NMR Spectroscopy in the Earth's Magnetic Field
Bitlis Eren Üniversitesi Fen Bilimleri Dergisi, 2023 Magnetic imaging systems used today are quite expensive and are generally used for medical purposes. Apart from this purpose, there are many scientific fields of study whose internal structure is desired to be displayed. Especially in science, different from the techniques used to understand the internal structure of matter, magnetic imaging techniques

Advanced Functional Materials, EarlyView.Methane photocatalytic activation under mild conditions remains a formidable challenge in the synthesis of solar fuels. In this review, we emphasize the growing importance of multifunctional materials and hybrid systems within a unified mechanistic framework that integrates selective C─H bond activation, formation and control of intermediates, C─C ...

Mineral Deposition From Liquid Precursors Triggered by Complementary Polyelectrolytes
Advanced Functional Materials, EarlyView.Polyelectrolyte additives can delay or prevent crystal nucleation in supersaturated solutions of insoluble mineral salts such as calcium carbonate. This work reports that adding a second, oppositely‐charged polyelectrolyte leads to immediate mineral crystallization from such metastable solutions.

DAILY VARIATION IN EARTH'S MAGNETIC FIELD
Rudarsko-geološko-naftni Zbornik, 2000 Daily variation in Earth's magnetic field is changed during the time of the day and according to Earth's latitude and lengthwise. Due to great sensitivity of new proton magnetometers there is a question how daily variation vary according to distance from

An Edible Chitosan‐Based Acoustic Sensor for Sound‐Responsive Actuation in Edible Robots
Advanced Functional Materials, EarlyView.This study introduces an edible acoustic sensor for robotic food and edible robotics. Built from a chitosan piezoelectric film between gold electrodes, the sensor enables acoustic communication through ON/OFF keying. Integrated into an edible robot with pneumatically actuated arms and neck, it responds to high‐frequency tones.

The effectiveness of polder systems on peak discharge capping of floods along the middle reaches of the Elbe River in Germany [PDF]
Hydrology and Earth System Sciences, 2007 In flood modelling, many one-dimensional (1-D) hydrodynamic models are too restricted in capturing the spatial differentiation of processes within a polder or system of polders and two-dimensional (2-D) models are very demanding in data requirements and ...

Advanced Functional Materials, EarlyView.Grain boundaries (GBs) in polycrystalline materials often block charge transport and drive degradation. Using Gd‐doped CeO2 as a model electrolyte used in fuel/electrolysis cells, we developed a core‐shell infiltration method to selectively modify GB chemistry and space charge potential, achieving orders‐of‐magnitude ionic conductivity changes.

Advanced Materials, EarlyView.The Y supersaturation in the [Ba‐Cu(I/II)‐O] transient liquid composition is the driving force toward YBCO nucleation and growth in TLAG. Tuning the initial (Ba:Cu) molar ratio in the ink composition determines the YBCO epitaxial nucleation through supersaturation control.

Spin and Charge Control of Topological End States in Chiral Graphene Nanoribbons on a 2D Ferromagnet
Advanced Materials, EarlyView.Chiral graphene nanoribbons on a ferromagnetic gadolinium‐gold surface alloy display tunable spin and charge states at their termini. Atomic work function variations and exchange fields enabe transitions between singlet, doublet, and triplet configurations.
