Enabling Higher Photoelectrochemical Efficiency of TiO2 via Controlled Formation of Disordered Shell: Alternative to Hydrogenation Process

04.05.2016 | Vitaly Gurylev; Mrinalini mishra; Chung-Yi Su; Tsong-Pyng Perng, Chemical Communication, 2016

A simple one-step and low-temperature process was developed to form an amorphous overlayer on the crystalline TiO2 film by atomic layer deposition. This composite structure is beneficial for improved photoelectrochemical efficiency since the as-deposited amorphous layer showed unique properties ...

One-step growth of lanthanoid metal-organic framework (MOF) films under solvothermal conditions for temperature sensing

04.05.2016 | Xue Liu; Wen Tian Fu; Elisabeth Bouwman, Chemical Communication, 2016

A one-step direct solvothermal synthesis of an Ln metal-organic framework (MOF) film is reported. The LnHL (Ln=Tb and Gd) films that were deposited on a Gd2O3 subtrate are continuous and smooth. The Gd0.9Tb0.1HL film can be used as a ratiometric thermometer, showing good linear behaviour in the ...

Fractional Electron Number, Temperature, and Perturbations in Chemical Reactions

04.05.2016 | Ramon Alain Miranda-Quintana; Paul Ayers, Physical Chemistry Chemical Physics, 2016

We provide a perspective on the role of non-integer electron number in the density functional theory approach to chemical reactivity (conceptual DFT), emphasizing that it is important to not only treat reagents as open systems, but also as non-isolated systems, in contact with their surroundings. ...

Mild synthesis of {001} facets predominated Bi2O2CO3 clusters with outstanding simulated sunlight photocatalytic activities

04.05.2016 | Li-Min Yang; Guoying Zhang; Hai-Rong Wang; Xue Bai; Xing-Qi Shen; Jing-Wang Liu; Dongzhao Gao, CrystEngComm, 2016

Bi2O2CO3 clusters built up of ultrathin nanosheets with predominated {001} facets were facilely synthesized via a template-free hydrothermal strategy at a mild temperature of 60 °C. The Na2CO3 dosage and reaction temperature are confirmed to be key parameters to obtain the hydrolysis product of ...

Dominant Factors Limiting Optical Gain in Layered Two-Dimensional Halide Perovskites Thin Films

04.05.2016 | Wee Kiang Chong; Krishnamurthy Thirumal; David Giovanni; Teck Wee Goh; Xuefeng Liu; Nripan Mathews; Subodh Gautam Mh ..., Physical Chemistry Chemical Physics, 2016

Semiconductors are the ubiquitous gain media for coherent light sources. Solution-processed three-dimensional (3D) halide perovskites (e.g., CH3NH3PbI3) with their outstanding room temperature optical gain properties is the latest member of this family. Their two-dimensional (2D) layered ...

Illuminating microemulsions: ionic liquid–CdS quantum dots hybrid materials as potential white light harvesting systems

04.05.2016 | Krishnaiah Damarla; Pankaj Bharmoria; K. Srinivasa Rao; Praveen Singh Gehlot; Arvind Kumar, Chemical Communication, 2016

Microemulsions (MEs) comprising of 2-hydroxyethylammonium formate, (HO-EAF), isooctane and dioctylsulfosuccinate proliniumisopropylester ([ProC3]AOT) have been constructed and used to prepare and stabilize CdS Quantum Dots (QDs) at room temperature. Such hybrid materials exhibited tunable light ...

On the urea’s ability to stabilize the globule state of poly(N-isopropylacrylamide)

04.05.2016 | Andrea Pica; Giuseppe Graziano, Physical Chemistry Chemical Physics, 2016

Experimental measurements have shown that urea decreases the temperature of the coil-to-globule collapse transition of poly(N-isopropylacrylamide), whereas tetramethylurea increases the collapse temperature [J.Am.Chem.Soc., 2009, 131, 9304]. These data indicate that urea is a stabilizing agent of ...
