Hydrogen bonding, spectroscopic (FT-IR and FT-Raman), UV−Vis, and Mulliken charge analysis of Guanosine-5′ -Diphosphate: insight from DFT and molecular docking

Bibechana
Hybrid functional B3LYP has been used for quantum chemical calculation of Guanosine-5′ -Diphosphate (GDP) from DFT approach. The intra-molecular hydrogen bonding in the title molecule was rendered from Quantum theory of atoms in molecule (QTAIM).

DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

Advanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Electron Beams Generated by the Electron Kelvin‐Helmholtz Instability at a Quasi‐Perpendicular Shock

Geophysical Research Letters
Electron beams are considered to be important free energy sources for the excitation of various plasma waves at quasi‐perpendicular shocks. In this article, we perform a two‐dimensional particle‐in‐cell simulation of a low‐plasma‐β quasi‐perpendicular ...

Strain‐Programmable Luminescent Adhesive Patch With Tartrazine‐Mediated Optical Skin Clearing for Photochemical Tissue Bonding

Advanced Functional Materials, EarlyView.
We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,

Fully Kinetic Simulations of Ion‐Acoustic Waves in Asymmetric Reconnection With Cold Ions

Geophysical Research Letters
In collisionless plasma, ion‐acoustic wave (IAW) is an important candidate for enhancing resistivity and viscosity, yet their presence and role in magnetic reconnection remain poorly understood.

Spectroscopic and theoretical evaluation of feruloyl derivatives: Insights into their electronic properties

Results in Chemistry
The spectroscopic characterization of ferulic acid (FA), ethyl ferulate (EF), 1-feruloyl-glycerol (FG), and 1,3-diferuloyl-glycerol (DFG) was done using absorbance spectrophotometry and fluorescence excitation-emission matrix (EEM) analysis.

Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

Advanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films

Advanced Functional Materials, EarlyView.
Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...

Regulated Ion‐Diffusion Hydrogels for Subtle and Multimodal Temperature‐Strain Sensing in Wound Monitoring

Advanced Functional Materials, EarlyView.
A soft, dual‐channel hydrogel patch enables simultaneous detection of wound temperature and strain by integrating ion‐diffusion‐mediated thermoelectric and resistive sensing. The conformal design maintains stable performance during motion, capturing subtle inflammatory and mechanical changes for continuous wound monitoring.
