Abstract: A container device and methods of operation and assembly of the same are provided. The container device is formed from a foldable material and includes interior locking mechanisms that prevent an inner box from being removed from an outer cover unless a user depresses a portion of the outer box to disengage an internal locking mechanism. A secondary locking mechanism prevents the inner box from being removed entirely from the outer cover.

Abstract: Provided is a method for preparing Rebaudioside J using an enzymatic method, comprising using rebaudioside A as a substrate, and making the substrate, in the presence of a glycosyl donor, react under the catalysis of a UDP-glycosyltransferase-containing recombinant cell and/or UDP-glycosyltransferase prepared therefrom to generate Rebaudioside J.

Abstract: In one aspect, a reconfigurable apparatus includes a first configuration, where the first configuration of the reconfigurable apparatus serves as a packaging box for a backpack. Specifically, the backpack may be folded and inserted inside the reconfigurable apparatus with the first configuration. The reconfigurable apparatus also includes a second configuration, where the second configuration of the reconfigurable apparatus serves as a structure for the backpack. Specifically, the reconfigurable apparatus with the second configuration can be inserted inside the backpack to provide an internal structure for the backpack.

Abstract: A printed circuit board for mounting electrical components thereupon include: a first side; a second side opposite the first side; electrical connection points disposed on the surface of an exterior edge of the printed circuit board; and wherein the exterior edge of the printed circuit board is between the first side and the second side. Further a method of manufacturing a printed circuit board for mounting electrical components thereupon includes the steps of disposing interconnect structures within the printed circuit board adjacent to at least one edge of the printed circuit board; and removing material from the printed circuit board edge to expose the interconnect structures such that the exposed interconnect structures correspond to a component connection footprint.

Abstract: Provided herein is a method of separating spandex from textile blends using biosolvents. The recovered material is of high purity while the chemical structure and molecular weight remain substantially unaffected by the treatment.

Abstract: Provided herein are amine-functionalized cellulose polymers useful for carbon dioxide capture and methods of preparation and use thereof.

Abstract: A printed circuit board structure is disclosed for providing reliable solderability for higher density component placement. The printed circuit board structure includes conductive points disposed on the surface of a printed circuit board which are separated by a channel disposed in the surface of the printed circuit board between the conductive points. The conductive points may be surface mount component terminal pads. The printed circuit board structure is particularly useful for overcoming component density limitations related to extremely miniaturized surface mount components known in the art.

Abstract: The present disclosure relates to methods for producing functional regenerated cellulose composite fibers and products thereof. The methods can be conducted with the use of recycled and/or virgin cellulose powder.

Abstract: A method for separating and recycling a waste polyester-cotton textile by a hydrothermal reaction catalyzed by an organic acid, comprising the following steps: dividing a waste polyester-cotton textile into fragments and dispersing in an aqueous solution system of the organic acid catalyst to obtain a mixed system; in a high-pressure reactor, heating the mixed system to 110˜180° C. so that cotton fibers in the waste polyester-cotton textile undergo a degradation reaction for 0.5˜3 h to obtain a mixture; and filtering the mixture by a sieve, washing to obtain a polyester fiber aggregate, and then filtering the remaining portion by a filtration membrane in vacuum so as to obtain cotton fiber fragments after washing. Embodiments of the present disclosure may provide advantages for the separation, recycling and reuse of waste polyester-cotton textiles. For example, the catalyst used during processing is derived from nature and is biodegradable.

Abstract: The present disclosure provides methods of preparing cellulosic superabsorbent polymer (SAP) using cellulose powder.
