Structural characterization and optimum machining parameters of jute/carbon fibre hybrid reinforced epoxy composite laminates

open access: yesPolymer International, EarlyView.
Hybrid jute/carbon epoxy laminates have better mechanical performance and less drilling damage by the use of optimized stacking sequence and machining parameters. Abstract Three composite laminate systems were produced using the standard hand lay‐up method: jute‐fibre‐reinforced polymer (JFRP), carbon‐fibre‐reinforced polymer (CFRP) and a hybrid of the

Isolation of Cellulose Nanofibers: Effect of Biotreatment on Hydrogen Bonding Network in Wood Fibers

open access: yesInternational Journal of Polymer Science, 2011
The use of cellulose nanofibres as high-strength reinforcement in nano-biocomposites is very enthusiastically being explored due to their biodegradability, renewability, and high specific strength properties. Cellulose, through a regular network of inter-

Bioconversion and characterization of watermelon rind waste‐based microcrystalline cellulose: A green alternative to synthetic reinforcements

open access: yesPolymer International, EarlyView.
Microcrystalline cellulose (MCC) was extracted from watermelon rind using acid hydrolysis. MCC can be efficiently used as reinforcement in biofilms and biocomposites. Abstract The increasing accumulation of agricultural waste from watermelon (Citrullus lanatus) represents a substantial environmental concern, particularly in view of the extensive ...

Vertex-element models for anisotropic growth of elongated plant organs

open access: yesFrontiers in Plant Science, 2013
New tools are required to address the challenge of relating plant hormone levels, hormone responses, wall biochemistry and wall mechanical properties to organ-scale growth. Current vertex-based models (applied in other contexts) can be unsuitable for

Deciphering Branched Galactomannan Structures via Multistage Ion Mobility MS and MSn Fragmentation (Multistage IMSn)

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Hemicelluloses are abundant carbohydrate components in plant cell walls. They play a crucial structural role in binding cellulose microfibrils, in addition to other biological functions. Their high structural variability directly influences their biological properties, making it important to establish a structure–function ...

Clinically‐Relevant Static Magnetic Field Induces Release of Encapsulated Molecules from Magnetoliposomes

open access: yesSmall, EarlyView.
This work demonstrates the feasibility of a molecule release from magnetoliposomes triggered by a constant 1.5 T magnetic field currently used in clinical settings. ABSTRACT Magnetoliposomes (MLs) are known for their great potential in drug release under an alternating current (AC) magnetic field (MF).

Ultrastructural properties of ciliary zonule microfibrils

open access: yesJournal of Structural Biology, 2002
Conventional electron microscopy and rotary shadowing techniques have provided conflicting interpretations of microfibril ultrastructure. To address this issue, we have used quick-freeze deep-etch (QFDE) microscopy to obtain 3-dimensional surface views of microfibrils that have not been fixed, dehydrated, or stained with heavy metals. By this approach,

Extraction of 2D Cellulose Nanosheets From Natural Cellulose

open access: yesSusMat, EarlyView.
2D cellulose nanosheets can be selectively extracted from various natural cellulose via precise breaking of their structure using a zwitterion combined solid catalyst. This provides direct evidence of 2D arrangement and challenges the classical fibrillar model, prompting a redefinition of cellulose hierarchy.
