COMPARISON BETWEEN ANALYTICAL PYROLYSIS AND NITROBENZENE OXIDATION FOR DETERMINATION OF SYRINGYL/GUAIACYL RATIO IN Eucalyptus spp. LIGNIN [PDF]

open access: yes, 2008
Pyrolysis-gas chromatography/mass spectrometry (Py-GC-MS) was applied to measure the lignin syringyl/guaiacyl (S/G) ratio in E. dunni, E. grandis, E. nitens, E. urograndis, and E. urophylla woods.

Two Material Properties from One Wavelength‐Orthogonal Photoresin Enabled by a Monochromatic Laser Integrated Stereolithographic Apparatus (Mono LISA)

open access: yesAdvanced Materials, Volume 37, Issue 13, April 2, 2025.
A single object with dual properties – degradable and non‐degradable – is fabricated in a single print simply by switching the printing colors. The advanced multi‐material printing is enabled by the combination of a fully wavelength‐orthogonal photoresin and a monochromatic tunable laser printer, paving the way for precise multi‐material ...

Mechanical Resonant Sensing of Spin Texture Dynamics in a 2D Antiferromagnet

open access: yesAdvanced Materials, EarlyView.
Detection of antiferromagnetic spin texture in a 2D magnetic crystal is achieved through nanomechanical resonators at radio frequencies. Sharp magnetic transitions that lead to abrupt changes in mechanical linear and nonlinear responses are assigned to antiferromagnetic domain motions.

Ancestral Protein‐Based Lighting

open access: yesAdvanced Materials, EarlyView.
The ancestral sequence reconstruction (ASR) method applied to a large dataset of modern fluorescent proteins (FPs) led to a bright ancestral‐like FP suitable for photon down‐conversion in bio‐hybrid light‐emitting diodes (Bio‐HLEDs). Abstract Protein‐optoelectronics is a paradigm toward eco‐designed and sustainable technologies.

All‐Heat Control of Magnetization Dynamics on Van der Waals Magnets

open access: yesAdvanced Materials, EarlyView.
Heat dissipation in nanomagnetic devices mediated by femtosecond laser excitation constitutes one of the pressing challenges toward energy‐efficient information communication technologies. Here it is shown that heat and magnetization play together to determine the ultrafast spin dynamics of van der Waals magnets across any substrates and magnet ...

Excretion of Cannabinoids in Urine after Ingestion of Cannabis Seed Oil [PDF]

open access: yes, 2017
Gas chromatographic-mass spectrometric (GC-MS) quantitation of 25 cannabis sed oils determined Δ9-tetrahydrocannabinol (THC) concentrations from 3 to 1500 µg/g oil.

Radical TADF: Quartet‐Derived Luminescence with Dark TEMPO

open access: yesAdvanced Materials, EarlyView.
A new class of luminescent organic quantum materials is introduced, formed by attaching a stable radical to TADF chromophores. Due to ferromagnetic exchange coupling, a high‐spin quartet state forms upon excitation, which can thermally access a bright state.
