Plus module of Materials Studio software (2016, BIOVIA, San Diego, CA, USA) was utilized to import and optimize the structure through energy minimization under COMPAS II force field [21, 22].
Forcite module was used to analyze geometry optimization for the long chain of colloid.
Thus, structural optimization should be conducted to the system first to lower the potential energy, and then forcite can be used for optimization.
Then, to validate our calculations we also re-optimized the unit cell with three different simulation approaches: the local density approach (LDA) of Castep package , the revised the Perdew-Burke-Ernzerhof (RPBE)  level of the generalized gradient approximation (GGA) of [DMol.sup.3] package  and atomic based with adjusted basis set Newton-Raphson (ABNR) approach of Forcite package , DNP atomic basis sets were used in RPBE approach of [DMol.sup.3], which are comparable to 6-31G** sets , LDA optimization was performed with the same convergence criteria of PBEsol calculations (see above), and the RPBE and ABNR calculations were performed with fine criteria of the packages separately.
[36.] Forcite package is available as part of Materials Studio.
. It can search for a minimum energy structure.
, his helmet includes a "heads-up" display that shows critical information in front of the wearer's eyes, delivers turn-by-turn GPS by voice, and links to the automatic number-plate recognition system used by police, which identifies vehicle registration details and checks if there are any infringements.
In this paper, the resonant behavior of doubly clamped silicon nanobeams is first studied by using a specific computer module, Forcite
, which is based on the molecular dynamics method.

We also used Forcite
module from Accelrys Materials Studio 6.0.
