Thermal damage analysis in tissue caused by electromagnetic radiation using space-time collocation method.

Over the past half-century, the usage of external heat sources in medical applications has increased substantially. Controlling heat damage is essential for ensuring the efficacy of the treatment. Living tissues are highly non-homogeneous; hence, it is important to take into account the effects of local non-equilibrium on their thermal behavior.

New bis[MoO] and [MoO(O)] compounds: An artificial enzyme with peroxidase activity against o-phenylenediamine and dopamine.

In this study, two binuclear dioxido- and oxidoperoxido molybdenum (VI) complexes, [{MoO}(L)(HO)] 1 and [{MoO(O)}(L)(HO)] 2, were synthesized. Complex 1 was obtained through a 1:2 reaction of ligand I with MoO(acac), while complex 2 was synthesized in situ by reacting MoO with HO in a 1:2 ratio. The structures and characteristics of the complexes were examined employing several techniques such as elemental (CHN) analysis, spectroscopy (FT-IR, UV-Vis, H, and CNMR), and thermal study (TGA).

New bis[-{MoO}] complexes with dihydrazone ligands: synthesis, characterization, theoretical investigation and their peroxidase mimicking activity.

Three binuclear dioxidomolybdenum complexes designated as [{MoO}(L)(HO)] 1, [{MoO}(L)(HO)] 2, and [{MoO}(L)(HO)] 3 with dihydrazone ligands, HLI, HLII, and HLIII, have been prepared by the process with ligands and MoO(acac) in a ratio of 1 : 2. Many analytical techniques have been used to describe these complexes, including elemental (CHN) analysis, spectroscopy (FT-IR, UV-vis, H, and CNMR), and TGA analysis. SC-XRD analysis has been employed to study the structures of these complexes 1a, 2a, and 3a revealing the octahedral geometry and the binding of one molybdenum atom to each side of azomethine nitrogen, enolate oxygen, and a phenolic oxygen atom.

Physico-chemical and biological treatment strategies for converting municipal wastewater and its residue to resources.

An increase in urbanization and industrialization has not only contributed to an improvement in the lifestyle of people, but it has also contributed to a surge in the generation of wastewater. To date, conventional physico-chemical and biological treatment methods are widely used for the treatment of wastewater. However, the efficient operation of these systems require substantial operation and maintenance costs, and the application of novel technologies for the treatment and disposal of sludge/residues.

A novel concept of Vertical Up-Flow Forward Osmosis reactor: Design, performance and evaluation.

Performance of the forward osmosis (FO) process is limited due to the decline in water flux and increase in reverse salt flux. In this study, a novel Vertical Up-Flow Forward Osmosis (VUF-FO) reactor was designed and evaluated for eight different contacting patterns of feed and draw agent (DA). The best contacting pattern was compared with the basic H-shape reactor.

Strain-induced band modulation and excellent stability, transport and optical properties of penta-MP (M = Ni, Pd, and Pt) monolayers.

First principle calculations utilizing density functional theory were carried out to investigate the electronic, transport and optical properties of penta-MP (M = Ni, Pd and Pt) monolayer compounds under applied uniaxial and biaxial tensile strains. With an optimum magnitude of applied strain, we found band gap transitions in penta-MP monolayers from zero/narrow to the semiconductor regime, wherein band gaps were noticed to be firmly dependent on the applied uniaxial and biaxial tensile strains. In this study, the PBE approach was used primarily to evaluate electronic properties, from where the identified architectures of penta-MP with maximum obtained bandgaps under respective optimum strains were assessed through the HSE06 method of calculation for better estimation of band gaps and optical properties.

2D BeP monolayer: investigation of electronic and optical properties by driven modulated strain.

Recently, the two-dimensional (2D) material beryllium diphosphide (BeP) has attracted significant attention for potential device applications due to its Dirac semimetal state, dynamic and thermal stability, and high carrier mobility. In this work, we investigated its electronic and optical properties under biaxial Lagrangian strain using density functional theory (DFT). Electronic band gaps and effective charge carrier mass were highly sensitive to the Lagrangian strain of BeP monolayer.

An insight into biomimetic 4D printing.

4D printed objects are indexed under additive manufacturing (AM) objects. The 4D printed materials are stimulus-responsive and have shape-changing features. However, the manufacturing of such objects is still a challenging task.

Phase change heat transfer during cryosurgery of lung cancer using hyperbolic heat conduction model.

The paper reports a numerical study of phase change heat transfer process in lung cancer undergoing cryosurgery. A two dimensional hyperbolic bio-heat model with non-ideal property of tissue, blood perfusion and metabolism is used to analyze the problem.
