2. 1. Radiobiological investigations of proton and light ion therapy

   Author : Nina Tilly; Michael Scholz; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiobiology; Monte Carlo method; Radiotherapy; high-energy instrumentation; Protons; Light ions; RBE; LET; Radiobiological models; Radiobiologi; medicinsk strålningsfysik; Medical Radiation Physics;

   Abstract : During the last decade, the interest in proton and light ion beam therapy has increased considerably and several new centres are planned around the world. These particles have a large advantage due to their sharp physical dose distributions as compared to conventional radiotherapy beams. READ MORE

4. 2. Dispersion Engineering : Negative Refraction and Designed Surface Plasmons in Periodic Structures

   Author : Zhichao Ruan; Min Qiu; Henri Benisty; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photonic crystal; dispersion property; negative refraction; surface plasmon polariton; designed surface plasmon; negative index material; layer-KKR method; finite-difference time-domain method; plane wave method; subwavelength imaging; open cavity; enhanced transmission; slowing light; Photonics; Fotonik;

   Abstract : The dispersion property of periodic structures is a hot research topic in the last decade. By exploiting dispersion properties, one can manipulate the propagation of electromagnetic waves, and produce effects that do not exist in conventional materials. READ MORE

5. 3. A scattering study of concentrated lens protein solutions and mixtures - Towards understanding the molecular origin of presbyopia

   Author : Saskia Bucciarelli; Fysikalisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; scattering; eye lens; presbyopia; dynamical arrest; crowding; proteins; dynamics; crystallins;

   Abstract : Healthy eye lenses are transparent and flexible, able to adapt shape in order to focus on far away and close-by objects. With age, however, this flexibility is lost, leading to a condition known as presbyopia. This vision disorder where close-by objects appear blurred commonly starts around the age of 40. READ MORE

6. 4. Studies of Molecular Interactions with Single Nanoparticles: Combining in Situ Plasmonic Nanospectroscopy with Transmission Electron Microscopy

   Author : Sara Nilsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; oxidation; plasmonic nanospectroscopy; heterogeneous catalysis; localized surface plasmon resonance sensing; grain boundary; transmission electron microscopy; single nanoparticle; palladium hydride; dark-field scattering spectroscopy;

   Abstract : The cyclic methanol and hydrogen economies are two viable options in the strive for clean energy production. Industrial methanol synthesis is conducted over copper (Cu)-based catalysts. However, Cu is prone to oxidation, which leads to Cu catalyst deactivation. READ MORE

7. 5. Fashioning the Ecological Crisis : Sustainability and Feminism in Fashion Advertising and Communication in Contemporary Sweden

   Author : Mariko Takedomi Karlsson; Humanekologi; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; feminism; femvertising; fashion; advertising; marketing; sustainability; consumption; gender; greenwashing; social media; feminism; mode; reklam; marknadsföring; hållbarhet; konsumtion; genus; sociala medier; femvertising; greenwashing;

   Abstract : The corporatisation of social justice (gender justice, LGBTQI+ rights, racial justice) and environmental justice ideals in the last decades has grown immensely in western countries, exemplified by rainbow-clad ATM’s during Pride month or Nike using images of NFL player Kaepernick’s anti-racism protest action of taking a knee during the USA national anthem in a marketing campaign. One of the industries that has been particularly inundated with symbols of social justice is the fashion industry. READ MORE
