In this paper, we report on the synthesis of Cu nanoparticles through a single-precursor route by controlling the growth temperature. Selective adsorption of oleylamine on various crystal planes may play an important role in the growth process. The understanding of this self-assembling process will help us develop reliable and reproducible methods to synthesis other three dimensional nanostruct...

The notation and terminology used in this paper have been introduced in the following papers: [3], [6], [4], [5], [10], [11], [7], [2], [1], [9], and [8]. In this paper X, Y denote sets, G denotes a group, and n denotes a natural number. Let us consider X. Note that ∅X,∅ is onto. Let us observe that every set which is permutational is also functional. Let us consider X. The functor permutations...

Chemical grafting of 3-aminipropyl triethoxysilane to carbonized bagasse and acidification of amino groups leads us to introduce a new, efficient and green solid acid catalyst. We used the Fourier-transform infrared spectroscopy (FT-IR), X-Ray Diffraction (XRD), Thermogravimetric analysis (TGA), Field Emission Scanning Electron Microscope (FE-SEM), elemental-mapping and Energy Dispersive X-ray ...

For simplicity, we follow the rules: k, n, p, K, N are natural numbers, x, y, e1 are real numbers, s1, s2, s3 are sequences of real numbers, and s4 is a finite sequence of elements of R. Let us consider x. We introduce x is irrational as an antonym of x is rational. Let us consider x, y. We introduce x as a synonym of x. One can prove the following two propositions: (1) If p is prime, then √ p ...

The aim of this study was to determine the correlation of ultrasonographic estimates of testicular volume with true testicular volume and to compare the accuracy and precision of the three most commonly utilized formulas. A total of 15 patients underwent high-resolution ultrasonography (US) analysis for testicular volume before orchiectomy. Testicular volume was calculated using three common fo...

Implicit bias has recently gained much attention in scholarly attempts to understand and explain different forms of social injustice by identifying causally relevant mental states in individual’ minds. Here we question the explanatory power of implicit bias in a particular type of injustice, testimonial injustice, and more generally in what we call speech injustice. Testimonial injustice occurs...
