Porosity and surface area analysis play a prominent role in modern materials science. At the heart of this sits Brunauer-Emmett-Teller (BET) theory, which has been remarkably successful contribution to field The BET method was developed 1930s for open surfaces but is now most widely used metric estimation areas micro- mesoporous materials. Despite its widespread use, calculation causes spread reported areas, resulting reproducibility problems both academia industry. To prove this, analysis,...
Abstract Graphene oxide (GO)—the oxidized form of graphene—is actively studied in various fields, such as energy, electronic devices, separation water, materials engineering, and medical technologies, owing to its fascinating physicochemical properties. One major drawback GO is instability, which leads the difficulties product management. A understanding ever-changing nature can remove barrier for growing applications. Here, we evidencde presence intrinsic, metastable transient states upon...
The efficient separation of hydrogen from methane and light hydrocarbons for clean energy applications remains a technical challenge in membrane science. To address this issue, we prepared graphene-wrapped MFI (G-MFI) molecular-sieving the ultrafast at permeability reaching 5.8 × 10

A Zn–Al dispersed SWCNT based Superhydrophobic Strain Sensor offers highly linear piezoresistive-response, providing a new vista for infrastructure and health monitoring.
Hydrophilic interaction liquid chromatography (HILIC) has been widely applied to challenging analysis in biomedical and pharmaceutical fields, bridging the gap between normal-phase high-performance reversed-phase (RP-HPLC). This paper comprehensively explores retention mechanisms of amitriptyline its impurities A, B, C, D, F, G on amide, amino, diol, silica columns. Dual HILIC/RP-HPLC were developed, transitional points HILIC RP-HPLC calculated Adsorption partition contributions overall...

We report a route for opening nanowindows on graphene wall of single carbon nanohorn (SWCNH) aided by copper (II) 2,3,9,10,16,17,23,24-octakis (octyloxy)-29H, 31H-phthalocyanine (CuPc), which acts as catalyst nanowindow formation. CuPc is adsorbed SWCNH from liquid phase and heat treated in oxygen atmosphere to produce the adsorption sites CuPc. The isotherms N2 Ar CuPc-adsorbed heat-treated have low pressure hysteresis. hysteresis gap amount difference between desorption branches reaches...
Propranolol hydrochloride, a non-cardio-selective beta blocker, is used to treat several conditions in children, including hypertension, arrhythmias, hyperthyroidism, hemangiomas, etc. Commercial liquid formulations are available Europe and the US, but they have disadvantages, such as limited stability, bitter taste, need for multiple daily doses due drug’s short half-life. Considering these limitations, controlled-release solid formulations, microparticles, may offer better solution...
Nanoporous Materials In article number 2201502, David Fairen-Jimenez and co-workers conduct a round-robin exercise by providing 18 already-measured adsorption isotherms to sixty-one labs show that the reproducibility of Brunauer–Emmett–Teller (BET) area determination in micro- mesoporous materials remains largely ignored issue. To solve this, new computational approach—called BETSI—that expands on Rouquerol criteria makes an unambiguous BET assignment possible is developed.
Naphthalene (N) or naphthalene-derivative (ND) adsorption-treatment evidently varies the electrical conductivity of single wall carbon nanotube (SWCNT) bundles over a wide temperature range due to charge–transfer interaction. The adsorption treatment SWCNTs with dinitronaphthalene molecules enhances SWCNT by 50 times. dependence N- ND-adsorbed having superlattice structure suggests metal–semiconductor transition like behavior near 260 K. gives maximum in logarithm <italic>vs....
Newly developed inorganic single-wall carbon nanotube (SWCNT) inks of the Zn/Al complex and colloidal silica give a quite homogeneous SWCNT film on polyethylene terephthalate (PET) substrate by bar-coating method, whereas surfactant-based sodium dodecyl sulfonate (SDS) benzene (SDBS) cannot film. The key properties were studied for production films. contact angle surface tension dispersant-based 70° 72 mN m(-1), respectively, being close to those water (71.5° 71 m(-1)). viscosity was...
The controlled production of nanowindows in graphene layers is desirable for the development ultrathin membranes. Herein, we propose a single-atom catalytic oxidation method introducing into single-walled carbon nanotubes (SWCNTs). Using liquid-phase adsorption, copper(II) 2,3,9,10,16,17,23,24-octakis(octyloxy)-29H,31H-phthalocyanine (CuPc) was adsorbed on SWCNT bundles at surface coverage 0.9. Subsequently, narrow with number density 0.13 nm–2 were produced by above 550 K, which higher than...
Structural characterization of porous carbon materials is critical for the evaluation their synthesis procedures and performance. Throughout last decades, many methods have been employed to determine porosity properties from gas adsorption such as surface area, pore size distribution (PSD) real density. However, models use 1D structures nanopores, although separation nanoporous carbons are governed by 3D parameters. Estimating nanostructure using would accelerate progress in research...
