Corrosion protection of aluminum by smart coatings containing layered double hydroxide (LDH) nanocontainers

In this study, the LDH containing a kind of green inhibitor (sodium molybdate) was synthesized and utilized in a poly-vinyl alcohol (PVA) base coating applied on the aluminum (5054 series) surface. After evaluating the LDH performance, the inhibitor release from the LDH crystals was examined by changing significant parameters like MII/MIII (the molar ratio of divalent ions into trivalent ions), pH, aging time and temperature. In order to find the kinetic release of intercalated inhibitor a prediction model was introduced in 3.5% NaCl solution. The model expressed that the pH as the processing parameter has special effect on the kinetic releasing of the inhibitor. It can enhance the amount of released inhibitor up to 6 times larger due to its effect on the LDH morphology and structure. Also MII/MIII has serious effect on the amount of intercalated inhibitor and the release rate. In fact, the ratio alteration can affect the amount of final released inhibitor by a factor of 2 and its interaction with the pH is noticeable. The whole mechanism of releasing was recognized as Fickian diffusion and the released data were well fitted with the Weibull model. Corrosion measurements show the mechanism activation of the synthesized smart coating and improvement of the corrosion properties (the polarization resistance has been enhanced more than 3 times) in compare with the regular coatings. More LDH in the coating network result in better resistance (39,250 Ω cm−1) t...

The objective of this study was the evaluation of Hawthorn and Rosemary methanol extracts as preventive treatment in alcoholic liver disease (ALD). ALD rat model was used to measure serum hepatic enzyme levels (AST, ALT, γ-GT and ACP), total bilirubin, liver glycogen, lipid peroxidation, total antioxidant capacity (TAC) and serum lipid profile (total cholesterol, triglycerides, LDL and HDL) as well as histopathological analysis in hepatic tissues was recorder. Phytotreatments showed preventive effect, decreasing AST, γ-GT, lipid peroxidation and bilirubin indictors while TAC and liver glycogen stores increase. ...

Discussion A recent systematic review of house fires in high-income countries found that the risk factors for unintentional house fire incidents included: more children under 5 years of age, more people in the home, more males in the home, adults who are not working, low-income, household smokers, non-privately owned housing, poor condition housing. Other risk factors are not having smoke detectors, but more importantly not having a working smoke detector. Risk factors for injuries or fatalities is similar to the the risk factors for incidents but also includes people who are vulnerable such as a disabled resident, someon...

Publication date: Available online 15 June 2019Source: MicronAuthor(s): M. Rusaczonek, B. Zapotoczny, M. Szymonski, J. KoniorAbstractElasticity of biological systems is considered to be an important property that might be related to functional or pathological changes. Therefore, careful study and detailed understanding of cell and tissue elasticity is crucial for correct description of their functioning. Atomic force microscopy (AFM) is a powerful technique, which allows for determination of the physical properties, such as elasticity, of soft-matter systems in nano-scale. An important step in AFM elasticity studies is a p...

Citrin deficiency is characterized by 1) neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD); 2) adaptation/compensation stage with unique food preference from childhood to adulthood; and 3) CTLN2. The treatment of NICCD aims to prevent the progression of cholestasis, and it i...

This study analyses out-of-home food purchases by food groups and food outlet types, and estimates socio-economic differences in these expenditure patterns. We used a nationally representative product-level dataset of expenditures (n=2,734,987) on foods and non-alcoholic beverages for out-of-home consumption for 9,704 respondents in Great Britain (June 2015-December 2017). Population weighted estimates of per capita weekly expenditures and shares of expenditure were derived for four outlet types and eight food groups. We used linear multi-level modelling to determine differences in expenditure patterns by socio-economic st...

Abstract Dopaminergic (DA) neurons are involved in many critical functions within the central nervous system (CNS), and dopamine neurotransmission impairment underlies a wide range of disorders from motor control deficiencies, such as Parkinson's disease (PD), to psychiatric disorders, such as alcoholism, drug addictions, bipolar disorders, schizophrenia and depression. Neural stem cell-based technology has potential to play an important role in developing efficacious biological and small molecule therapeutic products for disorders with dopamine dysregulation. Various methods of differentiating DA neuron...

CONCLUSIONS: Our intervention was effective, by significantly improving the participants' knowledge and by inducing significant behavioral changes. Improving the formulation of alcoholic hand rubs may be a key factor to encourage their use. Coexisting non-occupational risk behaviors are just as important in the prevention of CHE.
