“…Nanoengineered materials are advantageous due to their robustness, variety, and miniscule use in combating bacterial infections. Inorganic metal based antibacterial agents have attracted a lot of attention owing to their excellent antibacterial activity and unobnoxious nature toward healthy human cells. ,− Metallic antibacterial materials are mostly dominated by transition metals such as zinc and coinage metals such as gold, silver, and, copper . Silver has also established itself as an effective bactericidal agent, but it has two major drawbacks: first its exorbitant price and second the lack of a proper channel for its requisition. , …”

Bacterial infections being sporadic and uncontrollable demands an urgent paradigm shift in the development of novel antibacterial agents. This work involves the fabrication of Cu 2 O nanopetals over copper foil that show superlative antibacterial and superhydrophobic properties. A superhydrophobic surface has been fabricated using the electrochemical deposition (ECD) method. Here, it is aimed to establish the superior antibacterial activity as an outcome of the inherent superhydrophobic property of the as-fabricated nanostructures. The present study finds that the elevated value of the water contact angle (154 ± 0.6°) does not allow proper bacterial adhesion, and it is immune from the possibility of biofouling. Specifically, two kinds of bacterial strains have been tested and the time response of the antibacterial activity has been studied over a period of 12 h, taking DH5α Escherichia coli as a Gram-negative model and Bacillus subtilis 168 as a Gram-positive model. Higher antibacterial effects were observed for the Gram-negative model (E. coli) owing to its simplistic cell wall structure which facilitates the easy diffusion of Cu + ions into the bacterial membrane. The simplicity of the developed method of fabrication along with the superlative superhydrophobic nature and excellent antibacterial property of the material, owing to its synergistic biophysical and biochemical modes of biocidal action, establishes its viability in many applications.

“…No impurity peak was observed in the XRD pattern, indicating that H/ZSM‐5 was very pure. The diffraction peaks of Cu/ZSM‐5 catalysts were similar to that of H/ZSM‐5, in that no characteristic diffraction peaks of Cu, Cu 2 O or CuO crystal phases were observed . That might be because of the weak crystallization or very small CuOx ( X = 0, 0.5, 1) cluster sizes, implying that the CuOx species were well dispersed on the Cu/ZSM‐5 prepared with different precursors .…”

BACKGROUND The combined Adsorption‐Nonthermal Plasma Catalytic process (A‐NTP‐C) which is used for decomposition of NOx has become a technical approach of high research value.Many studies have shown that the better the adsorption performance of the catalyst in the A‐NTP‐C process, the higher the conversion of NO. The type of Cu precursors will affect the chemical/physical properties of Cu‐based catalysts, thus influencing the adsorption performance of catalysts. In this study, an ion exchange process was used to prepare Cu/ZSM‐5 catalysts with three Cu precursors, namely copper acetate (AC‐Cu), copper nitrate (N‐Cu) and copper sulfate (S‐Cu). Results Different Cu precursors led to differences in Cu ion exchange capacity of Cu/ZSM‐5; the Cu content of AC‐Cu/ZSM‐5 was the highest. Furthermore, even with the same Cu content as N‐Cu/ZSM‐5 and S‐Cu/ZSM‐5, the AC‐Cu/ZSM‐5 catalyst showed the best adsorption performance. Conclusion X‐ray photoelectron spectroscopy results indicated that CuO and isolated tetrahedron‐coordinating Cu(II) were the main forms of Cu species on Cu/ZSM‐5. The results of in situ DRIFTs indicated that NO was oxidized by CuO and the generated NO2 was adsorbed by H+ and isolated Cu (II). The AC‐Cu/ZSM‐5 catalysts had the largest amount of tetrahedron‐coordinating isolated Cu (II) and the strongest H+ electrophilic ability, giving it the best NOx adsorption performance. The different precursors had little effect on the ZSM‐5 structure, but did cause differences in pore volume, which might influence the adsorption capacity of NOx to some extent. These conclusions provide new ideas and methods for optimizing the adsorption capacity of Cu/ZSM‐5. © 2019 Society of Chemical Industry © 2019 Society of Chemical Industry

In this review work, we highlight the origin of morphological structures such as nanofibers/nanorods in case of various materials in nano as well as bulk form. In addition, a discussion on different cations of different ionic radii and other intrinsic factors is provided. The materials (ceramic titanates, ferrites, hexaferrites, oxides, organic/inorganic composites, etc.,) exhibiting the nanofibers/nanorods like morphological structures are tabulated. Furthermore, the significance of nanofibers/nanorods obtained from distinct materials is elucidated in multiple scientific and technological fields. At the end, the device applications of these morphological species are also described in the current technology.
