Endoscopic view – stages of endoscopic removal of third ventricle colloid cyst: A – colloid cyst in the interventricular foramen, B – colloid cyst capsule’s coagulation, C – colloid cyst capsule’s incision, D – colloid cyst content’s aspiration, E – colloid cyst capsule’s removal, F – remnants of the colloid cyst capsule, G – coagulation of the colloid cyst capsule’s remains, H – view after total removal of the colloid cyst capsule, I – view at the third ventricle after total removal of the colloid cyst

UV–Vis spectra of AgNPs synthesized using sodium citrate (Colloid SC), (Colloid SC*); tannic acid (Colloid TA), (Colloid TA*); and a mixture of sodium citrate and tannic acid (Colloid SC–TA), (Colloid SC–TA*) at room temperature (Colloid SC, TA, SC–TA) and heated to 100 °C (Colloid SC*, TA*, SC–TA*)

(a) Streamlines and velocity maps for the motion in the x = 0 symmetry plane for a colloid translating in the positive z direction with velocity U on the surface of a semi-infinite liquid in the laboratory frame for λ/a = 0.01 and (a) a hydrophobic (θ = 7π/8, d/a = 0.2), (b) a neutral (θ = π/2, d/a = 1) and (c) a hydrophilic θ = π/8, d/a = 1.8) colloid assuming the liquid to be water. Streamlines and velocity maps for the motion of the fluid underneath a colloid rotating counterclockwise around the x axis with velocity aΩ on the surface of a semi-infinite liquid in the laboratory frame for λ/a = 0.01 and (d) a hydrophobic rotating colloid (θ = 7π/8), (e) a neutrally wetting (θ = π/2 colloid and (f) a hydrophilic (θ = π/8) colloid.
