Circular cylindrical shells - An approximate solution

open access: yesInformes de la Construccion, 1984
This work presents a simplification of the analysis of cylindrical shells with circular directrix and proposes an approximate solution obtained by factorizing the total work into two simpler ones, longitudinal and transversal. This factorizing process is made possible by introducing a virtual load for longitudinal work which is subtracted from that ...

Lignocellulosic Triboelectric Materials for Energy Harvesting and Emerging Applications: A Review on Lignin‐Molecular Engineering toward Improved Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Contrasting sustainable biomass with depleting petroleum resources, this review charts the evolutionary timeline of lignin‐based TENGs. We systematically evaluate their fundamental mechanisms, enhancement strategies, and applications in green self‐powered electronics.

An Experimental Study of Thermal Energy Storage With Phase‐Change Material in a Rectangular Box Filled With Aluminum Foam

open access: yesEnergy Science &Engineering, EarlyView.
We experimentally evaluate a rectangular latent‐heat thermal energy storage box filled with paraffin RT57. Embedding 1–3 aluminum‐foam pieces (ε ≈ 0.89 and 10 PPI) increases effective thermal conductivity, making the temperature field more uniform and accelerating phase change.

Structural and Functional Stability of Natural Actomyosin From Freshwater Snail (Bellamya bengalensis): Unraveling Thermal and pH Effects

open access: yesFood Chemistry International, EarlyView.
Natural actomyosin from B. bengalensis exhibited maximum solubility (∼69.9%) at 40°C and stability near neutral pH, with minimum solubility at pH 4. Surface hydrophobicity and emulsifying activity peaked at 50°C, whereas Ca2+‐ATPase and foaming peaked at 40°C. DSC and SDS–PAGE confirmed denaturation above 40°C.
