Press Release: Analyzing effects of multi-wall carbon nanotubes (MWCNT) & polyethylene glycol (PEG)

This research article by Dr. Koorosh Tookalloo et al is published in The Open Petroleum Engineering Journal , Volume 11, 2018


Nowadays, the maintenance of wellbore stability is a very important activity in the drilling industry. Wellbore stability can be improved by designing proper drilling fluid. Due to the characteristics of shale formations in relation to their ionic composition, clay content and very low Nano-Darcy permeability with very small nanometer-sized pore throats that are not effectively sealed by the solids in conventional drilling fluids, water invasion to these types of formations results in many problems. Choosing appropriate nanomaterials with suitable particle size and concentrations for plugging the nano-sized pores in the shale formations is key in preventing water flow into the shale region. Water base mud performance and rheological properties improve due to the importance and unique properties of MWCNT, such as thermal stability (at temperatures higher than 600 °C), high chemical stability, a significantly large surface area, a high aspect ratio, light weight, larger flexibility, high mechanical strength and superior electrical properties.

Recently Published Article – “Thermal Performance of Resource-Efficient Geopolymeric Mortars Containing Phase Change Materials”

Journal: The Open Construction & Building Technology Journal


Author(s): M. Kheradmand1F. Pacheco-Torgal12*M. Azenha3



Energy efficiency is not only the most cost effective way to reduce emissions but also a way to improve competitiveness and create employment. Geopolymeric mortars containing phase change materials-PCMs have a twofold positive impact concerning eco-efficiency. On one hand, the mortars are based on industrial waste contributing for resource efficiency. And on the other hand, PCM based mortars have the capacity to enhance the thermal performance of the buildings.


This paper reports experimental results on the thermal performance of geopolymeric mortars containing different percentages of phase-change materials-PCMs.


Five groups of alkali-activated based mortars with different PCM percentages were produced and placed on a panel within a small scale prototype for thermal performance testing.


The results show that the thermal conductivity of the mortars decreased with the increase in the percentage of the PCM.


Thermal performance of the PCM based mortars allowed for a stronger attenuation of the temperature amplitudes. Both for heating and cooling loads.


Recently Published Article – “Micro-RNAs -106a and -362-3p in Peripheral Blood of Inflammatory Bowel Disease Patients”

Journal: The Open Biochemistry Journal

MicroRNAs (miRNAs) can regulate various genes after binding to target mRNAs. Studies on Inflammatory Bowel Disease (IBD) in relation with miRNA are much less shown. The aim of the present study was to assess the expression patterns of microRNA 106a and microRNA 362-3p in peripheral blood samples of Inflammatory Bowel Disease (IBD) patients including Crohn’s Disease(CD) and Ulcerative Colitis (UC).


This study consisted of 32 CD, 32 UC patients and 32 controls. The expression level of the micro-RNAs -106a and -362-3p was determined using reverse transcription and real-time RT-PCR.


Our findings showed that MiR-106a and miR-362-3p are expressed at significantly higher levels in the peripheral blood from patients with CD and UC compared to controls. MiR-106a and miR-362-3p expression are also different in the peripheral blood ofpatients regarding the activity score of the disease. There were significant differences of miR362-3p in active UC relative to inactive UC.


Altogether our findings suggest that miR-106a and miR-363-3p can play an important role in the pathogenesis of IBD. The differences in expression of miR106a and miR362-3p in peripheral blood of the UC and CD patients in an active phase in comparison to inactive disease suggest that these miRNAs may be useful as potential biomarkers for diagnosis and monitoring the disease activity.

Recently Published Article – “Diversity Climate and Job Crafting: The Role of Age”

Journal: The Open Psychology Journal

 Author(s): Emanuela Ingusci*




In recent years, scientific interest in generational differences has increased. More attention has been paid to the younger (Y generation) and to older workers (baby boom generation), little attention has been given to the X generation, composed of people who are between 35 and 50 years old. This paper aimed to examine the role of age in the relationship between diversity climate and job crafting, focusing on the middle aged (X generation).

Objective and Methods:

Based on lifespan development, self-regulation and job demands-resources theory, we postulated that the association between diversity climate and job crafting weakens with age. Specifically, we hypothesized that age can moderate the positive relationship between diversity climate and job crafting. The participants were 271 employees from different Italian organizations.


The results from hierarchical regression analysis showed that the relationship between diversity climate and job crafting is stronger in middle aged workers rather than in older workers.


The findings suggest that diversity climate, in terms of organizational fairness, inclusion and personal diversity value can play a crucial role in the influence of job crafting which is, in turn, essential to improve positive organizational outcomes. Limitations and theoretical and operative implications are discussed.
