- Description: [From Introduction] Message from Ujala: The last three months have been an exciting time for me at the Rhodes University Library (RUL) as it coincides with my first 100 days as the Director. It’s been a time for observations, questions, conversations, reviews, meetings, gaining trust, challenging assumptions and old habits, and taking ownership with the intention of facilitating change and innovation for a redefined future. After all of this, I must admit that the future looks extremely positive. An invitation to speak at the 11th South African Online Information Meeting (SAOIM) on 06 June 2012 on the topic “Change and Innovation: the need to push the limits” gave me pause for thought regarding innovation and organizational development. While there is a tendency to link innovation to technology, it may be used to implement change at every level of an organization. Change refers to altering one’s approach or attitude; a process which enables transformation, becoming different or doing things differently. Peter Drucker defines innovation as “change that creates a new dimension of performance.” Therefore an effective organization must be prepared to grasp the opportunities, alongside the threats, by responding to the challenge of change to continue adding value to its defined audience. An innovative organization focuses on the following four significant areas: - Alignment of internal strategies to corporate/institutional goals and strategies - People, skills and roles - Defined workflows or processes - Cultural engagement and support Keeping the above in mind, the following activities were held towards redefining the organization’s purpose and culture, and identifying the focus areas for 2013-2015: Review of the Faculty Library model on May 03 2012 with all the Principal Faculty Librarians. The following questions were addressed: - What are we doing well? - What are we not doing well? Why not? - How could we do things differently? - What are the burning issues critical for success or failure? - How well are we positioned for the future? 2-day strategic planning session on 14-15 June 2012 which was facilitated by Dr Noel Pearse of the Rhodes Business School. The context was set by Dr Sizwe Mabizela, the Acting Vice-Chancellor and the Dr Peter Clayton, DVC: Research who focused on the Rhodes priorities and the research agenda respectively. Presentations on Open Scholarship; Mobile Technologies; Library Leadership; Changing User Needs and Library as Space were made by staff and the World Café concept was used to encourage open discussions and exchange of ideas among staff in teams and across levels. The most positive and encouraging outcome hereof is that various task teams which include every member of staff have taken the responsibility of developing the eStrategy and the strategies relating to Marketing & Communications, Staff Development, User Services and Infrastructure, as well as the Purpose Statement (Vision, Mission and Values) and the Organisational Culture. This is indeed an innovative way of the staff taking ownership of the future of the organization. I believe that the greatest asset of an organization is its human capital and RUL is fortunate to have a corps of staff that is representative of different skills, expertise and varying experience. Collectively we can define the conditions for successful innovation by enhancing existing strengths; committing to change; focusing on specific needs; innovating for the present which will have long-term impact; and changing our behaviours and processes. This gives us the opportunity to: - demonstrate our value to the University management - take the lead in being strategic and inculcate the “One organization, many leaders” mindset - focus on exceptional user experiences - use technology as an enabler - redefine our role through collaboration and embedded librarianship Jean Sykes (Chief Librarian and Information Services Director: London School of Economics) is of the opinion that “Librarians are very well-placed to make a difference and secure an enviable reputation for our profession if we continue to watch, listen, think, analyse, collaborate, share, test and try and if we deploy real leadership skills, displaying a genuine willingness to keep reinventing ourselves and our old skills to match the changing environment we find ourselves in at any stage.” I agree!

Palaeoclimatic and archaeological implications of organic-rich sediments at Tiffindell Ski Resort, near Rhodes, Eastern Cape Province, South Africa

- Description: Analyses of organic-rich deposits from Tiffindell Ski Resort indicates that organic accumulation began somewhat before 4720 BP. This correlates well with the moister conditions known to have existed in the north eastern uplands of Eastern Cape Province (and in upland eastern Lesotho) in the later as compared with the earlier part of the Holocene. Palynological analyses of sediments dating from somewhat before 2790 BP to the present suggests that only limited environmental changes occurred in the pollen spectra. The wettest conditions apparently existed around 2700 BP, probably correlating with an increase in human occupation in the Eastern Cape (Southern) Drakensberg following the possible abandonment of that area during the dry phase(s) of preceding millennia.

