Abstract:
Symmetry-adapted bases in quantum chemistry and bases adapted to quantum information share a common characteristics: both of them are constructed from subspaces of the representation space of the group SO(3) or its double group (i.e., spinor group) SU(2). We exploit this fact for generating spin bases of relevance for quantum systems with cyclic symmetry and equally well for quantum information and quantum computation. Our approach is based on the use of generalized Pauli matrices arising from a polar decomposition of SU(2). This approach leads to a complete solution for the construction of mutually unbiased bases in the case where the dimension d of the considered Hilbert subspace is a prime number. We also give the starting point for studying the case where d is the power of a prime number. A connection of this work to the unitary group U(d) and the Pauli group is briefly underlined.

Abstract:
This article explored diversity and hybridity in the third space as a teaching resource. Students bring to the classroom or third space their diverse sociocultural issues, knowledge levels of chemistry, and socioeconomic status. Educators also bring to the third space their university knowledge and culture. Hence, a classroom or third space is a hybrid. The intersection of the students’ activity systems and educators’ activity systems created a third space. Activity systems are social practices that include the norms, values, divisions of labour, and community goals. The study intended to explore the negotiations by chemistry educators and first-year students in teaching-learning of acids-bases reactions. It is a topic that most students experience challenges from secondary school to graduate level. Acids-bases are one of the threshold concepts. Qualitative research was employed in the study. Data were collected through classroom observations. A thematic approach was employed to analyse data. Five chemistry educators and their classes were purposely sampled. Cultural-Historical Activity Theory (CHAT) was employed to unpack group dynamics in a Zambian university. Interactions in the learning spaces generated constraints, tensions, diversity, and affordances for both educators and students. The findings suggest that hybridity may be a resource in teaching acids-bases threshold concepts. Educators should understand students’ knowledge and cultural diversities. Researchers can investigate how students’ different acids-bases knowledge levels can promote success in chemistry.

Abstract:
Non classical methods (water based reaction, microwave and grindstone chemistry) were used for the preparation of Schiff bases from 3-chloro-4-fluoro aniline and several benzaldehydes. The key raw materials were allowed to react in water, under microwave irradiation and grindstone. These methodologies constitute an energy-efficient and environmentally benign greener chemistry version of the classical condensation reactions for Schiff bases formation.

A new method has been developed for the synthesis of novel Schiff bases containg anthraquinone moiety using dodeca-Tungstosilicic acid/P2O5 under solvent free conditions at room temperature. The reaction was completed in 1-3 minutes with excellent yields. This method was found to be more efficient, easy and hazardous free for the synthesis of azomethines. The development of these type of methadologies in synthetic chemistry may contribute to green chemistry. The structures of synthesized novel Schiff bases was elucidated using 1H-NMR, 13C-NMR, LCMS, FTIR and CHN analysis.

Abstract:
Even 155 years after their first synthesis, Schiff bases continue to surprise inorganic chemists. Schiff-base ligands have played a major role in the development of modern coordination chemistry because of their relevance to a number of interdisciplinary research fields. The chemistry, properties and applications of transition metal and lanthanoid complexes with Schiff-base ligands are now quite mature. On the contrary, the coordination chemistry of Schiff bases with actinoid (5f-metal) ions is an emerging area, and impressive research discoveries have appeared in the last 10 years or so. The chemistry of actinoid ions continues to attract the intense interest of many inorganic groups around the world. Important scientific challenges are the understanding the basic chemistry associated with handling and recycling of nuclear materials; investigating the redox properties of these elements and the formation of complexes with unusual metal oxidation states; discovering materials for the recovery of trans-{UVIO2}2+ from the oceans; elucidating and manipulating actinoid-element multiple bonds; discovering methods to carry out multi-electron reactions; and improving the 5f-metal ions’ potential for activation of small molecules. The study of 5f-metal complexes with Schiff-base ligands is a currently “hot” topic for a variety of reasons, including issues of synthetic inorganic chemistry, metalosupramolecular chemistry, homogeneous catalysis, separation strategies for nuclear fuel processing and nuclear waste management, bioinorganic and environmental chemistry, materials chemistry and theoretical chemistry. This almost-comprehensive review, covers aspects of synthetic chemistry, reactivity and the properties of dinuclear and oligonuclear actinoid complexes based on Schiff-base ligands. Our work focuses on the significant advances that have occurred since 2000, with special attention on recent developments. The review is divided into eight sections (chapters). After an introductory section describing the organization of the scientific information, Sections 2 and 3 deal with general information about Schiff bases and their coordination chemistry, and the chemistry of actinoids, respectively. Section 4 highlights the relevance of Schiff bases to actinoid chemistry. Sections 5–7 are the “main menu” of the scientific meal of this review. The discussion is arranged according the actinoid (only for Np, Th and U are Schiff-base complexes known). Sections 5 and 7 are further arranged into parts according to the oxidation states of Np and U, respectively, because the coordination chemistry of these metals is very much dependent on their oxidation state. In Section 8, some concluding comments are presented and a brief prognosis for the future is attempted.

