Map images are composed of semantic layers depicted in arbitrary color. Often images require separation into layers for storage and processing. Separation results in severe artifacts because of layer overlapping. In the current work, we design the technique to restore semantic layers after separation. The designed restoration technique alleviates compression deficiency of reconstructed layers v...

Selective filtration of gas, water, and liquid or gaseous oil is essential to prevent possible environmental pollution and machine/facility malfunction in oil-based industries. Novel materials and structures able to selectively and efficiently filter liquid and vapor in various types of solutions are therefore in continuous demand. Here, we investigate selective gas-water-oil filtration using t...

Microdroplets show great promise as a new high-throughput technology in chemistry, biochemistry, and molecular biology. Microdroplets can be generated at rates in excess of several thousands per second and accurately formulated using minute amounts of small molecules, DNA, proteins, or cells. Furthermore, integrated active elements can be used to control individual droplets. With the technology...

The feasible, reliable and selective multi-template molecularly imprinted polymers (MT-MIPs) based on SBA-15 (SBA-15@MT-MIPs) for the selective separation and determination of the trace level of ginsenoside Rb1 (Rb1), ginsenoside Rg1 (Rg1) and notoginsenoside R1 (R1) simultaneously from biological samples were developed. The polymers were constructed by SBA-15 as support, Rb1, Rg1, R1 as multi-...

The feasible, reliable and selective multi-template molecularly imprinted polymers (MT17 MIPs) based on SBA-15 (SBA-15@MT-MIPs) for the selective separation and determination of the 18 trace level of ginsenoside Rb1 (Rb1), ginsenoside Rg1 (Rg1) and notoginsenoside R1 (R1) (Panax 19 notoginseng saponins, PNS) from biological samples were developed. The polymers were 20 constructed by SBA-15 as s...

We unveil a unique kinetic driven separation material for selectively removing linear paraffins from iso-paraffins via a molecular sieving mechanism. Subsequent carbonization and thermal treatment of CD-MOF-2, the cyclodextrin metal-organic framework, afforded a carbon molecular sieve with a uniform and reduced pore size of ca. 5.0 Å, and it exhibited highly selective kinetic separation of n-bu...

Based on the different oxidation potentials of endohedral fullerenes Sc3N@C80 Ih and D5h and Sc3N@C78, an efficient and useful method that avoids HPLC has been developed for their separation. Selective chemical oxidation of the Sc3N@D5h-C80 isomer and Sc3N@C78 by using an acetylferrocenium salt [Fe(COCH3C5H4)Cp](+) followed by column chromatographic separation and reduction with CH3SNa resulted...

Recent studies report promising results regarding extracorporeal magnetic separation-based blood purification for the rapid and selective removal of disease-causing compounds from whole blood. High molecular weight compounds, bacteria and cells can be eliminated from blood within minutes, hence offering novel treatment strategies for the management of intoxications and blood stream infections. ...

A simple reversed-phase chiral HPLC method has been developed and validated for direct separation of the enantiomers of zaltoprofen. Separation of the enantiomers was tested on numerous commercial chiral HPLC columns. Separation was best (resolution, RS = 3) on a Chiralcel OJ-RH stationary phase. Typical retention times of the S and R enantiomers were approximately 14 and 16 min, respectively. ...

Selective ion separation via capacitive deionization (CDI) is of relevance because its environmental and industrial applications in water purification softening, heavy metal removal, resource recovery. Conventionally, carbon electrodes ion-selective membranes have been used for selective removal anions cations. In this study, we engineered a CDI cell with two identical NiHCF electrodes, separat...
