Shedding light on reaction mechanisms : structure determination of reactive intermediates and investigation of protein structural dynamics using 2D-IR spectroscopy

open access: yes, 2013
Detailed knowledge of reaction mechanisms is key to understanding chemical, biological, and biophysical processes. For many reasons, it is desirable to comprehend how a reaction proceeds and what influences the reaction rate and its products.

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

open access: yesAdvanced 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.

BEHAVIOUR OF IR REFLECTIVE DYES AND PIGMENTS ON DIFFERENT FATLIQUORED UPHOLSTERY LEATHERS [PDF]

open access: yesAnnals of the University of Oradea: Fascicle of Textiles, Leatherwork, 2021
IR Reflective dyes and pigments are designed to make absorption in the visible region of the electromagnetic spectrum like the standard dyes but to reflect the Infra-Red region of the spectrum as a difference; which enables the items dyed with them to ...

Polarizable Vanadium Dipoles Promote Water Dissociation on Vanadium‐Based Metal Organic Framework

open access: yesAdvanced Functional Materials, EarlyView.
The polarization of unpaired V 3d electrons weakens the H─O bond to improve water dissociation by the dual Vδ+:O─H and Pλ−:H─O coupling hydrogen bonds formation and relaxation. P@V‐MOF electrocatalyst shows low overpotentials (94 mV in acid, 178 mV in neutral, and 77 mV in alkaline solutions) with excellent stability for effective overall water ...

C-PCM study of solvent influence on the ground and excited state structures of borazanaphthalene

open access: yesResults in Chemistry
In this research, the borazanaphthalene molecule is optimized at the ground state (S0), first singlet (S1), and triplet (T1) excited states using the M062X/6-311G(d,p) level of theory. The excited states were determined by the time-dependent DFT (TD-DFT)

A novel and stable ultraviolet and infrared intensity sensor in impedance/capacitance modes fabricated from degraded CH3NH3PbI3-xClx perovskite materials

open access: yesJournal of Materials Research and Technology, 2020
The present situation of COVID-19 diverted our focus towards utilizing the degraded solar cells for sensor application, this will help in global energy harvesting. So, here is our successful effort to reuse already degraded solar cells as ultraviolet (UV)

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

open access: yesAdvanced 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,

What Nonlinear−IR Experiments Can Tell You about Water that the IR Spectrum Cannot

open access: yes, 2016
Frequently, the IR spectrum of water is used to characterize the structure and strength of the associated hydrogen bond network. Here, we use nonlinear−IR spectroscopy to investigate the dynamics of four aqueous systems that have very similar absorption ...
