Bioinspired Smart Nanogels for Rapid Blue Laser‐Activated Hemostasis in Gastrointestinal Bleeding

open access: yesAdvanced Materials, EarlyView.
Waxberry‐inspired branched‐silica nanogel can swiftly stop bleeding upon blue laser endoscopy for gastrointestinal hemostasis in the esophagus, stomach, and duodenum of mini‐pigs. Abstract Gastrointestinal bleeding (GIB) is a critical condition that requires rapid and effective intervention.

Electronic Energy Singularities of Weakly H-bonded Ammonium Dimer [PDF]

open access: yesarXiv
Quantum and molecular mechanics based electronic energy studies of weak H-bonded ammonium dimer show distinctive feature in energy profile when computed by different QM methods contrast to MM methods. MM based MMFF and SYBYL methods show smoothly varying dihedral energy profile for torsion angle variation around weak N1-H5 held by H-bond strength of ...

Exploring DNA Functionalization Techniques for Silver Nanoparticles

open access: yesAdvanced Materials Interfaces, EarlyView.
This study evaluates four functionalization methods—salt‐aging, pH‐assisted, freezing‐directed, and microwave‐assisted—for attaching DNA strands to 20 nm silver nanoparticles (AgNPs). The resulting DNA‐AgNP conjugates are characterized and colloidal stability and DNA loading are assessed.

Enhanced Photoresponse in Intermingled WS2 and MoS2 Nanodiscs on Graphene Heterostructure Nanohybrids

open access: yesAdvanced Materials Interfaces, EarlyView.
Intermingled WS2 and MoS2 nanodiscs on graphene made using alternative coatings of MoS2 and WS2 to achieve optimal morphology and high concentration of the nanodiscs to enable localized surface plasmonic resonance for enhanced light absorption and photodetection. Comparing the three samples, the highest photoresponsivity is obtained on WMW‐NDs/graphene

Effect of combined nitrogen on symbiotic nitrogen fixation in pea plants [PDF]

open access: yes
The nitrogen-fixing activity of the symbiotic system of Pisum sativum with Rhizobium leguminosarum is adversely affected by combined nitrogen. Both ammonium chloride and potassium nitrate, when added to the roots, lower the nitrogenase activity ...
