The phrase "additionally it was observed" is correct and usable in written English.
It can be used to introduce supplementary information or findings that support or add to a previous statement.
Example: "The initial results were promising; additionally, it was observed that the participants showed increased engagement over time."
Alternatives: "furthermore, it was noted" or "in addition, it was found".
Additionally, it was observed that the newly constructed superhydrophobic coatings display mechanical durability.
Additionally it was observed that tidal characteristics are dominant process in semi-diurnal regime.
Additionally, it was observed that the liquid paths inside the sponge start to fluctuate with a higher superficial liquid velocity.
Additionally it was observed that complimentary caloric effects are competing in nature and could act to oppose one another.
Additionally, it was observed that a slight increase on the ultimate load can be obtained by diminishing the patch thickness.
Additionally, it was observed that hydrate particles were formed with and without sand, and that the wall-attached hydrate layer presented a sandwich structure.
Additionally, it is observed that the proposed MPSO-ELM algorithm achieves higher accuracy and obtains compact network architecture compared to conventional ELM and BPNN classifier.
Additionally, it is observed that the reaction rate of the second absorption step improves, even after a total of 36 cycles.
Additionally, it is observed that the ensembling approach enables the proposed method to effectively tackle the flaws associated with optimization of large scale problems.
Additionally, it is observed that there is an optimal, finite number of resonators which gives a bandgap that is wider than the infinite-resonator bandgap, and that the optimal number of resonators increases with target frequency and added mass ratio.
Additionally, it is observed that the RLSMR method with the aid of the hybrid technique successfully solves the ill-posed damage equation and provides better damage detection results compared with the Tikhonov regularization technique.
