Wir stellen die Biokonjugation von Polymeren vor, die durch RAFT‐Polymerisation mittels Hetero‐Diels‐Alder‐Cycloaddition durch ihren inhärenten terminalen Thiocarbonylthiorest mit einem dienmodifizierten Modellprotein synthetisiert wurden und keine spezifische funktionelle Endgruppe tragen. Die quantitative Konjugation erfolgt im Verlauf einiger Stunden bei Raumtemperatur und nahezu neutralem pH‐Wert und in Abwesenheit jeglichen Katalysators. Unsere Technologieplattform liefert thermoresponsive Biokonjugate, deren Aggregation allein durch die Polymerketten gesteuert wird.

This study evaluates the pattern of energy usage at the twenty-eight residences of the University of Johannesburg during the 2016 academic year. The study investigates the trend of energy consumption based on the total energy usage per residence in terms of the number of students at each of the residences on a monthly and daily basis. The data employed in this study was collected over a period of eleven months which is the overall effective academic calendar. The results obtained showed a contrast between the total energy usage per residence and energy usage per student. Sophia town residence recorded the highest total annual energy usage of 1547937.92 kWh while Takalani residence recorded the least which was 101863.73 kWh of all the residences considered in this study. However, when energy consumption was measured as a function of number of students in each residence, Gauta residence recorded the highest monthly energy usage per student (5165.17 kWh), followed by YMCA (4643.84 kWh) while the least monthly energy usage of 581.09 kWh was recorded in Maqhawe residence. Similarly, results obtained from the study on daily energy usage per student in the last five months of the 2016 academic year showed YMCA residence (20.34 kWh) and Lebone (16.42 kWh) as the two residences with the highest daily energy usage per student respectively. However, the energy usage does not follow a regular pattern within the period under consideration.

Mussel‐inspired two‐dimensional freestanding, alkyl‐polydopamine (alkyl‐PDA) Janus nanosheets, with a well‐controlled nanometer thickness and a lateral size of up to micrometers, have been developed. A self‐assembled octadecylamine (ODA) bilayer is used as the reactive template for the dopamine polymerization, resulting in the formation of well‐defined nanosheets. The alkyl‐PDA nanosheets show an amphiphilic nature with hydrophilic PDA and hydrophobic alkyl chains on opposing sides. The nanosheets can be used to functionalize many substrates and is dependent on the configuration of surface of the nanosheets. The nanosheets are quite stable, as the morphology is preserved after carbonization at 900 °C. Post‐modification of the nanosheets can be easily achieved because of the reactive nature of PDA. This work will provide a new strategic approach for fabricating polymeric Janus nanosheets, which can find applications for surface modifications, catalyst supports, and guided self‐assembly.
