Advanced Healthcare Materials, EarlyView.This review highlights recent advances in smart face masks that actively monitor breathing. By integrating humidity, gas, temperature, pressure, strain, and triboelectric sensors, these masks track key respiratory parameters in real time. The article summarizes sensor mechanisms, compares performance across studies, and discusses challenges and future ...

The reversing magnetic field of planet earth [PDF]
Proceedings of the 2011 companion on High Performance Computing Networking, Storage and Analysis Companion, 2011 The magnetic field generated in the fluid metallic core of planet Earth is shown. Numerical simulations of the dynamo mechanism, such as this one, exhibit polarity reversals, whereby the north pole moves by 180 degrees; this mimics the behavior documented many times within the geological record.Our simulation solves the equations of momentum transfer ...

Nanotherapies for Atherosclerosis: Targeting, Catalysis, and Energy Transduction
Advanced Healthcare Materials, EarlyView.Atherosclerosis management is hindered by poor drug targeting and plaque heterogeneity. Nanotechnology overcomes these barriers via three core strategies: (1) target‐engineered nanocarriers that achieve lesion‐specific precision via ligand modification, biomimetic camouflage, stimuli‐responsive release, and self‐propelling nanomotors; (2) catalytic ...

The characterization of diffusion tensor for mid-latitude ionospheric plasma
Annals of Geophysics, 2014 In this study, the relationship between diffusion and the electrical conductivity tensor is investigated by using the real geometry of the Earth’s magnetic field in the Northern Hemisphere for mid-latitudes.

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.

Magnetic declination of the territory of Ukraine: the results of observations and calculations
Геофизический журнал, 2015 A technology is proposed for calculating the strength and angular components of the vector of the induction of the Earth's magnetic field. The technology is based on the development of a three-dimensional model of the earth's crust and the calculation of

Advanced Materials, EarlyView.Magnetic doping of the topological insulator Bi2Te3 with erbium adatoms induces out‐of‐plane magnetism and breaks time‐reversal symmetry, opening a Dirac gap and driving a Fermi surface transition from hexagonal to star‐of‐David geometry. Microscopy, spectroscopy, and magnetic dichroism reveal atomically controlled magnetic interactions that tailor the
