Here we summarize our recent findings in the area of zeolite synthesis, focusing on pathways to control crystallization in the absence of organics, tailoring crystal habit with growth modifiers, and pioneering techniques in zeolite surface science to elucidate the mechanisms of growth.
The formation of atomically precise covalent networks directly on a surface is a promising approach to produce single layers of two-dimensional organic materials (2D polymers). In the emerging field of on-surface synthesis, there is an urgent need for finding a rationale to new reaction pathways taking place directly…
This paper reports the effect of temperature on the properties of TiO_2 nanomaterials, synthesis and characterization. TiO2 powders were synthesized by sol-gel method using TiCl4 solution added in deionized water in ice bath under fume hood followed by the addition of ethanol with vigorous stirring for 30 min at room…
A multifunctional perylenediimide derivative ( DTPDI ) can be used as a recyclable specific Hg 2+ ion sensor and an efficient DNA delivery carrier.
A potentially cost-effective and scalable method to stabilize pH in microalgal batch cultures is proposed in this study. The cultures were supplied with different concentrations of CO 2 enriched gas and controlled amounts of bicarbonate were added. An empirical model correlating the equilibrium pH to bicarbonate and C…
Thermally stable poly(triphenylamine) (PTPA) synthesized by an oxidative coupling reaction is used as the functional layer in memory devices, which exhibit non-volatile bistable resistive switching behavior with a large ON/OFF ratio over 5 × 10(8), a long retention time exceeding 8 × 10(3) s and a wide working tempera…
In this work, novel upconversion lanthanide oxyfluoride (LnOF:Yb3+, Er3+, Ln = La, Y, Gd) inverse opal photonic crystals (IOPCs) were successfully fabricated by the sol–gel method combined with polymethylmethacrylate (PMMA) template technique and the modulation of the photonic stop band (PSB) on the green emissions 2H…
The effect of Mg and Ca treatment on the behavior and the particle size of inclusions in bearing steels were studied by industrial experiments and thermodynamic calculations. The results showed that the excess addition of Mg wires is not conducive to control the total oxygen content in bearing steel because of the sec…
The gate-bias stress stability of p-type tin monoxide (SnO) thin-film transistors (TFTs) is investigated. The SnO TFT exhibits a threshold voltage of 2.5 V, a field-effect hole mobility of 0.24 cm2V-1s-1, a sub-threshold swing of 2 V/decade, and an ON/OFF current ratio of 103. Under gate-bias stress, the transfer char…
Understanding the interfacial properties of soft poly(N-isopropylacrylamide) (PNIPAM) microgels covering an oil-water interface is essential for engineering stimuli-responsive emulsions stabilized by soft microgel particles. This study presents a systematic study on the interfacial properties of the PNIPAM-microgel-la…
A carbon nitride array (CNA) material has been constructed using a sacrificial diatom template. A regular carbon nitride nanorod array could be replicated from the periodic and regular nanochannel array of the template. The directional charge transport properties and high light harvesting capability of the CNA gives m…
A dinuclear Co III complex oxidizes 3,5-di- tert -butylcatechol by binding to two molecules of the substrate simultaneously during oxidation along with the formation of H 2 O 2 .
Yolk–shell structured pH-responsive Fe 3 O 4 @PMAA microspheres have been prepared for adsorption of metal ions and drug delivery by combined sol–gel reaction, emulsion polymerization and selective etching methods accompanying hydrolysis of PMMA shells of core–shell–shell Fe 3 O 4 @SiO 2 @PMMA composite microspheres.
Research on microbially induced calcite precipitation (MICP) is reported. MICP may serve to reduce near-wellbore permeability, reduce CO 2 – related corrosion, and lower the risk of unwanted migration of CO 2 or other fluids. MICP research on the lab scale has demonstrated the ability to seal sandstone cores using inj…
Coacervation is a phenomenon in which a colloidal dispersion separates into two immiscible liquid phases: a liquid rich in colloidal phase in equilibrium with another diluted liquid phase. Surfactant coacervation here refers to coacervation whose main components are surfactants with low molecular weights. Over the pas…
Compact and specularly reflective tin(II)selenide (SnSe) thin films 100–310 nm in thickness are deposited on Na 2 S-treated glass substrates from a chemical bath containing tin(II)chloride, triethanolamine, sodium hydroxide, and sodium selenosulfate. These thin films are of orthorhombic crystalline structure, which re…
We present here a review of the mechanistic studies of the Wacker process stressing the long controversy about the key reaction steps. We give an overview of the previous experimental and theoretical studies on the topic. Then we describe the importance of the most recent Ab Initio Molecular Dynamics (AIMD) calculatio…
Novel 3D hollow cage-like α-Fe 2 O 3 and Fe microspheres were fabricated by electrospinning followed by an annealing process for the first time.
Structural, electrical and optical properties of CuInS2 thin films of various thicknesses, grown on heated glass substrates at 100 °C by thermal evaporation method were studied. These films were annealed in air atmosphere at temperature of 200 °C. The thickness of the CIS films was varied from 436 to 80 nm. It was fou…
Extensive efforts have been devoted to improve the anode performance of a microbial fuel cell (MFC) by using modified carbon-based anode materials, but most of them did not recognize that the power performance measured by the commonly-used varying circuit resistance (VCR) or linear sweep voltammetry (LSV) method was o…
