“…The percentage of pyridinic N and graphitic N is so high that it can advance the electrocatalytic activity and chemical stability of NPCs. [ 48 ] The deconvolutions of the N1s spectra of NPC@MXene (Figure S4B, Supporting Information) exhibit an extra peak of pyridine‐ N ‐oxide compared to the N1s spectrum of NPC. This peak might exist due to chemical bonding between the oxygen‐containing functional groups of MXene and pyridine N of NPC.…”

Despite substantial progress in the development of wearable and flexible monitoring systems that conform to the epidermis, most designs focus on either physiological signs such as the electrocardiogram (ECG) results, respiration rate, or metabolites, and ignore the dynamic fluctuations of pH and temperature in sweat during on‐body tests. An advanced butterfly‐inspired hybrid epidermal biosensing (bi‐HEB) patch is presented here, which is interfaced with a custom‐developed miniaturized monitoring system. The patch incorporates a novel transducing layer of nanoporous carbon and MXene (NPC@MXene) for sensitive and durable detection of biomarkers in sweat. The bi‐HEB patch is composed of a glucose biosensor accompanied by pH and temperature sensors to precisely quantify glucose as well as two biopotential electrodes, allowing real‐time recording of electrophysiological (EP) signals. The NPC@MXene‐based glucose biosensor demonstrates an excellent sensitivity of 100.85 µAmm−1 cm−2 within physiological levels (0.003−1.5 mm), and variations in pH and temperature during on‐body perspiration monitoring are calibrated by employing a correction approach. In parallel, the EP electrodes exhibit skin‐electrode contact impedance and biopotential signals similar to those of conventional Ag/AgCl electrodes. Finally, the bi‐HEB patch integrated wearable system is used to accurately monitor sweat glucose and ECG of human subjects participating in indoor physical activities.

“…[ 45 ] The CNTs could not be produced by the pyrolysis treatment of single ZIF‐67 or ZIF‐8, while the thermal treatment of ZIF‐8@ZIF‐67 could yield a large amount of CNTs. This indicates that zinc evaporation under high‐temperature pyrolysis conditions accelerates the growth of CNTs, possibly catalyzed by Co. [ 46,47 ] From SEM, TEM, HAADF–STEM (Figure 1b,c,g‐l) and EDS mapping (Figure S3, Supporting Information), Co/Mo 2 C@NCNHP@S display a hollow polyhedral morphology with a large number of CNTs on the rough framework surface. Comparison sample NCNHP@S shows coiled carbon tubes on a collapsed metal‐organic frame (Figure S5, Supporting Information).…”

Al–S battery (ASB) is a promising energy storage device, notable for its safety, crustal abundance, and high theoretical energy density. However, its development faces challenges due to slow reaction kinetics and poor reversibility. The creation of a multifunctional cathode material that can both adsorb polysulfides and accelerate their conversion is key to advancing ASB. Herein, a composite composed of polyoxometalate nanohybridization‐derived Mo2C and N‐doped carbon nanotube‐interwoven polyhedrons (Co/Mo2C@NCNHP) is proposed for the first time as an electrochemical catalyst in the sulfur cathode. This composite improves the utilization and conductivity of sulfur within the cathode. DFT calculations and experimental results indicate that Co enables the chemisorption of polysulfides while Mo2C catalyzes the reduction reaction of long‐chain polysulfides. X‐ray photoelectron spectroscopy (XPS) and in situ UV analysis reveal the different intermediates of Al polysulfide species in Co/Mo2C@NCNHP during discharging/charging. As a cathode material for ASB, Co/Mo2C@NCNHP@S composite can deliver a discharge‐charge voltage hysteresis of 0.75 V with a specific capacity of 370 mAh g−1 after 200 cycles at 1A g−1.

“…After loading Au into ZIF-8, there is no significant loss of the crystallinity, suggesting that the integrity of ZIF-8 is maintained in the AuNPs/ZIF-8 composite. After heating, there are two distinct peaks at 25° and 44° for PCs (curve c), attributing to the carbon (002) plane and (101) plane, which are considered to be amorphous carbon [ 24 ]. Furthermore, for AuNPs/PCs, the spectrum is well matched with those of PCs and Au, which indicates that the AuNPs/PCs composite was successfully synthesized.…”

Electrochemical Aptasensor Based on Au Nanoparticles Decorated Porous Carbon Derived from Metal-Organic Frameworks for Ultrasensitive Detection of Chloramphenicol

A facile and sensitive electrochemical aptamer sensor (aptasensor) based on Au nanoparticles-decorated porous carbon (AuNPs/PC) composite was developed for the efficient determination of the antibiotic drug chloramphenicol (CAP). AuNPs modified metal-organic framework (AuNPs/ZIF-8) is applied as a precursor to synthesize the porous carbon with homogeneous AuNPs distribution through a direct carbonization step under nitrogen atmosphere. The as-synthesized AuNPs/PC exhibits high surface area and improved conductivity. Moreover, the loading AuNPs could enhance the attachment of the aptamers on the surface of electrode through the Au–S bond. When added to CAP, poorly conductive aptamer-CAP complexes are formed on the sensor surface, which increases the hindrance to electron transfer resulting in a decrease in electrochemical signal. Based on this mechanism, the developed CAP aptasensor represents a wide linear detection range of 0.1 pM to 100 nM with a low detection limit of 0.03 pM (S/N = 3). In addition, the proposed aptasensor was employed for the analysis of CAP in honey samples and provided satisfactory recovery.
