An example of an inkjet ink for textile printing includes a polycarbodiimide, a pigment, a sulfonated polyester-polyurethane binder, and a liquid vehicle. Examples of the inkjet ink may be used in textile printing kits and printing methods with a textile fabric. Examples of the textile fabric may be selected from the group consisting of cotton, polyester, nylon, and silk.

A microfluidic valve may include a firing chamber having an orifice, a first portion of a liquid conduit connected to the firing chamber at a first port, a second portion of the liquid conduit connected to the firing chamber at a second port and a thermal resistor. The thermal resistor is to form a bubble within the firing chamber to expel liquid from the firing chamber through the orifice such that a first meniscus forms across the first port and a second meniscus forms across the second port to interrupt liquid flow between the first portion and the second portion of the liquid conduit.

An element substrate is provided with a fuse memory configured to store information in response to having a voltage applied thereto, a first switch configured to switch whether or not to energize the fuse memory, a resistance element, a second switch configured to switch whether or not to energize the resistance element, a first node connected to the fuse memory and the resistance element, and a second node configured to supply power to the first node from outside. Regarding the element substrate, electric charge that remains at the first node is discharged by allowing, before allowing the first switch to energize the fuse memory, the second switch to energize the resistance element from the first node.

Provided herein are systems and methods for storing digital information by assembling an identifier nucleic acid molecule from at least a first component nucleic acid molecule and a second component nucleic acid molecule. The system may include a first printhead configured to dispense a first droplet of a first solution comprising the first component nucleic acid molecule onto a coordinate on a substrate, and a second printhead configured to dispense a second droplet of a second solution comprising the second component nucleic acid molecule onto the coordinate on the substrate, such that the first and second component nucleic acid molecules are collocated on the substrate.

According to one embodiment, a size of an element substrate is reduced, and a printhead using the element substrate can print high-quality image. The multilayer structured element substrate comprises a plurality of print elements, and a circuit configured to input a data signal and a clock signal used for driving the plurality of print elements. And, a print element array formed by arranging the plurality of print elements in line is diagonally arranged with respect to a side constituting an outer shape of the element substrate. A print element at one end of the print element array is a dummy element not contributing to printing. The circuit is provided not only at the same position as that of the dummy element but also in a layer different from that of the dummy element.

In a liquid ejection head, a substrate is provided with a first inflow port located on an upstream side of a pressure chamber with respect to a direction of flow of liquids in a liquid flow passage and configured to allow a first liquid to flow into the liquid flow passage, a second inflow port located on the upstream side of the first inflow port and configured to allow a second liquid to flow into the liquid flow passage, and a lateral wall extending in a direction of extension of the liquid flow passage. At least part of the lateral wall is located above the first inflow port. In the pressure chamber, the first liquid flows in contact with a pressure generating element while the second liquid flows closer to the ejection port than the first liquid does.
