Universal Approach for Predicting Crystallography of Heterogeneous Epitaxial Nanocrystals with Multiple Orientation Relationships
Heteroepitaxial nanocrystals
are one of the most fundamentally and technologically important classes
of materials systems. The correlation between form, dictated by crystallographic
features such as growth habit and direction, and function, in terms
of the ultimate physio-chemical properties is well established, thus
placing an onus on precise synthesis control of nanocrystal morphology.
Yet, nanocrystal heteroepitaxy can be a frustrating, time-consuming
iterative process, particularly during the initial stages of development.
What is desired is a powerful predictive tool that is able to successfully
predict not only the interface or habit plane, but also rationalize
the occurrence of epitaxial growth complexities such as multiple orientation
relationships (MORs) and high-index faceting planes for a diverse
range of materials. Here we provide such a powerful approach that
is based on an invariant deformation element (IDE) model, and fundamentally
founded on the crystallography of diffusional phase transformations.
We demonstrate its impact by detailed computations supported by transmission
electron microscopy evidence, for an archetypical complex metal oxide
nanocrystal system (that has up to five MORs for three differing growth
orientations). The method is then applied to successfully explain
growth for different materials ranging from metals to metal carbides
to transition metal oxides, even in thin film form. Thus, this relatively
simple yet powerful predictive guide significantly reduces the systemic
inefficiencies of guesswork and blind growth. Ultimately it can be
easily integrated with machine learning techniques toward reliable
and efficient advanced nanomaterials fabrication

Experimental validation of the miRNA targets.
<p>Cleavage sites were determined by the modified 5’RNA ligase-mediated RACE. Heavy black lines represent unigenes. miRNA complementary sites with the nucleotide positions of SPL and MYB cDNAs are indicated. Vertical arrows indicate the 5’ termini of miRNA-guided cleavage products, as identified by 5’-RACE, with the frequency of clones shown.</p
qRT-PCR validation of the differentially expressed miRNAs.
<p>Fold changes of the differentially expressed miRNAs are shown. miRNAs were analyzed using the poly(T) adaptor RT-PCR method. The levels in ZZN were arbitrarily set to 1. Error bars represent the standard deviations of three technical PCR replicates.</p
Two Sarcoviolins with Antioxidative and α‑Glucosidase Inhibitory Activity from the Edible Mushroom <i>Sarcodon leucopus</i> Collected in Tibet
Edible mushrooms are known as an
important source of natural antioxidants.
The ethyl acetate extract of the edible mushroom <i>Sarcodon
leucopus</i> (Zangzi mushroom) possesses strong antioxidative
activity. Bioactivity-guided isolation afforded 10 compounds from
its fruiting bodies, including two new sarcoviolins, sarcoviolin β
(<b>1</b>) and episarcoviolin β (<b>2</b>), and
one new <i>p</i>-terphenyl derivative (<b>3</b>) along
with seven known compounds. The structures of the new compounds were
elucidated by spectroscopic methods and comparison with the known
compounds. Compounds <b>1</b>–<b>10</b> were found
to have antioxidant effects in the DPPH scavenging assay, the total
antioxidant capacity assay, the reducing power assay, and the lipid
peroxidation assay. Further study indicated that they could protect
DNA strands from free radical-induced cleavage at 200 μM. Compounds <b>1</b>–<b>10</b> also presented strong α-glucosidase
inhibitory activity. Of all tested compounds, compound <b>1</b> exhibited the strongest inhibitory activity, with an IC<sub>50</sub> value of 0.58 μM
