Detailing for a research centre in Antarctica: An experiment to force students to be creative instead of copying standard solutions

In order to equip architecture students with ambitious detail designing ability, related courses of the architecture programs should deal with subjects which are rather rare and unusual for real life practices in order to prevent students copying standard details. In 2015 an innovative project brief has been given to architecture students of Istanbul Technical University. The scenario given in the brief is to design a research station for the first group of Turkish scientist, to be built in one of the coldest and most arid regions on earth; the Antarctica. The performance requirements given in the brief were determined to prevent the students from copying details from any kind of resources as the total number of details generated in real life for those conditions are very limited and specific. The method used has demonstrated a great success and creative detail solutions were generated by the students. In the paper, the innovative coursework brief for bettering the detail design ability of architecture students is explained and the output of the studio is presented.

Strategies for the one-step immobilization–purification of enzymes as industrial biocatalysts

In this review, we detail the efforts performed to couple the purification and the immobilization of industrial enzymes in a single step. The use of antibodies, the development of specific domains with affinity for some specific supports will be revised. Moreover, we will discuss the use of domains that increase the affinity for standard matrices (ionic exchangers, silicates). We will show how the control of the immobilization conditions may convert some unspecific supports in largely specific ones. The development of tailor-made heterofunctional supports as a tool to immobilize–stabilize–purify some proteins will be discussed in deep, using low concentration of adsorbent groups and a dense layer of groups able to give an intense multipoint covalent attachment. The final coupling of mutagenesis and tailor made supports will be the last part of the review.
