Mesoporous Silica Formed with Triblock Copolymers

Popular Abstract in Swedish En amfifil molekyl har två delar; en del som dras till olja och en del som dras till vatten. Dessa två delar benämns vanligen huvudgrupp respektive svans. Amfifila molekyler kallas ofta tensider (på engelska surfactants), och är de aktiva beståndsdelarna i bland annat tvättmedel och hårschampo. Amfifila molekyler i vattenlösning formar sig så att vattendelarna dras tillThe formation of highly ordered mesoporous silica materials, using PEO-PPO-PEO amphiphilic triblock copolymers (so-called Pluronics) as structure directing agents, has been studied. The materials are formed through the addition of a silica source to a polymer solution of low concentration (2.5 wt ) under acidic conditions. The products have BET surface areas of approximately 800 m2/g. The unit cel

Free and Open Source Enterprise resource Planning: Systems and Strategies

Free/Open Source Enterprise Resource Planning systems (FOS-ERP) are gaining popularity and acceptance due to two main factors: their lack of licensing fees and customizability. Given this, organizations are able to easily adopt and manipulate these systems to meet their individual needs. Free and Open Source Enterprise Resource Planning: Systems and Strategies unites research on FOS-ERP, comparin

Abstract in Danish Marcel Proust (1871-1922) er en af det tyvende århundredes mest indflydelsesrige forfattere. Han, der var både rig og feteret, og så let som ingenting kunne have gjort livet bekvemt for sig selv, ofrede sig fuldkommen for sit romanværk À la recherche du temps perdu (1913-27).Med denne bog får man for første gang mulighed for at læse om Proust i Danmark – i 100 år – og en eneståe

Cost drivers and production limitations for electrified vehicle traction components

The automotive industry is shifting from internal combustion engines towards electrified drivetrains, containing electrical machines, power electronics and battery systems. The major hurdle in gaining customer acceptance for this type of drivetrain is the increase in price, due to hybrid drivetrains featuring an additional power system and pure electric systems requiring a major investment in

Development of infrared spectroscopy techniques for environmental monitoring

Infrared spectroscopy techniques have long been utilized in identifying and quantifying species of interest to us. Many of the elementary molecules in the atmosphere interact with infrared radiation through their ability to absorb and emit energy in vibrational and rotational transitions. A large variety of methods for monitoring of molecules and aerosol particles by collecting samples or by using
