Part I. Vibrational spectra and molecular shapes of monomeric trichlorides of aluminium, gallium, and indium High-resolution Raman and i.r. studies have been made on monomeric AlCl3, GaCl3, and InCl3 isolated in argon matrices at low temperatures. All the in-plane fundamentals of these ...
It is a characteristic of triple-shape polymers, that different combinations of shapes (A) and (B) for a given shape (C) can be obtained by adjusting the two-step programming process, whereby the two shape changes from (A) to (B) and from (B) to (C) are not limited to be ...

A crystallization monitoring system using a quartz crystal oscillator was utilized to predict different shapes of crystal formation by measuring crystal growth rate and to measure supersaturation. Applying different rates of cooling, crystal formation of different shapes was induced, and the frequency varia...
Nanoparticles (NPs) can now be synthesized with a wide array of controlled sizes, shapes, and properties. However, turning them into nanomaterials often requires packing them into ordered assemblies to manifest specific electronic or optical properties for applications in nanoelectronics, optics, and met...
As the above mentioned, an increase in lattice misfit could not only augment the particle size of γ′ precipitates, but also change the particle shape from spheroid to cuboid, and then to other irregular shapes3,81. Thereof, a moderate negative lattice misfit could obtain an optimal particle ...
Using the empirical growth model, two sets of zeolite membranes with different crystal shapes were prepared. The first set of membranes displays different grain morphologies ( M), but has comparable thickness ( τ) and grain size ( d). The second set of membranes has different τ/ d ratios,...
Three shapes of silicon carbide tensile specimens were tested - curved with a low stress-concentration factor and straight with a circular hole or an elliptical hole. The nominal thickness was 125 mum with a net section that is 100-mum wide; the overall length of these microspecimens was 3.1...
The preparation of adsorbents plays a vital role in the adsorption method. In particular, many adsorbents with high specific surface areas and unique shapes are essential for the adsorption strategy. A Zn–Mg–Al/layer double hydroxide (LDH) was designed in this study using a simple co-precipita...
