The narrowest host ranges, those in which a single microbial species affects only a singlehost species, appear to be derived from coevolutionary accommodations between microbe and host. Some of the fungal examples of such narrow host ranges include the species ofMassospora, azygomycetegenus in th...
Several reviews of biomass pretreatment applied to the process of biofuel production are available in literature, in which examples of common pretreatment methods include physical, chemical, biological pretreatments. For physical pretreatments, the main goal of these methods is to reduce the particle size...
In the future, this technique could be used in the laboratory to provide easy-to-access in situ information about the polymers. Even the state of biodegradable polymer implants could be wirelessly monitored. 机译:提出了一种监测水解过程中可生物降解聚合物变化的方法。这种无线无损方法基于嵌入聚合物...

Cross-linking results in much higher-molecular-weight polymers. Cross-linked polymers are unable to be truly dissolved because the cross-linking prevents the extension of individual chains and the subsequent surrounding bysolvent moleculesrequired forsolvation. Instead, cross-linked polymers are swollen in...
They can be fabricated using silicon, metals, biodegradable polymers, or carbohydrates. First-generation microneedles were solid microneedles that perforated the skin membrane and enhanced the permeability of drugs. Although solid microneedles appeared to be effective in delivering insulin [119], the ...
