Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation

open access: yesAdvanced Materials, EarlyView.
Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.

Heterophase fcc‐hcp‐fcc High‐Entropy Alloy Nanomaterials with Tailored Electron Divergence for Selective Ammonia Electrosynthesis

open access: yesAdvanced Materials, EarlyView.
Heterophase fcc‐hcp‐fcc RuFeMMnMo (M═CoNi, Co, and Ni) high‐entropy alloy nanomaterials have been successfully synthesized using a one‐pot approach. The highly random distribution of multiple metal components and the tunable diversity of metal atomic arrangements can be realized simultaneously. By combining metals with different work functions, fcc‐hcp‐

Optimizing Nursery Production of Apple Trees: Assessing the Dose Response to Water and Fertilizer in Two Cultivars

open access: yesHorticulturae
This study examined the effects of two apple cultivars (Gala and Jonagold), four irrigation levels (0, 10, 20, and 30 mm), and four fertilization treatments (N0P0K0, N8P8K8, N16P16K16, N24P24K24) on nursery tree density.

Clay Reimagined: Phyllosilicates as Future Membrane Technologies

open access: yesAdvanced Materials Interfaces, EarlyView.
Recent advancements in membrane technologies based on 2D materials have drawn attention for molecular‐scale separations owing to these materials’ tunable nanoscale interlayer properties. Phyllosilicates, natural and abundant layered clay minerals, have emerged as scalable and cost‐effective candidates.

Effect of fertilisation timing on the partitioning of foliar‐applied nitrogen in Vitis vinifera cv. Chasselas: a 15N labelling approach

open access: yes, 2015
Background and Aims Yeast assimilable nitrogen (YAN) in grape must is an important determinant of wine composition. The effect of foliar nitrogen fertilisation on YAN concentration in must of Vitis vinifera L. cv. Chasselas was studied.
