“…Compared with BCCF, it is easy to know that lots of oxygen-containing functional groups have been destroyed when BCCF−Fe 2 O 3 is synthesized, which is closely related to the decomposition and carbonization of cellulose. In addition, a weak band at 675 cm −1 is related to the stretching vibration of the Fe−O bond in BCCF−Fe 2 O 3 , 24 suggesting that lowcontent Fe 2 O 3 has been successfully introduced.…”

Structures and performances from nature provide ideas for humans to deal with energy and environmental crisis. Inspired from natural structures, bacterial cellulose nanofibers with a fine-meshed network were selected as the raw materials to design acetone gas sensors. Here, Fe 2 O 3 nanorods were successfully introduced on the surface of carbon nanofibers by a feasible hydrothermal catalytic carbonization at 120 °C. Lots of heterojunctions between the bacterial cellulose carbon nanofiber and the Fe 2 O 3 nanorod were constructed, resulting in high gas-sensing properties to acetone vapor. At room temperature, the response of Fe 2 O 3 /bacterial cellulose carbon nanofiber composite (BCCF−Fe 2 O 3 ) to 5 ppm of acetone reached 2060% within 10 s. BCCF−Fe 2 O 3 showed high sensitivity and selectivity, ppb-level detection limit (100.7 ppb), nice long-term stability (30 days), low energy consumption (1.4 μW), and good anti-humidity performance in acetone detection. To our surprise, BCCF− Fe 2 O 3 had realized ultrasensitive exhaled acetone detection within 16 s, proving an effective and inexpensive strategy for diabetic noninvasive diagnosis.

“…During the synthesis process, reducing and stabilizing agents such as sodium borohydride (NaBH 4 ), polyvinylpyrrolidone (PVP), sodium citrate (TSC), and maleic acid (MAH) were employed. However, it is worth noting that these agents, despite their effectiveness, possess toxicity and can negatively impact the optical properties as well as the biocompatibility of resulting nanomaterials [52][53][54].…”

In recent years, the conventional methods of synthesizing nanomaterials have been surpassed by the emergence of the microfluidics route, which has brought forth numerous advantages and transformed the domain of nanomaterial synthesis. However, the synthesis of semiconducting oxide nanomaterials, specifically Tin oxide (SnO2), remains a crucial area of research due to its remarkable advantages as a viable alternative to toxic and costly materials. Additionally, SnO2 quantum dots (QDs) exhibit immense potential across a diverse range of applications due to their exceptional optical and electrical properties. The existing synthesis methods for SnO2 QDs are either time-consuming or involve high-temperature conditions. To address these challenges, droplet-based microfluidic technique has emerged as a promising approach for the controlled synthesis of various semiconducting nanomaterials. This article highlights the synthesis of SnO2 QDs with tunable size through the utilization of a droplet-based microfluidic technique, providing precise control over droplet volumes. X-ray diffraction analysis verified the presence of rutile-type tetragonal structure in SnO2 QDs. From the transmission electron microscopy analysis, the average particle size was calculated to be 1.90 nm, 2.09 nm and 2.63 nm for the volume of droplet corresponding to 33.25 µl, 27.84 µl and 18.25 µl respectively. Furthermore, with a decrease in particle size a tunabilty in optical bandgap, from 4.60 eV to 4.00 eV was observed. This work provides insights into the influence of droplet volume on the particle size which in turn affects the associated properties of SnO2 QDs in a droplet-based microfluidic synthesis system.

Hybrid solar cells based on conductive polymer poly(o-toludine) (POT) with Cadmium Selenide nanoparticles (CdSe NPs) bulk heterojunctions (BHJ) were prepared by the direct mixing method and then the optical properties of the prepared materials were analyzed. The photovoltaic response of a hybrid film is studied by I –V measurements under simulated one-sun AM 1.5 illumination (100 mW cm-2). Three different CdSe load was tested to study the effect of CdSe loading on optical properties and efficiency of solar cell. Best ratio was 1:1 were gave 0.28 % efficiency. Also no photovoltaic effect for device with 75% CdSe load.
