Progress in Chemistry Studies for Students of Industrial Pharmacy Speciality with Different Learning Styles

The paper goal was to analyse the actual learning preferences of students in the speciality "Industrial Pharmacy" and find correlations between the learning styles and academic success in the study of chemistry. The Indices of Learning Styles by Felder-Soloman’s model were investigated for 1st to 5th-year students. The preferred learning styles do not change in the course of 4-years undergraduate studies and are described by the propensity to active (65-79% out of all students), sensitive (82-92%), visual (75-81%) and sequential (64-73%) manners of study. Master students are more susceptible to the reflective (43% of graduates vs 29% of undergraduates), intuitive (29% vs 12%) and verbal styles (43% vs 23%). No significant changes take place in the sequential-global dimension. The change in the general profile of a group of master students occurs at a stage of additional selection of graduates when they enter their master’s course. Progress in studies of eight chemistry and chemical technology disciplines was compared for students with typical and non-typical profiles. The higher the number of typical styles in learning preferences, the more definite distinction is observed in the academic performance. Students with typical learning profiles usually demonstrate better academic performance in studying chemical disciplines, but the difference becomes statistically significant with increasing the number of typical styles in learning preferences.

Synthesis and CYP24A1-Dependent Metabolism of 23-Fluorinated Vitamin D3 Analogues

Two novel 23-fluorinated 25-hydroxyvitamin D3 analogues were synthesized using Inhoffen–Lythgoe diol as a precursor of the CD-ring, efficiently. Introduction of the C23 fluoro group was achieved by the deoxy-fluorination reaction using N,N-diethylaminosulfur trifluoride or 2-pyridinesulfonyl fluoride (PyFluor). Kinetic studies on the CYP24A1-dependent metabolism of these two analogues revealed that (23S)-23-fluoro-25-hydroxyvitamin D3 was more resistant to CYP24A1-dependent metabolism than its 23R isomer.
REMOVAL OF CHROMIUM(VI) FROM WASTEWATER USING CITRIC ACID MODIFIED SUGARCANE BAGASSE

Toxic metals have been excessively released into the environment due to rapid industrialization and have created a major global concern. Cadmium, zinc, copper, nickel, lead, mercury and chromium are often detected in industrial wastewaters. Various methods are available in literature although some of them facing difficulties to be applied. The present study, bagasse from sugarcane industry was used to remove chromium(VI) ions from wastewater. This study presents the adsorption behavior of hexavalent chromium from wastewater using low cost adsorbent modified sugarcane bagasse with citric acid (SCB). The effect of the initial concentration of chromium(VI), biosorbent dosage, temperature, contact time, and pH were studied. It was found that maximum % removal of chromium(VI) is obtained 92.19 % at pH 1.2 and contact time 40 min. The removal is decreased with increase in concentration and also pH. The maximum biosorption capacities q e of chromium(VI) ions by SCB was 13.5 mg g -1 . This work proved that treated bagasse can be used as an efficient adsorbent material for removal of heavy metals from wastewater such as chromium(VI).
Architectural and anatomical responses of maize roots to agronomic practices in a semi-arid environment

Root architecture and anatomy are important determinants of nitrogen (N) and water acquisition, but they are also environmentally plastic to adapt to N and water availability. Therefore, understanding the relationship between root traits and environmental factors is essential for improving N and water acquisition. A field experiment was conducted in the semi‐arid region of the Loess Plateau in northwestern China to quantify the architectural and anatomical root traits of maize (Zea mays L.) in response to plastic film mulching and N fertilization. We compared four treatments: non‐mulching with and without N supply as well as plastic film mulching with and without N supply. Variation existed for all root architecture and anatomy traits within maize root crowns. Crown and brace root angles to the soil line decreased in response to film mulching and N fertilization. Crown roots under plastic film mulching showed a significantly decreased distance to branching, reduced lateral root length, and overall increased root diameter. Similarly, N application significantly decreased the distance to branching, yet induced more compact and denser crown roots, and increased the root diameter. Brace roots exhibited an increased distance to branching, greater lateral root length and density, as well as a larger root diameter in response to plastic film mulching and N fertilization. Additionally, the accumulated number of nodal roots increased greatly under plastic film mulching and N treatments. At the anatomical level, N application reduced the proportion of the root cortical aerenchyma area. In contrast, aerenchyma area, cortex cell size, and late metaxylem vessel diameter were increased as a result of plastic film mulching. These results demonstrate root architectural and anatomical traits respond to mulching practices and N fertilization.

