Bonding objects together

A method of bonding a first object to a second object includes the steps of: providing the first object including thermoplastic material in a solid state, providing the second object including a proximal surface, applying a mechanical pressing force and a mechanical excitation capable to liquefy the thermoplastic material until a flow portion of the thermoplastic material is flowable and penetrates into structures of the second object, and stopping the mechanical excitation and letting the thermoplastic material resolidify to yield a positive-fit connection between the first and the second object. The second object has a region of low density, wherein the protrusion penetrates the region of low density at least partly before the thermoplastic material is made flowable, and wherein the first object includes a protruding portion after the step of letting the thermoplastic material resolidify, the protruding portion at least partly penetrates the region of low density.

NANOPORE SENSING DEVICE

The invention relates to a method of forming a sensing device for supporting a plurality of nanopores upon an array of wells. The method involves providing a substrate, said substrate having a surface having an array of electrodes located thereon for connecting to or for configuring upon an electronic circuit. Separately, a well array structure is provided, which has an array of walls defining through-holes for defining wells. The substrate and well array structures are aligning said array of electrodes define, at least in part, a portion of the bases of respective wells at the bottom of the through holes. The resulting sensing device overcomes problems with known sensing devices by employing a substrate and/or well array structure, or hybrid thereof, that employs alternative materials or manufacturing processes.

LIGHT-TRANSMITTING DECORATED MOLDING ARTICLE AND METHOD OF FABRICATING THE SAME
20220371256 · 2022-11-24 · ·

A method of fabricating a decorated molding article includes forming an all-in-one coating on a substrate and performing a curing step, thereby forming a composite layer structure with a protective effect, a color effect, and a bonding effect. The composite layer structure may form a molded film with better physical properties (e.g., higher hardness, better protection effect, and the like) after the blister molding process. Therefore, the molded film of the embodiments may be applied to a laser engraving process to form a variety of light-transmitting decorated molding articles.
