Abstract

Artificial Intelligence (AI) approaches are increasingly being applied to more and more domains of Science, Engineering, Chemistry, and Industries to not only improve efficiencies and enhance productivity, but also enable new capabilities. The new opportunities range from automated molecule design and screening, properties prediction, gaining insights of chemical reactions, to computer-aided design, predictive maintenance of systems, robotics, and autonomous vehicles. This review focuses on the new applications of AI in manufacturing and healthcare. For the Manufacturing Industries, we focus on AI and algorithms for (1) Battery, (2) Flow Chemistry, (3) Additive Manufacturing, (4) Sensors, and (5) Machine Vision. For Healthcare applications, we focus on: (1) Medical Vision (2) Diagnosis, (3) Protein Design, and (4) Drug Discovery. In the end, related topics are discussed, including physics integrated machine learning, model explainability, security, and governance during model deployment.

Abstract

Ion complexes hold the key for various energy transfer and communication systems in nature and industries. Achieving controllable mechanical and electrical properties in these complex systems is highly desirable but remains challenging. In this work, we propose the use of amphiphilic molecules to mediate salt crystallization. The resultant ionic interfaces can be tunable through reduced surface tensions of crystal facets, an additional intermolecular modifier, and the diffusion-limited crystallization during controlled solvent evaporation. Specifically, we utilized the ionic surfactant Sodium Lauryl sulfoacetate (SLSA) to mediate the crystallization of sodium chloride. Citric acid (CA) was adopted as a hydrogen-bond modifier. Systems mediated by SLSA exhibited the highest capacitance, and a significant enhancement of capacitance was also observed in systems with both SLSA and CA. The substantially increased capacitance of these ionic complexes can be attributed to changes in interfacial and crystalline grain structures. Transmission electron microscopy (TEM), optical microscopy (OM), and Finite Element Analysis (FEA) were used to study the effects of surfactant molecules in these ionic complexes. Understanding the role of ionic complexation in defining the thermodynamic and kinetic process of the crystallization process will contribute to better optimization in nucleation and scalability of organic and inorganic crystal production., Comment: 23 pages, 8 figures

Abstract

In this article, the rheological behavior of polyvinyl chloride (PVC)-grafting- diallyl phthalate (DAP) was evaluated with melt flow index measurement and the small amplitude frequency sweep experiments. Frequency sweep tests using a parallel plate rheometer were conducted at 190[degrees]C to evaluate the rheological properties of PVC-g-DAP copolymers with different grafting ratios of DAP (0, 3, 5, 8, and 10%). Frequency sweep data were analyzed in terms of Cole-Cole plot, Han plot, and VGP plot. The results suggested that grafting DAP onto PVC reduced the viscosity and melt elasticity and greatly improved processability of the polymer. The mechanism of the grafting was interpreted as its benefits to promote fusion and gelation level of PVC, which was further confirmed through the SEM study. KEYWORDS grafting, PVC-g-DAP, process property, rheological property, 1 | INTRODUCTION Polyvinyl chloride (PVC), the second largest universal plastic in the world, is an interesting material that has high strength, high modulus, high corrosion resistance, and unique self-extinguish.

Abstract

Patients with inflammatory bowel disease (IBD) often have the condition of malnutrition, which can be presented as sarcopenia, micronutrient deficiencies, etc. Trace elements (magnesium, calcium, iron, copper, zinc, plumbum and manganese) belonging to micronutrients, are greatly vital for the assessment of nutritional status in humans. Trace element deficiencies are also the main manifestation of malnutrition. Calcium (Ca) has been proved to play an important part in maintaining body homeostasis and regulating cellular function. However, there are still a lack of studies on the association between malnutrition and Ca deficiency in IBD. This research aimed to investigate the role of Ca for malnutrition in IBD patients. We prospectively collected blood samples from 149 patients and utilized inductively coupled plasma mass spectrometry to examine their venous serum trace element concentrations. Logistic regression analyses were used to investigate the association between Ca and malnutrition. Receiver operating characteristic (ROC) curves were generated to calculate the cutoffs for determination of Ca deficiency. Except Ca, the concentrations of the other six trace elements presented no statistical significance between non-malnutrition and malnutrition group. In comparison with the non-malnutrition group, the serum concentration of Ca decreased in the malnutrition group (89.36 vs 87.03 mg/L, p = 0.023). With regard to ROC curve, Ca < 87.21 mg/L showed the best discriminative capability with an area of 0.624 (95% CI: 0.520, 0.727, p = 0.023). Multivariate analyses demonstrated that Ca < 87.21 mg/L (OR = 3.393, 95% CI: 1.524, 7.554, p = 0.003) and age (OR = 0.958, 95% CI: 0.926, 0.990, p = 0.011) were associated with malnutrition risk. Serum Ca levels were significantly lower in the malnutrition group than those in the non-malnutrition group among UC patients, those with severe disease state or the female group. In patients with IBD, Ca deficiency is an independent factor for high malnutrition risk. [ABSTRACT FROM AUTHOR]
