The Influence of Field‐Assisted Sintering Technology (FAST) Temperature and Cooling Rate on the Microstructural Evolution in Gamma‐Titanium Aluminide Alloy GE4822

Advanced Engineering Materials, EarlyView.
Controlling the Field Assisted Sintering Technology (FAST) parameters, dwell temperature and cooling rate, significantly influences the microstructural evolution in titanium aluminide GE4822. Significant γ‐lamellar colonies develop only upon cooling through the α‐transus.

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

Advanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

Superlubricity and Corrosion Inhibition Properties of Solvate Ionic Liquids in Hybrid Carbon Fiber Reinforced Plastic–Steel Interfaces

Advanced Engineering Materials, EarlyView.
Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

Design, Modeling, and Experimentation of Polar Robot: Assisted Sail and Multimode Motion for Energy Saving

Advanced Intelligent Systems
Polar robots are difficult to conduct long‐term scientific exploration in unmanned polar areas because of the limited energy supplied. A polar robot that utilizes assisted sail and multimode motion to achieve energy‐saving is proposed.

Reading and thinking about International Polar Years: five recent books

, 2013
Within the polar science community the Polar (and Geophysical) Years represent signal events. We often read, largely within geoscience literature, that those events represented positive and dramatic steps forward in international science.

Architecture‐Driven Sensor Stability in Weft‐Knitted Engineering Textiles

Advanced Engineering Materials, EarlyView.
Textile‐integrated sensor architectures are systematically compared to evaluate their electromechanical behavior under combined mechanical and environmental loading. Pocket‐based integration exhibits stable and reproducible signals, whereas tunnel‐based routing shows higher sensitivity accompanied by increased variability.

The number and distribution of polar bears in the western Barents Sea

, 2017
Polar bears have experienced a rapid loss of sea-ice habitat in the Barents Sea. Monitoring this subpopulation focuses on the effects on polar bear demography.

Light and productivity of phytoplankton in polar marine ecosystems: a physiological view

, 1991
This study deals with the modeling of photosynthesis and growth of polar phytoplankton and variations in relevant parameters. Polar regions are characterised by low sun elevations (< 40?50°), extreme seasonal variations in irradiance and day length, and ...

Can we estimate the period and quality-factor of the Chandler wobble using only the observed polar motion data?

Earth, Planets and Space
The clear ~ 6-year beat in the polar motion data has allowed us to consider the Chandler period (P) as ~ 1.2 years, albeit approximately, from solely the observed polar motion data.
