“…The binding energy (BE) peaks at ∼776, 778–783 and 779–785 eV were assigned to Co LMM Auger peak, Co 0 metal and Co 2+ of the Co 3 O 4 and/or CoO . The deconvolution of the C 1s core level spectrum for MOF-74 was carried out with six Gaussian curves (Figure e), which correspond to the sp 2 carbon bonding and satellite (sp 2 ), C C–C/C–H bonding, C–O bonding, CO bonding and COOH bonding . In the Cu 2p area (Figure f), two dominant peaks at 931.38 (Cu 2p 3/2 ) and 933.25 eV (Cu 2p 3/2 ) represent the formation of Cu 0 and/or Cu + (predominately in the +2-oxidation state).…”

The poor capacity retention of the silicon (Si) anode has hindered its widespread use in lithium-ion batteries. Metal− organic-frameworks (MOF) may offer the structural and functional tunability needed to alleviate some of the longstanding problems associated with silicon pulverization. Herein, MOF-74 (Co-based) and were implemented in different design configurations for high-Si loading electrodes. Multilayer sandwich configurations provided a modest improvement in capacity retention. However, greatest improvements in capacity retention were observed when the MOF was in situ synthesized onto the silicon surface (Si@ MOF) and subsequently pyrolyzed. The best performing high-loading 0.5Si@MOF-c sample delivered a high capacity of 1000 mAh/g and retained 60% capacity after 100 cycles, surpassing a standard silicongraphite composite.

“…The results of the XPS Si 2p spectra imply that when the SiC target is sputtered with the Ar/O 2 gas ambient, the Si atoms are deposited on CPI substrate in the form of SiO x C y . In addition, the XPS C 1s and O 1s spectra are also deconvoluted into subpeaks according to the chemical bonding states in Figure 2c,d [22][23][24]. The XPS C 1s spectra for Si-C, C-C, and C-O are deconvoluted into subpeaks that are located at 283.3, 284.5 and 286.2 eV, respectively.…”

We fabricated transparent and flexible silicon oxycarbide (SiOC) hard coating (HC) films on a colorless polyimide substrate to use as cover window films for flexible and foldable displays using a reactive roll-to-roll (R2R) sputtering system at room temperature. At a SiOC thickness of 100 nm, the R2R-sputtered SiOC film showed a high optical transmittance of 87.43% at a visible range of 400 to 800 nm. The R2R-sputtered SiOC films also demonstrated outstanding flexibility, which is a key requirement of foldable and flexible displays. There were no cracks or surface defects on the SiOC films, even after bending (static folding), folding (dynamic folding), twisting, and rolling tests. Furthermore, the R2R-sputtered SiOC film showed good scratch resistance in a pencil hardness test (550 g) and steel wool test under a load of 250 g. To test the impact protection ability, we compared the performance of thin-film heaters (TFHs) and oxide-semiconductor-based thin-film transistors (TFTs) with and without SiOC cover films. The similar performance of the TFHs and TFTs with the SiOC cover window films demonstrate that the R2R-sputtered SiOC films offer promising cover window films for the next generation of flexible or foldable displays.
