Reconfigurable Circularly Polarized Terahertz Emission from vdW Ferroelectric NbOI2

open access: yesLaser &Photonics Reviews, EarlyView.
A controllable chiral terahertz pulse can be generated using a simple dual‐flake vdW ferroelectric NbOI2 emitter in which the polar axes of the two NbOI2 flakes are orthogonal. Both the chirality and the ellipticity can be manipulated by varying the separation distance and the orientations of their polar axes.

Enhancing Crystallinity of Electrospun Polylactic Acid Fibers: Insights into Formation Mechanisms and Property Modulation–A Review

open access: yesMacromolecular Materials and Engineering, EarlyView.
Controlled processing, nucleating agents, and monitored post‐treatments improve electrospun PLA nanofiber crystallinity. Additionally, stereocomplexation of PLLA and PDLA further enhances this property. Together, these strategies enable scalable, sustainable fabrication of high‐performance PLA nanofibers, expanding their applicability across industrial,

Conductivity in Jurkat cell suspension after ultrashort electric pulsing

open access: yes, 2004
Ultrashort electric pulses applied to similar cell lines such as Jurkat and HL-60 cells can produce markedly different results , which have been documented extensively over the last few years.

Diacetylene‐Functionalized Glycan Mimetics for Receptor‐Mediated Cluster Imprinting in Model Membranes

open access: yesMacromolecular Rapid Communications, EarlyView.
Diacetylene‐containing glycan mimetics cluster upon selective lectin binding in GUVs. Subsequent irradiation leads to the formation of fluorescent polymer clusters, while non‐clustered glycan mimetics remain unaffected in the membrane. ABSTRACT The glycocalyx, a dense layer of glycoproteins and glycolipids on eukaryotic cells, is essential for cellular

Thermal desorption study of physical forces at the PTFE surface [PDF]

open access: yes
Thermal desorption spectroscopy (TDS) of the polytetrafluoroethylene (PTFE) surface was successfully employed to study the possibile role of physical forces in the enhancement of metal-PTFE adhesion by radiation.

Terahertz Spectroscopy in the Lab and at Telescopes [PDF]

open access: yes, 2009
The section of the electromagnetic spectrum extending roughly from wavelengths of 3 mm to 30 μm is commonly known as the far-infrared or TeraHertz (THz) region.

Mass Spectrometry Structural Proteomics Enabled by Limited Proteolysis and Cross‐Linking

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The exploration of protein structure and function stands at the forefront of life science and represents an ever‐expanding focus in the development of proteomics. As mass spectrometry (MS) offers readout of protein conformational changes at both the protein and peptide levels, MS‐based structural proteomics is making significant strides in the

Multi‐scale geophysical mapping of the brine and bedrock surfaces along the Dolores River, Paradox Valley, Colorado, December 2023

open access: yesNear Surface Geophysics, EarlyView.
Abstract Total dissolved solids derived from salt dome–sourced brine in the underlying alluvial aquifer substantially increase with distance in the reach of the Dolores River that passes through Paradox Valley in southwestern Colorado. The area has been the site of salinity control operations since the 1990s to reduce salt loading to the downstream ...

Salinity Effect in Permeability of Salt in Nanofiltration and Reverse Osmosis Membranes

open access: yesChemistryOpen, EarlyView.
This study assesses the effect of feed salinity (2–6 g L−1) on the performance of two nanofiltration membranes (NF270, NF90) and one reverse osmosis membrane (TM710). NF270 provides the highest permeate flux, while TM710 achieves the best TDS rejection. Increasing salinity reduces flux for all membranes.
