“…A broad OH vibration peak is observed at 3436 cm −1 which is similar to that of in Ref. [19], displaying that absorption bands in the range between 3373-3546 cm −1 are associated to the symmetrical stretching of hydroxyl groups (OH). Other transmittance peaks in the FTIR spectrum are observed at 1157 cm −1 (CO stretching vibrations), at 1689 cm −1 (CO stretching vibrations) and at 1582 cm −1 (CC stretching vibrations).…”

We have processed biomass from palmyra sugar to produce allotrope carbon by heating process with the variation of calcination temperature. The formation of amorphous carbon (a-C) was confirmed from the XRD result heated at 400 • C with the observation of the peak at the position of 24 • . By increasing the temperature at 700 • C, the presence of two peaks at 24 • and 43 • were observed, indicating the formation of rGO-like phase. The functional groups detected by FTIR spectra consist of C=C, C-O, C=O, C-H and O-H. The conductivity measurement confirmed that the conductivity for a-C and rGO samples at room temperature are 4.50 S/m and 6.53 S/m, respectively. The result of conductivity measurement exhibits that the material can be classified as semiconducting materials.

“…This phenomenon is not affected by temperature variation because the little carbon deposited undergoes incomplete hybridization and thus contributes to a disordered carbon matrix. The carbon materials consist of a mixture of sp 2 and sp 3 hybrid carbons that do not completely close the graphite rings of the carbon material and hence amorphous carbon products [39]. At high flow rates and short time periods, amorphous carbon rapidly deposits on the catalyst material, and the carbon is inadequately crafted into disordered products.…”

Deposition-precipitation using urea (DPU) method was efficiently used to load lanthanum and nickel catalyst nanoparticles onto the radially aligned nano rutile (RANR) support material to achieve a metal loading ranging from 1 to 10 wt. % La-Ni/RANR co-loaded supported catalysts. The PXRD peaks due to La occurred at 2θ values <30° and increased in intensities with an increase in La wt. % loading. The occurrence and distribution of the catalyst metal phases were analyzed using wavelength dispersive spectroscopy mapping (WDS) of the electrode probe microanalysis technique (EPMA). The reduction profiles showed TPR peaks that shifted to higher temperatures with an increase in metal wt. % loading. TEM micrographs of the La-Ni/RANR-supported catalysts showed that at different wt. % loadings, the particles deposited take different shapes and sizes with polydisperse La-Ni nanoparticles assuming a short rod-like structure at 1% wt loading. The La-Ni/RANR catalyst directly affected and influenced the nature of the carbon nanomaterials in CVD reactions under different parametric conditions of varied wt. % composition, temperature, flow rate, and time. It was concluded that the straight CNFs were catalyzed by the La end, while the coiled or twisted CNFs were catalyzed by the Ni end of this catalyst.

In comparison with the implantable electronics, ingestible electronics are less invasive but can travel close to major organs through the gastrointestinal (GI) tract, monitor a wide range of biomarkers and therapeutic targets, and serve as effective clinical tools for diagnostics and therapy. [4d,5] Today, GI conditions have become one of the most prevalent health concerns in modern society. The market was expected to nearly reach the one-billion-dollar mark. [4e] Through analyzing the conditions of the GI tract [4d] (Figure 1), many diseases can be monitored and diagnosed, e.g., refluxing gastric fluid, cancer, motility disorders, infected and abnormally dilated venous vessels, gastritis, gastric ulcers, coeliac disease, lactose intolerance, Crohn's disease, inflammatory bowel disease, diverticular disease, constipation, clostridium difficile-associated diarrhea, irritable bowel syndrome, etc. [5,6] Conventional ingestible electronics mostly consist of inorganic materials and encapsulated with rigid nondegradable polymer, such as polydimethylsiloxane, parylene/epoxy, [4a] which will lead longer devices retention in the GI tract. This is one of the most significant risk elements during the application of conventional ingestible electronics. Fully food-based edible and nutritive electronics have emerged to address these potential risks. Edible electronics are new generation ingestible electronics. Recently, there is no accurate and clear definition of edible electronics. [4g,7] The definition of "transient electronics," [3h] which focused on implantable electronics, was similar to the edible electronics concept and defined as: made of biodegradable materials and can completely or partially dissolve, resorb, or physically disappear after functioning in environmental or physiological conditions at controlled rates. By follow this spirit, the definition of edible electronics is provided here: a class of microencapsulated electronic devices that consist of edible and nutritive inorganics and organics materials, meanwhile, that can be mainly dissolved, digested and absorbed after fulfilling the diagnosis or therapy of diseases in the gastrointestinal tract. The edible and nutritive inorganics always include edible inert metals, trace elements [8] and their oxides. Nutritive organics always include biopigments, and polymers. [7,9] A more systemic and expanded materials toolbox will be very helpful to advance The emerging novel edible and nutritive electronics indicate an important advance in ingestible and implantable electronics, covering multiple disciplines such as biomedicine, electronics, and nutriology. This review focuses on the feasibility and critical technical problems of fabricating fully edible and nutritive electronics. Recently, a limited number of fully edible and nutritive electronics, operating single functions, have been applied to monitor the condition of the gastrointestinal (GI) tract and diagnose its disorders. However, fully edible, nutritive, miniaturized, and well-functioning electronics with mu...
