I progressi raggiunti nella conoscenza delle caratteristiche biologiche delle cellule staminali e la dimostrazione della presenza di cellule progenitrici nel tessuto cardiaco adulto hanno posto le basi per lo sviluppo di nuove strategie terapeutiche che mirano alla rigenerazione del miocardio. In vivo, le cellule stam…
The development of efficient artificial leaves relies on the subtle combination of the electronic structure of molecular assemblies able to absorbing sunlight, converting light energy into electrochemical potential energy and finally transducing it into chemical accessible energy. The electronical design of these char…
The skin functions as a protective physical barrier against the outside and has a primary role to protect body from external influences such as pathogenic microorganisms and mechanical injuries. Moreover in the skin, the interaction of keratinocytes, fibroblasts and melanocytes is tightly controlled by various factors…
In the last decades, nanomedicine – the application of nanotechnology to medicine – has opened up an entirely new horizon of possibilities and applications, in particular for drug delivery and diagnostic. Indeed, a wide range of nanocarrier have been designed and realized. However, more recently researcher focused on…
In the last few years, great interest in the pharmaceutical nanotechnology field has been devoted to the development of multifunctional nanoparticles for cancer therapy, in order to improve drug efficacy and selectivity as well as to revert multidrug resistance. In this context, the general aim of this thesis was to c…
Polycaprolactone-water mixtures represent one of the most important polymer solutions with specific interactions in polymer science. Polycaprolactone (PCL) is an aliphatic polyester composed of hexanoate repeat units. It is a semicrystalline polymer with a degree of crystallinity which can reach 69%. PCL biodegrades w…
Le diatomee sono organismi unicellulari fotoautotrofi eucarioti caratterizzati da un particolare scheletro siliceo. Costituiscono il piu grande gruppo del fitoplancton marino e svolgono un ruolo ecologico essenziale costituendo la base della catena trofica marina e contribuendo al mantenimento dei cicli geochimici oce…
In questo lavoro di tesi si e utilizzato il concetto di miscela polimerica per controllare la nucleazione e la crescita delle bolle all’interno di strutture cellulari e per studiare in che modo la gestione della morfologia della miscela espansa possa essere coniugata con le proprieta chimico-fisiche dei materiali cost…
The test results for Salt Spray Resistance, Static Heat and Humidity and Marine Environment can be found in Sections 3.1.3.3, 3.1.4.3 and 3.1.5.3 respectively. In summary, both the Metalast TCP and SurTec 650 Type 2 conversion coatings perform very similar to the incumbent Type 1 conversion coating against both 6061 a…
Semiconductor-superconductor hybrid devices have been investigated for many years. In these devices the macroscopic quantum correlations typical of superconductors can be induced via proximity effect in a wide class of low-dimensional materials such as, topological insulator , ferromagnetic barriers ], graphene and in…
Les energies renouvelables sont une bonne solution a la recherche de nouvelles sources d’energie. Neanmoins celles-ci sont le plus souvent intermittentes. Les systemes de stockage d‘energie peuvent permettre de rendre compatible l’offre et la demande en energie a la fois spatialement et temporellement, et ainsi valori…
Applications of electrolytic ion water generated by the oxidation-reduction have gradually been expanded due to their strong sterilizing power and a surface active force. We demonstrate the effect of the multi-layer type electrode for effective ion water generation. The multi-layer type electrode has ability to genera…
In this research, a 6W white LED package with a Glass Remote Phosphor was developed to improve the life of an LED package. The Glass Remote Phosphor was fabricated by the Phosphor in Glass (PiG) method, wherein phosphor YAG:Ce was mixed with glass frit and then heat treated. A paste with 75wt.% of a phosphor substance…
The paper presents comparison of spectral characteristics of PMMA samples doped with new photoluminescence monomer dimethacrylate derivative of naphthalene-2,7-diol (2,7-NAF.DM). After excitation by UV radiation monomer emits yellow-green light. One PMMA sample was doped in bulk thermal polymerization process. The sec…
Experts rank climate change and energy shortage as the most important issues that we confront over the next 50 years. These problems are connected, since non-regenerative fossil fuels are responsible for greenhouse gas emission thanks to the CO2 they produce during combustion. From all the observations, it is evident…
This study aimed to obtain a better understanding on the mechanisms and controls of mineral–organic matter (OM) interactions across a range of soil types and land uses. Batch adsorption experiments were conducted to evaluate sorption capacity of different organic carbon (OC) compounds on pure minerals and their intera…
This study aims to (1) the effect of the concentration of starch and ratio mixture of plasticizer to the physical and mechanical characteristics of bioplastics (2) determine the concentration of starch and plasticizer RATIO mixture that results in physical and mechanical characteristics of bio plastics best. The exper…
以纳米蒙脱土（MMT）为原料,Zr（SO4）2 为改性剂,采用浸渍法制备Zr-MMT 用于处理低浓度含Cr（Ⅲ）废水,并研究了Zr-MMT 纳米材料的吸附机理.采用X 射线衍射（XRD）和扫描电子显微镜（SEM）对Zr-MMT纳米材料进行表征.结果表明,吸附后的Zr-MMT 表面有Cr（Ⅲ）存在;Zr-MMT 对Cr（Ⅲ）的吸附方式主要有离子交换、静电吸附和表面吸附,并且该吸附过程可以用二级动力学方程和Langmuir方程进行很好的拟合.解决了鞣制废物资源化利用中Zr（OH）4 和ZrO2 在强酸强碱性条件下不稳定的问题,制得了一种稳定性好的纳米吸附材料.

The National Institute of Standards and Technology operates a 20 MW research reactor for neutron-based research. The heavy-water moderated and cooled reactor is fueled with high-enriched uranium (HEU) but a program to convert the reactor to low-enriched uranium (LEU) fuel is underway. Among other requirements, a reloa…
