Advanced Functional Materials, EarlyView.Solvent‐composition‐controlled film formation enables high‐performance (efficiency = 18.66%) and air‐stable terpene‐processed organic solar cells. An optimized eucalyptol/tetralin ratio of 50:50 (v/v) balances molecular solvation and aggregation kinetics, producing favorable nanoscale phase separation and vertical composition gradients.

Advanced Functional Materials, EarlyView.Unlocking thermomagnetic low‐grade waste heat recovery. This perspective provides a comprehensive roadmap for the development of thermomagnetic materials and systems. By addressing key engineering challenges across multiple scales, it bridges the gap between micro‐power IoT devices and large‐scale industrial applications. ABSTRACT Nearly half of global

Advanced Functional Materials, EarlyView.Conversion‐induced sulfur expansion generates strong mechanical constraints and localized stresses within solid‐state Li‐S cathodes. Heterogeneous solid‐electrolyte confinement creates tensile strain‐energy hotspots that govern particle cracking. Larger sulfur particles accelerate fracture, while higher porosity relaxes constraint and delays damage ...

Advanced Functional Materials, EarlyView.Poly(acrylic acid) acts as a reaction‐time pH buffer during hydrothermal Sb2(S,Se)3 growth through its COOH/COO‐ equilibrium. When combined with ethanol‐regulated growth, this buffering strategy reduces Sb‐O related surface disorder, improves local electronic uniformity and carrier collection, and increases the champion solar‐cell efficiency to 10.25%,

Magneto‐Ionic Devices With Polymer‐Based Electrolytes
Advanced Functional Materials, EarlyView.Polymer electrolytes are introduced for magneto‐ionic devices based on hydroxide and hydrogen ions. The magneto‐ionic effect results in a pronounced voltage‐controlled variation of coercivity in both devices. The switching speed is in the range of 100 ms.

Only in a few European countries (Switzerland, France, Poland, Belgium, and some local projects in Germany) are minimally invasive breast biopsies (MIBB) reimbursed by health insurance. Public health authorities ask for detailed estimates and calculation of costs as well as laborious, expensive evaluation procedures as the basis for decision making ...

Given the state-of-the-art in ontological engineering, we still lack costing models for software projects that adopt reusable ontological libraries. However, we can find such costing models in the standard software engineering literature. The COCOMO-II software cost estimation model offers an estimate of the cost of adapting reusable sub-routines for a

There are not, and probably never will be, enough resources to satisfy the community's desires for things that improve the quality of life. This poses the necessity for choice, and hence the consideration of priorities. In the medical field two distinct kinds of choice arise: one at the clinical level and the other in the planning process. At the point

Cost Benefit Deployment of DNIPS
2010 IEEE International Conference on Communications, 2010Effective deployment of Real Time Distributed Network Intrusion Detection Systems (DNIDS) on High- speed and large-scale networks within limited budget constraints is a challenging task. In this paper we investigate algorithms aiming at optimizing the deployment of DNIDS systems.
