Electrochemical Detection of Chloride Ions by Copper (II) Complex with Mixed Ligand of Oxindole Derivative and Dithiocarbamates Moiety

Applied Sciences, 2019
The present work describes the synthesis of a new copper (II) complex with bidentate ligands based on oxindole (indolin-2-one) derivatives, namely: 1H,1′H,1″H-[2,3′:2′,3″-terbenzo[b]pyrrol]-2″(3″H)-one (L1) and [sodium diethyldithiocarbamate (DTC)] (L2 ...

Impact of surface phenomena on direct bulk flexoelectric effect in finite samples

, 2015
In the framework of a continuum theory, it is shown that the direct flexoelectric response of a finite sample essentially depends on the surface polarization energy, even in the thermodynamic limit where the body size tends to infinity.

Vacuum Energy and Casimir Force in a Presence of Skin-depth Dependent Boundary Condition [PDF]

, 2000
The vacuum energy-momentum tensor (EMT) and the vacuum energy corresponding to massive scalar field on $\Re_{t}\times [0,l] \times \Re^{D-2}$ space-time with boundary condition involving a dimensional parameter ($\delta$) are found.

Mechanisms of parasite‐mediated disruption of brain vessels

FEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Dual rare earth-doped Pt–Sn/Al2O3 catalysts with synergistic Ce and Sm effects on high-efficiency aromatization and coke suppression in naphtha reforming

Scientific Reports
In the present study, the effect of rare earth (RE) metals of Ce and Sm on the naphtha reforming process catalyst, i.e., Pt-Sn/γ-Al2O3, is investigated.

Saddle-like topological surface states on the TT'X family of compounds (T, T' = Transition metal, X= Si, Ge)

, 2017
Topological nodal-line semimetals are exotic conductors that host symmetry-protected conducting nodal-lines in their bulk electronic spectrum and nontrivial drumhead states on the surface.

Surface energy and wettability of van der Waals structures. [PDF]

Nanoscale, 2015
The wetting behaviour of surfaces is believed to be affected by van der Waals (vdW) forces; however, there is no clear demonstration of this. With the isolation of two-dimensional vdW layered materials it is possible to test this hypothesis.

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

All-inorganic cesium lead iodide perovskite solar cells with stabilized efficiency beyond 15%

Nature Communications, 2018
Black phase cesium lead iodide perovskite is regarded as a promising candidate for solar cells, but it easily transits to undesired yellow phase. Herein, Wang et al. stabilized the black phase using molecular additives to achieve device efficiency beyond

Probing consequences of anion-dictated electrochemistry on the electrode/monolayer/electrolyte interfacial properties

Nature Communications, 2020
Conveying electrochemistry in terms of the electrode/electrolyte interfacial properties remains challenging. Here, the authors employ a surface-bound molecular probe and photoelectron spectroscopy to peer into the anion-dictated and potential-induced ...
