COMPUTER SIMULATION OF STRUCTURAL FRAGMENTS OF COAL ORGANIC MASS

Вестник Кемеровского государственного университета, 2014
Hybrid B3LYP and gradient SLYP functionals were used to reveal the structure of organic mass of coal within the density functional theory in the basis of local orbitals. For all modeled compounds a number of important characteristics was identified – the

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)

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

Journal 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)

A natural little hierarchy for RS from accidental SUSY

, 2011
We use supersymmetry to address the little hierarchy problem in Randall-Sundrum models by naturally generating a hierarchy between the IR scale and the electroweak scale.

Modulating Two‐Photon Absorption in a Pyrene‐Based MOF Series: An In‐Depth Investigation of Structure–Property Relationships

Advanced Functional Materials, EarlyView.
This study investigates H4TBAPy‐based metal–organic frameworks (MOFs) ‐ NU‐1000, NU‐901, SrTBAPy, and BaTBAPy ‐ for multiphoton absorption (MPA) performance. It observes topology‐dependent variations in the 2PA cross‐section, with BaTBAPy exhibiting the highest activity.

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Mesonic Spectrum from a Dynamical Gravity/Gauge model

, 2010
Within a formulation of a Dynamical AdS/QCD model we calculate the spectrum of light flavored mesons. The background fields of the model correspond to an IR deformed Anti de Sitter metric coupled to a dilaton field.

Near‐Infrared Emitting Lanthanide Catecholate Giant Single Crystals – Morphology Control and Photon Down‐Conversion

Advanced Functional Materials, EarlyView.
Controlled syntheses of lanthanide coordination polymers based on the dihydroxybenzoquinone (DHBQ) organic linker afforded large single crystals of Ln‐DHBQ CPs (Ln = Yb, Nd). A novel structural variant of Yb‐DHBQ is identified by means of single crystal diffraction analysis.
