“…Figure S10 also illustrates the MESP distribution of TC, ofloxacin, enrofloxacin, kanamycin, norfloxacin, and chloromycetin. MESP can be used to describe the possible active sites of the reaction and identify the regions prone to electrostatic interaction during the adsorption process. − The positively charged areas are depicted in red, while the negatively charged areas are represented in blue. Table S4 also compares the maximum MESP values of various antibiotics.…”

A self-powered photoelectrochemical (PEC) sensor based on a Ti 3 O/rutile TiO 2 (Ti 3 O/R-TiO 2 ) heterophase junction nanocomposite is constructed for a highly sensitive and specific detection of tetracycline (TC). The Ti 3 O/R-TiO 2 heterophase junction is successfully grown in situ on a Ti substrate via a onestep calcination method. XRD and Rietveld refinement results confirm that the contents of Ti 3 O and R-TiO 2 can be tuned by the adjustment of the calcination temperature. Benefiting from the improved generation and separation of photogenerated electron− hole pairs as a result of the introduction of metallic phase Ti 3 O and heterophase junction, the Ti 3 O/R-TiO 2 photoelectrode prepared at 700 °C (Ti 3 O/R-TiO 2 -700) and beyond presents much higher photocurrent density than the photoelectrode with pure R-TiO 2 under light irradiation. More importantly, a self-powered PEC sensor with good performance was constructed for TC detection by using Ti 3 O/R-TiO 2 -700 as a photoelectrode. This PEC sensor displays a wide working range (3−300 μM) and a low detecting limit (0.039 μM) as well as good sensitivity. Additionally, a possible charge separation mechanism over the Ti 3 O/R-TiO 2 heterophase junction is also proposed. This work provides valuable insight into the design and development of high-performance photoelectrodes through the modulation of crystal phases in nanocomposites for highly effective chemical sensors.

“…35 Such functional ZIF-based materials have excellent application potential in uranium adsorption. 36 Nevertheless, the preparation of most existing functionalized ZIF-based adsorbents has the characteristics of being time-consuming and complex, attributed to the multi-step grafting or oxidation processes in the modification process. 35 Therefore, it is significant to exploit rapid and convenient methods to prepare a functionalized ZIF-based adsorbent for uranium adsorption.…”

“…[ 1 ] They sense external stimuli, such as pressure, [ 2 ] strain, [ 3 ] and temperature, [ 4 ] and convert them into electrical signals. Hydrogels, hydrophilic 3D network‐structure gels with good biocompatibility and super elasticity, [ 5 ] are promising candidates for wearable electronics. [ 6 ] However, conventional hydrogels frequently rupture during stretching, due to their weak mechanical properties; this limits their practical application.…”

Conductive hydrogels exhibit high potential in the fields of wearable sensors, healthcare monitoring, and e‐skins. However, it remains a huge challenge to integrate high elasticity, low hysteresis, and excellent stretch‐ability in physical crosslinking hydrogels. This study reports the synthesis of polyacrylamide (PAM)‐3‐(trimethoxysilyl) propyl methacrylate‐grafted super arborized silica nanoparticle (TSASN)‐lithium chloride (LiCl) hydrogel sensors with high elasticity, low hysteresis, and excellent electrical conductivity. The introduction of TSASN enhances the mechanical strength and reversible resilience of the PAM‐TSASN‐LiCl hydrogels by chain entanglement and interfacial chemical bonding, and provides stress‐transfer centers for external‐force diffusion. These hydrogels show outstanding mechanical strength (a tensile stress of 80–120 kPa, elongation at break of 900‐1400%, and dissipated energy of 0.8–9.6 kJ m−3), and can withstand multiple mechanical cycles. LiCl addition enables the PAM‐TSASN‐LiCl hydrogels to exhibit excellent electrical properties with an outstanding sensing performance (gauge factor = 4.5), with rapid response (210 ms) within a wide strain‐sensing range (1–800%). These PAM‐TSASN‐LiCl hydrogel sensors can detect various human‐body movements for prolonged durations of time, and generate stable and reliable output signals. The hydrogels fabricated with high stretch‐ability, low hysteresis, and reversible resilience, can be used as flexible wearable sensors.
