Biopolymers with shape memory
The polylactic acid (PLA) family of polymers are made from plant-based oils and so are carbon-neutral; any carbon that they contribute to the environment has been extracted from the atmosphere by the growing plant. They can be
The difference of an amide to ester in polymers does the magic
一个ntibiotics kill bacteria by a specific targeting mechanism, and thereby, bacteria quickly develop resistance to antibiotics. The bacterial cell membrane is pivotal to its survival and is considered its Achille’s heel. Killing bacteria by attacking their cell
一个ll that powerful materials is not forever
Transient technology is foreseeable as a key ingredient for the development of emerging devices, especially for the sake of a sustainable human society. Scientists explore materials, devices and systems that are completely dissolved or selectively disintegrated at
Electrifying drug delivery
Most patients with chronic illnesses are treated with oral drugs and injections. These delivery methods are plagued by low drug efficacy and nonspecific side effects. In addition, studies estimate that as high as 60% of the patients
Towards better tissue regeneration: Improved vessel growth using synthetic polymers
The formation of vascular network is crucial for development and function of most of the tissues due to oxygen and nutrients supply and removal of toxic metabolites. In case of an injury such as bone or soft
Continuous fabrication of polymeric vesicles and nanotubes with fluidic channels
Wilson and coworkers reported a fluidic channel based strategy for fabricating different shaped polymeric vesicles. The formation of polymeric vesicles is based on the self-assembly of amphiphilic block polymer, which constitutes of a hydrophobic segment and a
团结就是力量的微观强度rmolecular connections
‘Unity is strength’ is one of the most overused motto in human societies, which found a plethora of validations since the ancient Greeks, via the French revolution, and up to the modern period. It is a common
Optimization of charge carrier transport balance for high efficient polymer solar cells
Polymer solar cells (PSCs) with poly (diketopyrrolopyrrole – terthiophene) (PDPP3T): [6,6] – phenyl – C71 – butyric acid methyl ester (PC71BM) as active layers were fabricated from different temperature solutions. The champion power conversion efficiency (PCE) of
Properties of magnetic nanocomposites for biomedical applications
Polymer nanocomposites have been receiving a lot of attention in the field of biomedical engineering. These composite materials, which consist of a polymer as the matrix and nanoparticles (nano-sized particles) as fillers, offer the opportunity for the
Photomultiplication type polymer photodetectors with broad spectral response range from UV light to NIR
Polymer photodetectors (PPDs) have attracted more and more attention due to the low cost, flexible and environment friendly and lighter weight compared to their inorganic counterpart. Up to now, most of the reported PPDs are photodiode type
Organic semiconductors for future photovoltaics
Organic semiconductors based photovoltaics devices are able to absorb light of different wavelengths and converted it into electricity or electrical signal. By converting the light into electricity, the organic solar cells represent a clean, cost-effective and easy
The thinner, the glassier
Polymers are a key component of our technologies. The diversity of uses and forms of these inexpensive materials is impressive: polymers are present in almost all the aspect of everyday life. Polymers are also intensively studied at
