Influence of nano confinement on nematic liquid crystals

open access: yes, 2012
We explore the nematic ordering of the rod-like liquid crystals 5CB and 6CB, embedded into parallel-aligned nanochannels in mesoporous silicon and silica membranes as a function of mean channel radius (4 ...

Robust and Thermally Stable Silicone Aerogels with Hyperconnected Network via Kinetically Optimized Hyperbranched Silane Precursors

open access: yesAdvanced Science, EarlyView.
Reactivity‐Programmed Assembly: A kinetic‐control strategy is reported for constructing hyperconnected silicone aerogels with a robust “thick‐neck” architecture. By exploiting the reactivity disparity of precursors, flexible segments are uniformly embedded within a rigid skeleton.

Role of Epoxide Functionalization of Amines for Development of Direct Air Capture Sorbents with High Cyclic Working Capacity at Low Desorption Temperatures

open access: yesAdvanced Science, EarlyView.
Appropriate butylene oxide (BO) functionalization of amines (polyethyleneimine (PEI1200 and PEI300) and tris(2‐aminoethyl)amine (TREN)) enables excellent cyclic working capacities (WCcyclic) at low desorption temperatures (40−70°C). Notably, 0.30BO‐PEI300‐SY and 0.54BO‐TREN‐SY show the highest WCcyclic at 45 and 40°C, respectively.

Advanced Dental Composite Technology via Bisilanized Dual‐Action Nanofillers for Biofilm Control

open access: yesAdvanced Science, EarlyView.
A multimodal research strategy has led to the development of an innovative resin‐based composite (RBC) with dual antibacterial action. The S_CM‐RBC formula showed strong antibiofilm activity, excellent mechanical strength, and biosafety. It effectively controlled oral bacteria in prevention of caries recurrence, and maintained pulp health in a rat ...

Reinforcing Oxygen Activation of Spinel Oxide via Mn─O Covalency Engineering for VOCs Oxidation

open access: yesAdvanced Science, EarlyView.
A MnCo spinel catalyst with weakened Mn─O covalency was synthesized via a hard‐template method. The reduced Mn─O covalency facilitates localized electron redistribution, promoting the activation of both molecular oxygen and lattice oxygen, and thereby enabling the efficient and complete oxidation of VOCs (ethyl acetate, toluene, and propane).

On fundamental mechanisms in dye sensitized solar cells through the behaviour of different mesoporous titanium dioxide films

open access: yes, 2015
Understanding mechanisms in DSSCs is fundamental for their improvement; this includes the nanocrystalline semiconducting layer behaviour. Different mesoporous TiO2 layers are fabricated and analyzed for possible use in DSSC solar cells.

Selenium‐Based Nanoplatforms: An Emerging Theranostic Paradigm for Gynecological Cancers

open access: yesAdvanced Science, EarlyView.
This reivew summarizes Selenium as a multifunctional anticancer regulator in gynecological cancers. It reduces tumor risk, enhances therapeutic efficacy, and reduces treatment toxicity. Selenium also overcomes chemoraditherapy resistance, improving overall treatment outcomes. ABSTRACT Gynecological cancers present significant therapeutic challenges due

Interface Wettability Transition‐Driven Drug Release and Dual‐Phase Functionalization in Implant Abutment

open access: yesAdvanced Science, EarlyView.
A temporally controlled drug release coating is developed for abutments using a superhydrophobic coating self‐assembled on mesoporous silica. This surface provides sequential functionality: initial contamination resistance through non‐wetting, followed by controlled drug release via wettability transition.
