC fabrication.
