Summary: Polymer dispersed liquid crystals (PDLCs) containing ODA-SWCNT dispersions were prepared and their electro-optical properties were studied. Compared to pure PDLCs, the PDLCs with ODA-SWCNT dispersions showed a shorter response time, lower threshold voltage, higher optical transparency, and better image sharpness in the ON-state.

Summary: To achieve fast and sensitive detection of proteins, researchers have developed a polymer-sorted high-purity semiconducting carbon nanotubes (CNTs) films-based field-effect transistor (FET) biosensor for ultrasensitive and label-free detection of MUC1, a transmembrane protein highly expressed in breast cancer exosomes. The modified CNT FET was capable of sensitively and selectively detecting exosomal MUC1 as low as 0.34 fg/mL, and it could differentiate breast cancer patients from healthy individuals by comparing the expression level of exosomal MUC1. This novel CNT FET biosensor holds great potential for early diagnosis of cancer.

Summary: By dispersing metallic-phase MoS2 uniformly on functionalized carbon nanotubes through a solvothermal approach, a 1D@2D hierarchical architecture with strong covalent interface interaction and improved electronic conductivity was achieved. The resulting CNT@1T-MoS2 electrode exhibited outstanding sodium-storage performance, retaining high capacity even at large current densities and showing good stability and fast-charging capability in lithium storage. This work demonstrates the effectiveness of controlling phase structure and interface interaction in enhancing the performance of transition-metal dichalcogenide-based composite electrodes for energy storage applications.

Summary: This study investigates the use of carbon nanotubes (CNTs) as additives to enhance the bonding strength between concrete and carbon fiber reinforced polymer (CFRP). By adding different types and weight percentages of CNTs to epoxy, single-shear tests were conducted to analyze the bonding behavior. The results show that a certain proportion of CNTs modified epoxy can improve the bonding strength and interfacial fracture energy.

Summary: The tunneling resistance in polymer nanocomposites is influenced by factors such as tunneling distance, percolation onset, CNT content, and CNT curliness. Other factors like the portion of attached CNTs, CNT conductivity, CNT length, interphase depth, CNT radius, and interfacial tension also play a role in determining the tunneling resistance.

Summary: Functionalizing carbon nanotubes with DNA strands in a helical manner can polarize carrier spins through the CISS effect. The conduction mechanism is strongly localized due to DNA functionalization, and the observed magnetoresistance arises from interference effects between different hopping paths. CISS-induced spin polarization increases carrier localization length significantly in the low temperature range, impacting magnetoresistance in a non-trivial way not seen in conventional systems.

Summary: The unique electronic and vibrational properties of linear carbon chains (LCCs) have attracted attention recently. Raman spectroscopy has been widely used to identify LCC and study its properties. This study investigates the optical resonance window of LCCs encapsulated by multi-walled carbon nanotubes (MWCNTs) and a Raman signature assigned to the LCC's longitudinal acoustic phonon mode. First-principles calculations support the conclusions.

Summary: This study successfully obtained electrically conductive materials by adding functionalized multiwalled carbon nanotubes, and confirmed that carbon nanotubes as polymer reinforcements can increase tensile strength and strain percentage. However, increasing nanofiller percentages resulted in a drastic decrease in Young's modulus values.

Summary: The study focuses on the in-situ assembly of carbon nanotubes (CNTs) using macroscopic dielectrophoresis, overcoming the limitation of small size in traditional manipulation methods. Through optimizing voltage and frequency, ordered CNTs chains can be obtained under the action of alternating current dielectrophoresis, which can restore immediately upon powering up after being damaged. Different conductive patterns on non-woven fabric can be achieved by controlling the position of the electrodes in a wet environment.

Summary: The interaction between carbon nanotubes (CNTs) and graphene oxide (GO) was studied experimentally and computationally. It was found that the addition of GO can effectively improve the dispersibility of CNTs. The epoxy group and hydroxyl group have a significant impact on the dispersibility of CNTs. The dispersion effect of GO on ac-CNT is more pronounced, and the contact area between GO and CNT has a significant influence on the interaction.

Summary: The Lebedev process involves converting ethanol to butadiene catalytically, with silica-magnesia being a key catalyst for this process. Different preparation methods impact the performance of the catalyst, with wet-kneading resulting in the formation of surface magnesium silicates. The calcination temperature plays a significant role in determining the type of magnesium silicates formed, which in turn affects the catalytic properties and product formation.
