Diatomaceous earth are sediments of unicellular algal skeletons with a well-defined hierarchical structure. Despite many tests conducted on systems using diatomaceous earth and epoxy resins, we can find many differences in the methods of acquisition and characteristics of the composite, which may considerably affect the results. In our study, we ha...
C-reactive protein (CRP) is a crucial biomarker of cardiovascular diseases and for its detection both optical and electrochemical techniques were applied. This study concerns the application of DNA aptamer as recognition layer for CRP detection. For that purpose aptamer immobilization method on gold surface was selected and the content of receptor...
Imaging of the surface of materials by atomic force microscopy under tapping and phase imaging mode, with use of modified probes is addressed. In this study, the circularly shaped holes located in varying distance from the probe base, were cut out by focused ion beam. Such modification was a consequence of the results of the previous experiments (p...
Cheap nano-clay (montmorillonite) was taken into consideration in this study as an additive to mineral oil to improve its lubricating properties. Mineral oils form the basis of speciality lubricants for food processing technology due to their biodegradability. In contrast to synthetic oils they are also less harmful. Literature indicates that nano-...
The feasibility of using gold electrodes modified with phosphorothioated oligonucleotides (PTOs) for determination of uranyl cation is described. PTOs are able of anchoring to gold surface via phosphorothioate linkers, present in its backbone. This approach is advantageous due to lack of the necessity of chemical activation before use and low cost....
The article deals with the pretreatment technique for preparing the surface of aluminum alloy EN AW 5754 before thermal spray. The surface after different pretreatments, including degreasing with acetone, chemical etching with acidic and alkali solutions, grit-blasting, cathodic cleaning, and some combinations of these techniques, has been studied....
The paper presents selected issues related to the possibility of the use of biofuels in transport, including aircraft. The book is focused on all who already got a basic knowledge of fuels, including biofuels. This is a kind of a report - a compendium of basic knowledge showing the reasons for the use of fuels from renewable sources. Also issues co...
The aim of this study was to analyse and to identify the phases which formed in 100CrMnSi6-4 bearing steel after the nanostructuring heat treatment. Especially designed thermal treatment parameters were applied in order to obtain a nanobainitic structure. Two different microscopic techniques were used for the precise examination of the microstructu...
This study concerns imaging of the structure of materials using AFM tapping (TM) and phase imaging (PI) mode, using probes modified with Focused Ion Beam (FIB). Three kinds of modifications were applied–thinning of the cantilever, sharpening of the tip and combination of these two modifications. Probes shaped in that way were used for AFM investiga...
The first stage of this study involved the preparation and seeding of innovative biomaterials with stem cell Scaffolds through a mixture of poly (3-hydroxybutyrate-co-3-hydroksy-valerat) (PHBV), poly (L-lactide-co-glycolide) (PLGA) and tricalcium phosphate (TCP). In the second stage, biomaterials were characterized using a X-ray computed microtomog...
The top layer of the systems covering a concrete surface is made of polyurethane. The polyurethane layer should be characterized by high tensile strength and abrasive wear resistance, because this material is used in workshops, corridors, and warehouses. Up till now the systems have been a mixture of polyurethane and different fillers. The recyclat...

Every time i working with hyaluronic acid I got some bubbles inside gel. It desn't matter in lab and do not affect on the acid. Few days ago I saw syringe (with a needle) with clear hyaluronic acid without any bubbles. Friend send me a photo of bottle with the product without bubbles too. How do they made it??? I was trying vacuum suction but did not get proper effect.
Got different information according to standard DIN 22252:2012 "Round steel link chains for use in continuous conveyors and winning equipment in mining". Is it outdated or current? I do not know if I will find few data inside, so if anyone could upload I would be grateful.
I know there are many combination of ZrCuNiAl bulk metallic glass composition, but I asking only about the temperature range.
I welding steel 316 in an argon atmosphere. The atmosphere is in a closed cycle. Filters are very often clogged. What other than hepa filters are used to purify the atmosphere from solid particles?
Picture of size below.
As far i know, for time to time, someone looking for the software to measure elements on the photo/image. Many of us using ImageJ, but writing measurement to photo needs some manipulations. I found - I hope it is freeware - IC MEASURE, download here: https://www.theimagingsource.com/support/downloads-for-windows/end-user-software/icmeasure/
If you know any similar freeware, let us know, please.