Dunite in Agriculture: Physiological Changes, Nutritional Status and Soybean Yield

ABSTRACT Brazil is an importer of fertilizers and the use of alternative sources is increasing in agriculture. The objective of this study was to evaluate the effect of Dunite rates on magnesium (Mg), silicium (Si), reducing sugars, sucrose and foliar starch, soil chemical attributes and soybean yield [Glycine max (L.) Merril] in two soil types. The treatments consisted in the five Dunite rates (0, 42, 208, 542, and 1542 mg kg−1) in a clayey soil, and five Dunite rates (0, 150, 238, 411, and 933 mg kg−1) in a sandy soil. In both crops and soils, the Mg and Si contents, reducing sugars and foliar glucose, as well as pH, Mg and Si of the soil, and yield components showed a positive response due to the increase of input rates. The Mg nutrition provides lower foliar starch levels, consequently, the best partition of metabolites to plant leads to better development, filling and yield of soybeans.

A High‐Performance Monolithic Solid‐State Sodium Battery with Ca2+ Doped Na3Zr2Si2PO12 Electrolyte

Solid‐state sodium batteries (SSSBs) are promising electrochemical energy storage devices due to their high energy density, high safety, and abundant resource of sodium. However, low conductivity of solid electrolyte as well as high interfacial resistance between electrolyte and electrodes are two main challenges for practical application. To address these issues, pure phase Na3Zr2Si2PO12 (NZSP) materials with Ca2+ substitution for Zr4+ are synthesized by a sol‐gel method. It shows a high ionic conductivity of more than 10−3 S cm−1 at 25 °C. Moreover, a robust SSSB is developed by integrating sodium metal anodes into NZSP‐type monolithic architecture, forming a 3D electronic and ionic conducting network. The interfacial resistance is remarkably reduced and the monolithic symmetric cell displays stable sodium platting/striping cycles with low polarization for over 600 h. Furthermore, by combining sodium metal anode with Na3V2(PO4)3 cathode, an SSSB is demonstrated with high rate capability and excellent cyclability. After 450 cycles, the capacity of the cell is still kept at 94.9 mAh g−1 at 1 C. This unique design of monolithic electrolyte architecture provides a promising strategy toward realizing high‐performance SSSBs.
Future trends in stratosphere-to-troposphere transport in CCMI models

Abstract. One of the key questions in the air quality and climate sciences is how tropospheric ozone concentrations will change in the future. This will depend on two factors: changes in stratosphere-to-troposphere transport (STT) and changes in tropospheric chemistry. Here we aim to identify robust changes in STT using simulations from the Chemistry Climate Model Initiative (CCMI) under a common climate change scenario (RCP6.0). We use two idealized stratospheric tracers to isolate changes in transport: stratospheric ozone (O3S), which is exactly like ozone but has no chemical sources in the troposphere, and st80, a passive tracer with fixed volume mixing ratio in the stratosphere. We find a robust increase in the tropospheric columns of these two tracers across the models. In particular, stratospheric ozone in the troposphere is projected to increase 10 %–16 % by the end of the 21st century in the RCP6.0 scenario. Future STT is enhanced in the subtropics due to the strengthening of the shallow branch of the Brewer–Dobson circulation (BDC) in the lower stratosphere and of the upper part of the Hadley cell in the upper troposphere. The acceleration of the deep branch of the BDC in the Northern Hemisphere (NH) and changes in eddy transport contribute to increased STT at high latitudes. These STT trends are caused by greenhouse gas (GHG) increases, while phasing out of ozone-depleting substances (ODS) does not lead to robust transport changes. Nevertheless, the decline of ODS increases the reservoir of ozone in the lower stratosphere, which results in enhanced STT of O3S at middle and high latitudes. A higher emission scenario (RCP8.5) produces stronger STT trends, with increases in tropospheric column O3S more than 3 times larger than those in the RCP6.0 scenario by the end of the 21st century.
Styrene-butadiene branched star-shaped asphalt modifiers: Synthesis and mechanical characterization

Abstract The synthesis and the corresponding characterization of styrene-butadiene (SB), branched, star-shaped copolymers was investigated as part of a research project on asphalt modification using polymers with precise molecular structures. The method of anionic polymerization was followed to prepare samples of block copolymers of SB, a synthesis method that controls chain-architecture, molecular weight distribution, monomer distribution, and the average molecular weight. The research studies are the synthesis of block copolymers including linear, three- and four-arms constructs, depending on the coupling agent used. The techniques of nuclear magnetic resonance (1NMR), differential scanning calorimetry (DSC), gel permeation chromatography (GPC), and rheology were carried out to characterize the copolymers. From the results of the 1NMR, DSC, and GPC analyses, all star-shaped copolymers investigated showed a similar block copolymer composition. Furthermore, the rheological behavior of one of the synthesized star-shaped copolymers was nearly the same as a four-branched commercial copolymer. Rheologically, the four-arm block copolymer sample had the largest storage modulus (G′) among the branched copolymers synthetized, indicating that such architecture produces a highly structured material. In regard to polymer-modified asphalt formulations, the three-branched copolymer architecture yielded better elastic behavior than the four-branch version. In summary, the findings of this investigation provide new insight about a polymer system that may offer advantages in industrial asphalt paving applications.
AQUEOUS LEAF EXTRACT OF ZIZIPHUS MAURITIANA IS POTENT ON CARBON TETRACHLORIDE-INDUCED LIVER DAMAGE IN ALBINO RATS

