Catalytic Nucleic Acids: Biochemistry, Chemical Biology, Biosensors, and Nanotechnology
(Elsevier, 2020-01)Since the initial discovery of ribozymes in the early 1980s, catalytic nucleic acids have been used in different areas. Compared with protein enzymes, catalytic nucleic acids are programmable in structure, easy to modify, ... -
Cellulose nanocrystals in smart and stimuli-responsive materials: a review
(Elsevier, 2020-03)“Smart” stimuli-responsive materials have been the subject of decades of research because of their versatility and particularly their use in medical and sensing applications. While these materials are often composed ... -
Tunable covalent organic framework electrochemiluminescence from non-electroluminescent monomers
(Elsevier, 2021-10)It is hard to find new electrochemiluminescence (ECL) luminophores using existing research strategies, especially from ECL non-active monomers. Here, fully conjugated covalent organic frameworks with trithiophene (BTT-COFs) ... -

Self-Assembly of Amphiphilic Nanoparticle-Coil “Tadpole” Macromolecules
(American Chemical Society, 2004)There has been considerable fascination with the self-assembling behavior of amphiphilic chainlike molecules that range from short-chain surfactants to high molecular weight block copolymers. The self-assembly of simple ... -
Origins of Elastic Properties in Ordered Block Copolymer/Nanoparticle Composites
(American Chemical Society, 2004)We predict a diblock copolymer melt in the lamellar phase with added spherical nanoparticles that have an affinity for one block to have a lower tensile modulus than a pure diblock copolymer system. This weakening is due ... -
Ordering mechanisms in triblock copolymers
(American Physical Society, 2004)The ordering mechanisms for an ABC triblock copolymer system are studied using self-consistent field theory. We find a two-phase mechanism, similar to what has been suggested experimentally two-step mecha- nism. Analysis ... -
Evaluating Characteristic Parameters for Carbon Dioxide in the Sanchez−Lacombe Equation of State
(American Chemical Society, 2017)For many different pure substances, large numbers of competing characteristic parameter sets exist in the literature for the Sanchez−Lacombe equation of state. This is due in part to differing research requirements or ... -
Effect of well-dispersed surface-modified silica nanoparticles on crystallization behavior of poly (lactic acid) under compressed carbon dioxide
(Elsevier, 2016)In this work, the crystallization behavior of poly (lactic acid) (PLA)/amine-modified silica nano- composites at different loadings of amine-modified silica (1, 2, and 8 wt %) under isothermal, non- isothermal, and isothermal ... -
Polymeric Foaming Predictions from the Sanchez-Lacombe Equation of State: Application to Polypropylene-Carbon Dioxide Mixtures
(American Physical Society, 2017)A simple off-lattice method of deriving the Sanchez-Lacombe equation of state is presented. The Sanchez-Lacombe equation of state for mixtures is shown to be thermodynamically inconsistent for all mixing rules in such a ... -
Application of a constant hole volume Sanchez–Lacombe equation of state to mixtures relevant to polymeric foaming
(Royal Society of Chemistry, 2018)A variant of the Sanchez–Lacombe equation of state is applied to several polymers, blowing agents, and saturated mixtures of interest to the polymer foaming industry. These are low-density polyethylene– carbon dioxide and ... -
Wetting, adhesion and droplet impact on face masks
(ACS, 2021-02-12)In the present pandemic time, face masks are found to be the most effective strategy against the spread of the virus within the community. As aerosol-based spreading of the virus is considered as the primary mode of ... -
Microparticle suspensions and bacteria laden droplets: Are they the same in terms of wetting signature?
(ACS, 2021-01-17)Adhesion behavior of microbial pathogens on commonly encountered surfaces is one of the most pertinent questions now. We present the characterization of bacteria laden droplets and quantify the adhesion forces on highly ... -
Friction and Adhesion of Microparticle Suspensions on Repellent Surfaces
