Building to grow or growing to build: insights from Irish high-growth SMEs (HGSMEs)

Introduction It is recognised that, relative to the population of small- and medium-sized enterprises (SMEs), high-growth SMEs (HGSMEs) make a disproportionate contribution to economic growth. HGSMEs are frequently cited by policymakers and idealised by entrepreneurs with growth ambitions ( Volery et al., 2015 ). While extant research has identified factors that characterise HGSMEs, research has yet to provide a comprehensive explanation of the growth process. The objective of this paper is to extend this research by exploring triggers and transitions

Fabrication of Size-Tunable Silica Particles During Seed-Growth Process

The size control is one of the most important factors during seed-growth process. Although precise determination of ingredients concentrations is easily controllable during the growth process, there is still a possibility to synthesize oversized particles. Nanosized fluorescent silica particles were synthetized using Stöber process and verified using three complementary methods of particle size determination, namely Dynamic Light Scattering (DLS), Particle Tracking (PT) as well as by Transmission Electron Microscopy (TEM) and Confocal Microscopy. The final diameter was verified by DLS and estimated to 494 nm. Parameters necessary to control the size were derived.

Optimal growth processes in a non-stationary Gale economy with a multilane production turnpike

Abstract

The topic of the paper is relevant in the field of optimal growth theory and therefore might be seen as an intellectual underpinning for research and practice in the field of transition economies and sustainable long-time development as well. It refers to the papers Panek (2015a, 2018) devoted to asymptotic properties of optimal growth properties in the non-stationary Gale type economy with single and multi-lane turn-pikes in which it was assumed that changing production technology converges in time with certain limits of technology. As far as the postulate of a non-stationary economy (here: technology change) is consistent with real processes, the hypothesis of the existence of some limiting technology may raise controversies and be difficult to verify.

In the paper, referring to the above mentioned publications and Panek (2014), a Gale-type economy with changing technology, multi-lane turnpike and time-increasing production efficiency, with no assumption concerning the existence of a limit technology will be examined.

The application of magnetic self-filter to optimization of AIN film growth process during the impulse plasma deposition synthesis

Abstract

This work presents the very first results of the application of plasma magnetic filtering achieved by a coil coupled with an electrical circuit of a coaxial accelerator during the synthesis of A1N thin films by use of Impulse Plasma Deposition method (IPD). The uniqueness of this technical solution lies in the fact that the filter is not supplied, controlled and synchronized from any external device. Our solution uses the energy from the electrical circuit of plasma accelerator. The plasma state was described on the basis of OES studies. Estimation of the effects of plasma filtering on the film quality was carried out on the basis of characterization of structure morphology (SEM), phase and chemical composition (vibrational spectroscopy). Our work has shown that the use of the developed magnetic self-filter improved the structure of the AlN coatings synthesized under the condition of impulse plasma, especially by the minimization of the tendency to deposit metallic aluminum droplets and columnar growth.

Epitaxial regrowth of InP/InGaAs heterostructure on patterned, nonplanar substrates

wet-etching. Taking into account future applications and advantages of this method we decided to use it. To achieve V-shaped corrugations with 1 µm depth 3H 3 PO 4 :1HCl:1H 2 O solution was used [ 2 ]. To obtain various shapes of mesa stripes 1HBr:1HNO 3 :1H 2 O solution was applied [ 5 ]. Parameters of epitaxial growth process on a patterned substrate are usually poorly described. The typical information is that the MOVPE epitaxial processes were carried out at low pressure. The value of pressure in MOVPE reactor ranges from 2 kPa [ 6 ], through 4.7 kPa and 8 kPa

Effect of sintering parameters using the central composite design method, electronic structure and physical properties of yttria-partially stabilized ZrO2 commercial ceramics

experiments compared to the traditional trial and error method, providing the best combination of factors. The present paper has as its aim to explore the grain size, hardness and volumetric shrinkage of 3Y-PSZ ceramics by creating a statistical model using the CCD method. Moreover, we explained in details the electronic structure by X-ray diffraction (XRD), Rietveld refinement, clusters modeling and electron density map of 3Y-PSZ ceramics. Field emission scanning electron microscopy (FESEM) was employed to verify the sintering and growth process of 3Y-PSZ ceramics

The Influence Of Zinc On Seed Germination And Growth In The First Ontogenetic Stages In The Species Cucumis Melo L.

Abstract

The paper presents the results of a study regarding the influence of treatment with zinc in different concentrations (50 mg∕l, 100 mg∕l, 200 mg ∕l, 300mg/l, 400 mg ∕l, 500 mg/l, 600 mg ∕l) on seed germination and growth in early ontogenetic stages of Cucumis melo L. We analyzed the following indicators: the percentage of germinated seeds; the length of root, the length of the hypocotyl and the length of the seedling; the number of the laterale roots; the tolerance index and the seedling vigor index. The results underline the specific variations of analysed indicators, depending on the concentrations used for the treatments of seeds. The concentrations used for treatment do not influence negatively the seed germination, but affected the seedling growth (especially the root elongation), the formation and growth process of lateral roots and the seedling vigour index. The delay effect of growth process is very pronounced in the case of high concentration.

Synthesis and formation process of zirconium dioxide nanorods

Abstract

Crystalline zirconium dioxide nanorods have been prepared by a simple hydrothermal process using zirconium hydroxide as the zirconium raw material. Zirconium dioxide nanorods are composed of monoclinic zirconium dioxide phase, which has been confirmed by the X-ray diffraction analysis. Electron microscopy observations show that the zirconium dioxide nanorods have a single crystal structure, with the rod diameter of less than 100 nm and length of 1–2 μm. Hydrothermal temperature and reaction time play essential roles in the formation and growth of the zirconium dioxide nanorods. Nucleation and crystal growth process are proposed to explain the formation and growth of the zirconium dioxide nanorods.
