Unlocking the Full Potential of MgAgSb by Unravelling the Interrelation of Phase Constitution and Thermoelectric Properties

open access: yesAdvanced Functional Materials, EarlyView.
Persistent secondary phases govern the performance of many thermoelectric materials, particularly of high performance MgAgSb. In this study advanced microstructural characterization for unequivocal phase identification combined with transport modeling and statistical analysis enabled the quantification of each phase's impact, revealing the most ...

Electrochemically Driven Tandem In‐Plane Reduction and FeCl3‐ Intercalation of Highly Crystalline Graphene Oxide Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a green processing route for high‐performance reduced graphene oxide (rGO) transparent conductive films (TCFs) using highly crystalline Brodie's GO. In‐plane electrochemical reduction forms rGO on insulating substrates without toxic reductants or heat. Subsequent FeCl₃ intercalation enhances conductivity, overcoming the transparency–

Matching optics for Gaussian beams [PDF]

open access: yes, 1991
A system of matching optics for Gaussian beams is described. The matching optics system is positioned between a light beam emitter (such as a laser) and the input optics of a second optics system whereby the output from the light beam emitter is ...

Unlock the Walnut: How a Pectin‐Rich Suture Tissue and Moisture‐Driven Crack Formation Induce Shell Splitting and Facilitate Seed Germination

open access: yesAdvanced Functional Materials, EarlyView.
Walnut seeds are enclosed in a remarkably strong shell made of sclerenchyma, separated by a pectin‐rich suture tissue. Different cell shapes and chemical composition of this tissue point to an opening mechanism, which is triggered by cyclic humidity changes.
