The essence of nonlinear polymer rheology: everything you must know

by Shi-Qing Wang, University of Akron, USA

Polymer processing suffers from a variety of rate-limiting difficulties. In extrusion alone, we encounter surface roughness on extrudate (sharkskin), quasi-periodic extrudate distortion associated with pressure oscillation and gross melt fracture.  To have better mechanical characteristics, polyolefin resins need to have sufficiently high molecular weight, and the same is true for rubbers.  Consequently, useful polymers, in the annual amount of one hundred million tons, are always strongly entangled.  Most of the melt processing instabilities of these polyolefin and rubbers are due to the presence of high entanglement.  Our task is to understand and predict rheological responses of entangled polymeric materials.

This presentation summarizes more than one decade of intensive research carried out at Akron that has completely changed our worldview of the essence of nonlinear rheology of entangled polymers.  Continue reading “iRTG lecture series by Shi-Qing Wang (October 14, 2019) | part 1”

Funding Opportunities for Early Career Scientists with focus on DFG Research Grants (November 25, 2019)

Within this workshop, you are quickly guided through some research funding organizations and funding opportunities suitable for early career scientist. Central aim of the workshop is to shed light on the detailed structure as well as all formal aspects of the DFG-proposal (Basic Module & Module Temporary Positions for Principal Investigators). Continue reading “Funding Opportunities for Early Career Scientists with focus on DFG Research Grants (November 25, 2019)”

Good scientific practice seminar (November 26, 2019)

This seminar presents the basic principles and rules of good scientific practice. Fundamentals of scientific work, i.e. professional standards and documentation of results, are discussed. Further topics are handling of primary data (backup and storing) and scientific publications (authorship and scam journals). Also management of research data, following the FAIR principles is briefly introduced. Recent examples of scientific misconduct illustrate the official procedures at the institutions and possible consequences. The rules apply worldwide and for all subjects and every researcher at Martin Luther University Halle-Wittenberg and the Max Planck Institute of Microstructure Physics has to comply with these rules. 

Target audience

Doctoral students and PostDocs Continue reading “Good scientific practice seminar (November 26, 2019)”

Know your competencies – find your job: job search for scientists (January 21-22, 2020)

Scientists have lots of job options, but are often not aware of them. This workshop will support you to see more them on the German labour market. You will learn to go the different steps of job search: to be aware of your competencies, skills and knowledge and to build your career strategies based on them.

Polyelectrolyte Solutions: The least understood form of condensed matter

by Ralph H. Colby, The Pennsylvania State University, USA

Polyelectrolytes are polymer chains with covalently bonded ions and oppositely charge counterions. The combination of electrostatic interactions and conformational entropy of polymer chains led Nobel Laureate de Gennes to term this class of materials as the least understood form of condensed matter. Yet polyelectrolytes are essential for life, as DNA and RNA are both polyelectrolytes. Continue reading “iRTG lecture series by Ralph Colby (October 28/30, 2019) | part 2 and 3”

Recruit an intern from North America, Great Britain or Ireland | RISE 2020

Would you like to recruit an intern from North America, Great Britain or Ireland as support for your experimental work? Offer an internship as part of your doctoral thesis.

RISE Germany recruits Bachelor students from North American, British and Irish universities for a research stay. The DAAD supports the research internships taking place in the summer months with scholarships, financed by funds from the Federal Foreign Office and through institutional cooperation. 300 internships are arranged annually.

Offer an internship in your project. Please submit your proposal from September 1 – October 15, 2019.
