Pinocembrin-7-O-β-D-glucoside (PCBG), a flavonoid isolated from Penthorum chinense Pursh., has significant liver-protecting effects. The pharmacokinetics of PCBG and its major metabolite pinocembrin (PCB) in rats were investigated in this study. A sensitive and accurate UPLC-MS/MS method was developed and validated fo…
Surfaces with patterned wettability contrast are important in industrial applications such as heat transfer, water collection, and particle separation. Traditional methods of fabricating such surfaces rely on microfabrication technologies, which are only applicable to certain substrates and are difficult to scale up a…
Abstract Here, we developed a highly sensitive label-free plasmonic crystal (PC). The PC is composed of two types of nanoperiodic metal structures, nanodiscs and nanohole arrays, fabricated simultaneously by nanoimprint lithography using a nanostructured polymer mold. The PC absorbed light at specific wavelengths base…
Abstract The surface chemistry and topography of biomaterials regulate the adhesion and growth of microorganisms in ways that are still poorly understood. Silicon nanograss structures prepared via inductively coupled plasma etching were coated with plasma deposited nanometer-thin polymeric films to produce substrates…
A hydrophobic/amino functionalized derivative of hyaluronic acid (HA‐EDA‐C18) has been processed by salt leaching technique as porous scaffold without need of chemical crosslinking. Aim of this work is to demonstrate the improved versatility of HA‐EDA‐C18 in terms of processing and biological functionalization. In par…
This research developed a viable and economical foaming formula (AOS/AVS/N70K-T) which is capable of creating ample and robust CO2 foams. Its foaming ability and displacement performance in a porous medium were investigated and compared with the two conventional formulations (AOS alone and AOS/HPAM). The results showe…
Using halogen-specific Connolly type molecular surfaces, we herein invented a new type of surface-based interaction analysis employed for the study of halogen bonding toward model systems of biologically relevant carboxylates (ASP/GLU) and carboxamides (ASN/GLN). Database mining and statistical assessment of the PDB r…
Pharmaceutical cocrystals of an analgesic drug ethenzamide (ETZ) with various coformers, namely, gallic acid (GA), 2-nitrobenzoic acid (2NB), 3-nitrobenzoic acid (3NB), 2,4-dinitrobenzoic acid (DNB), and 3-toluic acid (3TA) were synthesized by the solvent evaporation method. All the cocrystals were characterized by va…
Fe-encapsulated multiwall carbon nanotubes (Fe@MWCNTs) are candidates for magnetically targeted Drug Delivery Systems (mt-DDSs) against breast cancer. However, their full potential as versatile and biosafe vectors has yet to be developed. Key challenges that remain are relating surface functionalization to cytotoxicit…
This work finds that LiVO 3 is lithiated by a conversion reaction at 25 °C, which is unusual for the family of vanadium oxides. The spectroscopic studies and first-principle calculations performed on the lithiation mechanism of LiVO 3 consistently propose that a two-phase insertion-type lithiation proceeds in the earl…
A large swath of quantum critical and strongly correlated electron systems can be associated with the phenomena of preserved entropy and fragile magnetism. In this overview we present our thoughts and plans for the discovery and development of lanthanide and transition metal based, strongly correlated systems that are…
Hydrogenation of levulinic acid (LA) and its esters to produce γ-valerolactone (GVL) and 2-methyl tetrahydrofuran (2-MTHF) is a key step for the utilization of cellulose derived LA. Aiming to develop a commercially feasible base metal catalyst for the production of GVL from LA, with satisfactory activity, selectivity,…
A shaped-beam dual-band reflectarray (RA) with shared aperture is designed and simulated in this communication. Desired radiation patterns are considered squared cosecant and pencil beam in elevation and azimuth planes for both bands, respectively. This antenna has been designed to operate at X-Band (9.6–10.9 GHz) wit…
Schiff bases are considered `versatile ligands' in coordination chemistry. The design of polynuclear complexes has become of interest due to their facile preparations and varied synthetic, structural and magnetic properties. The reaction of the `ligand complex' [CuL] {H2L is 2,2'-[propane-1,3-diylbis(nitrilomethanylyl…
SolarBlack is a bone-char-based surface developed as a flat absorber (black) thermal control surface for use on spacecraft. The surface, originally developed for use on the front shield of “ESAs” Solar Orbiter, is deposited using a technique known as CoBlast, developed by ENBIO Ltd. The resulting surface makes use of…
In this report caffeine (CAF) co-crystallization with a fluoro-nitrobenzoic acid (F-NBA) yields a new solid form with superior tableting performance. A primary N···H–O synthon connects the basic nitrogen of CAF with the carboxylic acid of F-NBA to result in a layered structure with supportive CH 3 ···O interactions. O…
An experiment platform was established to study the measuring methods for the dynamic impedance characteristics of carbon fiber reinforced polymer (CFRP) under nondestructive lightning component A. On basis of the experimental results, the two‐electrode testing system was conducted and silicone grease was coated betwe…
AA-6061 (T6) aluminum alloy sheet is used extensively for structural applications in various automotive and aerospace industries due to its excellent mechanical and physical properties. Due to lower formability of this material in age-hardened (T6) condition, forming of complex-shaped components is a major challenge.…
Yttrium iron garnet (YIG, ${\mathrm{Y}}_{3}\mathrm{F}{\mathrm{e}}_{5}{\mathrm{O}}_{12}$) is a magnetic insulator that has been widely used to generate spin-wave spin current via the longitudinal spin Seebeck effect. Spin current can be converted to charge current by the inverse spin Hall effect (ISHE) in an attached m…
Magnetic tunnel junctions with perpendicular magnetic anisotropy are investigated using a conductive atomic force microscope. The $1.23\ensuremath{-}\mathrm{nm}$ ${\mathrm{Co}}_{40}{\mathrm{Fe}}_{40}{\mathrm{B}}_{20}$ recording layer coercivity exhibits a size dependence which suggests single-domain behavior for diame…
