“…Recently, using an organic acid as both a coordinating reagent and a soft template has been an effective way of fabricating metal oxides [21,22]. Studies have shown that boric acid is capable of coupling with the metal ions of Pb 2+ , Cd 2+ , and Fe 2+ to form nanosheet complexes [23][24][25]. Carboxylphenyl boronic acid was reported to complex with metal ions (such as Zn 2+ , Cd 2+ , Ni 2+ , abd Ln 3+ ) to form 2D coordination polymer nanosheets [26,27].…”

As a typical spinel ferrite, NiFe2O4 is suitable for use in gas sensors. Herein, we report the fabrication of porous, tremella-like NiFe2O4 assembled using porous, ultrathin nanosheets via the coordination of Ni2+ and Fe2+ with 1,4-phenylenediboronic acid. The optical band gap of the NiFe2O4 is estimated to be about 1.7 eV. Furthermore, the NiFe2O4 sensor annealed at 400 °C exhibits a low detection limit of 50 ppb, a fast response/recovery time (11.6 s/41.9 s to 10 ppm toluene), good reproducibility, and long-term stability at 220 °C. The suitable sensing performances can be attributed to the good catalytic activity of NiFe2O4 to toluene oxidation. Moreover, the ultrathin nanosheets with porous structures provide a large number of active sites to significantly favor the diffusion and adsorption/desorption of toluene molecules. This current work provides an insight into fabricating NiFe2O4 using 1,4-phenylenediboronic acid, which is promising for ppb-level toluene detection.

“…These properties provide diverse applications in opto-electronic technologies such as laser frequency conversion [4], optical parameter oscillation [5] and signal communication [6]. Lead borates are of special interest in the search for borate materials, since these compounds have pronounced radiation shielding properties [7][8][9].…”

Amorphous lead metaborate (Pb(BO2)2 H2O) nanostructures were synthesized by a simpl and cost-effective synthesis method which is based on precipitation of lead ions using boric acid/sodium hydroxide buffer (pH 9.2) in the presence of polyethylene glycol (PEG). Scanning electron microscopy images showed that the average particle size is 30±9 nm and the particle shape is mostly spherical. The chemical formulation of Pb(BO2)2 H2O was confirmed by infrared spectroscopy, inductively coupled plasma and thermal gravimetric analysis (TGA). The percentage of PEG molecules on the particle surface equal to 2.5 % was determined by TGA. Optical reflectance measurement was performed by UV-Vis spectroscopy. Based on the Kubelka-Munk function, it was calculated that the Pb(BO2)2 H2O nanostructures have a direct band gap of 4.6 eV.

The design and fabrication of surfaces that are not wetted either by water or oil holds much significance for the energy infrastructure, particularly where corrosion represents a significant problem and cleaning, maintenance, and repair of containers, pipelines, and processing equipment is difficult or poses safety hazards. Nature has numerous examples of surfaces that resist fouling by repelling liquid (especially water) droplets. Designing a surface that is not wetted by low‐surface‐tension liquids such as hydrocarbons is a considerably more difficult task that is beyond the capabilities of most natural systems since the cohesive forces within such liquids are low and most interfacial interactions induce the spreading of oil droplets. A combination of hierarchical texturation, reentrant curvature, and low surface energy is thought to be necessary to design omniphobic surfaces. However, such surfaces are often constructed from polymers and thus prone to thermal degradation. In this contribution, we illustrate the modular design and development of a biomimetic architecture incorporating micro‐ and nanoscale texturation on etched carbon steel. Etching of the steel substrate endows microscale roughness; the substrate is further coated with ZnO nanotetrapods to define nanoscale texturation and further modified to expose pendant fluorous groups. The highly textured substrates exhibit simultaneous superhydrophobic and superoleophobic behavior. The utilization of ZnO nanotetrapods with protruding arms gives rise to a nanotextured morphology regardless of the specific orientation of the nanostructures and allows for the trapping of air pockets, thereby suspending liquid droplets as per the Cassie–Baxter mode. The textured ceramic/metal surfaces are stable up to high temperatures and are well adhered to the metal substrate upon application of a conformal amorphous SiO 2 coating. The incorporation of multiple design elements—microscale roughness, nanotexturation, a “cementing” layer, and surface modification with low‐energy pendant perfluorinated chains—provides considerable versatility and tunability for specific liquid‐handling conditions. The strategy described here is generalizable to other modes of texturation and surface modification and can be broadly adapted to prevent wettability of a surface by a specific liquid, thereby allowing for protection of components exposed to corrosive fluid environments.
