Snapping Graph Drawings to the Grid Optimally

, 2016
In geographic information systems and in the production of digital maps for small devices with restricted computational resources one often wants to round coordinates to a rougher grid.

Deformation Behavior of Optical Ceramic Nanomultilayers: The Role of Aperiodicity

Advanced Engineering Materials, EarlyView.
Ceramic nanomultilayers demonstrate optical and mechanical behavior tunability through aperiodicity. Within the studied systems, optically optimized coatings exhibit an average ultraviolet, visible, and near‐infrared spectral transmittance above 90%.

Minimum-weight triangulation is NP-hard [PDF]

, 2006
A triangulation of a planar point set S is a maximal plane straight-line graph with vertex set S. In the minimum-weight triangulation (MWT) problem, we are looking for a triangulation of a given point set that minimizes the sum of the edge lengths.

Encapsulating Laser‐Induced Graphene to Preserve its Electrical Properties and Enhance its Mechanical Robustness

Advanced Engineering Materials, EarlyView.
It is demonstrated that laser‐induced graphene (LIG) can be encapsulated while preserving its electrical conductivity and enhancing its mechanical properties. Unlike previous encapsulation attempts, the optimal conditions described here result in sheet resistance of ≈2 Ω sq−1, resistance increase of only 5% upon encapsulation, and vastly improved ...

Removing Homocoupling Defects in Alkoxy/Alkyl‐PBTTT Enhances Polymer:Fullerene Co‐Crystal Formation and Stability

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 ...

On Upward Drawings of Trees on a Given Grid

, 2017
Computing a minimum-area planar straight-line drawing of a graph is known to be NP-hard for planar graphs, even when restricted to outerplanar graphs. However, the complexity question is open for trees.

The Route to Artery Mimetics: Hybrid Bioinks for Embedded Bioprinting of Multimaterial Cylindrical Models

Advanced Functional Materials, EarlyView.
The fabrication of a cellularized, multilayered 3D printed cylindrical model comprising hybrid bioinks inspired by the natural extracellular environment as an approach to artery mimetics, is presented. Using embedded bioprinting, interlayer crosslinking of self‐supporting concentric cylinders is achieved.

Unique Performance Considerations for Printable Organic Semiconductor and Perovskite Radiation Detectors: Toward Consensus on Best Practice Evaluation

Advanced Functional Materials, EarlyView.
A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

Advanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...