Abstract:
The Michael addition reaction was revisited with a full focus on sustainability combined with efficiency, using mechanochemistry in mild conditions. First, the synthesis of cyclopentenone derivatives was chosen as a model reaction to find optimal conditions in mechanochemistry while using classical but weak bases. The reaction was efficient (84–95% yields), fast (2–6 h), solvent free, and required 0.1 equivalent of base. Aiming to reach greener conditions, classical bases were then replaced using new bio-sourced bases, called Eco-bases, that were easily prepared from plants and led to heterogeneous catalysts. The composition and structure of Eco-bases were characterized by MP-AES, XRPD, EBSD/EDS, HRTEM/EDX and ion chromatography. Interestingly, a high ratio of potassium was observed with the presence of K2Ca(CO3)2 for the most effective Eco-base. The new Eco-bases were used for the mechanical-assisted construction of functionalized alkenone derivatives. The versatility of the method has been successfully applied with good to excellent yields to different Michael donors and acceptors. Eco-bases were recycled and reused four times with the same performances. Combining Eco-bases and mechanochemistry in Michael addition reactions allowed reaching a maximum degree of sustainability (efficient, rapid, low catalyst loading, solvent-free reactions with bio-sourced catalysts) and participating in the development of mechanochemistry in sustainable chemistry.

Abstract:
The dissemination of scientific knowledge has enormous transformative potential. As a result, a nation's progress and growth can't get off the ground without a solid foundation in scientific literacy. From this perspective, the education of science is crucial to cultivating a scientific worldview and boosting students' scientific knowledge. The motivation for this study stems from researchers' previous observations of secondary school students' conceptual difficulties in acid-base chemistry. The study used a descriptive, quantitative research approach to investigate common misconceptions about acid-base chemistry held by high school pupils. A special test instrument labelled as test designed to measure the conceptual difficulties in acid-base chemistry (TCDAB) was developed to measure the conceptual difficulties of secondary school students in Acid-Base chemistry. The Punjab Text Book Board, Lahore, version January 2020, 10th chapter Chemistry Text Book was used as a reference for the creation of the test (TCDAB). A table of the specification was used and was delimited to the first three levels of the cognitive domain of Bloom’s taxonomy. TCDAB has been validated by well-known chemists and educators. Test re-tests method was used to determine the reliability and the correlation coefficient (r) was 0.92. The internal consistency of the instrument was also evaluated using SPSS, and the resulting Cronbach alpha coefficient was 0.83. All the students studying chemistry in public secondary school of the district Bahawalnagar of the Punjab, Pakistan were population of this study (Dist. BWN consist of five tehsils which having total 250 schools). To conduct the survey of this study, a sample of 500 students from twenty (20) secondary schools, four (4) secondary schools (2 boys and 2 girls) from each five tehsils was selected by using the convenient sampling technique due to covid-19 in district Bahawalnagar city. The results of the analysis of TCDAB indicated that 60% concept-based items in acid-base chemistry were difficult like Arrhenius concept, Lowry Bronsted concept and Lewis Concepts, amphoteric compounds, conjugate acids and bases, chemical properties of acids and bases, concentration of acid base chemistry, strength of acid base chemistry, Uses of acids and bases, PH scale, and indicators.

Abstract:
: The enhanced applications of Schiff bases metal complexes of amino acid derivatives have captured the attention of researchers for the synthesis of leucine derivatives of Schiff bases metal complexes. Amino acids are considered to be essential part of food supplements as well as derivatives of Schiff bases in coordination chemistry due to their donor ability. The leucine derivatives Schiff bases ligand have been synthesized by condensation reaction between amine of leucine with aldehyde or ketone bearing molecules attached with them. These complexes were characterized by different spectroscopic tools in order to confirm their structural geometries. The structural geometries are considered to be very important in order to improve the antimicrobial potential of leucine derivative metal complexes. By taking into account the antimicrobial potential of titled compounds, a comprehensive review of leucine derivatives of Schiff bases metal complexes has been compiled.
