Organic-inorganic lead halide perovskite compounds are shown to be very promising candidates for low cost, solution-processable, highly efficient (>22%) solar cells with a...

Dit rapport is voortgekomen uit een materiaalscriptie, die Sebastiaan Ostkamp in 1994 maakte voor zijn studie Europese Archeologie aan de Universiteit van Amsterdam, begeleid...

In recent years nano- and microparticles composed of polymeric or lipid material have been proposed as drug carriers. Their use allows the modification of the biopharmaceutic...

Hydrogen chloride exhibits a complex phase diagram account made of its simple molecular structure. Three crystalline phases are known to exist at ambient pressure below its...

Silica glass is one of the most widely studies amorphous materials. It is the archetypal glass former, comprising a network of corner-shared SiO4 tetrahedra. Recently a lot of...

Off-specular neutron reflection is potentially a powerful technique for studying the lateral organisation of phospholipid bilayers. However, this has not yet been demonstrated....

The crystal unit cell of mayenite, 12CaO.7Al2O3, consists of a cubic lattice of [Ca24Al28O64]4+ with the remaining 2*O2- contained in cages, which are linked by channels within...

Liquid HCl has attracted numerous studies focusing onto the role played by hydrogen bonding on the dynamical properties of this weakly associated liquid. Previous computational...

Crystals of the filled skutterudite PrFe4Sb12 with the 73~87% Pr-site filling fractions prepared under ambient pressure show some magnetic ordering around 5 K and their...

In this application we will conduct the first detailed study of the structure of glassy metal-ammonia systems ? so-called Ogg glasses, named after the person who first proposed...

Following a recently succesfull measurement of the structure of a monolayer of n-butane adsorbed on MgO we wish to perform neutron diffraction measurements of monolayers of...

For the first time, the research team aim to use INS to characterise a series of new high specification methane reforming catalysts. The enhanced performance of these catalysts...

The objective of this experiment is to characterise four particular high-pressure polymorphs of various hydrates discovered by us in recent years during work carried out using...

We ask for 3 days on GEM to study in-situ the decomposition of the Na-substituted LiNH2 phases, Li1-xNaxND2, LiNa2(ND2)3, Li3Na(ND2)4 and their reactions with LiD. LiNH2 is the...

The aim of this proposal is to determine the in-plane and out-of-plane structure of H2 in the two dimensional galleries of stage-I calcium-ammonia-graphite intercalates: this...

The proposed experiment aims to study the dynamics of trehalose/glycerol mixtures and lysozyme in presence of trehalose/glycerol mixtures at different relative concentration....

Progress in the development of nano-sized hybrid therapeutics and nano-sized drug delivery systems - "nanomedicines" - over the last decade has been remarkable. One key...

Oxide ceramics based on ceria, CeO2, have been the subject of considerable research for the role of solid electrolyte within solid oxide fuel cells (SOFCs), since their ionic...

Some of the most important chemical reactions involve Brønsted acids and bases where the solvation structure and transport dynamics of charged defects in hydrogen-bonded...

To our knowledge, the length of the U¿H single bond has never been accurately measured, at least not in a molecular compound by single-crystal neutron diffraction. We currently...
