Summary: This article describes a leaf-mounted sensor that detects condensing water vapor from leaf transpiration and monitors incident solar radiation by utilizing the temperature difference between the leaf and the sensor plate. The device provides a low-cost method to assess the water status of plants by comparing the diurnal patterns of leaf transpiration and solar irradiance. A strong correlation between condensation and irradiance is observed under unrestricted water supply conditions, while a deviation in their patterns likely indicates suboptimal plant water status.

Summary: This paper introduces a wearable plant sensor that can directly monitor methanol emission on plant leaves in field conditions. The sensor technology used in this study eliminates the need for complex sampling and expensive instruments. By using a composite of conducting polymer microcrystallites and platinum nanoparticles, the sensor exhibits high sensitivity and selectivity for detecting methanol emissions. The integration of the sensor into a gas collection chamber with a hydrophobic gas diffusion membrane minimizes the influence of environmental humidity on the sensor performance. The experiments conducted with maize plants demonstrate the promising application of this sensor in monitoring methanol emission concentrations between different genotypes.

Summary: We report a soft and stretchable resistive strain sensor with high sensitivity, large sensing range, and high robustness. The sensor is made of a silver nanowire network embedded below the surface of an elastomeric matrix. By applying periodic mechanical cuts to the top surface, the current flow in the sensor can be changed from uniform to along the conducting path defined by the open cracks. This stretchable strain sensor can be integrated into wearable systems for monitoring physiological functions and body motions associated with different levels of strain, such as blood pressure and lower back health.

Summary: This paper demonstrates the room-temperature thermal modulation in 2.5 mm-thick Pb(Mg1/3Nb2/3)O-3-xPbTiO(3) (PMN-xPT) single crystals. Through the use of advanced poling conditions and a systematic study on composition and orientation dependence, a range of thermal conductivity switching ratios, with a maximum of approximately 1.27, is observed. The simultaneous measurements of piezoelectric coefficient (d(33)), domain wall density using polarized light microscopy (PLM), and birefringence change using quantitative PLM reveal an increase in domain wall density at intermediate poling states (0< d(33)< d(33(max)) compared to the unpoled state.

Summary: We use a hybrid diffusion- and nucleation-based kinetic Monte Carlo model to explain the significant influence of adatom diffusion on incipient surface dislocation nucleation in metal nanowires. We discover a stress-regulated diffusion mechanism that promotes the accumulation of diffusing adatoms near nucleation sites, explaining the experimental observations of temperature-dependent nucleation strength but weak strain-rate dependence. Additionally, our model shows that a decreasing rate of adatom diffusion with increasing strain rate leads to stress-controlled nucleation becoming the dominant mechanism at higher strain rates. Overall, our model provides new mechanistic insights into how surface adatom diffusion directly affects the nucleation process and mechanical properties of metal nanowires.

Summary: The transmission of pathogens through contact with contaminated surfaces is a significant route for the spread of infections, including the recent outbreak of COVID-19. Disinfection and sanitization are commonly used methods, but they have limitations such as antibiotic resistance and viral mutation. Peptides have been studied as a potential alternative due to their ability to interact with microorganisms and their applications in drug delivery and immunomodulation. This study focuses on antiviral coating strategies and their applications in personal protective equipment, healthcare devices, textiles, and public surfaces.

Summary: In this study, researchers discovered that CRISPR-Cas12a can induce nonspecific trans-cleavage of dsDNA substrate, and the location of the overhang on the substrate affects its susceptibility to trans-activated Cas12a. They attributed this preference to the directional trans-cleavage behavior of Cas12a. They also used this finding to design a hybrid DNA reporter for a sensitive CRISPR-Cas12a detection platform.
