One cost-reduction strategy involves the use of finite element simulations; however, this technique demands significant engineering time and validation efforts. This study proposes a novel method for designing cylindrical bottles, facilitating the automated generation of preparation mold geometries for manufacturing. Key findings include the successful parameter-based analysis accounting for container capacity, mass, and height-to-diameter aspect ratio which was experimentally validated across several container sizes against traditional experimental iterations. Validation tests demonstrated that the automatically generated geometries yield functional bottle designs capable of withstanding compressive loads. The primary advantage of this approach lies in a substantial reduction in development time, from 32.9 to 18.3 days, providing a significant competitive edge. However, the current methodology is applicable to only 6% of the bottles in the production range.

Elemental depth profiles and leaching behavior are evaluated using TOF-SIMS and ICP-OES. The results reveal that the effect of γ-irradiation on corrosion would soon recover after 1 day. Over longer periods, the corrosion behaviors of both pristine and irradiated samples become similar. Additionally, 800 kGy γ-irradiation leads to a 30% increase in Na and B leaching in NBS9 in 16 days, along with enhanced initial leaching rates. However, despite these changes, the residual leaching rate of NBS9 remains constant, suggesting that increased corrosion may also promote the formation of passivating layers.

The need for antifogging characteristics of soda-lime-silica (SLS-) based window glasses requires feasible solutions. Superhydrophilicity is generally achieved by textured surfaces with suitable features or any chemical modification including thin films. Fabrication of textured surfaces usually involves sophisticated facilities that are often expensive. This paper reveals a novel approach to achieving superhydrophilic SLS surfaces by flame-impingement. The chemical energy of methane gas was converted into thermal energy by a flame torch to reach temperatures just above the softening point of SLS glass. The glass surface was exposed to the flame at a distance of around 100 mm for 10 s. The surface was transformed into a superhydrophilic state with a static contact angle of nearly zero after the treatment. This property was remarkably retained on exposure of the surface to the ambient atmosphere for 3 years of aging. The subsurface structural modifications accountable for the alteration in wetting behavior by the influence of flame-impingement were investigated. High-resolution X-ray photoelectron spectroscopy of the O1s spectral line evidenced the repolymerization of vicinal silanols into bridging oxygens (BOs), accompanied by the loss of hydrous species (SiOH/H<sub>2</sub>O) in the near-surface region. The repolymerized BOs acted as adsorption sites of water molecules to promote superhydrophilicity. Atomic force microscopy exhibited the conversion of an open silica tetrahedral network with nonbridging oxygens into closed rings.
