Direct methanol fuel cell (DMFC) is a sustainable energy conversion device that is known for its advantages in terms of portability as well as can be stored and transported safely. Functionalized nanostructured materials have been used in proton exchange membrane (PEM) for DMFC applications to enhance the proton conductivity and suppress the methanol permeability. In this study, conductive polyaniline deposited oxidized graphitic carbon nitride (PANI-O-g-C 3 N 4 ) was incorporated in sulfonated poly (ether ether ketone) (SPEEK) membrane for DMFC applications. The performances of graphitic carbon nitride (g-C 3 N 4 ) and oxidized graphitic carbon nitride (O-g-C 3 N 4 ) on SPEEK PEM were also assessed and compared. The morphological and X-ray diffraction analysis indicated that the structure and crystallinity were altered with the deposition of PANI on g-C 3 N 4 . The scanning electron microscopy and topography analysis revealed that the existence of g-C 3 N 4 and functionalized g-C 3 N 4 were clearly seen on the surface of the SPEEK membrane. Water uptake capacity and ion exchange capacity were significantly improved in the functionalized g-C 3 N 4 -modified SPEEK membrane (O-g-C 3 N 4 /SPEEK and PANI-O-g-C 3 N 4 / SPEEK). The lower methanol permeability and higher proton conductivity of 3.71 Â 10 À7 cm À2 S À1 and 5.34 Â 10 À3 S cm À1 were recorded by 0.1 wt% PANI-O-g-C 3 N 4 incorporated SPEEK membrane. Functionalized g-C 3 N 4modified SPEEK membrane also exhibited higher oxidative stability. The performance of the PANI-O-g-C 3 N 4 incorporated SPEEK membrane in DMFC application highlights its potential as a superior nanofiller for the modification of PEM.

Summary Platinum‐based catalysts are regarded as premier anodic electrocatalysts in direct methanol fuel cells due to their great catalytic activities but hampered by its non‐benign conventional synthesis, and high production expenses. This study exploited a new sustainable pathway of a biosynthesis route using the biomass plant extract of sugarcane bagasse in a facile single‐step process guided by the principle of green chemistry performing enhanced functionalized bio‐platinum nanoparticles. The physiochemical characterization, along with the bio‐reductive mechanism were comprehensively discussed. The electrochemical activity was performed by cyclic voltammetry, chronoamperometry, and electrochemical impedance spectroscopy measurements. The novel nano‐spheroid biosynthesized Pt NPs manifested a high ECSA of approximately 95 m2/g with an enhanced current density of 400 mA/mgcatalyst−1, which were 3 to 4 times higher than those of Pt black commercial. The discovery of bioactive compounds from the dominant group of polyphenolics, flavonoids, carboxylic acids, and proteins suggested that they were accountable for the bio‐reductive mechanism.

“…For some applications, temperature control is one of the essential manipulations. − For example, the exponential increase of target deoxyribonucleic acid (DNA) in the PCR process requires repeated cycling of a sample by high-temperature denaturation (367–371 K), low-temperature annealing (323–338 K), and middle-temperature extension (343–353 K). , Some ways have been reported to successfully control the temperature of microfluids in microfluidic devices. For example, Dinca et al used Pt thin layers as heaters incorporated in microfluidic chips to control thermal cycles.…”

Temperature control is one of the essential operations in droplet-based microfluidics. Light based on the photothermal effect is very suitable to heat a droplet because of noncontact and local heating. However, it is unable to predict the droplet temperature precisely. This paper reports an infrared laser to heat a droplet in a microchannel based on the photothermal effect for temperature control. The numerical method is applied to simulate the thermocapillary flow and heat transfer of this heating process. Particular attention is paid to the impact of laser beam size and input power on the droplet’s temperature distribution, heat transfer, and thermocapillary flow. The results show that increasing the laser power and decreasing the laser beam size increase the average temperature and thermocapillary flow due to the increase in the actual absorbed energy. The heat transfer coefficient of the droplet interface increases with the decrease of the laser beam size due to weakening of thermocapillary flow. It is also found that the nonuniform temperature coefficient reduces when the input power and the laser beam diameter increase, and the expression of the average temperature increase is obtained by considering the effects of the laser power and the laser beam diameter. With the obtained expression of the average temperature, a thermal cycle of polymerase chain reaction (PCR) amplification, a laboratory technique used to make multiple copies of a segment of deoxyribonucleic acid (DNA), can be successfully obtained. The results of this work will provide support for temperature control and applications, such as PCR amplification, in droplet-based microfluidics.
