Evaluation of Changes in Fold Cracking and Mechanical Properties of High-Grammage Paper Based on Pulp Fiber Modification

open access: yesBioResources, 2023
The demand for high-grammage paper, 150 g/m2 or more, is increasing for product protection and aesthetic value. Fold cracking, resulting from high mechanical pressure during folding, considerably decreases the economic feasibility of such products for ...

Quasi static analysis of creasing and folding for three paperboards [Elektronisk resurs]

open access: yes, 2013
The creasing and folding behavior of three paperboards have been studied both experimentally and numerically. Creasing and folding studies were performed on strips in both the machine direction and the cross machine direction. A finite element model that

Creasing studies in citrus [PDF]

open access: yes, 2010
Thesis (MScAgric (Horticulture))--University of Stellenbosch, 2010.ENGLISH ABSTRACT: Creasing, also known as albedo breakdown, is a preharvest disorder that affects the albedo of citrus fruit causing creases on the surface of the fruit.

Autonomous Folding of Soft Matter From Living Polymers

open access: yesAdvanced Materials, EarlyView.
Origami structures are endowed with “living” polymer creases that grow, remodel, and stiffen in response to nutrient solutions. This post‐fabrication growth enables autonomous folding, iterative regrowth, and mechanical tuning involving origami assemblies, such as cranes, Miura‐ori tessellations, rigid and non‐rigid square‐twist patterns, establishing ...

Evolution of OLED Lamination Technology With Development of Display Form Factors

open access: yesAdvanced Materials Technologies, EarlyView.
This review evaluates the evolution of organic light‐emitting diode (OLED) lamination technologies alongside advancing display form factors. It contrasts optically clear adhesives and resins, highlighting uniformity control for rigid screens, bubble‐free optimization for bended architectures, and visible‐light curing for foldable layers.
