Summary: Methods combining spatially patterned activation of a photoreductant and interferometric scattering microscopy enable fast, label-free monitoring and control of hundreds of gold nanoparticles. The kinetics of individual particle growth follow a two-step nucleation-autocatalysis model with a distribution of rate constants that vary with reaction conditions.

Summary: The construction industry, one of the largest industries worldwide, has low efficiency and labor productivity compared to other sectors. Recent studies have demonstrated the importance of automation in improving efficiency and safety in construction projects. This paper provides a comprehensive review of real-time monitoring in construction projects, focusing on sensor technologies and methodologies for mapping, understanding, positioning, and tracking of construction activities. Various case studies of applying these technologies for hazard identification, monitoring worker behavior, and assessing the construction environment are also covered.

Summary: The skin is the largest organ of the human body, and wounds can have severe consequences, such as morbidity and mortality. Infections in wounds are common and can delay healing and lead to sepsis. This study presents a novel strategy for pH sensing in wound dressings made from bacterial nanocellulose, which can facilitate early detection of infection. The pH-responsive nanocomposites showed excellent properties as wound dressings and could be used for encapsulation and release of bioactive compounds for the treatment of difficult-to-heal wounds, promoting the development of innovative wound care materials.

Summary: It is crucial to study the compositional evolution of nanoparticles during electrochemical reactions in order to understand the structure-performance relationship and design nanomaterials for specific applications. The plasmonic scattering interferometry microscopy (PSIM) is a powerful optical imaging method that allows real-time tracking and quantification of the compositional changes of single nanoparticles during aqueous electrochemical reactions.

Summary: The study utilized near-real-time satellite precipitation estimates to analyze the spatiotemporal pattern of rainfall caused by typhoon Lekima in China. It was found that IMERG-Late and CMORPH-RT performed better under higher rain rates, with IMERG-Late showing benefits from DPR and GMI inputs, and CMORPH-RT reducing its IR inputs. Additionally, extreme precipitation events were linked to precipitation columns around the storm center.

Summary: Bulk magnetic materials have multidomain structure, but at the nanoscale, single domain magnetic crystals displaying superparamagnetic behavior with strong magnetization can be obtained. By manipulating the physical, chemical, and biological properties of superparamagnetic nanoparticles (SPMNPs) through surface modification, versatile nanoplatforms with exciting tunable characteristics and multimodal functionalities for diverse applications can be created. This systematic review article provides valuable insights into the capabilities and applications of SPMNPs in biomedical, environmental, energy, and mechanical fields.

Summary: Gallium Nitride (GaN) based humidity sensor was fabricated using pulse modulated DC magnetron sputtering, with interdigitated electrodes (IDEs) to enhance sensitivity. The sensor exhibited linear impedance response, high sensitivity, and fast response and recovery times, showing little hysteresis and good stability for accurate measurements. Experimental results demonstrated its effectiveness in evaluating plant transpiration cycle and monitoring freshness level of food products, making it a promising candidate for future electronics applications.

Summary: In this study, the electrical conductivity of the supporting substrate was employed as an indicator to monitor the real-time evaporation rate of an interfacial solar evaporator (ISE). The method showed wide applicability for different types of ISEs and could sensitively detect salt clogging in the ISE earlier than traditional methods. This in situ evaporation rate monitoring has important implications for the intelligent management of large-scale ISEs.

Summary: In this study, a combination of electrochemical techniques and quartz crystal microbalance with dissipation monitoring (QCM-D) in one analysis setup (EQCM-D) was used for the first time to monitor the real-time CaCO3 deposition and provide kinetic details. The results showed that a lower applied voltage led to more CaCO3 mass deposition and thicker deposited layer, while increasing Ca2+ and HCO3- concentrations resulted in higher deposition amounts. Mg2+ addition led to a significant reduction in the deposition rate of CaCO3 due to its inhibiting effect on growth sites.

Summary: In this study, a heparin-based nanoparticle system was successfully developed by engineering superparamagnetic iron oxide nanoparticles (SPIONs) with an organic coating composed of low molecular weight heparin (LMWH) and bovine serum albumin (BSA). The system showed promising potential for targeted theranostic applications and demonstrated enhanced antitumor effects when loaded with the chemotherapeutic agent paclitaxel (PTX). Furthermore, the nanoparticles exhibited effective inhibition on the heparanase enzyme and showed comparable relaxivity values to commercial contrast agents, indicating their potential in magnetic resonance imaging (MRI).
