Here, we demonstrate the tunable modification of CNC surfaces by physical adsorption of tannic acid (TA) and two alkyl cellulose derivatives (ACDs), methyl cellulose (MC) and ethyl cellulose (EC...

2023年2月14日 · The silane-modified CNC film was evaluated by FT-IR, XPS, and 29 Si-NMR, and glycidyl groups were qualitatively detected by FT-IR. The CNC/GPMDES/TEOS coating film had an enhanced hydrophilic...

Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) studies confirm the proper immobilization of XO onto nanocellulose surface.

2024年1月1日 · Bras et al. recorded the full XPS spectra for neat and improved CNC are revealed in Fig. 14.6F–I [55]. From the peak areas of the photoelectron, a quantitative XPS analysis can be done using Gaussian–Lorentzian deconvolution by determining the atomic concentrations.

2019年6月6日 · The exemplary XPS spectrum of the CNC@PDA nanoadsorbents, compared with that of pristine CNCs (Figure S2), provides further evidence of successful polymerization of dopamine. The new nitrogen peak at around 400.0 eV confirms the presence of PDA on the CNC@PDA nanoadsorbents (Fig. 2b).

2018年1月1日 · The APTES-grafted CNC was characterized by attenuated total reflection infrared spectroscopy (ATR-IR), energy dispersive X-ray analysis (EDX), X‐ray diffraction (XRD), solid-state 13 C and 29 Si nuclear magnetic resonance (NMR), X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TGA), and atomic force microscopy (AFM) and ...

2024年4月1日 · Sulfated cellulose nanocrystals’ (CNCs’) facile aqueous dispersibility enables producing films, fibers, and other materials using only water as a solvent but prevents using sulfated CNCs in applications that require water immersion.

2022年12月23日 · The efficiency of the modification with sawdust-derived CNC was investigated using zeta potential and X-ray photoelectron spectroscopy (XPS). The effect of the modification on membrane mechanical strength and stability in …

From the XPS full spectrum in Figure 3 a, it was confirmed that Ni, Co, O, and C elements were contained in the CNC hybrids. From the Ni 2p, Co 2p, O 1s, and C 1s high-resolution spectra, the...

In this work, we report the development of innovative hydrogels incorporating carbon dots (Cdots) for bioimaging purposes. Methods: The Cdots were prepared using a sustainable and low-cost process,...
