“…By comparison to previously reported potentiometric biosensors, incorporation of PMA as an ion-exchanger in this work improved the selectivity for PG by~2-3 orders of magnitude, exhibited the lowest DL, and give the widest reported LDR. Graphene and MIP as novel classes of nanomaterials not only enabled the prepared sensors to achieve e nanomolar to sub-picomolar level, but also have many other applications in the field of energy production [28][29][30], energy storage [29,31,32], wastewater tretment [33], and biomedical application [34,35].…”

Pioglitazone Hydrochloride (PG) is an insulin‐sensitizing drug and is indicated for the treatment of type II diabetes. In this study, newly molecularly imprinted electrochemical sensors were constructed for the potentiometric determination of PG in the pharmaceutical formulations (Diabetonorm® 45 and 15 mg) with high accuracy and precision. The MIP particles (ionophore) were prepared by using the PG drug as a template, acrylamide (AC) or methacrylic acid (MAA) as a functional monomer, and ethylene glycol dimthacrylate (EGDMA) as a cross‐linker. The best MIP was synthesized from AC as a functional monomer, AC‐MIP. The best sensor (CPEs) was formulated from graphite (47 wt%) as a carbon source, AC‐MIP (5 wt.%) as an ionophore, PMA (1 wt%) as an ion‐exchanger, DNPOE (47 wt.%) as a conductive oil so‐called plasticizer. The best CPE electrode exhibited response slope to the Nernstian slope of 63.0 mV Decade−1, linear dynamic range of 10−8–10−4 M with the detection limit of 1.0×10−8 M, along with high reversibility, short response time 30 sec, and a long lifetime. The constructed biosensors showed high selectivity against similar interfering species (e. g. arabinose, galactose, lactose, maltose, glucose, Ba2+, Cu2+, Na+, Zn2+, Mg2+, Fe2+, Ca2+, NH4+).

“…Further on, with the carbon nanofiber electrodes, recently, self-supported electrodes with Ni/NiO and Pd nanoparticles are employed for HER/OER. 132 The best CNF-Ni/NiO-Pd electrode displayed the lowest overpotential (63 mV and 1.6 V at j = 10 mA/cm 2 ), a small Tafel slope (72 and 272 mV/dec), and an exchange current density (1.15 and 22.4 mA/cm 2 ) during HER and OER, respectively. Notably, these electrodes consist of graphitic layers that cover and protect the Ni/NiO NPs from corrosion.…”

Combining different material processing techniques is one of the keys to obtain materials that depict synergistic properties. In this review, we have reviewed a combination of two highly potential techniques, namely, electrospinning and atomic layer deposition (ALD), in the view of various applications. Over the past 10 years, our research groups are involved in the exploration of employing this combination for a range of applications. We also include some basic information on both the processes and diversity of nanostructures as a result of their combination. Nonwoven nanofiber membranes are excellent candidates for a wide range of applications. Also, they can act as templates to produce various other kinds of nanostructures when combined with ALD in small/large scale production. These nanostructures could be used as such or further subjected to other processing techniques yielding hierarchical structures. In this review, we exclusively survey and highlight the unique capabilities of combined electrospinning and ALD for applications in catalysis, photocatalysis, solar cells, batteries and gas sensors.

Nowdays, electrocatalytic water splitting has been regarded as one of the most efficient means to approach the urgent energy crisis and environmental issues. However, to speed up the electrocatalytic conversion efficiency of their half reactions including hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), electrocatalysts are usually essential to reduce their kinetic energy barriers. Electrospun nanomaterials possess a unique one‐dimensional structure for outstanding electron and mass transportation, large specific surface area, and the possibilities of flexibility with the porous feature, which are good candidates as efficient electrocatalysts for water splitting. In this review, we focus on the recent research progress on the electrospun nanomaterials‐based electrocatalysts for HER, OER, and overall water splitting reaction. Specifically, the insights of the influence of the electronic modulation and interface engineering of these electrocatalysts on their electrocatalytic activities will be deeply discussed and highlighted. Furthermore, the challenges and development opportunities of the electrospun nanomaterials‐based electrocatalysts for water splitting are featured. Based on the achievements of the significantly enhanced performance from the electronic modulation and interface engineering of these electrocatalysts, full utilization of these materials for practical energy conversion is anticipated.
