Advanced Functional Materials, EarlyView.Gate bias is used to cancel Duffing nonlinearity in atomically thin MoS2 drumhead resonators, switching their response from hardening to softening and creating a nearly linear operating point. This electrical control suppresses hysteresis, enables stronger linear drive, and improves signal‐to‐noise ratio, offering a practical route to stable 2D NEMS ...

Barium Titanate BaTiO3 Raman Spectra and their deconvolution with q-BWF functions [PDF]
Here we study the Raman spectra of Barium Titanate, BaTiO3, given in the RRUFF and ROD databases. Being the Raman bands strongly asymmetric, we are deconvoluting them by means of the q-BWF functions. These functions are generalizing the Breit-Wigner-Fano

Gaining Quantitative Fidelity from Raman Spectra in Regimes of Large and Varying Fluorescence
Applied Spectroscopy PracticaRaman spectroscopy is attractive for probing complex mixtures, but in many real samples strong fluorescence overwhelms the Raman bands needed for quantitative analysis.

Effect of Optical Illumination on Bubble Nanodomains
Advanced Functional Materials, EarlyView.Stable surface‐confined nanoscale bubble domains are created and manipulated in PMN‐PT single crystals. Under above‐bandgap illumination, these bubble nanodomains remain unchanged. However, upon illumination cessation, they rapidly expand to switch the entire crystal surface, due to the accumulation of a large reservoir of electrons at the crystal ...

Raman Spectroscopy of Biological Tissue for Application in Optical Diagnosis of Malignancy [PDF]
, 2010 The use of Raman spectroscopy in the detection and classification of malignancy within the human larynx and lymph nodes of the head and neck has been evaluated. Currently histopathology is considered the diagnostic gold standard.

Identiï¬cation of mono- and few-layers graphene: Raman study
Materials and Devices, 2018 In this theoretical work, the Raman spectra were analyzed by considering the origin of the G peak, its shape, position and relative intensity as a function of the number of graphene layers.

Interface Engineering via Sb2Te3 Deposition Enables High‐Performance SWCNT Film Thermoelectrics
Advanced Functional Materials, EarlyView.SWCNTs are promising for flexible thermoelectrics but suffer from low performance. Here, cold‐pressed SWCNT films combined with deposited Sb2Te3 form engineered interfaces that enhance charge transport and energy filtering. The composite achieves a high power factor (25.82 µW cm−1 K−2) and delivers a power density of 3 mW cm−2 at ΔT = 40 K, with ...

Applications of Raman spectroscopy to urology [PDF]
, 2006 Raman spectroscopy is an optical technique that can interrogate biological tissues. In doing so it gives us an understanding of the changes in the molecular structure that are associated with disease development.

Advanced Functional Materials, EarlyView.The intrinsic distortion‐rich lattice of HEPBA with GQD‐enabled microstrain engineering establishes a mechanistic route toward high‐performance alkaline hydrogen evolution reaction. HEPBA inherently feature heterogeneous local coordination environments arising from multimetal incorporation, while properly introducing GQD during coprecipitation ...
