A Dislocation Perspective on Strength and Toughness in Ceramics
Advanced Engineering Materials, EarlyView.Dislocations in ceramics enjoy a long but yet under‐appreciated history. The three research waves for dislocations in ceramics highlight the topic evolution over the last 90 years. This review focuses on the impact of dislocation on strength and toughness in ceramics.

Advanced Engineering Materials, EarlyView.This study applies machine learning regression to predict chromium layer thickness in decorative trivalent chromium electroplating, using 441 experiments from laboratory‐scale (1L) and pilot‐scale (14L) setups. Tree‐based models, particularly CatBoost, outperformed linear regression by capturing nonlinear parameter interactions (R2$R^2$ up to 0.77 ...

Effect of DBTDL Cure Catalyst on Mechanical and Ballistic Properties of a Composite Igniter [PDF]
فناوری در مهندسی هوافضا, 2020 Igniters are main sections of motor that initiate the ignition of propellant grain. Large motors usually use pyrogen composite igniters. Pyrogen igniters have similar formulation with solid composite propellants, but their burning rate is relatively high.

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions
Advanced Functional Materials, EarlyView.This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Development of Strand Burner for Solid Propellant Burning Rate Studies
, 2013 It is well-known that a strand burner is an apparatus that provides burning rate measurements of a solid propellant at an elevated pressure in order to obtain the burning characteristics of a propellant. This paper describes the facilities developed by

From Food to Power: Hydrogel Thermoelectrics for Ingestible Electronics
Advanced Functional Materials, EarlyView.We introduce a fully edible thermoelectric–electrochromic platform that harvests heat from food and converts it into a visible color change. N‐type and p‐type hydrogel thermoelectric generators connected in series power anthocyanin‐based electrochromic displays, demonstrating the feasibility of safe, biodegradable, ingestible systems for on‐food ...

Burning Rate Characteristics of Magnesium Sodium Nitrate Propellants
, 2013 The combustion phenomena of Mg-NaNO/sub 3/ propellants have been studied. Results of burning rate at different mixture ratios and particle sizes indicate that the compositions containing finer particle size (50 millimicron) NaNO/sub 3/ give higher ...
