Abstract Differential scanning calorimetry was used to identify the
types of fats in spreadable food. Three types of commercial margarine and
three types of butter and a homemade product were analyzed. The presence of
vegetable oils in two of the types of butter analyzed was identified. In one
of the samples of margarine analyzed, the presence of saturated fats was
highlighted, although according to the producer, it would contain only
unsaturated vegetable fats. It has been shown that the DSC technique can be
used to identify adulteration of butter or margarine and this method has the
advantage of requiring a very small amount of samples, very good
reproducibility and a short time for analysis. Keywords: DSC, margarine,
butter, adulteration of spreadable foods.

Abstract Due to the latest studies on the potential applications of
azopolymers in the biological field as a support for cell seeding, it is
necessary to study how azo-polysiloxanic chains are reorganizing depending
on the film thickness and the type of support on which polymeric film is
deposited. In addition to the fact that there are not many articles that try
to explain the modification of azopolymers under the influence of aqueous
media, this study helps to form an overview of how the chains are
reorganized at the surface of the film and its depth, studying the variation
of water contact angle of azo-polysiloxanic samples deposited on different
supports with variable film thicknesses. Results indicate pattern behaviour
of chain arrangements function of film thickness no matter the type of
support. Keywords: contact angle, surface properties, azo-polymers,
polysiloxane, azo-derivates.

Abstract Environmental problems are more prevalent nowadays and one
of the big concerns is water contamination by highly toxic pollutants. The
employment of adsorption technologies constitutes a powerful tool for the
reduction of water pollution because of the mild conditions required by
adsorption and its good efficiency in pollutant removal processes. Defined
by a versatile micro/nanotexture layered double hydroxides (LDH) can be
fabricated to own specific nanoarchitectonics hence, they are proposed
nowadays as efficient adsorbents. This work presents MgAlLDH and the derived
calcined forms to be employed as efficient adsorbents to treat aqueous
mediums polluted with industrial dyes (e.g.: Nylosan Navy). Results reveal a
strong connection between the adsorption efficiency and the
micro/nanomorphology features of the LDH. The structure and morphology
properties of the LDHs were studied by XRD, FESEM and N2 adsorption
techniques. These findings might pave the way to establish novel solutions
to remove toxic compounds from aqueous mediums by using LDHs as efficient
environmental cleaners in water technologies. Keywords: LDH, pollutant,
nano/micromorphology, adsorption.

Abstract Modified fly ash materials are currently on an upward trend
internationally. The recovery of waste such as ash resulting in obtaining
new products has an economic advantage but also has a significant impact on
the environment because of reducing pollution due to storage. At present,
there are many methods to synthesize new materials from wastes, the best
known being fly ash. For the synthesis of novel materials, the most
well-known methods will be used. It is known that the methods are formed of
a single or two stages. The direct hydrothermal conversion of a mixture of
ash and alkaline solution (NaOH, KOH) is the first and most common approach,
however only 50% of the ash can be transformed in this instance. The second
method involves combining the ash with KOH and fusing the mixture at high
temperatures. This procedure results in a sophisticated conversion.
According to literature studies, the conversion of ash can be done by using
microwave ovens or ultrasonic baths, the conversion time in this case being
reduced to 1 - 2 hours. The direct technique was proposed to be utilized to
create novel materials by synthesis based on these processes, with numerous
applications in industries such as building and agriculture. Keywords:
fly ash, synthesis, direct hydrothermal conversion, alkaline solution,
microwave ovens, ultrasonic baths.

Abstract This paper study the rheological behavior of a cream
obtained with natural ingredients, but also one commercially available, in
which concentrated alcoholic basil extract was incorporated. The extract was
obtained by using the Soxhlet extraction method. The experimental results
showed that the creams have a time dependent pseudo plastic rheological
behavior, with pleasant appearance and fine texture and is moderately
absorbed into the skin, providing hydration, softness and flexibility, as
well as a characteristic basil smell. Keywords: rheology, cold cream,
Soxhlet alcoholic basil extract.
