Unlock the Walnut: How a Pectin‐Rich Suture Tissue and Moisture‐Driven Crack Formation Induce Shell Splitting and Facilitate Seed Germination

open access: yesAdvanced Functional Materials, EarlyView.
Walnut seeds are enclosed in a remarkably strong shell made of sclerenchyma, separated by a pectin‐rich suture tissue. Different cell shapes and chemical composition of this tissue point to an opening mechanism, which is triggered by cyclic humidity changes.

Colloidal Opaline Composites as Throughput‐Scalable, Fully Transparent, and Color‐Tunable Radiative Cooling Exterior Films for Outdoor Photovoltaics

open access: yesAdvanced Functional Materials, EarlyView.
Particular thermal metamaterials are widely used as daytime radiative coolers merely by embedding thermally emissive nanoparticles (NPs) in liquid resins to form scalable, yet highly efficient cooling films in a cost‐effective way. However, randomly dispersed NPs, prevalently used thus far, cause strong scattering, limiting NP content and cooling ...

De novo transcriptome analysis of Sinapis alba in revealing the glucosinolate and phytochelatin pathways

open access: yesFrontiers in Plant Science, 2016
Sinapis alba is an important condiment crop and can also be used as a phytoremediation plant. Though it has important economic and agronomic values, sequence data and the genetic tools are still rare in this plant.

Enhancing the Photocatalytic Performance of Carbon Nitrides Through Controlled Local Structure Modification

open access: yesAdvanced Functional Materials, EarlyView.
This work utilizes poly(heptazine imides) as a model system to demonstrate how fine‐tuning the crystal structure influences the photocatalytic properties of layered carbon nitrides in the hydrogen evolution reaction. In particular, the nature of rotational defects and the hydration shell of cations are key contributors to enhanced hydrogen evolution ...

Cat‐Vibrissa‐Inspired Biomass Fiber Aerogels for Flexible and Highly Sensitive Sensors in Monitoring Human Sport

open access: yesAdvanced Functional Materials, EarlyView.
Inspired by cat vibrissae, biomimetic biomass PHFs/SA aerogels (BFAs) are developed via precursor‐assisted in situ polymerization and freeze‐synergistic assembly. These ultralight, porous pressure sensors exhibit high sensitivity and excellent durability, enabling pulse detection, handwriting recognition, Morse code transmission, and notably real‐time ...

Efficient transformation of the isolated microspores of Chinese cabbage (Brassica rapa L. ssp. pekinensis) by particle bombardment

open access: yesPlant Methods
Background The low efficiency of genetic transformation in Chinese cabbage (Brassica rapa L. ssp. pekinensis) is the key problem affecting functional verification. Particle bombardment is a widely used method along with the Agrobacterium-mediated method.

Colorful flowers

open access: yesTopology and its Applications, 2008
AbstractFor a set A let [A]k denote the family of all k-element subsets of A. A function f:[A]k→C is a local coloring if it maps disjoint sets of A into different elements of C. A family F⊆[A]k is called a flower if there exists E∈[A]k−1 so that |F∩F′|=E for all F,F′∈F, F≠F′. A flower is said to be colorful if f(F)≠f(F′) for any two F,F′∈F.
