Summary: Here, a new method is presented for accurate in-situ monitoring of hydrogel swelling in real-time using single-sided nuclear magnetic resonance (NMR) profiling. The method reduces experimenter bias and uncertainty intrinsic to common weighing and caliper methods. NMR profiling additionally provides dynamic swelling rates over time, without needing to touch or modify the sample.

Summary: This study explores the use of a benchtop low-field single-sided NMR to determine the species distribution in complex aqueous-organic systems known as Winsor III. The results show that the salinity of the aqueous phase affects the species distribution in the bicontinuous system, and the methodology used provides information at both macroscopic and microscopic levels. Additionally, the study demonstrates the ability of single-sided NMR to determine the phases' dimensions and the species distribution in a polymer-based bicontinuous system.

Summary: In this study, single-sided 1H NMR relaxometry was used to characterize the molecular environments in both dry and wet acrylic paints by their molecular mobilities. Two different relaxation behaviors were identified in dry paint, indicating regions of greater and lesser mobility, attributed to amorphous and crystalline domains of the semi-crystalline acrylic polymer. In wet paint, two different relaxation behaviors were characterized, hypothesized to come from unique molecular environments in the acrylic binding medium, along with two simultaneous exchange processes involving aqueous solvent.

Summary: Due to its mobility and ability to investigate exposed surfaces, single-sided (SiS) nuclear magnetic resonance (NMR) technology opens up new possibilities in the field of geosciences. This study compares SiS NMR data with conventional laboratory NMR data and shows that SiS NMR tends to slightly overestimate pore size distributions. However, SiS NMR can still be useful in assessing hydro-mechanical properties and providing soil moisture data for regional-scale calibration.

Summary: Objective: A single-sided magnet system is developed for measuring Magnetic Resonance relaxation and diffusion parameters. Methods: This system uses an array of permanent magnets to optimize magnet positions and produce a homogeneous B-0 magnetic field that can project into a sample. Results: The magnet produces a 0.2 T field and can measure T-1, T-2, and ADC parameters. In-vivo studies show its potential for non-invasive measurements in the brain, such as monitoring T-2 during cerebral hypoxia.

Summary: This study evaluated the use of non-destructive portable NMR for the characterization and preservation state of waterlogged archaeological wood samples from the Roman period. The results of this multi-analytical approach allowed the quantification of relaxation times and diffusion water components affected by degradation products, such as fungi and microstructural changes, in both softwood and hardwood samples. The findings will contribute to the improvement of single-sided NMR protocols for in situ analysis of archaeological wood with portable NMR technology.

Summary: This study investigated the potential of PVA-borax hydrogel for cleaning limestones and found that the cleaning effectiveness strongly depends on the porosity of the stones. Different responses were observed in Lecce stone, Travertine perpendicular cut, and Travertine parallel cut, suggesting that the effectiveness of the cleaning varies based on the type of rock.

Summary: This paper introduces a novel method for using single-sided NMR to measure the water content of building materials. The NMR signal intensity and water content of brick, sandstone, mortar, and concrete were measured using a single-sided NMR-MOUSE PM25 and a high-precision electronic scale. The NMR signal intensity and water content data for each material were fitted using the least squares method, and the results showed that these relations are universal for building materials and independent of the measurement environments.

Summary: A hand-held, single-sided nuclear magnetic resonance (NMR) sensor was designed to quickly assess burn depth and detect full-thickness skin. The sensor consists of a single-sided magnet, a radio frequency coil, a matching circuit, and an aluminum shell. The optimization of the permanent magnet array using the sparrow search algorithm (SSA) resulted in low vertical gradient strength and maximal uniformity in field of view (FOV) for each layer. The experimental results of the depth-transverse relaxation time (T-2) map proved that this sensor is highly sensitive in distinguishing deep dermal and full-thickness burns, as well as superficial partial-thickness burns.

Summary: The matrix pencil method (MPM) is tested for quantitatively processing multiexponential low-field nuclear magnetic resonance T1 relaxometry data. The data is obtained from T1 saturation recovery curves measured in a highly inhomogeneous magnetic field. Different concentrations of a Gd3+ contrast agent doped in 0.9% brine solutions are used as test liquids. MPM shows superior performance in separating and quantifying relaxation components, as well as exploring the sensitivity to relative contribution of each component and resolving systems with multiple components.

Summary: Understanding aging phenomena of alternative fuels is crucial due to the introduction of different aging-related phenomena. A novel test rig was designed to simulate real conditions and achieve knowledge gain for fuel aging and additive technology development. The results showed that pure FAME performed well in the realistic setup due to its high polarity preventing deposit accumulation. Insightful information with minimal effort and sample volume was obtained through benchtop 1H Nuclear Magnetic Resonance (NMR) spectroscopy. Conventional fuel and FAME blends were found to lead to system failures and large quantities of deposits.
