Provided are: an ink flow rate design which has an excellent mottle phenomenon suppression effect, a smooth writing feeling, excellent initial writing properties (not being erased at the beginning), quick-drying properties, no ink stretching during wiping due to mottle, and improved wire jumping, thereby ensuring a stable ink flow rate without relying on a tip; an oil-based ink composition for a ballpoint pen, which is capable of suppressing mottle and quick-drying properties, and which is also capable of improving print-through properties; and an oily ballpoint pen. The oil-based ink composition for ballpoint pens is characterized by containing at least a colorant, a resin component, a solvent and water, the content of the solvent and water being 40% by mass or more with respect to the total amount of the ink composition, and the content of the solvent and water being 40% by mass or more when a resin having a mass-average molecular weight of 40,000 or more is contained as the resin component. The content of the resin component is 0.5 mass% or less relative to the total amount of the ink composition, and the weight loss ratio A when the ink composition is left to stand for 2 hours in an open state at 50 DEG C and a relative humidity of 35 + / -5% RH is 25% or more. And the ratio A / B of the weight loss ratio A to the weight loss ratio B when the ink composition is left to stand for 2 hours in an open state in an environment of 50 DEG C and a relative humidity of 85 + / -5% RH is 0.8-1.2. The oil-based ballpoint pen is characterized in that the oil-based ink composition for the ballpoint pen is loaded.

The invention relates to the field of bioelectrochemistry, in particular to a composition, biological ink, a biological electrode material and application thereof. The invention provides a composition, which comprises a hydrogel and Shewanella oneidensis MR-1, and is characterized in that the hydrogel and the Shewanella oneidensis MR-1 are combined to form the composition, and the hydrogel and the Shewanella oneidensis MR-1 are combined to form the composition. The hydrogel is prepared from polyacrylamide and sodium alginate.

The invention relates to the technical field of 3D printing, and particularly provides a degradable 3D printing material as well as a preparation method and application thereof, the tensile strength of the degradable 3D printing material is 20-33 MPa, and the tensile elongation at break is 6-31%. The degradable 3D printing material has moderate semi-crystallization time, the shrinkage rate and the warping rate of a printed piece are remarkably reduced, specifically, the shrinkage rate of the printed piece is not larger than 2.5%, the warping rate of the printed piece is not larger than 2%, the printed piece does not have a wiredrawing phenomenon in the printing process, meanwhile, the degradable 3D printing material has excellent tensile strength and tensile elongation at break, and the degradable 3D printing material has good application prospects. According to the degradable 3D printing material disclosed by the invention, the degradable 3D printing material has excellent mechanical properties, is easy to degrade in the environment, and particularly can be effectively degraded in a marine environment, so that the degradable 3D printing material has relatively high environmental protection value and relatively wide application prospects.

This disclosure presents an ink for glass inkjet printing and its preparation method, comprising the following components by weight: 18-25 parts pigment; 30-40 parts glass powder frit; and 30-50 parts dispersion. The pigment is copper chromium black, and the dispersion includes a solvent, a dispersant, and additives. This ink has low viscosity and excellent flowability, allowing for smooth printing of complex patterns. It effectively suppresses diffusion, and combined with the high blackness of the copper chromium black pigment, it provides high pattern clarity.

The invention belongs to the technical field of bio-printing, and particularly discloses bio-ink of light-curable Matrigel matrigel, a preparation method and application in volume bio-printing.The bio-ink is prepared by mixing hydrogel and Matrigel matrigel and then adding a photoinitiator, controllable curing can be achieved under irradiation of a light source, and the bio-ink has the advantages that the bio-ink can be applied to volume bio-printing; the problem that in the prior art, due to the fact that Matrigel matrigel lacks photosensitive groups, photo-crosslinking reaction cannot be carried out is solved, the bio-ink is further mixed with a biological medium, the composite bio-ink is obtained and perfectly compatible with the GLVBP technology, a printed and formed structure has high precision, high cell viability and good biocompatibility, and the composite bio-ink can be used for preparing the light-sensitive matrix gel. The method has a wide application prospect in the biomedical fields of organoid culture, tissue engineering and the like.
