“…[ 13 ] As it is well known, the periodate oxidation reaction led to a specific cleavage of the C2—C3 bond in (MCC), resulting in the generation of active aldehyde groups in the polymeric chain.

[ 6,14,19,81 ] The obvious peak at about 1734 cm −1 proved that the aldehyde groups have been introduced into the (MCC) structure by periodate oxidation.…”

“…As mentioned in our recent works, [ 12,13,15 ] the FTIR spectrum of (MCC) (a) illustrated in Figure 3a exhibits characteristic peaks: C–O–C glycosidic ether bands at 1105 cm −1 , CH 2 rocking vibrations at 1315 cm −1 , OH stretching frequencies at 3200 cm −1 , and C–C ring breathing at 1053 cm −1.

Magnetic [FA‐c‐(C‐DTX)@Fe3O4] nanocomposites have been prepared with a four‐step technique involving three mechanical stirring conventional steps to obtain [(FA‐c‐(DTX‐g‐DAC)] and an ultrasound‐assisted Fe3O4 coating approach to fabricate [FA‐c‐(C‐DTX)@Fe3O4]. Magnetic nanoparticles (NPs) (Fe3O4 NPs) synthesis and integration has been easily and rapidly approached under novel environmentally friendly optimized reaction conditions: an ethanol–water solution, one iron precursor use, short reaction time, low temperature, and an ultrasonic irradiation process. This new condition's unique combination is attributed to our new synthesis procedure. Sonochemically synthetisized [FA‐c‐(C‐DTX)@Fe3O4] were easily separated from the reaction mixture simply via external magnetic field application, and therefore, neither filtration nor centrifigation was required. The synthetisized samples have been investigated by Fourier transform infrared (FTIR) spectroscopy, nuclear magnetic resonance (NMR) spectroscopy, X‐ray photoelectron spectroscopy (XPS), X‐ray diffraction (XRD), thermogravimetry analysis (TGA), scanning electron microscopy (SEM), and vibrating‐sample magnetometry (VSM). Obtained outcomes including successful magnetite coating process, good crystallinity, homogenous morphology, enhanced thermal stability, and obvious magnetic properties suggested the potential of sonochemical procedure to fabricate and integrate magnetic NPs. This sonochemically synthesized catalyst was evaluated toward the reduction of the organic pollutant 4‐nitrophenol and showed excellent catalytic activity. This ultrasound‐assisted nanocomposites preparation is simply scalable to meet industrial application.

Electromagnetic generators, thermoelectric generators, solar cells, piezoelectric nanogenerators (PENGs), and triboelectric nanogenerators (TENGs) are examples of energy-conversion devices based on different operating principles. [1,2] Triboelectric devices link contact electricity with electrostatic induction, transferring inductive charges across electrodes to convert mechanical energy to electricity. [3,4] Mobile devices, Internet of things (IoT), smart wearable gadgets, and devices globally use thousands of sensors. [5] Solid-state embedded power sources require milliwatts or microwatts, yet their compactness allows for frequent charging or battery replacement. [6,7] Selfrecharging devices combine an energy harvester with a battery. [8,9] TENGs are promising for energy efficiency. These gadgets can capture energy from natural sources, mechanical power, and faint heartbeats, proving their compatibility with severe environments and the human body. [10][11][12] Surface polarization and Maxwell's displacement current affect triboelectric devices. TENG's performance has improved from the January 2012 report. Triboelectric systems can yield 1200 W m À2 area power density, 490 kW m À3 volume density, and 50-85% conversion efficiency. [13][14][15][16] Triboelectric charge density on contact surfaces affects TENG voltage and current output in all four modes. Charge density quadruples output power. Polymers and metals are triboelectric microscopically. This leads to small improvements. Chemists and materials scientists are working on theoretical and practical TENG initiatives. [17][18][19][20][21] TENG output can be enhanced by optimizing friction pairings based on electron affinity and surface modification via physical or chemical techniques. Complementary micro-or nanostructure reinforcements, such as nanotubes, polymer matrices, nanofillers, or small molecules, can be added to the triboelectric layers to enhance their performance. A "small molecule" refers to any organic substance with a molecular weight of less than 1500 Dalton. The 1500 Dalton cutoff limit was established at 900-1000 Daltons in the literature. Small molecules can perform a wide range of tasks and have a wide variety of functions, including energy harvesting, cell signaling, sensor applications, and many more. [22,23] Recently, in the 2020s, researchers are trying to use small molecules to be harnessed into TENGs to increase their charge density, as small molecules revolutionize the field of solar energy harvesting. Apart from this, very few articles are found on improving triboelectric performance using small molecules and expanding TENG applications. It might be due to the inability to choose small molecules and increase the charge density of the triboelectric surface with insufficient rudimentary physics. [24][25][26][27][28][29] This review introduces small molecules and possible selection mechanisms (such as electron denoting and withdrawing groups, including dielectric constant engineering, higher crystallinity, pK a value, and tailoring di...
