Shaping Matter with Acoustic Waves: From Particles to Functional Structures
Advanced Functional Materials, EarlyView.Acoustic‐directed assembly is reviewed as a materials‐oriented strategy for organizing particles, polymers, metals, and biological systems into functional structures. The review distinguishes reversible manipulation from permanent structure formation through medium fixation, particle fixation, and in situ material generation, highlighting routes toward

ELECTROMAGNETIC RADIATION HAZARDS ON ECOLOGY
, 2020 The energy supplied to a human is food water and air, all these are polluted in today’s life, and at most the energy content or the supplements that carry vitamins and proteins are plants and their grains.

Advanced Functional Materials, EarlyView.All‐solution‐processed, low‐cost extended short‐wavelength infrared photodetectors are realized by coupling colloidal HgTe quantum dots to plasmonic In2O3:Sn,F nanocrystals. Localized surface plasmon resonances boost and spectrally tailor light absorption between 1500 and 3000 nm, enabling responsivities above 40 A W−1.

Log-moment estimators of the Nakagami-lognormal distribution
EURASIP Journal on Wireless Communications and Networking, 2019 In this paper, estimators of the Nakagami-lognormal (NL) distribution based on the method of log-moments have been derived and thoroughly analyzed. Unlike maximum likelihood (ML) estimators, the log-moment estimators of the NL distribution are obtained ...
