Carbon Fibers from UV-Assisted Stabilization of Lignin-Based Precursors

open access: yesFibers, 2015
Production of high strength carbon fibers from bio-derived precursors is of topical interest. Recently, we reported on dry-spinning of a partially acetylated softwood kraft lignin to produce carbon fibers with superior properties, but the thermo ...

Metastatic niche shaped by host factors influences disseminated cancer cell fate

open access: yesFEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Prescribed fire placement matters more than increasing frequency and extent in a simulated Pacific Northwest landscape

open access: yesEcosphere
Prescribed fire has been increasingly promoted to reduce wildfire risk and restore fire‐adapted ecosystems. Yet, the complexities of forest ecosystem dynamics in response to disturbances, climate change, and drought stress, combined with myriad social ...

A Pathway to Reduce Energy Consumption in the Thermal Stabilization Process of Carbon Fiber Production

open access: yesEnergies, 2018
Process parameters, especially in the thermal stabilization of polyacrylonitrile (PAN) fibers, play a critical role in controlling the cost and properties of the resultant carbon fibers.

Vibrational Stabilization in Cyclacene Carbon Nanobelts [PDF]

open access: yesThe Journal of Physical Chemistry A
Cyclacene carbon nanobelts are predicted to be more stable in certain vibrational states. Vibrational simulations using hybrid thermally assisted-occupation density functional theory (TAO-DFT) predict small but consistent singlet-triplet electronic excitation energy changes at the classical harmonic vibrational turning points of the smaller belts ...

Performance of Soil Stabilized with Carbon Nanomaterials

open access: yesChemical Engineering Transactions, 2018
The use of nanomaterials to stabilize soil is a developing research area in geotechnical engineering. In this study, the use of carbon nanotube was compared to carbon nanofiber for possible applications in soil stabilization. Fundamental properties such as Atterberg’s limits and compaction characteristics were first explored.

Smaller is better: nanobodies meet NMR

open access: yesFEBS Letters, EarlyView.
Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.

Contrasting Pre- and Post-Pyrolysis Incorporation of Bentonite into Manure Biochar: Impacts on Nutrient Availability, Carbon Stability, and Physicochemical Properties

open access: yesAgronomy
Manure-derived biochar is a promising soil amendment, though its effectiveness is often constrained by limited structural stability and inconsistent nutrient retention. This study evaluated how the pyrolysis method (pre- vs. post-pyrolysis) and rate (5%,

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

open access: yesFEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?
