On the Identification of Rayon/Viscose as a Major Fraction of Microplastics in the Marine Environment: Discrimination between Natural and Manmade Cellulosic Fibers Using Fourier Transform Infrared Spectroscopy

open access: yesApplied Spectroscopy, 2016
This work was sparked by the reported identification of man-made cellulosic fibers (rayon/viscose) in the marine environment as a major fraction of plastic litter by Fourier transform infrared (FT-IR) transmission spectroscopy and library search.

High‐Performance Low‐Emissivity Paints Enabled by N‐Doped Poly(benzodifurandione) (n‐PBDF) for Energy‐Efficient Buildings

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces a scalable and colored low‐emissivity (low‐e) paint achieved by spraying an ultrathin n‐doped poly(benzodifurandione) (n‐PBDF) coating onto various colored substrates. The low‐e paint enhances thermal regulation by reducing mid‐infrared thermal emissivity to 0.19, thereby stabilizing indoor temperatures across diverse climates ...

Self‐Cascade Catalytic Reaction–Assisted Apoptosis/Calcicoptosis/Ferroptosis Induction with Microsphere‐Aggregated Hydrogels in Triple‐Negative Breast Cancer Therapy

open access: yesAdvanced Functional Materials, EarlyView.
Hyaluronic acid‐dopamine‐based intra‐crosslinked microsphere including cisplatin (HPC MS) is fabricated by spray‐drying and calcium/iron ions are introduced for interparticle crosslinking. Designed microsphere‐aggregated hydrogel (MAH) system including cisplatin/CaO2/FeSO4 can provide apoptosis/calcicoptosis/ferroptosis‐mediated chemo/cascade ...

In search of space: Fourier spectroscopy, 1950-1970 [PDF]

open access: yes, 2001
In the large grey area between science and technology, specialisms emerge with associated specialists. But some specialisms remain ‘peripheral sciences’, never attaining the status of disciplines ensconced in universities, and their specialists do not ...

Synthesis and Characterization of Mixed Methyl/Allyl Monolayers on Si(111) [PDF]

open access: yes, 2010
The formation of mixed methyl/allyl monolayers has been accomplished through a two-step halogenation/alkylation reaction on Si(111) surfaces. The total coverage of alkylated Si, the surface recombination velocities, and the degree of surface oxidation as

Multi‐Scaled Cellulosic Nanonetworks from Tunicates

open access: yesAdvanced Functional Materials, EarlyView.
Microbial and plant nanonetworks of cellulose have enabled a wide range of high‐performance yet sustainable materials. Herein, a third class of cellulosic nanonetworks is showcased by exploiting the only animal tissue‐producing cellulose nanofibers, i.e., ascidians. An ultrastructure including spherical cells and a microvasculature with diameters of 50–
