Summary: In this paper, a physics-informed neural network (PINN) is used to determine pressure fields from experimentally measured velocity data. PINN is a novel data assimilation method that simultaneously optimizes velocity and solves pressure by incorporating the Navier-Stokes equations into the loss function. The performance of the PINN method is compared with two traditional pressure reconstruction algorithms, and it is numerically assessed using different flow motions and experimental cases.

Summary: Ice nucleating particles (INPs) are a rare subset of particles that can have a significant impact on climate. Models need effective parameterizations to simulate the variability of INPs, with laboratory and field measurement-based parameterizations having their own advantages and disadvantages. Heterogeneous ice nucleation rate coefficients for ambient particles can be measured using a single-particle mass spectrometer.

Summary: This study investigates the effect of loading rate on earthquake nucleation and fault rupture through experiments. The findings show that the loading rate has a significant impact on the recurrence interval, shear stress drop, and peak friction of stick-slip events. Prior to dynamic rupture, a stable nucleation phase exists, and its length decreases with both the loading rate and normal stress.

Summary: We developed an evaluation system, termed Controllable volumetric prover (CVP), for assessing the responsiveness of flowmeters. The CVP system enables simultaneous measurement and control of transient flow rate, allowing for efficient evaluation of flowmeter performance. Analytical methods such as Lissajous curve plotting, cumulative error calculation, and frequency filtering are used to quantify the responsiveness. This study demonstrated the efficacy of the CVP test using an ultrasonic flowmeter as an example, showing its potential in evaluating frequency and amplitude dependence as well as hysteresis effects.

Summary: The study evaluated a workflow for characterizing capillary heterogeneities in complex rocks and found that the success of the workflow is primarily determined by the resolution of heterogeneous structures in X-ray imagery. The performance of the workflow systematically improved with increasing characteristic length scales of heterogeneities. The findings showed non-monotonic behavior in upscaled relative permeability due to isotropic heterogeneity in carbonate samples that initially increased and subsequently decreased with increasing flow rate.

Summary: The nucleation of bubbles in a stretched Lennard-Jones liquid between two flat smooth solid walls was investigated using molecular dynamics. The centers of bubbles are mainly located at a distance of (1.5-3) molecular diameters from the walls, with the nucleation rate near the walls being two orders of magnitude higher than in a homogeneous liquid. The liquid boiling-up in the presence of smooth wettable walls proceeds by the mechanism of homogeneous nucleation, regardless of the bubble formation location.

Summary: In developed countries, poor indoor air quality has a significant impact on human health. The burden of disease related to indoor air pollution leads to millions of premature deaths. CO2 is the most common indoor air pollutant, and its concentration can be higher indoors due to human activities. Despite ventilation efforts, controlling CO2 concentration below recommended levels is a challenge, with many indoor environments exceeding the threshold. This review explores the issues associated with poor indoor air quality and highlights the potential of indoor CO2 direct air capture to purify air and contribute to the circular economy.

Summary: This study focuses on phosphorus recovery as struvite from the liquid fraction of swine manure digestate at a high total solids concentration. A by-product of salt production (seawater bittern, SWB) was assessed as Mg source for the formation of struvite within a circular economy approach. The results showed that struvite obtained from the digestate can be used as a competitive alternative to conventional chemical phosphate fertilizers.

Summary: The article proposes a framework that extends the theory of nudges to all stages of the urban water cycle and to various decision-making levels, in order to address the challenges associated with the urban water cycle and achieve the UN Sustainable Development Goals. The framework integrates four main drivers, including the fourth water revolution, digitalization, decentralization, and climate change, which influence how different stakeholders approach the challenges posed by the urban water cycle. The proposed framework serves as a reference for policymakers to develop medium and long-term strategies and policies for improving the sustainability and resilience of the urban water cycle.

Summary: The recovery of nutrients from wastewater for agricultural fertilization is an interesting approach. In this study, wastewater recovered magnesium phosphate salts were used as draw solution in a forward osmosis system to extract water and produce a nutrient solution for hydroponic lettuce cultivation. The low solubility of the magnesium phosphate salts was overcome by acid dissolution using citric and nitric acids.

Summary: Recently, it has been suggested that Alcaligenes can convert ammonium into dinitrogen gas using a previously unknown pathway. This research found that Alcaligenes can simultaneously oxidize succinate and ammonium in the presence of a polarised electrode and without aeration. This indicates that the polarised electrode can support the metabolic functions of Alcaligenes.

Summary: The industrial adoption of microbial electrosynthesis (MES) is hindered by high overpotentials and inefficient cell designs. In this study, a mixed microbial consortium was adapted for acetate production from bicarbonate under saline conditions. The enriched communities were used as inoculum in three-chamber cells and achieved high acetate production rates with Coulombic efficiency. The experiment also demonstrated that connecting multiple cells in series can significantly increase the production rates.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
