The invention of the laser in 1960 gave us the ruby laser, which generally produced chaotic pulses of light. Six years later, in 1966, a concept called passive mode-locking applied to neodymium-glass lasers produced reasonably well-behaving picosecond pulses. This triggered an intense activity, with respect to developing improved laser pulse sources, measurement techniques, and application to chem
Plastic waste has come to the forefront of academic and political debates as a global problem that demands an urgent solution. Promoted by policymakers, academia, and corporations alike, the circular economy model presents a viable path to reach more sustainable levels of development. Emerging and disruptive technologies can catalyse the transition to a circular economy, but their application to t
An experimental study to characterize properties controlling delamination of paperboard is presented. The normal and shear traction–separation laws are measured and evaluated using a double cantilever beam (DCB) and a split double cantilever beam (SCB) specimen. The DCB-experiments provides normal separation data in good agreement with results using alternative experimental techniques. From the me
Synchrotron X-ray diffraction patterns for highly crystalline MCM-41 a mesoporous silicate molecular sieve are presented. The form factor observed in seven orders of diffraction is used to show the existence of a two-layer wall structure, with a narrower mesopore than previously assumed, and much void space in the walls.
Cross-laminated timber (CLT) is an engineered wood product constructed by combining multiple layers of wood lamellae with adhesives. In the serviceability state, structural timber elements, that are light–weight, are more susceptible to complications regarding the vibration level, than heavier structural elements such as concrete. Contemporary standard practice in the building industry, is to use
Bio-based materials are considered to be an effective alternative to fossil-based materials and are being studied globally. It will be a long journey for the commercialisation of bio-based materials. Apart from waiting for the material technology to be mature, how will the material be rolled out to the market? This is the challenge faced by all material companies. The project is in collaboration
The packaging market is starting to demand renewable materials to face out the fossil based materials mainly used today. This thesis investigate the possibility and advance to switch from conventional grades of polyethylene (PE) and polyethylene terephthalates (PET) towards bio-produced qualities of the same polymers. The work is divided into two parts starting with a carbon dioxide evaluation of
Food wastage during distribution, retail sale, and consumption is a concern of great worry. It not only affects the economics of businesses but also puts natural resources under severe stress. For example, in the UK some 800,000 tons of bakery products are purchased each year and never eaten, mainly due to short life span of the product. Earlier investigations at Lantmännen Unibake, UK have identi
Previously proposed high spin states in Na22,23 are compared with calculations from the cranked Nilsson model including Strutinsky renormalization. High K rotational isomers are proposed for Iπ=6- in Na22 and 11/2+, 13/2+, and possibly 15/2+ in Na23. The positive parity yrast sequences in these two nuclei are analyzed in terms of the change from collective to single particle behavior at I=9 (22Na)
The transition quadrupole moments. Q(t), of four weakly populated collective bands up to spin similar to 65h in Er-157,Er-158 have been measured to be similar to II eb demonstrating that these sequences are associated with large deformations. However, the data are inconsistent with calculated values from cranked Nilsson-Strutinsky calculations that predict the lowest energy triaxial shape to be as
Measurements of top quark spin observables in tt¯ events are presented based on 20.2 fb−1 of s=8 TeV proton-proton collisions recorded with the ATLAS detector at the LHC. The analysis is performed in the dilepton final state, characterised by the presence of two isolated leptons (electrons or muons). There are 15 observables, each sensitive to a different coefficient of the spin density matrix of

Popular Abstract in English The energy demands of human society are huge and will keep increasing for the foreseeable future. Fossil fuels have largely been able to meet those demands for the last centuries, but issues of sustainability and global warming have brought about a need for alternative energy sources. The emission of the sun supplies earth with an energy that is many thousand times largOrganic solar cells employing fullerenes blended with conjugated polymers as the main light-absorbing material have achieved power conversion efficiencies exceeding 10%. They hold promise as an alternative energy source with many advantages in terms of long-term sustainability and reduced greenhouse gas emissions. Detailed information on the electronic and geometric structure of the molecules invo
