The research presented in the paper is based on the idea of optimizing the processing and use of cosmetotextiles. The production of these materials involved: Use of a textile knitted support with 3D surface geometry (in order to create a massaging effect) made of bamboo yarns (for improved comfort characteristics). Functionalization of the textile support with air plasma treatment improving the hydrophilic characteristics and increasing the surface energy available, facilitating the bonding of microcapsules.The paper highlights the improvement of microcapsules embedding by the functionalization of a textile knitted support with 3D surface geometry, made of bamboo yarns. The surface of the bamboo knitted fabric was pre-functionalized by an air atmospheric plasma treatment irradiation before applying microcapsules; the characterization and quantification of the amount of microcapsules bonded to the fibers were being carried out using a co-assisted technique: gas chromatography associated with mass spectrometry, scanning electron microscopy, electric parameters analysis (zeta potential ξ), and determination of air permeability. © 2014, The Textile Institute.

In the last years metal/clays, aluminosilicates with properties and characteristics of microporous materials, have received more attention, due to the possibility of their use as matrix for nanoparticles encapsulation and stabilization processes. Some types of clays were comparatively evaluated for treating the simulated radioactive wastewater. The raw clay from Valea Chioarului Romania and its pillared forms with Al, Fe, pillars for decontamination of waste-waters with medium and low radioactivity were used. Characterization of the obtained materials was carried out using techniques such as X-ray diffraction, Fourier transform infrared spectroscopy, BET analyses and thermogravimetric analysis (DTG-TG), respectively. Also, the thermal stability of nanocomposites was highly superior to native clay due to the presence of the well-dispersed clay nanolayer, which has a barrier property in a composite system. Clay nanocomposite sample materials were obtained with good thermal stability after calcination. Clay nanocomposites samples were evaluated for remediation of radioactive effluents by treating the radioactive wastes streams. The ion-exchange characteristics and the abilities to uptake radioisotopes of indigene clay from Valea Chioarului area-Romania were examined. The results showed that the precursor used in sample preparation influenced the structural and textural properties of nanocomposites and also capability of prepared modified clay samples by pillaring to be potential candidates for use in connection with environmental protection, remediation of radioactive effluents, respectively. © 2012 Akadémiai Kiadó, Budapest, Hungary.

In this paper, we present a portable equipment for bio-chemical measurement, designed for monitoring the functional parameters of the persons undergoing cardiological and/or effort tests. This equipment is based on a digital signal processing microcontroller, and has more functions: the acquisition of ECG signals, mainly from the participant running in the effort tests for the anaerobic threshold; the acquisition of breathing parameters; the acquisition of blood pressure signal in a non-invasive way; the acquisition of other specific parameters; the processing of the acquired data in real time for various alarms; displaying data on the PDA screen; the wireless transmission of the acquired signals in real time or of the stored ones for further analysis. These are provided by the equipment used for monitoring functional parameters from patients with coronary disease, to ordinary people. Furthermore, the equipment thus can become an essential tool for the training equipment of the athletes.
