Abstract: Multiresistant bacterial strains are a very serious clinical problem in a hospital environment. Solving these types of nosocomial infections requires new and unique approaches. [..] Read more

Abstract: Due to their specific properties, nanofibrous materials are increasingly used in regenerative medicine and tissue engineering. Nanofibrous materials can be used as tissue scaffolds for injured (damaged) tissue. [..] Read more

Abstract: The aim of this work is to study the changes in the properties of Polylactic acid (PLA) fabrics after plasma treatment at atmospheric pressure. Volume dielectric barrier discharge (VDBD) and diffuse coplanar surface barrier discharge (DCSBD) were applied to modify the PLA surface in ambient air using exposure times 1 -10s. [..] Read more

Abstract: Malic acid is one of the most important acids in the food industry and in fermentation processes. Especially in the wine fermentation process, its decreasing concentration plays a significant role. [..] Read more

Abstract: In this study, we introduce a method for modifying poly(lactic acid) (PLA) filament, which is adjustable to enhance the rheological properties and biocompatibility of printed products or impart specific characteristics by bonding nanoparticles onto the surface of graphene oxide. What distinguishes our method is the post-production modification of PLA filament before the printing process. [..] Read more

Abstract: Polyvinylidenefluoride (PVDF) is a biocompatible, nondegradable material commonly used in medicine as a surgical suture. However, the use of PVDF in the field of tissue engineering has more significant potential. [..] Read more

Abstract: Nano-sized exosomes are essential for intercellular communication, especially in cancer biology. Human produces exosomes that may modulate the tumor microenvironment and cellular behaviour. [..] Read more

Abstract: Photodynamic therapy (PDT), a clinically approved cancer treatment strategy, has the potential to cure pancreatic cancer with minimal side effects. PDT primarily uses visible wavelengths to directly activate hydrophobic photosensitizers, which may be insufficient for deep-seated cancer cells in clinical practice due to poor penetration.

Abstract: The notion of theragnostic brings together such terms as telemedicine, bionanosensors, and personalized medicine. Synergy in the mainstream areas can bring new approaches and provide a fresh perspective on long-established areas. [..] Read more

Abstract: In the search for a suitable and biocompatible material with high photothermal efficacy for hyperthermic application in nanomedicine, gold (Au) nanocolloid solutions with a surface plasmon resonance located in the near-infrared spectral region were prepared using a one-step environmentally friendly phytosynthetic process. The room-temperature process involves a liquid extract of Mentha × piperita leaves and Au(III) aqueous solutions, and no additional reagents or surfactants are required. [..] Read more

Abstract: 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride (EDC) is the most used carbodiimide for conjugating biological substances containing carboxyls and amines. The use of EDC for conjugating a protein containing amines to a particle with a carboxyl group is often utilized for the preparation of modified nanoparticles, which are used for example in electrochemical immunosensing[1].

Abstract: In this work the P(VDF-co-HFP) was chosen as a matrix due to the better mechanical properties compared to neat PVDF. Strontium titanate (SrTiO3) was chosen as one of the lead-free ceramics and to observe its impact of modification on nanocomposite properties. [..] Read more

Abstract: Textile yarn is a group of twisted fibers with diameters of a few micrometers, requiring a nano-resolution scanner to capture precise details of the single fibers perfectly to make a digital twine of the scanned yarn. Computed tomography (CT) technology can 3D digitally scan the sample and achieve a digital twin. [..] Read more

Abstract: Correlative microscopy methods have become significant due to the possibility of examining several material properties during one measurement. Atomic Force Microscopy in Scanning Electron Microscopy (AFM-in-SEM) is a correlative method that allows the simultaneous detection and acquisition of signals from both methods. [..] Read more

Abstract: The paper focuses on preparing beta-titanium alloy Ti39Nb for nitrogen ion implantation, a process in which the surface is bombarded with nitrogen ions. To successfully introduce ions into the titanium surface, it is crucial to have a high-quality surface preparation. [..] Read more

Abstract: The increasing environmental awareness, depletion of non-renewable petroleum resource and growing demand on sustainable product development, plant fibres are actually assigned to more technical applications through the development of polymer/ natural fibre composites. Indeed, owing to their important advantages, such as low density, renewability and biodegradability, plant organic fibres represent a viable alternative to inorganic fillers or synthetic fibres in composite materials. [..] Read more

Abstract: Photoactive nanoparticles have recently gained a lot of attention as alternative antimicrobial agents since their antimicrobial properties can be enhanced by illumination. The stable and reproducible application of these conditions is crucial in order to assess the antimicrobial effect of nanoparticles, illumination and the combination of these conditions on cells. [..] Read more

Abstract: The subject of consideration in the paper are negotiations conducted within the supply chain, between its main participants, including parties cooperating in preparation of offer for final customers, parties supporting chain in logistics, as well as other external stakeholders. The objective of the paper is to distinguish and describe strategies of such negotiations, based on the authors' original concept. [..] Read more

Abstract: The purpose of this paper was to emphasize the importance of data accuracy within internal logistics systems and their extended influence on supply chains in automotive industry through a 6 month case study conducted on 3 first tier original equipment manufacturers (OEM) based in Western Romania.Data collection and analysis revealed that main issues arise due to ordering quantities mismatching actual customer demand, a wide range of order lot sizes, lead times and delivery reliability concerns and the reluctance to shift away from mainstream cost-effectiveness and towards strategic added value thinking. These issues sourced significant other related operational challenges such as excessive inventory, short-term stockouts and subsequent express shipping services or product-related inconveniences (quality and capacity levels, contracted volumes and dedicated lines).The paper sources different logistics and supply chain approaches used by the 3 OEMs, their features and operational performance, as well as their overall effectiveness which can be applied by other automotive industry suppliers to improve own results.
