To prepare core samples for imbibition experiments, standard core plugs were cut from a whole core which was taken from a carbonate reservoir located in the south of Iran.
Various works have been also investigated to prepare core shell-like particles such as polystyrene core and poly NIPAM) shell [ 6– 9].
Huang [22] and Mirkin [23] have prepared core-shell structure with triangular nanoplates as core.
This coaxial wet-spinning technology is further extended to prepare core-sheath GFs [56].
The selected glass compositions were then used to prepare core-cladding optical preforms by using a modified built-in casting technique.
A coaxial electrospinning process including a polyvinyl chloride (PVC -coated concentric sPVC -coateds implemented to prepare concentric nanofiberspinneretcetin using an un-spinnable shell fluid containing PVP and quercetin.
The strategy to prepare core-shell SiO2@Fe3O4-Tat NPs involves four steps, consisting of synthesis of Fe3O4 nanoparticles by co-precipitation, growth of a silica shell, surface amination, followed by conjugation of Tat peptide through EDC/NHS coupling reactions, as depicted in Scheme 1.
While the fastest way to measure tree rings is to measure prepared cores or stem discs directly (e.g., with the LinTab™ System [Frank Rinn, Heidelberg, Germany]), this method is very time-consuming if rings are sometimes indistinct, in which case it becomes necessary to compare and re-measure the original cores (Levanič, 2007).
Sometimes, the unavailability of shale sample and difficulty in preparing shale core plug also limit the number of experiment.
Four new funds are on deck Building on the success of the Local Initiatives Fund, RSF is preparing with core donors to launch four new Integrated Capital Funds: the RSF Fair Trade Fund, RSF Biodynamics Fund, RSF Soil Health Fund, and RSF Women's Fund.
After preparing appropriate cores from the blocks, uniaxial compressive strength test was performed on rock cores.
