Controllable growth of two‐dimensional molecular crystals for high‐performance hybrid heterostructure imaging device

open access: yesInfoMat, EarlyView.
Layer‐controlled two‐dimensional perylene‐derivative molecular crystals grow by van der Waals vapor‐phase epitaxy and show near‐unity photoluminescence quantum yields. In hybrid structures with TMDCs, the carrier relaxation can be tuned from charge transfer to Förster resonance energy transfer.

Tissue Clearing for Lymph Nodes: 3D Mapping of Nerves and the Immune Microenvironment

open access: yesiNew Medicine, EarlyView.
ABSTRACT Lymph nodes (LNs) are central hubs of adaptive immunity and key relay sites for metastatic tumour cells. However, conventional two‐dimensional histology samples only a small fraction of each node, potentially missing micrometastases and multifocal involvement while obscuring long‐range spatial relationships among tumour deposits, immune ...

A Pain in the Buttocks: Practice Article for Sonographically Imaging the Quadratus Femoris and Ischiofemoral Impingement

open access: yesJournal of Clinical Ultrasound, EarlyView.
Hip external rotation can cause compression of the quadratus femoris (QF) between the ischial tuberosity and lesser trochanter of the femur, resulting in pain in the buttock, hip, and groin which can radiate down the leg. Ultrasound imaging can demonstrate dynamic impingement of the QF, including symptom provocation.

Looking at Soil as It Is: Evolution of Microscopic Soil Characterization From Kubiëna to Artificial Intelligence

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
We provide a historic overview of microscopic soil structure characterization from its founding father, Walter Kubiëna, to several technical revolutions like automation, digitalization, and artificial intelligence. In addition to technical advancements, we explore how concepts and research questions have evolved in time.

Qualitative Analysis of Biogas by Raman Spectroscopy: Effect of Pressure on Major Components

open access: yesJournal of Raman Spectroscopy, EarlyView.
Raman spectra of major and selected minor biogas components were studied under pressures up to 100 bar. Pressure‐induced shifts and band broadening were quantified for methane, carbon dioxide, and nitrogen, while Raman spectra of ammonia and hydrogen sulfide are presented in the context of biogas quality monitoring.
