1 Corn grain produced on fertile cropland is used for both human and livestock consumption. However, co-production of distiller’s grains notwithstanding, the use of corn grain and fertile cropland to produce fuel remains controversial, driving interest in cellulosic fuels generated from vegetative (non-grain) plant biomass (Biello, 2011; Wetzstein and Wetzstein, 2011; Bonin and Lal, 2012). Bioe...
Abstract Lignocellulosic materials with hydrophobic properties are of great interest for developing sustainable products that can be used in various applications such as packaging, water-repellent and self-cleaning materials, oil water separation or reinforcements biocomposite materials. The hydroxyl functional groups present cellulose provide the possibility to perform chemical modifications c...
Abstract Transient electronics offer a promising solution for reducing electronic waste and use in implantable bioelectronics, yet their fabrication remains challenging. We report on scalable method that synergistically combines chemical photonic mechanisms to sinter printed Zn microparticles. Following reduction of the oxide layer using an acidic solution, zinc particles are agglomerated into ...
Bamboo raw feedstocks with large particle size (20−80 mesh) were subjected to a microwave liquefaction system, and the liquefied products were separated into biopolyols and liquefied residues. Biopolyols were first analyzed by gas chromatography mass spectrometry (GC−MS), and the main components were sugar derivatives with 2−4 hydroxyl groups and phenolic compounds derived from lignin. The resi...
Contact angle methods are widely used to evaluate the wettability of cellulose-based surfaces and to judge their suitability for different applications. Wettability affects ink receptivity, coating, absorbency, adhesion, and frictional properties. There has been a continuing quest on the part of researchers to quantify the thermodynamic work of adhesion between cellulosic surfaces and various p...
The development of lignocellulose-derived sustainable plastics is an important strategy for a greener future. Cellulosic hydrogels, which are readily generated from a cellulosic source (e.g., wood pulp), can be converted into high-strength plastics by hot-pressing. In this process, cellulose macromolecules are fluidized and reassembled, leading to significant change of bonding interactions and ...
Thermophilic anaerobic noncellulolytic Thermoanaerobacter species are of great biotechnological importance in cellulosic ethanol production due to their ability to produce high ethanol yields by simultaneous fermentation of hexose and pentose. Understanding the genome structure of these species is critical to improving and implementing these bacteria for possible biotechnological use in consoli...
Enzymes are proteins that catalyse chemical reactions by lowering the activation energy needed and thus speed up the reaction itself. The advantage of enzymes is that they can be applied under mild reaction conditions and that they exhibit high substrate specificity, stereoselectivity and less side product formation than conventional chemical reactions, making biotechnological processes often m...
