Physical Properties of the K0.5Na0.5NbO3 Compound Doped With Li, La, and Ti in Concentration Lower Than 1.3 mol%

International Journal of Ceramic Engineering & Science
Physical properties of the K0.5Na0.5NbO3 (KNN) system doped with less than 1.3 mol% of Li+, La3+, and Ti4+ ions were studied. These samples were prepared by a mixture of oxides and carbonates using high‐energy milling and solid‐state reactions.

Dual‐Laser Laser‐Induced Liquid Bead Ion Desorption Mass Spectrometry: A New Approach for Adjustable Softness and Higher Sensitivity

ChemPhysChem, Volume 27, Issue 14, 29 July 2026.
Native protein complexes often require gentle ionization to preserve weak interactions, yet higher ion yield typically goes hand in hand with increased in‐source dissociation. Our dual‐laser LILBID approach decouples ion production from dissociation by using two independently tunable pulses, enabling sample‐specific soft conditions and expanding access

Spectroscopic Investigation of the In Vivo Light‐Dependent Photodynamics of the Marine Diatom Phaeodactylum tricornutum

ChemPhysChem, Volume 27, Issue 13, 14 July 2026.
µm fourier transform infrared (FTIR) image, 442 nm Raman of the Si–O of the silica‐based frustule at 472 cm−1, and UV–vis of Phaeodactylum tricornutum cells. Marine diatoms are responsible for fixing CO2 into organic carbon and contribute to the regulation of global climate.

Portable Breathing Monitoring With Phase‐Resolved Airflow Dynamics Enabled by a Dual‐Response Flexible PZT Sensor

Advanced Healthcare Materials, Volume 15, Issue 25, 3 July 2026.
A portable respiratory monitoring device based on a flexible PZT sensor captures pressure‐ and temperature‐related airflow responses in a single waveform. Polarity‐opposed piezoelectric and pyroelectric components generate a narrow transient spike and a broad quasi‐steady peak during both inhalation and exhalation. This dual‐component structure enables

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, Volume 11, Issue 13, 8 July 2026.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Embedded Direct‐Written Organic Micro‐TEGs for High‐Efficiency Skin‐Heat Harvesting

Advanced Electronic Materials, Volume 12, Issue 13, 6 July 2026.
A finite‐element–guided design of direct‐written organic micro‐thermoelectric generators is presented for efficient skin‐heat harvesting. Embedding PEDOT:PSS/PBFDO thermoelectric legs within flexible substrates suppresses interfacial heat losses and enhances vertical heat flow.

Breaking Inversion Symmetry via Vanadium Coordination Engineering in Bismuth Vanadium Selenites

Small, Volume 22, Issue 40, 17 July 2026.
Vanadium coordination engineering induces symmetry breaking in bismuth selenites by transforming symmetry‐compensated VO6/VO5F units into directionally aligned VO5 polyhedra. The resulting non‐antiparallel vanadyl arrangement eliminates dipole cancellation and stabilizes a polar noncentrosymmetric framework with nonlinear optical activity.
