2. 21. Metal-assisted chemical etching for nanofabrication of hard X-ray zone plates

   Author : Rabia Akan; Ulrich Vogt; Muhammet Toprak; Carmen Vogt; Lucia Romano; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; metal-assisted chemical etching; zone plate; high-aspect ratio; silicon; nanostructures; Material and Nano Physics; Material- och nanofysik; Optik och fotonik; Optics and Photonics;

   Abstract : Hard X-ray scanning microscopes, or nanoprobes, make it possible to image samples and probe their chemical, elemental and structural properties at nanoscale resolution. This is enabled by the use of nanofocusing optics. Commonly used optics in nanoprobes for high resolution X-ray experiments are zone plates. READ MORE

4. 22. Centrifugal microfluidics-based point of care diagnostics at resource limited settings

   Author : Ahmad Saleem Akhtar; Aman Russom; Ines Fernandes Pinto; Nicole Pamme; KTH; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microfluidics; centrifugal microfluidics; point-of-care; low-cost; diagnostics; agarose beads; immunoassays; colorimetry; fluorescence; cytokines; nucleic acid amplification; isothermal amplification; COVID-19; portable; smartphone; resource limited settings.; Biotechnology; Bioteknologi;

   Abstract : Advancements in medical diagnostics have allowed us to understand the underlying mechanism and treat the root cause for many diseases which had been causing morbidity and mortality up until this point in human history. Furthermore, many of the standard diagnostic procedures have now been transformed to provide answers at or near the point-of-care. READ MORE

5. 23. The Biophysics of Na+,K+-ATPase in neuronal health and disease

   Author : Evgeny E. Akkuratov; Hjalmar Brismar; Anita Aperia; Stefan Wennmalm; Poul Nissen; KTH; []

   Abstract : Na+,K+-ATPase is one of the most important proteins in the mammalian cell. It creates sodium and potassium gradients which are fundamental for the membrane potential and sodium-dependent secondary active transport. READ MORE

6. 24. Gamma-ray Spectroscopy ofNeutron-rich 111 Mo, 85,87 Ge andSelf-Conjugate 88 Ru Far From Stability

   Author : Özge Aktas; Ayse Nyberg; Bo Cederwall; Augusto Machiavelli; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atomic; Subatomic and Astrophysics; Atomär fysik; subatomär fysik och astrofysik;

   Abstract : The neutron-deficient self-conjugate (N=Z) nucleus 8844 Ru 44 was populatedvia the heavy ion fusion evaporation reaction 54 Fe( 36 Ar, 2n) 88 Ru in an ex-periment performed at the GANIL accelerator laboratory in France. Usingthe AGATA γ-ray spectrometer together with ancillary detectors, promptγ − γ − 2n coincidence and charge particle anticoincidence analysis was per-formed for the low-lying energy spectrum of 88 Ru.

7. 25. Nanolatexes: a versatile toolbox for cellulose modification

   Author : Alexandros Efraim Alexakis; Eva Malmström; Justin Zoppe; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; nanolatexes; RAFT; PISA; adsorption; cellulose; modification; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : Cellulosic materials are widely used in our everyday lives, ranging from paperand packaging to biomedical applications. However, in most applications, cellulose must coexist with hydrophobic polymers which can be challenging due to its hydrophilic character. This has encouraged the exploration of chemical and physical modifications of cellulose. READ MORE
