Near‐Field Electrospinning Micro‐Printhead Achieves Precise Control of Nanofiber Deposition

Advanced Engineering Materials, EarlyView.
A micro‐printhead for near‐field electrospinning enables reproducible deposition of polymer nanofibers with diameters below 50 nm. Systematic parameter studies uncover the mechanisms linking operating conditions to fiber morphology, paving the way for precise and low‐cost nanoscale 3D manufacturing.As a high‐resolution, cost‐effective, and rapid ...

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows

Advanced Engineering Materials, EarlyView.
A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...

Aspiração folicular por via transvaginal guiada por ultra-som em eqüinos

Acta Scientiae Veterinariae, 2018
A tecnica de aspiracao folicular transvaginal guiada por ultra-som (TUGA) foi utilizada pela primeira vez em reproducao assistida de equinos em 1992 e desde entao vem sendo aperfeicoada. Com o crescente interesse nos procedimentos de transferencia de oocitos (TO), transferencia de gametas intrafallopiana (GIFT) e mais recentemente na transferencia ...

Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Soil erosion as a result of phosphate fertilization on estimated aggregate stability in a typic Acriferric Red Latosol
Perda de solo por erosão em decorrência da ação de adubação fosfatada corretiva sobre a estabilidade de agregados estimada em um Latossolo Vermelho Acriférrico típico

Semina: Ciências Agrárias, 2011
Phosphorus application in Brazilian soils is a common practice and such operation may affect some soil properties. Thus, with the objective of measuring the effect of the phosphate fertilization on aggregate stability and soil loss by erosion of a typic ...

Symbolic Regression and Multi‐Objective Optimization of the Flory–Huggins Interaction Parameter for Hydrogels

Advanced Engineering Materials, EarlyView.
We develop a data‐driven method to derive the mathematical expressions of the Flory–Huggins interaction parameter χ for the swelling behavior of temperature–responsive hydrogels. Starting from initial assumptions of χ, our workflow combines Bayesian optimization, Flory–Rehner theory, and symbolic regression to generate candidate χ expressions.

Optimization of the Production of Rubber Compounds Using Mathematical Models

Advanced Engineering Materials, EarlyView.
Rubber compounds were mixed in a batch internal mixer, and symbolic regression was used to derive mathematical models linking recipe and process parameters to ram path, torque, and mixing quality (incorporation, dispersion, distribution). Subsequent optimization with evolutionary algorithms identified operating conditions that reduce specific energy ...
