1. 1. Design of a solvent recovery system in a pharmaceutical manufacturing plant

   University essay from KTH/Skolan för kemivetenskap (CHE)

   Author : SHASHANK BHANDARI; [2016]
   Keywords : Batch distillation; liquid-liquid extraction; pressure swing distillation; pharmaceutical manufacturing; sustainable development;

   Abstract : Solvents play a crucial role in the Active Pharmaceutical Ingredient (API) manufacturing and are used in large quantities. Most of the industries incinerate the waste solvents or send it to waste management companies for destruction to avoid waste handling and cross-contamination. READ MORE

   Abstract : A spin-cast silicone membrane has been successfully bonded between two injection-molded microstructured plastic discs. This sandwich structure creates a useful platform for mass production of microfluidic systems, provided that the bonds are leakproof. READ MORE

4. 3. Micro-Structuring of New Materials Combined with Electronic Polymers for Interfaces with Cells

   University essay from Biomolekylär och Organisk Elektronik; Tekniska högskolan

   Author : Alexander Vastesson; [2012]
   Keywords : Off-Stoichiometry Thiol-Ene; Polydimethylsiloxane; Microsystems; Nanosystems; Conducting polymers; HEP G2 cells; Cell viability; Soft lithography; DNA;

   Abstract : Materials based on novel Off-Stoichiometry Thiol-Ene polymers, abbreviated OSTE, show promising properties as materials forlow cost and scalable manufacturing of micro- and nanosystems such as lab-on-chip devices. The OSTE materials have tunablemechanical properties, offer possibility for low temperature bonding to many surfaces via tunable surface chemistry, and can beused in soft lithography. READ MORE

5. 4. Controlled deposition and alignment of electrospun PMMA-g-PDMS nanofibers by novel electrospinning setups

   University essay from KTH/Skolan för kemivetenskap (CHE)

   Author : Bashar Haseeb; [2011]
   Keywords : Electrospinning; nanofibers; nanofiber alignment; PMMA-g-PDMS; controlled deposition; triple electrode.;

   Abstract : Electrospinning is a useful technique that can generate micro- and nano-meter sized fibers from polymer materials. Modification of the electrospinning parameters and apparatus can generate nanofibers for use in diverse applications ranging from tissue engineering to nanocomposite fabrication; however, electrospun fibers are typically collected in a random orientation and over large areas limiting their applications.

6. 5. DNA chips with conjugated polyelectrolytes as fluorophore in fluorescence amplification mode

   University essay from Institutionen för fysik, kemi och biologi

   Author : Karin Magnusson; [2008]
   Keywords : Soft lithography; conjugated polyelectrolyte CPE ; DNA-chip; fluorescence microscope; Fluorescence Resonance Energy Transfer FRET ;

   Abstract : The aim of this diploma work is to improve selectivity and sensitivity in DNA-chips by utilizing fluorescence resonance energy transfer (FRET) between conjugated polyelectrolytes (CPEs) and fluorophores. Leclerc and co-workers have presented successful results from studies of super FRET between fluorophore tagged DNA and a CPE during hybridisation of the double strand. READ MORE
