Near‐Infrared Cocrystal Nanofluorophore with Enhanced Two‐Photon Absorption Cross Sections

Advanced Science, Volume 13, Issue 17, 23 March 2026.
In this study, organic cocrystal nanoparticles (BP4TC‐NPs) were prepared via a nanoprecipitation method using an amphiphilic surfactant. The resulting cocrystal nanoparticles exhibit exceptional nonlinear optical properties and bioimaging capabilities.

Non‐Starch Purple Sweet Potato Polysaccharide Ameliorates Lipopolysaccharides‐Induced Acute Colitis by Regulating Gut Function and Inactivating the NOD‐Like Receptor Protein 3 Signaling Pathway

Food Frontiers, Volume 7, Issue 2, March 2026.
Purple sweet potato polysaccharide (PSP) ameliorates lipopolysaccharide‐induced ulcerative colitis in mice through multiple coordinated mechanisms. Oral PSP administration dose‐dependently: (1) Modulates gut microbiota composition and increases short‐chain fatty acid levels; (2) strengthens intestinal barrier function; (3) attenuates systemic ...

Quantitative Correlation Between Charge Transfer and Two Photon Absorption in Phenanthridine‐TCNB Cocrystal

Information &Functional Materials, Volume 3, Issue 1, Page 35-46, March 2026.
A new molecular cocrystal shows D‐A alternative molecular stacking, cyan‐blue photoluminescence with lifetime of 19.76 ns, and two‐photon absorption enabled emission under laser excitation between 720 and 880 nm. Theoretical calculations reveal its static dipole moment of 2.84 D, CT character in the ground, S1, and S2 excited states, and the TPA ...

Selective Visualization of Type II Collagen Using Sum‐Frequency Generation (SFG)

Journal of Biophotonics, Volume 19, Issue 3, March 2026.
Polarization‐resolved sum‐frequency generation microscopy enables the label‐free registration of collagen Type II, while discriminating it from Type I. The technique further reveals that in elastic cartilage, collagen Type II is organized into small domains of aligned fibrils.

Applicability of Novel Laser Scanning Microscopy Techniques in Demonstrating Characteristic Features of Porokeratosis: In Vivo and Ex Vivo Investigation

JEADV Clinical Practice, Volume 5, Issue 1, Page 91-100, March 2026.
Porokeratoses, used here as an example of keratinization disorders, are marked by cornoid lamella and linked to skin cancer risk, making accurate diagnosis essential. This study compared conventional methods, dermoscopy, and histopathology, with advanced imaging using reflectance confocal microscopy (RCM) and multiphoton microscopy (MPM).

Molecular Engineering of Octathio[8]Circulenes with Superhalogens for Enhanced Optoelectronic Properties

Nano Select, Volume 7, Issue 3, March 2026.
ABSTRACT Sunflower‐like octathio[8]circulene (C16S8) has gained attention for its exceptional thermal and electronic properties. In this study, a superhalogen‐based doping strategy was employed to enhance its nonlinear optical (NLO) response, investigated through density functional theory (DFT) simulations.

NLO photon parton parametrization

, 2005
An NLO photon parton parametrization is presented based on the existing $F_2^ $ measurements from $e^+e^-$ data and the low-$x$ proton structure function from $ep$ interactions. Also included in the extraction of the NLO parton distribution functions are the dijets data coming from $ p \to j_1 + j_2 +X$.

Method 2 at NLO

, 2004
This note describes a theoretical study of Wbb and Wjj final states at the Tevatron using the NLO program MCFM. We extensively study the effect of NLO corrections with respect to variations of input parameters such as the minimum jet p_T and the choice of renormalization and factorization scales.
