Copper Nanocrystallization in Anodic Oxide Films of Ti–Cu‐Based Bulk Metallic Glass and Its Effect on the Corrosion Resistance and Cytocompatibility

Advanced Engineering Materials, EarlyView.
Viktoriia Shtefan, Thorgund Nemec, Ute Hempel, Annett Gebert and coworkers demonstrate that anodic treatment of Ti–Cu‐based metallic glass in a nontoxic pyrophosphate electrolyte forms a protective bilayered Ti/Zr‐oxide film enriched with Cu nanocrystals.

Effects of foliar spraying with amino acid and potassium fertilizers on the yield and quality of Anji white tea

浙江大学学报. 农业与生命科学版
Cold injury in early spring is one of the main harmful factors affecting the production of spring tea. It is of practical significance to improve the cold resistance and early fresh leaf yield of tea plants by foliar fertilization.

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

Advanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Modulating Two‐Photon Absorption in a Pyrene‐Based MOF Series: An In‐Depth Investigation of Structure–Property Relationships

Advanced Functional Materials, EarlyView.
This study investigates H4TBAPy‐based metal–organic frameworks (MOFs) ‐ NU‐1000, NU‐901, SrTBAPy, and BaTBAPy ‐ for multiphoton absorption (MPA) performance. It observes topology‐dependent variations in the 2PA cross‐section, with BaTBAPy exhibiting the highest activity.

Feshbach resonances in potassium Bose-Bose mixtures

, 2018
We present a detailed study of the scattering properties of ultracold mixtures of bosonic potassium atoms. We locate 20 previously unobserved Feshbach resonances in isotopic 39K-41K mixtures.

Potassium Polyuranates

CHIMIA, 1969
A reinvestigation of the system K2O–UO3 by diffraction methods and i.r. spectroscopy shows that there are two well defined polyuranate phases. Both are based structurally on layers of uranium in hexagonal array, as found in U3O8 and K2U2O7. One polyuranate, isolated in crystalline form is of the diuranate type, with anionic layers 7.045 Å apart, the ...

Potassium and Hypertension [PDF]

Nutrition Reviews, 2009
A recent meta-analysis supports the premise that increased potassium intake may play a role in the prevention and treatment of hypertension. The possible mechanisms by which potassium may act as an antihypertensive and recommendations regarding increasing potassium intake are also discussed.

Highly Sensitive Electrochemical Biosensor Based on Hairy Particles with Controllable High Enzyme Loading and Activity

Advanced Functional Materials, EarlyView.
For the first time, a highly sensitive electrochemical biosensor based on SiO2‐based hairy particles with a grafted PDMAEMA polymer brush containing a quantifiable and large amount of immobilized Laccase is reported. The fabricated biosensor exhibits a sensitivity of 0.14 A·m⁻¹, a limit of detection (LOD) of 0.1 µm, and a detection range of 0.3–750 µm,
