A 3D‐Printed Model of Human Lactation

open access: yesAdvanced Healthcare Materials, EarlyView.
Breastfeeding supports infant and maternal health, yet in vitro models that mimic human lactation remain scarce. Here, light‐based 3D printing creates high‐resolution, alveoli‐inspired microwells that guide breast cells into polarized microtissues. The printed scaffolds embed slow‐release prolactin microcrystals to deliver hormonal cues, enabling human

Long-Term Drying Shrinkage Strain of Engineered Cementitious Composite Concrete Contains Polymeric Fibers

open access: yesJournal of Engineering
The lack of concrete tensile stress endurance led to the invention of engineered cementitious composite. However, the absence of gravel from the mixture in addition to the high binder content may lead to high shrinkage strain.

Experimental evaluation of drying shrinkage and mechanical properties of repair materials for concrete structures

open access: yes, 2007
The potentially aggressive environments in some parts of Saudi Arabia have resulted in premature deterioration of many concrete structures during their service performance life. To achieve more effective and long lasting repair materials, it is essential

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics

open access: yesAdvanced Materials, EarlyView.
“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.

Drying of persimmon: Mathematical model for diffusivity as a simultaneous function of moisture content and shrinkage

open access: yes, 2001
Fresh persimmon has a high moisture content (about 85% wet basis) making it highly perishable and requiring adequate drying conditions to obtain an acceptable dehydrated product. Drying kinetics of persimmon cv.

Physical properties of peat samples in relation to shrinkage upon drying.

open access: yesSilva Fennica, 1982
The study discusses the amount of shrinkage of volumetric undisturbed peat samples when drying to an oven-dry (105°C) condition. The amount of shrinkage is related to various physical properties of peat.

Drying shrinkage

open access: yes, 2019
The average values of drying shrinkage of CCGB at different ages (days 1, 3, 7, 14, 28, 45, and 60) and substitution rates (0, 10, 20, 30, and 40 wt%) were ...

Ferrocene‐Based Self‐Assembled Monolayers Enable Ultra‐High Specific Detectivity in Perovskite Photodetectors

open access: yesAdvanced Materials, EarlyView.
We report perovskite photodetectors with record specific detectivities exceeding 1013 Jones with a novel molecular design strategy to functionalize self‐assembled monolayers (SAMs) with ferrocene (Fc) derivatives. Fc‐SAM‐based devices also exhibit strong operational stability and enable data transmission rates exceeding 1 Mbps in a LiFi system ...

Multiphase transfer model for intermittent microwave-convective drying of food: Considering shrinkage and pore evolution [PDF]

open access: yes, 2017
Intermittent microwave convective (IMCD) drying is an advanced drying technology that improves both energy efficiency and food quality during drying. Although many experimental studies on IMCD have been conducted, there is no complete multiphase porous ...
