The present research highlights the use of thermochromic dye via two different processes applied on cotton fabrics. Two different chemical binders, silicone and acrylic resins were investigated and their influence on mechanical characteristics and colorimetric behavior was studied. Comparison of the two used chemical binders was made and varied results were obtained revealing significant differences and clear influence in dyeing performance via the evaluation of color strength and the different colorimetric coordinates after the thermochromic dye application under the same condition (dye concentration, binder rate, thermo-fixation time and temperature). In addition, the two tested binders revealed varied influences on handle, color fastness and mechanical properties of dyed fabrics. Knowing the importance of dyeing with thermochromic pigments allowing functional and smart textiles, the selection of appropriate and efficient binder could improve an effective application of these dyes in various medical, protection, and environmental fields

The current work investigated the study of the influence of the pretreatment of polyester textile material with atmospheric pressure oxygen plasma on its grafting behavior with chitosan biopolymer as direct grafting procedure without the use of crosslinking agents, which generally modifies the original surface properties of textiles. Firstly, polyester textile material was pre-activated with oxygen plasma treatment under referred conditions. Then chitosan polymer was grafted to pretreated polyester using pad-dry-cure simple method. The different grafting parameters such as time and curing temperature were studied. To evaluate the chemical grafting performance, FT-IR analysis was performed via ATR mode. Mechanical characterization was then conducted showing no degrading of the original mechanical properties of polyester material. The number of functional carboxylic groups formed at different steps of functionalization was evaluated using toluidine blue cationic dye. Finally, antibacterial effect of chitosan grafted polyester biomaterial was evaluated against gram-positive and gram-negative bacteria cultures. The promising results revealed the effectiveness of the plasma pretreatment of polyester process in the improvement of its grafting with chitosan biopolymer.

Primary Schiff Base of lanthanum (III) benzimidazole complex (2) [La(L)Cl 2 (H 2 O)] has been synthesized by condensation of the major ligand 2-(1H-benzimidazol-2-ylmethyliminomethyl) phenol (HL) (1) with lanthanum (III) chloride. The mixed ligand complexes were prepared with the reaction of salicylaldehyde or furfural aldehyde as bidentate and ammonia as a monodentate ligand with the main complex (2). The ligand, the major complex, and the mixed ligand complexes 2-5 were verified by elemental analysis, molar conductivity, spectral measurements (IR, 1 H, 13 C-NMR, UV), and thermo-gravimetric analysis. The ligand (1) behaves as a mono-negative tridentate compound. The oxygen atom of the phenolic group, the azomethine atom, and the Penta ring nitrogen atom benzimidazole was connected to lanthanum. This bonding relationship was unchanged in all of the mixed ligand lanthanum complexes.  Antimicrobial and anticancer effects were analyzed in vitro biological studies. To evaluate the in vitro antitumor activity in HEPG2 liver and HCT116 colon cancer cell lines, the effects of ligand 1 and mixed ligand complexes 2-5 were studied. Compared with ampicillin and amphotericin B, the prepared ligand and complexes showed antibacterial and antifungal activities. The ligand and complexes exerted cytotoxicity on the HCT116 cell line superior to that observed with the HEPG2 cell line.

Inertial effects arising from the electron mass are investigated. A longitudinal force is generated when a large current is passed in a wire. Because of this force, an additional magnetic field due to the electron mass is generated along the wire axis. When a huge current is applied to the wire, the wire explodes giving off its magnetic energy as heat and light. Massive electrodynamics is studied which allows the presence of magnetic charges (monopoles). The exploding force on a wire could also result from disintegrating the magnetic monopoles.

We investigate the electronic, structure and optical properties of half-Heusler compound CoCrSn using the Full-Potential Linearized Augmented Plane Wave Method (FLAPW) within generalized gradient approximation(GGA) and generalized gradient approximation including Hubbard U-parameter (GGA + U) for the exchange correlation term of the effective Hamiltonian based on the density functional theory(DFT). Structural optimizations were carried out for both compound which revealed that the ferromagnetic (FM) state was more stable than nonmagnetic (NM) state. So, in the (FM) state the equilibrium lattice parameter was 5.8540 Å for CoCrSn. The alloy was found to be nearly half metallic (HM) at equilibrium cell volume. Basic optical properties like dielectric function, reflectivity, energy loss function, absorption coefficient were hence determined for a range of photon energy up to12 eV (ultraviolet region).
