Fluorinated Graphene‐Coated N95 Respirators for Enhanced Protection against Viral Accumulation and Transmission

Advanced Engineering Materials, EarlyView.
We develop a one‐step spray coating approach to coat the fluorinated graphene (FG) nanosheet onto the N95 respirators. The spray‐coated superhydrophobic N95 respirators can effectively repel respiratory droplets off instantaneously and prevent SARS‐CoV‐2 virus accumulation on the surface.

FTIR spectroscopy of nanodiamonds: Methods and interpretation

Diamond and Related Materials, 2018
Abstract Fourier transform infrared spectroscopy (FTIR) is highly sensitive to the surface chemistry of nanodiamonds. In this review, we discuss the different FTIR methods available to characterize nanodiamonds and highlight their advantages and limitations.

Performance Comparison of Surface Sensitizers for Diode Laser Powder Bed Fusion of Polyamide 12

Advanced Engineering Materials, EarlyView.
Laser‐generated nanoparticles transform standard PA12 powders into high‐performance, dye‐free feedstocks for diode laser 3D printing. Despite identical absorbance at 808 nm, CuS, LaB6, and CB coatings reveal striking differences in fusion and strength—unlocking new design space for recyclable, industrial‐grade polymers.

Botanical Authentication of “Espinheira-Santa” [Monteverdia ilicifolia (Mart. ex Reissek) Biral] Samples by FTIR Spectroscopy Coupled with PCA and Photoacoustic Spectroscopy

Brazilian Archives of Biology and Technology, 2023
Monteverdia ilicifolia (Mart. ex Reissek) Biral (basionym: Maytenus ilicifolia Mart. ex Reissek) (Celastraceae) is popularly known as holy thorn or “espinheira-santa” in Brazil. This herb is traditionally used for gastric and digestive problems. However,

Enhancing the sensitivity of nano-FTIR spectroscopy

Optics Express, 2017
Synchrotron radiation-based nano-FTIR spectroscopy utilizes the highly brilliant and ultra-broadband infrared (IR) radiation provided by electron storage rings for the infrared spectroscopic characterization of samples at the nanoscale. In order to exploit the full potential of this approach we investigated the influence of the properties of the ...

FTIR Spectroscopy of the Regulated Asbestos Amphiboles [PDF]

, 2018
Vibrational spectroscopies (FTIR, Raman) are exceptionally valuable tools for the identification and crystal-chemical study of fibrous minerals, and asbestos amphiboles in particular. Raman spectroscopy has been widely applied in toxicological studies and thus a large corpus of reference data on regulated species is found in the literature.

Real‐Time Characterization of Polypropylene Jet Dynamics in Melt Electrospinning Using Laser Diffraction and Image Analysis

Advanced Engineering Materials, EarlyView.
This study uses real‐time laser diffraction image analysis to quantify fiber diameter changes and whipping behavior from the nozzle to the collector under varying electric field conditions. By capturing diffraction (scattering) intensity changes and bending angles, melt jet and whipping behavior are accurately assessed, supporting melt electrospinning ...

Synthesis of microporous silica nanoparticles to study water phase transitions by vibrational spectroscopy [PDF]

, 2019
Silica can take many forms, and its interaction with water can change dramatically at the interface. Silica based systems offer a rich tapestry to probe the confinement of water as size and volume can be controlled by various templating strategies and ...

FTIR-Spectroscopy of Multistranded Coiled Coil Proteins [PDF]

Biochemistry, 1999
Coiled coils of different order were investigated using infrared (IR) spectroscopy. Recently, we demonstrated that dimeric coiled coils display unique vibrational spectra with at least three separable bands instead of only one band of a classical alpha-helix in the amide I region.
