3D Closed‐Loop Navigation of Magnetic Microswimmers Using Vision‐Derived Depth Feedback

Advanced Intelligent Systems, EarlyView.
A planar magnetic microswimmer is navigated in three dimensions under a standard microscope. Image defocus supplies a real‐time depth cue, and model‐predictive control with A* planning steers the body on surfaces and in free swimming. Axial position is regulated by propulsion alone, without magnetic field gradients or extra cameras.

Functional Specialization of Respiratory and Olfactory Mucus Revealed by Proteomic Profiling

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Mucus overlies the nasal mucosa in the respiratory and olfactory regions, which perform distinct physiological functions. However, proteomic differences between respiratory mucosa (RM) and olfactory cleft (OC) mucus remain unclear.

Influence of Direct Saponification Conditions on Sterol Yield and Composition of the Unsaponifiable Fraction of the Microalga Isochrysis galbana and the Seaweed Ascophyllum nodosum

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Saponification is a key step for recovering the unsaponifiable fraction (USF) of lipids, which contains bioactive sterols, tocopherols, and carotenoids. This study optimized direct saponification conditions (50–300 g L−1 KOH; 60°C–100°C) to recover sterol‐rich USFs from the microalga Isochrysis galbana and the brown seaweed Ascophyllum nodosum,

Tailor‐Made 3D‐Nanoprinted Microchannel Plate Detector Functionalized by Atomic Layer Deposition Showing Electron Multiplication

Advanced Physics Research, EarlyView.
Development of a workflow for the fabrication of 3D‐nanoprinted microchannel plates using direct laser writing by two‐photon polymerization in combination with subsequent functionalization by atomic layer deposition. In a proof‐of‐concept experiment, the 3D‐nanoprinted microchannel plate is applied as a field emission current detector using carbon ...

SEARCHES FOR DARK MATTER AT THE LHC

, 2019
Astrophysical measurements show that around 85\% of the universe consists of dark matter, the origin of which is unknown. Dedicated experiments search for dark matter in the cosmos interacting directly and through annihilation.

Valorization of bark extracts from Cerrado and Amazon species: phenolic characterization, antioxidant capacity, and photoprotective potential for circular bioeconomy applications

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Tree bark remains an underexploited source of high‐value‐added phenolic compounds with potential circular bioeconomy applications. This work characterized bark extracts from two species of distinct Brazilian biomes, Stryphnodendron adstringens (Cerrado) and Myrcia eximia (Amazon), obtained with three solvents (ethanol, methanol and acetone ...

Knowledge gaps and research directions in migration ecology for advancing the conservation of migratory songbirds

Biological Reviews, EarlyView.
ABSTRACT Understanding migration ecology is essential for effective conservation of migratory species. To achieve a comprehensive understanding of the ecology of migrating species, it is necessary to study how species react to the complex interplay of intrinsic and extrinsic conditions when optimizing their migratory journey in terms of survival ...