- Description: The reaction of Zn(OAc)2 and C6H5COOH or 3,5-NO2-C6H3COOH with 3-ferrocenylpyrazolyl-methylenepyridine (L1), 3-ferrocenyl-5-methylpyrazolyl-methylenepyridine (L2), 3-ferrocenylpyrazolyl-ethylamine (L3) and 3-ferrocenyl-5-pyrazolyl-ethylamine (L4) afford the corresponding complexes [Zn(C6H5COO)2(L1)] (1), [Zn(C6H5COO)2(L2)] (2), [Zn(3,5-NO2-C6H3COO)2(L1)] (3), [Zn(3,5-NO2-C6H3COO)2(L2)] (4), [Zn(C6H5COO)2(L3)] (5), [Zn(C6H5COO)2(L4)] (6), [Zn(3,5-NO2-C6H3COO)2(L3)] (7) and [Zn(3,5-NO2-C6H3COO)2(L4)] (8). These complexes behave as catalysts for the ring opening polymerization of ɛ-caprolactone to produce polymers with molecular weight that range from 1480 to 7080 g mol−1 and exhibited moderate to broad PDIs. Evidence of these complexes acting as catalysts was obtained from both the polymerization data and kinetic studies. The polymerization data show that variation of the [CL]/[C] from 100 to 800 produced PCL with relatively the same molecular weight indicative of a catalyst behavior. The appearance of induction period in kinetic plots strengthens the fact that these complexes are catalysts rather than initiators. MALDI-TOF MS and 1H NMR data show di-hydroxy end groups, which support the coordination mechanism rather than insertion mechanism. To understand the broad PDIs obtained for some of the polymer, the electronic properties of the zinc complexes were investigated using cyclic voltammetry. The results show that the zinc complexes containing amine based ligands are highly electrophilic therefore making them unstable, hence the broad PDIs observed for zinc complexes containing amine based ligands. Among the eight complexes investigated, complex 7 is the most active catalyst with kp value of 1.18 × 10−7 h−1 mol−1 at 110 °C. , Original publication is available at http://dx.doi.org/10.1016/j.poly.2015.02.007

- Description: Nanocomposites containing CdSe quantum dots, tetra(4-(4,6-diaminopyrimidin-2-ylthio) phthalocyaninatocobalt(II)) (CoPyPc) and reduced graphene nanosheets (rGNS) were devoloped and used for the modification of a glassy carbon electrode. Characterization of the nanocomposites was done by transmission electron microscopy (TEM) and X-ray diffraction (XRD) analyses. Cyclic voltammetry (CV) was used for electrochemical characterization of the prepared nanocomposite for oxygen reduction reaction. The oxygen reduction activity for rGNS/CdSe-CoPyPc nanocomposite was found to be superior over the individual nanomaterials in this study. The activity of the nanocomposite towards oxygen reduction was also tested for tolerance to methanol crossover effect using chronoamperometry (CA) and electrochemical impedance spectroscopy (EIS) studies. , Original publication is available at http://dx.doi.org/10.1002/elan.201400372

- Description: Au and Pd nanoparticles were individually or together electrodeposited on top of polymerized cobalt tetraaminophthalocyanine (poly-CoTAPc). When Pd and Au nanoparticles are co-deposited together, the electrode is denoted as Au–Pd (co-deposited)/poly-CoTAPc-GCE. X-ray photoelectron spectroscopy (XPS) was used to show the successful deposition of AuNPs, PdNPs and Au–Pd (co-deposited). The scanning electrochemical microscopy showed that Au–Pd (co-deposited)/poly-CoTAPc-GCE (with current range of 9.5–13.5 μA) was more conducting than Au–Pd (co-deposited)-GCE (with current range of 8–12 μA). Electrochemical impedance spectroscopy (EIS) showed that there was less resistance to charge transfer for Au–Pd (co-deposited)/poly-CoTAPc-GCE compared to the rest of the electrodes. Au–Pd (co-deposited)/poly-CoTAPc-GCE showed the best activity for the electrooxidation of hydrazine in terms of limit of detection (0.5 μM), hence shows promise as an electrocatalyst for electrooxidation of hydrazine. , Original publication is available at http://dx.doi.org/10.1016/j.jcis.2014.10.056

- Description: In this work, tetrakis(5-hexyn-oxy)Fe(II) phthalocyanine was synthesised in order to perform a click reaction between the terminal alkyne groups and an azide group on a glassy carbon electrode (GCE) surface. An azide group was formed on the electrode surface following electrografting using 4-azidobenzene diazonium tetrafluoroborate by electrochemical reduction. The Cu(I) catalyzed alkyne-azide Huisgen cycloaddition reaction was then employed in order to react the terminal alkyne groups on the phthalocyanine with the azide groups on the GCE surface. The modified electrode was employed to catalyse the oxidation of hydrazine. The electrode showed good electrocatalytic ability towards the detection of hydrazine with a sensitivity of 15.38 µA mM−1 and a limit of detection of 1.09 µM. , Original publication is available at http://dx.doi.org/10.1002/elan.201500212
