1. 1. Study of luminescent and energy properties of CsPbBr3 and CsPbI3 nanoplatelets

   L3-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

   Författare :Taddeo Salique; [2022]
   Nyckelord :quantum confinement; nanoplatelets; CsPbBr3; CsPbI3; semiconductor; exciton; perovskite nanocrystals;

   Sammanfattning : Halide perovskite semiconductor nanocrystals have been studied a lot recently because they allow a precise control over the entire visible emission spectrum and as a result, the possibility of a variety of light-emitting applications. In this study, cesium lead bromide CsPbBr3 and cesium lead iodide CsPbI3 nanoplatelets of 3, 4 and 5 monolayers (ML) have been synthesized. LÄS MER

3. 2. An investigation of the interactions between clay nanoplatelets in the presence of monovalent and divalent salts, as well as cationic peptides utilising atomistic molecular dynamics

   Master-uppsats, Lunds universitet/Kemiska institutionen

   Författare :Mona Koder Hamid; [2020]
   Nyckelord :clay; molecular dynamics simulations; physical chemistry; fysikalisk kemi; theoretical chemistry; teoretisk kemi; Chemistry;

   Sammanfattning : Clays are negatively charged nanoplatelets with a layered silicate structure. It has been observed from small angle X-ray scattering measurements, and coarse-grained molecular dynamics simulations (CG-MD) that clay nanoplatelets are able to form stacks, known as tactoids, in the presence of divalent or multivalent counterions [8, 5].

4. 3. Fabrication and Evaluation of Sb2Te3/PVDF Hybrid Thermoelectric Films

   Master-uppsats, KTH/Tillämpad fysik

   Författare :Bo Yu; [2020]
   Nyckelord :;

   Sammanfattning : Thermoelectric (TE) materials and devices have been extensively studied for harvesting waste heat energy. There is more interest to fabricate TE materials and devices at low cost and highly-efficient ways. LÄS MER

5. 4. Multifunctional Wood Polymer Composites Reinforced with Graphene Nanoplatelets : Investigating if multifunctionality can be achieved in wood polymer composites through the addition of graphene nanoplatelets

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Vanessa Meulenberg; [2019]
   Nyckelord :Wood polymer composites; graphene; multifunctional; wood flour;

   Sammanfattning : Graphene nanoplatelets (GNPs) were used to reinforce wood polymer composites (WPCs) in order to achieve multifunctionality. Multifunctionality could be achieved through the GNPs because of their excellent mechanical and electrical properties. The research consists of two parts: HDPE/GNP/WF composites and LLDPE/GNP composites. LÄS MER

7. 5. Theoretical study of anisotropic effects in crystal growth on the example of concrete and calcium oxalate monohydrate

   Master-uppsats, Lunds universitet/Kemiska institutionen

   Författare :Vilhelm Ekberg; [2019]
   Nyckelord :anisotropic crystal growth; COM; C-S-H; PM6; ReaxFF$_{ textrm{SiO}}$; organizing molecular matter; nanochemistry; nanokemi; Chemistry;

   Sammanfattning : While many crystals, both natural and artificial, grow isotropically, there are examples of crystals growing anisotropically. The aim of this theoretical study was to confirm the growth modes displayed by three different crystals, representing 3D, 2D and 1D structures. LÄS MER
