Importance of well-dispersed copper species and well-developed ceria–zirconia surface during catalytic carbon dioxide hydrogenation to methanol.

Skillful proposal writing is an art of persuasive communication that can be an asset for therapists who must cope with recent cuts in government and private support. This article provides an overview of funding agencies, the basic principles of proposal writing, and the components of a proposal. Even rejection of a proposal can be educational and can contribute to eventual mastery.

The knowledge of Cr2O3 activity in slag is necessary to decarburize chromium-containing special steel while minimizing the oxidation loss chromium. In present study, firstly, phase relationship CaO–SiO2–Cr2O3 system was determined at 1573 K. Subsequently, activities two- and three-phase coexisting slags K were measured by equilibrating molten copper with oxide phases under a stream Ar + H2 CO2 ...

Focused ion beam milling is a processing technology which allows flexible direct writing of nanometer scale features efficiently substituting electron beam lithography. No mask need results in ability for patterns writing even on fragile micromechanical devices. In this work we studied the abilities of the tool for fabrication of diffraction grating couplers in silicon nitride waveguides. The g...

We present an approach to fabricate tall high aspect ratio Au microstructures by means of proton beam direct writing. Combining proton beam direct writing and electroplating, we successfully produced gold structures with sub-micrometer lateral dimensions, structure heights in excess of 11 lm, and aspect ratios over 28. Sidewall quality of the Au structures was improved by lowering the process t...

In this letter, we present the first demonstration of 2 8 power splitters made in silica-on-silicon by direct ultraviolet (UV) writing. The fabricated components are compact and exhibit good performance in terms of loss, uniformity, and bandwidth, showing that direct UV writing can become a competitive technology for fabrication of low-cost integrated optical devices.

The current study sought to explore the impact of SFL-oriented register instruction on Iranian EFL learner’ writing performance with a central focus on their English proficiency level. As its secondary aim, the study delved deeply into the learners’ perception of the register-based instruction. To these ends, 50 intermediate and 50 advanced Iranian EFL learners were selected randomly and assign...

We tested the hypothesis that engagement in a few, brief writing assignments in a nonmajors science course can improve student ability to convey critical thought about science. A sample of three papers written by students (n = 30) was coded for presence and accuracy of elements related to scientific writing. Scores for different aspects of scientific writing were significantly correlated, sugge...

This corpus-based study compares the use of the alternating ditransitive verb TELL by native speakers and Chinese learners of English. The corpora used are the written sub-corpus of ICE-GB (the British component of International Corpus of English) and CLEC (the Chinese Learner English Corpus). CLEC consists of both lowand high-proficiency L2 learners’ writing. By incorporating corpus contrastiv...

The present study explored the intensity level of authorial voice in relation to the quality of argumentative writing. 42 undergraduate learners of English as a foreign language (36 girls and 6 boys) spent 45 minutes to individually complete in-class position-taking writing tasks for three weeks. Their overall academic writing quality scores assigned based on portfolio assessment were studied i...
