Advanced Engineering Materials, EarlyView.This study explores the ablation efficiency and surface quality of laser‐treated stainless steel alloys (AISI 304, AISI 420, and AISI 316Ti) using an ultrashort pulsed laser and varying burst parameters (MHz, GHz, and Bi‐burst). Both ablation rates and surface quality parameters are determined, including isotropy surface roughness values, highlighting ...

A Novel Simplified Approach to Physically Simulate Wire‐Arc Directed Energy Deposition Conditions
Advanced Engineering Materials, EarlyView.Scarcity of specialized titanium alloy wires and high experimental wire production costs impedes wire‐arc directed energy deposition (waDED) adoption in industry. A novel, wireless approach is introduced to accelerate and economize titanium alloy development.

Physiological Values of P-Wave Dispersion in Silesian Breed Horses and Polish Primitive Horses
Journal of Veterinary Research, 2013 Electrocardiographic examinations were performed on 45 Silesian breed horses (group K, 3-16-year-old, 16 stallions, 29 mares) and on 25 Polish Primitive breed horses (group P, 1.5-19-year-old, two stallions, six geldings, 17 mares).

Advanced Functional Materials, EarlyView.PBTTT‐OR‐R, a C14‐alkoxy/alkyl‐PBTTT polymer derivative, is of substantial interest for optoelectronics due to its specific fullerene intercalation behavior and enhanced charge‐transfer absorption. Comparing this polymer with (S) and without (O) homocoupling defects reveals that PBTTT‐OR‐R(O) forms stable co‐crystals with PC61BM, while PBTTT‐OR‐R(S ...
