According to the cell phone frame provided in the embodiment of the present invention, the first side surface of the first plate is roughened to form striations, which increases the area of the first plate and the second plate subjected to rolling, so that a composite plate produced by combining the first plate and the second plate has a higher bonding strength, thereby ensuring that the cell phone frame is firmer.

A liquid optically clear adhesive (LOCA) for bonding optical substrates includes siloxane and epoxy-containing oligomers, a UV-activated photo-acid generator, a cross-linker additive, a solvent; and a reactive plasticizer, such as an additive of Structure 1. In one example, the additive of Structure 1 constitutes about 1-7% of a total mass of the LOCA excluding the solvent. R.sub.1, R.sub.2, and R.sub.3 of Structure 1 include methoxide, ethoxide, propoxide, or a combination thereof. R.sub.4 of Structure 1 includes an alkyl chain that is linear or branched and includes 2-8 carbons. The LOCA material is characterized by a refractive index equal to or greater than about 1.6 at 450 nm and an optical absorption below about 0.1% per micrometer of a thickness of the LOCA material.

A textile and a method of making the same comprising a microplastic collection layer, a microplastic capture layer, and a water resistant protection layer. The microplastic collection outer layer includes a plurality of openings therein for collecting microplastics from a body of water. The microplastic attraction and capture middle layer attracts and captures the microplastics collected by the microplastic collection outer layer. The water resistant protection layer protects a wearer's skin against the microplastics captured by the microplastic attraction and capture middle layer.

A machine for making insulation may include two or more rotatory members configured to pull a precut insulation product at a first rate, wherein the precut insulation product comprises a first paper layer, a second paper layer, and a continuous paper core sheet, a first restraint and a second restraint spaced apart a predetermined distance to create a first space therebetween, and two or more second rotary members configured to feed a continuous paper sheet at a second rate into the first space such that the continuous paper sheet forms a plurality of flexible loops defining a plurality of air channels that extend in a direction that is substantially perpendicular with a machine direction. The first rate may be slower than the second rate.

The presently disclosed subject matter generally relates to recyclable insulation material for shipping containers, groceries bags, etc., machines for making the recyclable insulation material, and methods for the making the recyclable insulation material. In one aspect, an insulation product may include a first layer and a first continuous paper sheet formed into a first plurality of flexible loops disposed on and attached to the first layer and defining a first plurality of air channels that extend in a direction that is substantially perpendicular with a machine direction of the insulation product. A take up factor of the first continuous paper sheet to the first layer may be greater than 1:1.

A core structure (300) for a composite panel for an aircraft, for example a door fairing for a landing gear bay, including a sandwich structure in which core cells (301) are sandwiched between first and second body sides (skins 303, 305). The core cells are square or rectangular in shape and each have a void formed by cell walls (307). The first and second body sides and the cell walls include laminated composite material of multiple layers. Drainage holes (320) in the cell walls form one or more direct drainage paths (P2, P3) for the flow of fluid from the core structure. The core cells include first and second sheets of cells reversibly mounted to each other, such that the void of each cell is formed in part by the first sheet and in part by the second sheet.
