“…Methods such as electrochemical deposition [27,28] and sol-gel methods [29,30] can simplify the processing; yet they require hazardous or expensive solutions, respectively. Thermal oxidation methods [31,32] can provide a simple bottom-up approach of forming copper oxide nanostructures on a copper substrate. However, they require vacuum conditions and still cannot easily generate film-free nanostructures directly on the Cu (e.g.…”

ABSTRACT:In this research, special wettable copper mesh owing superhydrophobicity and superoleophilicity property is reported using a low-cost, eco-friendly, rapid, and scalable synthesis methods. Hot water treatment (HWT) method is used to integrate the micro-textured copper mesh surface with a nanoscale roughness to achieve hierarchical micro-nano structured surface. The surface energy of the nanoscale In addition, the effect of the mesh's geometry on the wetting property was examined through correlations between wire diameter, pore size, and optimal values for the highest water CA.

“…4Cu + O2 → 2Cu2O (12) 2Cu2O + O2 → 4CuO (13) Thermal oxidation of copper, is an attractive technique due to its simplicity, highquality and low-cost, nevertheless it is a time consuming route [374]. Besides thermal oxidation, several other techniques have been used to produce copper oxides, including hydrothermal synthesis [367,375], microwave irradiation [376] and microwave oxidation [11], sol-gel method [377,378], spray pyrolysis [25,379], electrodeposition [380,381], sputtering [382,383], among others.…”

Human health, environmental protection and safety are just a few examples of current humankind main concerns, that drive the scientific community to develop sensors able to precisely monitor and alert to possible harms in real time. Over the years, semiconductor metal oxide-based materials have been largely employed as sensors dedicated to several applications, being particularly interesting at the nanometer scale, since it is largely known that smaller crystallite size enhances sensor's performance. Moreover, these materials are highly appealing as they can be produced by low-cost wet-chemical synthesis routes and are in general nontoxic, earth abundant and low-cost. This manuscript extensively reviews the recent developments of nanostructured semiconductor metal oxide sensors ranging from gas to humidity sensors, including ultraviolet (UV) sensors and biosensors. Zinc oxide (ZnO), titanium dioxide (TiO2), tungsten trioxide (WO3), copper oxide (CuO and Cu2O), tin oxide (SnO and SnO2), and vanadium oxide (VO2, V2O5)-based sensors either as nanoparticles or as continuous films/layers are described. Their sensing properties are correlated to size, shape, presence of defects, doping elements, amongst other relevant parameters. Different techniques and methods of fabricating these materials are addressed. The review is concluded with novel approaches for functionalization and future perspectives for sensor developments.

The template synthesis of ethylenediamine (1) with 2‐acetylcyclopentanone (2) and [Cu(OAc)2·H2O] (5) produced [Cu(1‐(2‐cC5H6(O))C(Me)NCH2)2)] (6) in 82 % yield. Reaction of 5 with bis(benzoylacetone)diethylenetriamine (7, = LH)[1] gave [Cu(μ‐OAc)(L)(H2O)]2 (8). The solid‐state structures of 6 and 8 were determined confirming that 8 possesses intra‐ and intermolecular hydrogen bonds resulting in a dimer formation. The thermal behavior of 6–8 was studied by TG and TG‐MS. Under oxygen CuO was formed, whereas under Ar Cu/Cu2O (6) or Cu (8) was obtained. Complex 6 was used as CVD precursor for Cu and Cu‐oxide deposition (substrate temp., 400–500 °C, N2, 60 mL·min–1; O2, 60 mL·min–1; pressure, 0.87–1.5 mbar). The as‐obtained deposits show separated particles of different appearance at the substrate surface as evidenced by SEM. Non‐volatile 8 was applied as spin‐coating precursor for Cu and CuO formation [conc. 0.25 mol·L–1; volume 0.2 mL; 3000 rpm; depos. time 2 min; heating rate 50 K·min–1; holding time 60 min (Ar), 120 min (air) at 800 °C]. The samples on silicon consist of granulated particles (Ar) or are non‐dense with a grainy topography (air). EDX and XPS measurements confirmed the formation of Cu (Ar) or CuO (O2) with up to 13 mol‐% C impurity.
