Flexible and ultratransparent conductors based on graphene sheets have been considered as one promising candidate for replacing currently used indium tin oxide films that are unlikely to satisfy future needs due their increasing cost losses in conductivity bending. Here we demonstrate a simple fast electrochemical method exfoliate graphite into thin sheets, mainly AB-stacked bilayered with large lateral size (several several tens of micrometers). The electrical properties these exfoliated...
Ultra large and single-layer graphene oxide sheets (up to millimeter in lateral size) are obtained by a modified Hummers' method, where we replace the first aggressive oxidation process with short sonication step H2SO4 solutions. The size of GO can be adjusted period: it decreases increasing time. thin-film electrodes made from ultra reduced exhibit lower sheet resistance compared those small-size sheets. Moreover, transistor devices these after 800 °C thermal reduction effective hole...
Solution-based processes involving the chemical oxidation of graphite and reduction obtained graphene oxide (GO) sheets have attracted much attention for preparing films printed electronics biosensors. However, low electrical conductivity reduced GO is still hindering development electronic applications.

The transformation of PVDF from α-phase to β-phase makes more polar and decreases the crystallinity PVDF.
Abstract Tissue engineered heart valves (TEHVs) demonstrates the potential for tissue growth and remodel, offering particular benefit pediatric patients. A significant challenge in designing functional TEHV lies replicating anisotropic mechanical properties of native valve leaflets. To establish a biomimetic model, we employed melt-electrowriting (MEW) technology to fabricate an PCL scaffold. By integrating MEW-PCL scaffold with bioactive hydrogels (GelMA/ChsMA), successfully crafted elastic...
The dc magnetization, ac susceptibility, and isothermal remanent magnetization measurements are carried out for antiperovskite Mn3GaN. Strong indication a frozen state with freeing temperature of Tf at ∼133K is found, determined from the difference between field-cooled zero-field-cooled magnetizations. susceptibility show peak around Tf, position shifting as function driving frequency f magnetic field H, respectively. Relaxation effects observed after switching external below Tf. These...
Circulating tumor cells (CTCs) usually shed from primary and metastatic tumors serve as an important marker, easily cause fatal distant metastasis in cancer patients. Accurately effectively detecting CTCs a peripheral blood sample is of great significance early diagnosis, efficacy evaluation, postoperative condition monitoring. In this work, TiO2@Ag nanostructure structured SERS substrate, rhodamine 6G (R6G) used Raman signal molecule, the reduced bovine serum protein (rBSA) acts protective...
This study systematically investigates the synergistic effects of Cu addition (0–0.7 wt.%) and 2% pre-straining on artificial aging, natural aging (NA), bake-hardening response (BHR) AA6111 alloy. The results reveal that significantly enhances age-hardening capacity accelerates kinetics. 0.7Cu alloy achieved a 14% higher peak hardness (106.9 HV) than Cu-free (93.8 while reducing time by 50% (from 10 h to 5 h). Pre-straining further promoted hardening rates, shortening times 2 for Natural...
Circulating tumor cells (CTCs) can be the seeds of metastasis and are closely linked to cancer-related death. Fast effective detection CTCs is important for early diagnosis cancer evaluation micrometastasis. However, extreme rarity heterogeneity in peripheral blood make sensitive a big challenge.
