Optical-Cavity-Incorporated Colorful All-Solid-State Electrochromic Devices for Dual Anti-Counterfeiting.

The fusion of electrochromic technology with optical resonant cavities presents an intriguing innovation in the electrochromic field. However, this fusion is mainly achieved in liquid electrolyte-based or sol-gel electrolyte-based electrochromic devices, but not in all-solid-state electrochromic devices, which have broader industrial applications. Here, a new all-solid-state electrochromic device is demonstrated with a metal-dielectric-metal (MDM) resonant cavity, which can achieve strong thin-film interference effects through resonance, enabling the device to achieve unique structural colors that have rarely appeared in reported all-solid-state electrochromic devices, such as yellow green, purple, and light red.

Saving the overlooked mangrove horseshoe crabs-A perspective from enhancing mangrove ecosystem conservation.

Despite being widely distributed in Asia, Carcinoscorpius rotundicauda is often overlooked and, its population status remains unclear. Moreover, it is threatened by illegal harvesting and degradation of mangrove ecosystems. Protecting its habitat is essential for population and biodiversity conservation, as mangroves provide nursery grounds and food supply for C.

Rainbow-Colored Carbon Nanotubes via Rational Surface Engineering for Smart Visualized Sensors.

Surface engineering is effective for developing materials with novel properties, multifunctionality, and smart features that can enable their use in emerging applications. However, surface engineering of carbon nanotubes (CNTs) to add color properties and functionalities has not been well established. Herein, a new surface engineering strategy is developed to achieve rainbow-colored CNTs with high chroma, high brightness, and strong color travel for visual hydrogen sensing.

Colorful Electrochromic Displays with High Visual Quality Based on Porous Metamaterials.

The introduction of metamaterials into electrochromic (EC) displays has recently inspired a great breakthrough in the EC field, as this can offer a variety of new attractive features, from a very wide gamut of colors to very fast switching times. However, such metamaterial-based EC displays still face significant constraints when developing from single electrodes to full devices, because other supportive components in devices, such as counter electrodes and electrolytes, significantly affect light propagation and the subsequent perceived color quality in metamaterial-based EC devices. Herein, a new, cost-effective device design structured around a new type of porous metamaterial is reported to circumvent the critical problem in metamaterial-based EC displays.

Co-pyrolysis behavior of microalgae biomass and low-rank coal: Kinetic analysis of the main volatile products.

This work studied the kinetic characteristics of volatile products from co-pyrolysis of microalgae and low-rank coal. Iso-conversional method was applied to calculate the reaction order, activation energy and pre-exponential factor of gaseous products (H, CO, CH and CO) and benzene. The results indicated the activation energy of H generating from both individual and mixing samples was the highest, meaning H was the hardest to generate during the pyrolysis process.

On-line analysis on the interaction between organic compounds from co-pyrolysis of microalgae and low-rank coal: Thermal behavior and kinetic characteristics.

The interaction between organic compounds from microalgae and low-rank coal during the co-pyrolysis process was explored via thermogravimetric analyzer combined with an online mass spectrometer. The influence of Glycine (GLE) on thermal behavior and kinetic characteristics from gaseous products generation of mixtures of acid washed low-rank coal (ALC) were investigated. Positive and negative synergistic effects from the pyrolysis parameters and products distribution were observed due to the interaction between GLE and ALC.

Co-pyrolysis behavior of microalgae biomass and low-quality coal: Products distributions, char-surface morphology, and synergistic effects.

In this work, the distributions and releasing properties of the primary volatile products during co-pyrolysis of low-rank coal and green algae (GA) has been studied using fixed-bed reactor with online mass spectrometry. Surface morphology of the char was described quantitatively by SEM combined with fractal theory. Different forms of synergistic effects existed from both the yields of products and composition of the main gaseous products.

Imidazolone-amide bridges and their effects on tubulin polymerization in cis-locked vinylogous combretastatin-A4 analogues: synthesis and biological evaluation.

A series of novel combretastatin-A4 analogues in which the cis-olefinic bridge is replaced by an imidazolone-amide were synthesized, and their cytotoxicity and tubulin-polymerization inhibitory activities were evaluated. These compounds appear to be potential tubulin-polymerization inhibitors. Compounds 10, 9b and 9c, bearing 3'-NH₂-4'-OCH₃, 4'-CH₃ and 3'-CH₃-substituted 1-phenyl B-ring, confer optimal bioactivity.

Synthesis and antifungal activities of novel 2-aminotetralin derivatives.

Novel 2-aminotetralin derivatives were synthesized as antifungal agents. The 2-aminotetralin scaffold was chemically designed to mimic the tetrahydroisoquinoline ring of the lead molecule described before. Their antifungal activities were evaluated in vitro by measuring the minimal inhibitory concentrations (MICs).

Design, synthesis, and antifungal activities of novel 1H-triazole derivatives based on the structure of the active site of fungal lanosterol 14 alpha-demethylase (CYP51).

A series of fluconazole (1) analogues, compounds 3a-k, were prepared as potential antifungal agents. They were designed by computational docking experiments to the active site of the cytochrome P450 14alpha-sterol demethylase (CYP51), whose crystal structure is known. Preliminary biological tests showed that most of the target compounds exhibit significant activities against the eight most-common pathogenic fungi.

Construction of a three-dimensional pharmacophore for Bcl-2 inhibitors by flexible docking and the multiple copy simultaneous search method.

B-Cell lymphoma-2 (Bcl-2) protein is a new promising target for anticancer drugs. A number of anticancer Bcl-2 inhibitors with diverse chemical structures have been discovered in recent years. In this paper, the flexible docking was performed to determine the binding modes of the representative inhibitors from different structural types.
