Summary: A series of ratiometric two-photon fluorescent Zn2+ sensors based on quinoline and DPA moieties has been designed to improve the two-photon absorption (TPA) response of a newly synthesized probe. The designed probes show enhanced TPA intensities at longer wavelengths due to increased intra-molecular charge transfer. Moreover, the incorporation of an acyl unit and a dimethylamino terminal has further improved the TPA cross sections and fluorescence quantum yields of the probes. The designed probes demonstrate potential as ratiometric two-photon fluorescent probes with enhanced TPA intensities, large differences of emission wavelength upon Zn2+ coordination, and strong fluorescence intensity.

Summary: In this work, the fluorescence of rhodamine B (RhB) was found to be significantly reduced after it bound to hemin/G-quadruplex and reacted with center dot OH. Based on this finding, a colorimetric and fluorescent dual-mode sensing platform was designed for visual detection of hydrogen sulfide (H2S). The dual-mode assay showed high selectivity toward H2S with a low detection limit and demonstrated promising potential for on-site visual detection of H2S.

Summary: A hydroxyl-decorated in-plane micro-mesoporous silica nanosheet is developed as an ion sieve to regulate the plating/stripping behavior of zinc ion. The presence of the silica ion sieve leads to an extremely long cycle lifespan for Zn//Zn cells and exhibits stability in Zn//NaV3O8 center dot 1.5H(2)O full cells and Zn//AC hybrid capacitors. This strategy can also be applied to inhibit dendrite growth in lithium metal anodes.

Summary: Cyan light-emitting Ce0.985-xZnxO2:0.015 Tb3+ (x = 0 to 0.2) phosphors were synthesized using an ethylenediaminetetraacetic acid-assisted hydrothermal method. The incorporation of Zn2+ ions increased the Ce3+/Ce4+ ratio and enhanced the oxygen vacancies in the phosphors. The phosphors showed potential for temperature sensor applications with moderate temperature sensitivity, negligible hysteresis loop, and excellent reversibility.

Summary: This study developed an intravital ratiometric analysis method to measure the extracellular calcium ion concentration and pH in mouse bone marrow. The researchers found that the average calcium ion concentration in the bone marrow was not significantly different from the blood serum, but HSCs were located in areas with elevated local calcium ion concentration. With aging, there was a significant increase in calcium ion concentration in M-type cavities.

Summary: The development of bright fluorescent nanoparticles is essential for improving the resolution and signal-to-noise ratio in fluorescence imaging techniques. In this study, we developed FRET-based nanovesicles with different dye loadings and investigated their optical properties at the nanoscopic level. The results show that the dye's molecular diffusion in fluid-like membranes can modulate the optical properties of the nanoparticles, resulting in highly efficient and stable nanoprobes.

Summary: This study continues the development of virtual tensile test for molecular crystals, focusing on different polymorphs with varying mechanical properties. The study shows that the properties of these polymorphs depend on the crystal packing and the topology of hydrogen and halogen bonds. New polymorphs of 4-bromophenyl 4-bromobenzoate crystal structures are predicted through global minimization of lattice energy. The proposed methodology successfully identifies the known polymorphic forms and confirms their mechanical properties computationally.

Summary: In this study, we focus on the mechanical behavior of three polymorphic forms of 6-chloro-2,4-dinitroaniline crystals. Through analyzing the anisotropy of mechanical properties, crystal structure changes during stretching, and relaxation of stretched structures, we find distinct differences in mechanical behavior among the three forms. The sliding of molecular layers and reconfiguration of interlayer bonds contribute to the structural changes in Form I, while the plastic behavior of Form II is attributed to the mobility of strong noncovalent bonds. Form III exhibits the least anisotropy in elastic moduli and demonstrates the possibility of self-healing. Multiple analysis methods are necessary for accurately predicting the mechanical properties of molecular crystals.

Summary: Hemorrhage is a significant aspect of traumatic brain injury (TBI), and alcohol consumption prior to TBI can alter iron regulation, exacerbate TBI-induced microglia activation, and sustain the expression of regulatory proteins for several days post-injury. Additionally, microglia may play a role in iron management through red blood cell clearance. This study provides valuable insights into the relationship between alcohol and TBI, as well as the importance of iron management in brain injury recovery.

Summary: The isotropic electrostatic polarizability of sub-nanosized magnesium clusters was studied, and a linear correlation was found between the polarizability of the most favorable isomers and the cluster nuclearity. Furthermore, the most stable cluster isomers demonstrated minimal polarizability values. These observations are independent of the cluster structures and may be related to the energetic favorability of the cluster structure. The significance of these trends for cluster structure prediction and practical applications is discussed.

The study also investigated the stability and optical gain potential of the derivatives, as well as their two-photon absorption properties. Quantum-chemical calculations were performed to analyze the electronic nature of these coumarins, which showed agreement with experimental data.
