This study aims to present an integrated process that can be used to produce biomedical and biological active components from the fruit shell of Abel. Through the Foss method, Aldehyde, acid compounds, acyl and alcohol compounds account for 22.7, 15.93, 0.24 and 61.13% of the extractives which were extracted from fruit shell by methanol solvents. Furfural, Pyrazole-4-carboxaldehyde, 1-methyl- and 5-Hydroxymethylfurfural account for 4.74, 1.22 and 58.78% of the extractives which were extracted from the fruit shell of Abel by ethanol solvents. Aldehyde, acid and amine compounds account for 5.01, 56.18 and 7.20% of the extractives which were extracted from the fruit shell of Abel by ethyl acetate solvents. The extractives of fresh flesh of bayberry were rich in rare drug, biomedical and biological activities.
Inspired
by the hierarchically ordered “brick and mortar”
(BM) architecture of natural nacre, in this study a rational assembly
of boron nitride (BN) nanosheets was introduced into a mixture of
trimethylolpropane triglycidyl ether (TTE) and soy protein isolate
(SPI), and a strong and multifunctional SPI-based nanocomposite film
with multinetwork structure was synthesized. At a low BN loading (<0.5%),
the resulting multifunctional film was flexible, antiultraviolet,
and nearly transparent and also displayed good thermal diffusion ability
and exhibited an excellent combination of high tensile strength (36.4
MPa) and thermal conductivity (TC, 2.40 W·m–1·K–1), surpassing the performances of various
types of petroleum-based plastics (displayed a tensile strength ranging
from 1.9 to 21 MPa and TC ranging from 0.55–2.13 W·m–1·K–1), including nine different
types of materials currently utilized for mobile phone shells, suggesting
its vast potential in practical applications.
We
used an innovative approach involving hot pressing, low energy
consumption, and no adhesive to transform bamboo biomass into a natural
sustainable fiber-based biocomposite for structural and furniture
applications. Analyses showed strong internal bonding through mechanical
“nail-like” nano substances, hydrogen, and ester and
ether bonds. The biocomposite encompasses a 10-fold increase in internal
bonding strength with improved water resistance, fire safety, and
environmentally friendly properties as compared to existing furniture
materials using hazardous formaldehyde-based adhesives. As compared
to natural bamboo material, this new biocomposite has improved fire
and water resistance, while there is no need for toxic adhesives (mostly
made from formaldehyde-based resin), which eases the concern of harmful
formaldehyde-based VOC emission and ensures better indoor air quality.
This surpasses existing structural and furniture materials made by
synthetic adhesives. Interestingly, our approach can 100% convert
discarded bamboo biomass into this biocomposite, which represents
a potentially cost reduction alternative with high revenue. The underlying
fragment riveting and cell collapse binding are obviously a new technology
approach that offers an economically and sustainable high-performance
biocomposite that provides solutions to structural and furniture materials
bound with synthetic adhesives.
Soy
protein isolate (SPI) is envisioned as a promising alternative
to fabricate “green” flexible electronics, showing great
potential in the field of flexible wearable electronics. However,
it is challenging to simultaneously achieve conductive film-based
human motion-monitoring strain sensors with reliable fatigue resistance,
robust mechanical property, environmental degradability, and sensing
capability of human motions. Herein, we prepared a series of SPI-based
nanocomposite films by embedding a surface-hydroxylated high-dielectric
constant inorganic filler, BaTiO3, (HBT) as interspersed
nanoparticles into a biodegradable SPI substrate. In particular, the
fabricated film comprising 0.5 wt % HBT and glycerin (GL), namely,
SPI–HBT0.5–GL0.5, presents multifunctional properties,
including a combination of excellent toughness, tensile strength,
conductivity, translucence, recyclability, and excellent thermal stability.
Meanwhile, this multifunctional film could be simply degraded in phosphate
buffered saline solution and does not cause any pollution to the environment.
Attractively, wearable sensors prepared with this particular material
(SPI–HBT0.5–GL0.5) displayed excellent biocompatibility,
prevented the occurrence of an immune response, and could accurately
monitor various types of human joint motions and successfully remain
operable after 10,000 cycles. These properties make the developed
SPI-based film a great candidate in formulating biobased and multifunctional
wearable electronics.
