In the field of biotechnology, nanoparticles are one of the fastest developing areas of research. While chemical synthesis of nanoparticles is the standard, biological synthesis offers a safer and more environmentally friendly alternative. This experiment analyzed the inhibition of microbial growth when the microbes w…
Given the concern for diminishing fossil fuel supplies and the environmental consequences of fossil fuels, it is vital to seek out alternative energy resources. Our laboratory seeks to study the use of the algal species, Chlorella Protothecoides, in biofuel production by identifying the genes that control lipid produc…
The article considers the process of elastic-plastic transition in welded samples from low-carbon steel. Two methods of manual arc welding with a consumable electrode are used: traditional fixed arc and pulse welding with controlled heat input. It is shown that both methods are identical with respect to the obtained s…

Ảnh hưởng của các thông số công nghệ như nhiệt độ và thời gian phát triển tinh thể, tỉ lệ Cu:In trong các tiền chất lên tính chất…
Abstract We report an organic single crystal growth technique, which uses a nonvolatile liquid thin film as a crystal growth field and supplies fine droplets containing solute from the surface of the liquid thin film uniformly and continuously by electrospray deposition. Here, we investigated the relationships between…

This CRADA was a collaborative agreement between the above parties to develop a more efficient ultraviolet (UV) oxidation process than the existing commercial processes. The proposed new process would be capable of completely mineralizing the organic constiruents in aqueous mixedwastes (wastes that contain both radioa…
Coconut fiber is a very common residue in Brazil and already finds uses in different areas. This work evaluated the efficiency of this residue in the thermal insulation for later use in panels of low cost. The green fiber coconut residue was used in the production of samples for thermal and chemical analysis. By using…
Phloridzin, a natural hydoxychalcone constituent obtained from fruit trees is an antidiabetic and antineoplastic agent. Phloridzin was first isolated, for clinical pharmaceutical usage from the pear tree bark of Pyrus communis in 1838 as the first sodium-glucose linked transport 2 (SGLT2) inhibitor. Additionally, phlo…
Abstract Copper is a material used in a wide range of applications. The combination of electrical conductivity and mechanical strength is a feature which is especially important when it comes to conductive and contact materials. This combination of properties in low-alloy copper-based alloys can be achieved when the m…
Polymeric and oligomeric À-conjugated systems have garnered significant interest due to their distinctive electronic properties. These have unique moieties of a silsesquioxane nature. These can be used to produce an electric charge through external stimuli by utilizing donor-acceptor hybrid nanostructures. Significant…
We show, through experiments and simulations, that geometrically polar granular rods, rendered active by the transduction of vertical vibration, undergo a collective trapping phase transition in the presence of a V-shaped obstacle when the opening angle drops below a threshold value $\theta_c$. We propose a theoretica…
Los dendrímeros han generado un enorme interés debido a su particular estructura ramificada y su multivalencia. La extensa investigación que se ha llevado a cabo sobre este tipo de macromoléculas ha demostrado la naturaleza multidisciplinar de las mismas, describiéndose sus aplicaciones en química, física, biología, m…
В работе приведены результаты исследования квантовых точек сульфида кадмия, синтезированных по золь-гель технологии в желатиновой матрице. Образцы были получены в ходе синтеза с разным содержанием исходных реагентов, концентрация которых изменялась от 2·10-4 до 1.0 ат. % относительно воды, содержащейся в реакторе. Кри…
Màng polylactic acid (PLA) và nisin được tạo thành theo phương pháp phối trộn. Trong đó, polylactic acid và nisin đều là những sản phẩm có nguồn gốc từ vi sinh vật (từ chủng Rhizopus oryzae VLSH 01 và chủng L. lactis subsp. lactis PD15.1). Ảnh kính hiển vi điện tử quét (scanning electron microscopy – SEM) cho thấy nis…
Light emitting diodes (LEDs) are commonly used in general lighting applications due to their rapidly improving efficiency, long-life, compact, low power consumption, and high climate resistance. In this paper, the Red-Emitting Ca2Si5N8Eu2+ Phosphor was investigated like an innovative approach for improvement on the co…
The Monte Carlo Ferromagnetic Ising model was used to study the electrical properties of manganese oxides due to the charge ordering phase occurring at doping, x = 0.5. The half-doped manganites have an insulator antiferromagnetic ground state. We calculated the internal energy, specific heat, resistivity and the magn…
Ceria nanocrystals are found in commercial applications such as diesel fuel additives, catalysts for self-cleaning ovens, dental hygiene products, polishing agents for glass mirrors and ophthalmic lenses. The toxicological effects of nanoparticles on human health remain unknown, but testing revealed potential pharmaco…
We show that band topology can dramatically change the photophysics of two-dimensional semiconductors. For systems in which states near the band extrema are of multicomponent character, the spinors describing these components (pseudospins) can pick up nonzero winding numbers around the extremal k point. In these syste…
Poplar wood (Populus euramericana cv. “I-214”) was impregnated by pulse dipping at 0.7 MPa to 0.8 MPa for 30 min with a catalyst Ln∼SO42−/TiO2–SiO2, itaconic acid, and silica sol. Then, the modifier was cured within the wood micropores during in situ polymerization via kiln drying. The treated wood exhibited increased…
