AI Thread Summary
The discussion centers on the structure of boehmite, specifically γ-AlOOH, and its application in colloidal systems. Participants highlight that boehmite colloids, often utilized in composites and nanocomposites with polymers, typically exhibit rod-like shapes and can form a nematic liquid-crystal phase in certain conditions. One user seeks to calculate the free energy of their boehmite rod colloids using Tinker and assess molecular attraction to solvents with Gaussian, but requires a detailed molecular structure for input. They request publications or resources related to boehmite rods and their liquid-crystal properties to aid in their research. The conversation emphasizes the need for a comprehensive description of the system to facilitate better assistance.

hello
does anyone have any idea for the structure of boehmite?
i only found that is the γ - AlOOH.

any links would be really helpfull. ty.

sorry for my english
 
Chemistry news on Phys.org
thank you very much.


i have a colloidal that is boehmite.the structure of the coloidal would be like a polymer assuming that the monomer has the structure above?

thank you.sorry for my english
 
We really can't help you much unless you completely describe your system and try to write down exactly what you want to know about the structure.

In general, Boehmite colloids are used for making composites (more recently, nano-composites) with polymers like polyamides. The boehmite particles have been observed with highly anisotropic rod-like shapes. The synthesis itself often involves a colloidal dispersion in some dilute acidic medium that, at certain concentrations exhibits a nematic, liquid-crystal phase.
 
i have a colloidal system of boehmite rods.beside the dls sls mesurments i want to calculate its free energie of the system using a programme called tinker and i also want to calculate the attraction between the molecule and the solvent using another programme called gaussian.
To run this programmes i have to give them as input the structrure of the molecule ( in this case colloid ) i want to be calculated.i have no idea what is the structure of a colloid molecule.
thank you
 
any publication about boehmite rods like shape and liquid cristal phase to give or show ?
Thank you
 
I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
I'm trying to find a cheap DIY method to etch holes of various shapes through 0.3mm Aluminium sheet using 5-10% Sodium Hydroxide. The idea is to apply a resist to the Aluminium then selectively ablate it off using a diode laser cutter and then dissolve away the Aluminium using Sodium Hydroxide. By cheap I mean resists costing say £20 in small quantities. The Internet has suggested various resists to try including... Enamel paint (only survived seconds in the NaOH!) Acrylic paint (only...
