Small, EarlyView.Four‐dimensional STEM comprises a vast portfolio of electron microscopy methods in one data set, conventional plane‐wave illumination TEM being one of them. Here, the principle of reciprocity is employed to produce true structural projections of misoriented ferroelectric domains at atomic resolution. By reciprocal TEM imaging from four‐dimensional STEM

A polynomial algebraic approach to Lyapunov stability analysis of higher-order 2D systems
, 2010 We introduce a four-variable polynomial matrix equation which plays an essential role in the stability analysis of discrete 2-D systems and in the computation of Lyapunov functions for such systems; we call this the 2-D polynomial Lyapunov equation (2-D ...

Colloidal Behavior of Carbonate Particles Microbially Precipitated in Microfluidic Droplets
Small, EarlyView.In Microbially Induced Calcium Carbonate Precipitation (MICP), ureolytic bacteria trigger calcium carbonate precipitation via pH‐increasing urea hydrolysis. This enzymatically driven reaction induces the colloidal assembly of bacteria and carbonate particles into fractal networks.

Small Methods, EarlyView.For the observation of micromechanical devices, a fast imaging technique with high temporal resolution is needed. Here, we demonstrate that a standard scanning electron microscope can be converted into a time‐resolving instrument using a fast detector and a time‐to‐digital converter.

Polynomial‐shaped electrodes for adaptive X‐ray optics
Journal of Synchrotron Radiation, EarlyView.A shaped electrode design for lithium niobate adaptive X‐ray mirrors connects actuator degrees of freedom to specific polynomial orders, enabling general shape control and the correction of defocus, coma and fourth‐order aberrations with a limited number of inputs.For adaptive mirrors on X‐ray beamlines and optical systems, we describe a strategy for ...

High‐purity X‐ray polarimetry at high energies for Mössbauer spectroscopy
Journal of Synchrotron Radiation, EarlyView.This work extends high‐purity X‐ray polarimetry into the 15–30 keV range, enabling polarization‐filtered synchrotron Mössbauer spectroscopy of higher‐energy nuclear resonances. A proof‐of‐principle experiment at 22.494 keV demonstrates a polarization purity of (1.2 ± 0.5) × 10−8, establishing the feasibility of the approach.High‐purity X‐ray ...

Allergy, EarlyView.We compared Finnish and Russian Karelian adolescents with contrasting allergy burden using integrated proteomic, metabolomic, and transcriptomic profiling. Finnish adolescents showed a broader pro‐inflammatory PBMC secretory profile consistent with a low‐grade inflammatory phenotype.