Globally and locally there is an increase in burden of liver diseases arising from toxins, infectious and non-infectious conditions. This research work was aimed at studying the effects of aqueous leaf extract of Ziziphus mauritiana on Carbon Tetrachloride-induced liver damage in albino rats in comparison with currently used drug Livolin. Liver damage was induced by intramuscular injection of 120 mg/kg by weight of CCl 4 . The effects of aqueous leaves extract of Z. mauritiana were determined in groups of liver toxicity model rats. Different groups of rats (total of 36 rats) were administered with three different doses of aqueous leaves extract of Z. mauritiana (50 mg/kg, 100 mg/kg and 150 mg/kg), with assessment of liver functions indices at intervals of two and four weeks. The allocation was as follows: control group (6 rats), test-control (6 rats), 50 mg/Kg extract dose (6 rats), 100 mg/Kg extract dose (6 rats), 150 mg/kg dose (6 rats) and Livolin group (6 rats). Dose and time-dependent responses were found in the normalisation of the liver functions indices and histological, with the best performing extract (150 mg/kg) been less efficacious than Livolin in liver damage. The findings of this study shows that aqueous leaf extract of Z. mauritiana has phytochemical components that can potentially be useful in treating liver damage, with effects comparable to currently used pharmaceutical drugs like Livolin.

Instructional misconceptions of prospective chemistry teachers in chemical bonding

This paper is a report of an action research which attempts to detect and correct various misconceptions in chemical bonding retained by some pre-service chemistry teachers who were in their third and fourth year in the university. At systematic and elaborate instructional sessions, questioning approach, micro teaching, and structured essay test were employed to detect misconceptions while concept mapping blended with cooperative learning was used to correct the identified misconceptions. 64 pre-service chemistry teachers (which have gone on teaching practice in some Nigerian secondary schools) from a state university participated in the study. Similar chemical concepts were identified by over 90% of the pre-service teachers as topics often being regarded as both difficult to understand by learners and teach by graduate teachers but sources of misconceptions were highlighted in only one major concept among those listed, namely; chemical bonding. The study revealed a high level of varied chemical misconceptions among the pre-service teachers which did not alter significantly through their four years of training. However, during groups’ interaction and with the aid of concept maps, some of the misconceptions were removed as they were enabled to apply their knowledge of concepts and their interrelations, as well as formulate appropriate theoretical explanations for the observed changes they viewed. Key words: Misconceptions, prospective teachers, concept maps, difficult chemical concepts.
Spectral Characteristics of 5-Hydroxymethylfurfural as Related Substance in Medicinal Products Containing Glucose

Objectives: To study 5-hydroxymethylfurfural (5-HMF) spectral characteristics aiming at their future application in analytical procedures and their validation for the determination of 5-HMF in liquid products containing glucose after sterilization. Method: Direct spectrophotometric method for the determination of 5-HMF using the molar absorption coefficient at the absorption maximum (284 nm). Results and discussion: aqueous 5-HMF solutions have strong absorption in the ultraviolet range below 310 nm and give two absorption maxima at wavelengths of 229–230 nm and 284 nm. An excellent linear relationship between absorbance and 5-HMF concentration was observed in the concentration range of 2.0–10.0 mg/l. The linear dependence passes through the origin. The molar absorption coefficients of 5-HMF were determined and found to be 3007 mol−1•L•cm−1at 229–230 nm and 16070 mol−1•L•cm−1at 284 nm. The use of the molar absorption coefficient of 5-HMF stated in the Pharmacopeia of the United States of America for determining 5-HMF in polydextrose (16830 mol−1·L·cm−1at 283 nm) gives recovery results for model solutions of reference substance of 5-HMF that are acceptable from the point of view of the requirements of the State Pharmacopeia of Ukraine for methods of quantitative determination of impurities. However, other values of the molar absorption coefficient (17000 and 22700 mol−1•L•cm−1) given in the scientific publications are unsuitable for the quantitative determination of 5-HMF as an impurity in medicinal products. Conclusion: The molar absorption coefficient (16830 mol−1•L•cm−1at 284 nm) may be used to quantify 5-HMF as an impurity in medicinal products containing glucose. For a specific medicinal product, a full validation of the analytical procedure of the 5-HMF determination is required taking into account the composition of this product.
