Dataset on vibrational spectra of amber and amber-like resins

Data in Brief
The article presents experimental data on vibrational spectroscopy of worldwide amber and amber-like resins. IR spectra were obtained using SHIMADZU IRPrestige-2 (Japan). Raman spectra were obtained using a Virsa Raman analyzer (UK).

Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

Advanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Vibrational and surface-enhanced Raman spectra of vanillic acid [PDF]

, 2008
The 3-methoxy-4-hydroxybenzoic acid or vanillic acid (VA) is a naturally occurring molecule important in winemaking. The spectral fingerprints of VA observed in the infrared and Raman spectra are assigned to fundamental vibrational wavenumbers supported ...

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

Advanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...

Preparation method of tungsten oxide and metallic tungsten nano-powders using degreased cotton

Physical Sciences and Technology, 2018
A simple method for producing nanopowders of tungsten oxides and metallic tungsten using degreased cotton is proposed. Ammonium tungstate NH4W12O40 was used as a precursor. A medical cotton wool was chosen for experiment. Structural characterizations of

Spatially Regulated Lithium Plating via Li2O‐Rich Interphase Enables Durable Fast‐Charging Hybrid Lithium Batteries

Advanced Functional Materials, EarlyView.
A Li2O‐rich solid electrolyte interphase (SEI) is engineered on graphite through a propylene carbonate‐based electrolyte to spatially regulate Li plating. The homogeneous interphase lowers Li nucleation barriers, promotes conformal Li deposition around graphite particles, and suppresses dendritic accumulation, enabling durable hybrid Li‐ion/Li‐metal ...

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

Light‐Induced Field‐Tunneling Synapses in Solution‐Processed Van Der Waals Heterostructures for Scalable, Retina‐Inspired Optical Sensing

Advanced Functional Materials, EarlyView.
A scalable, solution‐processed WSe2/ZrO2‐x van der Waals heterostructure realizes a light‐induced field‐tunneling synapse (LIFTS) that activates exclusively under bright illumination, emulating the photopic adaptation of the human retina at the device level.
