A resin composition contains a base resin containing a photopolymerizable compound and a photopolymerization initiator, and surface-modified silica particles, wherein the surface-modified silica particles have, as a silicone structural unit, a T unit in which three oxygen atoms are bonded to a silicon atom, and the proportion of a T1 unit contained in the T unit is 29 mol % or less.

Provided herein are mycelium materials and methods for production thereof. In some embodiments, a mycelium material includes: a cultivated mycelium material including one or more masses of branching hyphae, wherein the one or more masses of branching hyphae may be disrupted or pressed and/or a bonding agent may be combined with the cultivated mycelium material. Methods of producing a mycelium material are also provided.

An anti-biofouling shape-memory composite aerogel includes a unidirectional chitosan aerogel channel, a plant polyphenol coating, and a polyphenol/iron ion chelate. The plant polyphenol coating is evenly distributed on an inner wall of the unidirectional chitosan aerogel channel, and the polyphenol/iron ion chelate is located at a top end of the unidirectional chitosan aerogel channel. The anti-biofouling chitosan-based composite aerogel has an evaporation rate of 1.96 kg.Math.m.sup.2.Math.h.sup.1 at an illumination intensity of 1 kW/m.sup.2. The composite aerogel has shape-memory properties, and can quickly restore its original shape in water after extrusion, thereby accelerating the diffusion of substances to complete the modification of inner channels. In this way, desirable anti-biofouling ability is achieved, and excellent structural stability as well as continuous and efficient photothermal water evaporation are guaranteed in a complex water environment.

A closure for a product-retaining container is constructed for being inserted and securely retained in a portal-forming neck of said container. The closure comprises: a plastic material comprising at least one thermoplastic polymer; a plurality of particles comprising cork; and at least one processing aid. Optionally, one or more additives and/or blowing agents may be included. A method for manufacturing a closure comprises intimately combining multiple components, heating the resulting composition to form a melt, forming a closure precursor from the melt, and optionally cutting and/or finishing the closure precursor to form the closure.
