Thermoelectric devices integrated with optical resonance absorbers are demonstrated. We design the absorbers with rigorous numerical methods and fashion experimental prototypes by thin-film deposition, patterning, and etching. A ~2.5-μm-thick p-type heavily doped polysilicon film on a ~2-μm layer of thermally grown Si…
Protein alignments are commonly used to evaluate the similarity of protein residues, and the derived consensus sequence used for identifying functional units (e.g., domains). Traditional consensus-building models fail to account for interpositional dependencies - functionally required covariation of residues that tend…
This paper reports a physicochemical study (thermodynamic and kinetic data) describing the ability of Rubus ulmifolius biomass (dead leaves) for metal uptake. The toxicity of aluminum is a major problem for crops in acidic soils and therefore, aluminum has been selected. The results obtained indicate that dead R. ulmi…
The sonocatalytic degradation of organic dyes (C.I. 50040, C.I. Reactive Red 1, C.I. Acid Orange 7) catalysed by Co/N/Er3+ : Y3Al5O12/TiO2 films was studied. For the preparation of Co/N/Er3+ : Y3Al5O12/TiO2 films, the sol-gel coating process was used. The phase composition, morphology, precursor at different temperatu…
Abstract Kinetic investigations of cysteine–cystine transformation assisted by model electron acceptor methylene blue (MB) and catalyzed synergistically by Ru (III) and Cu (II) in aqueous media of varying pH, temperature and micellar solutions of two ammonium based cationic surfactants viz. octadecylammonium chloride…
Three coordination complexes with Cu(I) centres have been prepared using the symmetrical flexible organic ligands 1,3-bis{[5-(quinolin-2-yl)-1,3,4-oxadiazol-2-yl]sulfanyl}propane (L1) and 1,4-bis{[5-(quinolin-2-yl)-1,3,4-oxadiazol-2-yl]sulfanyl}butane (L2). Crystallization of L1 with Cu(SO3CF3)2 and of L2 with Cu(BF4)…
The monoanion of dihydrogenated corannulene isolated in the form of its potassium salt, namely tris(diglyme-κ(3)O,O',O'')potassium hexacyclo[11.5.2.0(4,17).0(7,16).0(10,15).0(14,18)]icosa-1,3,5,7(16),8,10(15),11,13,17-nonaenide, [K(C6H14O3)3](C20H12), has been structurally characterized for the first time. The X-ray s…
In this review, we comprehensively summarize the synthetic approach that can be developed for the design and the preparation of iron complex intercalated LDH structure which mainly involves oxalate, citrate, ferrocyanide, ferrocene, N,N’-ethylenebis(salycylideneiminato) (salen), porphyrine and proteins. Then, we propo…
A novel microreactor that allows for mixed, slurry-phase batch experiments to be conducted at temperatures to 445 °C and pressures of 13.8 MPa is reported. The reactor uses a glass insert to isolate the reaction mixture from the catalytically active reactor walls and a vortex mixer to promote gas–liquid–solid mixing a…
Microorganisms—organotrophs, which inhabit in the natural medium, negatively affect the industrial and economical metal constructions and initiate their corrosion damages. Corrosion of metals under the effect of bacteria—organotrophs—starts from their adhesion to the metal surface and formation of a biochemical struct…
Incorporation of organic functionalities within porous materials is a very elegant manner to control the administration of therapeutic drugs. Delayed drug-release profile originates from weak and reversible interactions (e.g., electrostatic, hydrophobic–hydrophobic and H-bonding interaction) between the modified carri…
Abstract A novel dendritic heteropolyacid (HPA)‐based ionic liquid has been prepared from the interaction between H3PW12O40 (HPW) and a multi‐SO3H dendritic ionic liquid (IL). This HPA IL exhibited strong Brønsted acidity and a dendritic structure, which was efficient for the esterification and transesterification rea…
Understanding factors that drive protein-protein association is of fundamental importance. We show that a single geometric parameter in crystal structures of protein-protein complexes, the angle between the electric dipole of one subunit and the partner-generated electric field at the same subunit, linearly correlates…
Three dimensional self‐consistent field theoretic simulations have been performed to determine the equilibrium morphologies formed by linear ABC triblock polymer melts confined between two parallel plates that favor the middle block. Our primary goal is to elucidate the conditions under which the perpendicular lamella…
Abstract Graphene has been well‐known for its outstanding electrochemical properties over the years owing to its zero band gap and structural advantages. Lately, Cd3As2, a three‐dimensional (3D) Dirac semi‐metal, has been fervently explored in the field of material physics due to its high electron carrier mobility and…
Identifying the contributions to thermodynamic stability of capsids is of fundamental and practical importance. Here we use simulation to assess how mutations affect the stability of lumazine synthase from the hyperthermophile Aquifex aeolicus, a T = 1 icosahedral capsid; in the simulations the icosahedral symmetry of…
Dynamic magnetic susceptibility of a laminated composite of FeSiB/Pb(ZrTi)O3/FeSiB was measured. Alternating magnetic and electric fields in the ultrasonic range were simultaneously applied to excite the first mode of the longitudinal resonant vibrations of the composite sample. Significant enhancement of the suscepti…
Structure refinement for copper indium diselenide, CuInSe 2 , based on powder diffraction data is reported. The studied sample was prepared by grinding a single crystal grown using the vertical Bridgman–Stockbarger method. The diffraction data were collected using a high‐resolution powder diffractometer. Rietveld refi…
We present a versatile approach for the synthesis of cyclic peptide amphiphiles of the hormone somatostatin (SST) with tunable lipophilic tails to program bioactive nanoarchitectures. A novel bis-alkylation reagent is synthesized that facilitates the functionalization of SST with a thiol anchor. Different hydrophobic…
Abstract Two zinc(II) compounds, namely [Zn5(AmTAZ)6(OH)2]n·2n(NO3)·6n(H2O) (1) and [Zn3(AmTAZ)2(mal)2]n (2) (HAmTAZ = 3‐amino‐1,2,4‐triazole, H2mal = malonic acid), were hydrothermally synthesized and characterized by elemental analysis, IR spectroscopy, and X‐ray diffraction.
