To date there have been no studies investigating the characteristics of pain in Chinese heroin-dependent patients (HDPs) receiving methadone maintenance treatment (MMT). This study examined the frequency and socio-demographic and clinical correlates of pain in HDPs under MMT. A consecutive sample of 603 HDPs was recruited from three MMT clinics in Wuhan, China. These patients completed a standardized questionnaire concerning socio-demographic and clinical data. Pain intensity was assessed with the 5-point Verbal Rating Scale ("Overall, how intense is your pain now?") with responses of: 1 = none, 2 = mild, 3 = moderate, 4 = severe, 5 = very severe...

Constructing methods for cleaning stains on paper artworks that meet the requirements of preservation of cultural relics are still challenging. In response to this problem, a novel electrochemical cleaning method and the preparation of corresponding electrodes were proposed. For this purpose, the conductive graphene (rGO)/polyacryamide (PAM)/montmorillonite (MMT) composite hydrogel as cathode and PbO2-based material as anode were prepared and characterized. The electrochemical cleaning efficiencies of real sample and mimicking paper artifacts were evaluated, and the effects of the electrochemical cleaning on paper itself were detected...

Banana flour film is an alternative biopolymer material but still needs improvement of its mechanical properties and water vapor permeability. Banana starch nanoparticles (BSNs), prepared using miniemulsion cross-linking, make an interesting reinforcing agent. The properties of plasticized banana flour film (PBF) were characterized incorporated with 5% (w/w) of either montmorillonite; MMT-Na(+) (PBF-M) or BSN (PBF-B), including a mixture of nanoparticles at 1:1 for 5% (PBF-MB5) and 10% (PBF-MB10). PBF-MB5 provided better improvement in the film mechanical and water barrier properties compared with PBF-B...

Montmorillonite (MMT) was added to silicone rubber (SR) to improve the ablation resistance of the silicone. Following this, different quantities of silicon carbide whiskers (SiCw) were incorporated into the MMT/SR to yield a hybrid, ablative composite. The tensile strength and elongation at break of the composite increased after the addition of MMT. The ablation test results showed that MMT helped to form a covering layer by bonding with the silica and other components on the ablated surface. The linear and mass ablation rates exhibited decreases of 22...
