Vorticity‐Driven µ‐Platelet Rotation and Selective Packing for Vertical Thermal–Electrical Interconnects

Advanced Functional Materials, EarlyView.
We introduce a capillary‐filtering‐based particle‐filling (CFPF) process that simultaneously forms vertical thermal pathways and electrical vias within µ‐pores. In situ microfluidic analysis reveals that capillary‐driven velocity gradients generate vorticity that governs µ‐platelet rotation and vertical alignment.

Cytocompatibility of implants coated with titanium nitride and zirconium nitride

Bratislava Medical Journal, 2015
The positive cell response to the implant material is reflected by the capacity of cells to divide, which leads to the tissue regeneration and osseointegration. Technically pure titanium and its alloys are mostly used for implant manufacturing. These alloys have the adequate mechanical, physical and biological properties; nevertheless, the superior ...

Erosion Corrosion Evaluation of CrN/AlN Multilayer Coatings, by Varying the Velocity and Impact Angle of the Particle

International Journal of Electrochemical Science, 2013
In order to provide solutions to erosion corrosion in industrial devices, thin films of CrN/AlN were deposited on AISI D3 steel substrates using a magnetron sputtering system multitarget with rf (13.56 MHz), from Al and Cr targets of high purity (99.99%)

Is It Real Type‐II or S‐Scheme? A Three‐Phase Diagnostic Protocol for Identifying Potentially Mislabeled Heterojunction Photocatalysts

Advanced Functional Materials, EarlyView.
Diagnostic analysis via the heterojunction validation funnel. The funnel illustrates the hierarchical stratification of 30 reported Type‐II systems based on the three‐phase, seven‐step diagnostic framework. Complete validation through all phases is achieved by only 3.3% of systems, while 96.7% lack full mechanistic validation, revealing a pervasive ...

Zeeman splittings of the 5D0–7F2 transitions of Eu3+ ions implanted into GaN

, 2011
We report the magnetic field splittings of emission lines assigned to the 5D0–7F2 transitions of Eu3+ centres in GaN. The application of a magnetic field in the c-axis direction (B||c) leads to a splitting of the major lines at 621 nm, 622 nm and 622.8 ...

Sustainable Electrochemical Synthesis of High‐Quality MXenes: Mechanistic Insights, Applications, Challenges, and Technological Prospects

Advanced Functional Materials, EarlyView.
Electrochemical etching provides an eco‐friendly alternative to hazardous HF methods for MXene production. This approach facilitates the selective isolation of the A‐layer from MAX phases with tunable surface terminations. Controlling voltage, electrolytes, temperature, and duration enables the optimal structural integrity. Nevertheless, existing scale

Proximity Ferroelectricity in Compositionally Graded Structures

Advanced Electronic Materials
Proximity ferroelectricity is a novel paradigm for inducing ferroelectricity in a non‐ferroelectric polar material, such as AlN or ZnO that are typically unswitchable with an external field below their dielectric breakdown field.
