Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

Advanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

The practice of the zircon typomorphism studies using IR microscopy as applied to forecasting and prospecting for base and precious metals deposits

Руды и металлы
A potential effectiveness of IR microscopy in application to forecasting and prospecting for base and precious metals deposits is demonstrated on examples of studying zircon crystals collected at the Mechiveem area (Okhotsk-Chukotka volcanoplutonic belt),

Density Functional Study of a Helical Organic Cation

CHIMIA, 2003
We report on the first stage of our theoretical study of the quino[2,3,4-kl]acridinium,1,13-dimethoxy-5,9-dipropyl-cation. This molecule, involved in the synthesis of novel triazaangulenium dyes of high chemical stability, is a chiral [4 ...

Spread spectrum techniques for indoor wireless IR communications [PDF]

IEEE Wireless Communications, 2003
Multipath dispersion and fluorescent light\ud interference are two major problems in indoor\ud wireless infrared communications systems. Multipath\ud dispersion introduces intersymhol interference\ud at data rates above 10 Mb/s, while\ud fluorescent light induces severe narrowband\ud interference to baseband modulation schemes\ud commonly used such as ...

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.

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

Advanced 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 ...

Mass spectrum of gapped, non-confining theories with multi-scale dynamics

Journal of High Energy Physics, 2019
We study the mass spectrum of spin-0 and spin-2 composite states in a one-parameter family of three-dimensional field theories by making use of their dual descriptions in terms of supergravity.

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,

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

Results 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)
