Microbially inoculated chars strongly reduce the mobility of alachlor and pentachlorobenzene in an alluvial sediment

Irina Jevrosimov et al.

Summary: The objective of this study was to investigate the transport behavior of two organic and persistent contaminants on alluvial sediment and the potential of microbially inoculated biochar and hydrochar as remediation techniques. The results showed that the retention time of the contaminants increased with increasing hydrophobicity, and the inoculated biochar increased the retardation of the compounds. Additionally, the bacterial counts increased in all experiments, indicating the potential for the removal of organic pollutants. Therefore, the addition of inoculated chars to contaminated sediments has the potential to inhibit the leaching of pollutants to groundwaters.

Room-Temperature Quantitative Quantum Sensing of Lithium Ions with a Radical-Embedded Metal-Organic Framework

Lei Sun et al.

Summary: Recent advancements in quantum sensing have led to transformative detection technologies with high sensitivity, precision, and spatial resolution. In this study, organic radicals integrated in a microporous metal-organic framework (MOF) were used as qubits for quantum sensing of lithium ions in solution at room temperature. The high surface area of the MOF enabled easy accessibility of the lithium ions to the organic qubits, allowing for unambiguous identification and quantitative measurement of their concentration using relaxo-metric and hyperfine spectroscopic methods based on electron paramagnetic resonance (EPR) spectroscopy. The sensing principle presented in this work can be applied to other metal ions with nonzero nuclear spin.

Hydrogel-Based, Dynamically Tunable Plasmonic Metasurfaces with Nanoscale Resolution

Jian Zhang et al.

Summary: This paper presents a general approach to developing tunable plasmonic metasurfaces with hydrogel meta-atoms at the subwavelength scale. The size of hydrogel nanodots can be reversibly controlled by absorbing or releasing water, resulting in humidity-responsive surface plasmon polaritons (SPPs) that generate plasmonic color rendering in the visible spectrum. The size variations of constituent hydrogel nanostructures enable broadband beam-steering on a phase modulator.

DNAzyme motor systems and logic gates facilitated by toehold exchange translators

Wenchan Deng et al.

Summary: This study reports a toehold-exchange translator and translator-mediated DNAzyme motor systems that enable sensitive responses to various nucleic acid targets using the same DNAzyme motor without requiring redesign. The translator efficiently converts nucleic acid targets into specific output DNA, activating the DNAzyme motor and enabling autonomous movement. By adjusting the target-binding region of the translator, the same DNAzyme motor system can respond to multiple nucleic acid targets. The study also demonstrates the construction and operation of four logic gates using the translator and DNAzyme motor, enhancing the biosensing applications of DNA motors.
