Summary: The behavior of porphyrin derivative floating film molecules was significantly influenced by the presence of L-proline amino acid dissolved in the subphase, while D-proline had only a slight influence. This chirality-driven selection was preserved through the Langmuir-Schaefer method, but not with the spin-coating technique. These results provide proof of concept for active molecular layers for chiral discrimination and emphasize the crucial role of the deposition technique on the features of the sensing layers.

Summary: This study investigated the interfacial behavior of phospholipid-porphyrin (Pl-Por) conjugates and their dependence on the porphyrin type and alkyl chain length. The results showed that Pl-Por conjugates can form stable monolayers at the air/water interface, and the packing of the monolayer is influenced by the porphyrin type. The length of the alkyl chain determines the structure of the formed domains.

Summary: This study investigated the effects of potassium ions on the surface properties of Amphotericin B (AmB) using the Langmuir monolayer method. The results showed that potassium ions enhance the influence of AmB on membrane stability at low surface pressures but weaken it at high surface pressures. Potassium ions also significantly interfere with the interaction between AmB and the cholesterol-enriched region.

Summary: This study explores a-IGZO split-channel dual-gate high-voltage thin film transistors (HVTFTs) with potential applications for high-voltage and high breakdown voltage. The typical HVTFT structure of drain offset degrades ON-current. Experimental results show that high ON-current induced thermal breakdown is the main reason limiting the breakdown voltage of dual-gate HVTFTs. The introduction of split-channel structure enhances heat dissipation and achieves higher breakdown voltage for dual-gate HVTFTs.

Summary: This work investigated the influences of mirror-field and closed-field magnetic field configurations on plasma parameters and ion flux dynamics in dual magnetron reactive high power impulse magnetron sputtering with Al targets in Ar/O-2 mixture. The study found that the plasma compositions were similar in both configurations, but the closed-field discharge had higher electron density and lower plasma potential compared to the mirror-field discharge. The ion energy distribution functions showed different peak energies and ion fluxes between the two configurations, with the mirror-field discharge peaking at the end of the pulse and the closed-field configuration reaching peak fluxes 10 µs after pulse termination.

Summary: The rapid and sensitive detection of heavy metal ions is crucial for food safety and the environment. Carbon quantum dots-based probes, M-CQDs, and P-CQDs, were developed for the detection of Hg2+ using fluorescence resonance energy transfer and photoinduced electron transfer mechanisms. The M-CQDs exhibited fluorescence quenching, while the P-CQDs showed fluorescence enhancement upon the addition of Hg2+. Paper-based chips modified with M/P-CQDs were successfully used for visual Hg2+ sensing, enabling real-time detection in tap water and river water samples.

Summary: This research focuses on the development of pH indicators based on the quinoxaline signaling group for measuring acidic aqueous solutions (pH 1-5). A specific quinoxaline derivative, QC1, with hydrophilizing substituents was synthesized and found to be soluble in water within the pH range of interest. This derivative exhibits shifts in absorption and emission bands in response to external stimuli, making it suitable for optical measurements. It is also capable of detecting metal cations without interference and can be easily observed with the naked eye, allowing for rapid semi-quantitative analyses.

Summary: The development of flexible strain sensors has focused on achieving high strain percentages and sensitivity. However, capacitance-based sensors are typically limited in sensitivity due to the Poisson effect. By using auxetic structures, the sensitivity of capacitance sensors has been improved, making them more competitive. This study presents the first use of helical auxetic yarns as capacitive sensors and explores the factors that affect their response to strain.

Summary: Detection of nitroaromatic compounds (NAC) is important due to their hazardous nature. A new pyrene-imidazoporphyrin dyad is reported to exhibit an unusual 'turn-on' response to NAC with the appearance of a new band attributed to exciplex emission. The dyad's porphyrin backbone allows for ratiometric detection using its own fluorescence as an internal reference signal. Association constants of the dyad are reported to be in the order of 10(4) M-1.

Summary: The associative behavior of geometrically anisotropic meso-(4-octadecyloxy-phenyl)-boron-dipyrrin (BODIPY) was studied spectroscopically in binary solvent mixtures and upon compression in Langmuir floating layers. Different steady and excited state species were observed during monolayer compression and facilitated aggregation in water/acetonitrile systems. The findings highlight the need to consider system-specific factors when making generalizations about aggregating systems. Various decay fitting models were examined for the analysis of dye aggregates, with the radiative constant gamma-distribution approach and the maximum entropy method (MEM) showing superior performance for complex fluorescence decay analysis. MEM is recommended for systems with complicated lifetime distributions over time or under external stimuli. The findings and protocols can be used as tools for studying the photophysics of steady and excited-state BODIPY aggregates.

Summary: This study focuses on the development of optical sensors for acidity measurements in low-pH aqueous solutions. Different hydrophilic-lipophilic balance (HLB) quinoxalines were prepared and investigated as molecular components of pH sensors. Immobilization of these quinoxalines in agarose and Langmuir-Blodgett (LB) and Langmuir-Schafer (LS) techniques allows for the fabrication of pH responsive polymers, paper test strips, and emissive films with excellent stability. These dual-responsive pH sensors enhance the accuracy of pH measurements, particularly in complex environmental samples.
