... Flux synthesis is an effective method to discover large crystals of new compounds. In this paper, a solid-state reaction in Li flux produced a new nitridolithosilicate La₄Ba₃Li₃Si₉N₁₉ in the orthorhombic space group Cmcm (No. 63) with lattice parameters of a = 9.7263(1), b = 18.2746(2), c = 11.2929(1) Å, and Z = 4. The La₄Ba₃Li₃Si₉N₁₉ exhibits a 3-D framework based on triangular clusters (3-rings) ...

Abstract:
... Although smectite-type clays are used as heterogeneous media for photofunctional guest molecules, the guest species are limited to cationic or polar molecules because of the intrinsic negative electric charges of clay particles. Nevertheless, in this study, aqueous clay colloids are reported to affect the photoisomerization kinetics of anionic and cationic azobenzene molecules dissolved in the col ...

Abstract:
... Inspired by the stomatal feature of plant leaves, a photo-responsive membrane was developed to enhance the removal of irreversible membrane fouling and to control molecule release. Photo-responsive polymers were prepared by reacting the amine group of 4-amineazobenzene with about 3, 5 and 9 out of 12 carboxylic groups of PMAA which was grafted from P(VDF-CTFE) with a certain length. Subsequently, ...

Abstract:
... In this work, the UV₂₅₄/H₂O₂ process was utilized to remove β-N-methylamino-l-alanine (BMAA), a kind of cyanobacteria neurotoxin, and the influence of reaction parameters and environmental factors on the degradation of BMAA has been systematically investigated. The results showed that BMAA could be effectively removed in the UV₂₅₄/H₂O₂ system compared to UV or H₂O₂ alone and OH was confirmed as th ...

Abstract:
... In-plane anisotropy of two-dimensional materials remains one of the most attracting properties. By employing first-principles calculations, we systematically explore the electronic, carrier transport, and optical properties of monolayer and bilayer titanium trisulfide (TiS₃). They are predicted to be direct semiconductors with eligible bandgap of about 1.4 eV. The two systems have high charge carr ...

Abstract:
... Platelet granules contain a diverse group of proteins. Upon activation and during storage, platelets release a number of proteins into the circulation or supernatant of stored platelet concentrate (PC). The aim of this work was to investigate the effect of pathogen inactivation (PI) on a selection of proteins released in stored platelets. Materials and Methods: PCs in platelet additive solution (P ...

Abstract:
... Organic ultralong room temperature phosphorescence (OURTP) materials having stimuli-responsive attributes have attracted great attention due to their great potential in a wide variety of advanced applications. It is of fundamental importance but challengeable to develop stimuli-responsive OURTP materials, especially such materials with modulated optoelectronic properties in a controlled manner pro ...

Abstract:
... The instability of perovskite optoelectronic devices remains a big barrier to their commercialization. The instability caused by external stimuli has been addressed by encapsulation, such as humidity, oxygen, heat, and ultraviolet light. However, the intrinsic instability of perovskite materials due to the lattice strain has not been fully addressed, which affects the physical properties and devic ...

Abstract:
... Pyridine and its derivatives are widely consumed and detected in the environment persistently, which can cause potential adverse impacts on environment and human health. Considering the fact that pyridine could absorb UV light at 254 nm to generate excited one, which could react with reductive radicals, promoting its structural changes, we proposed that one typical efficient advanced reduction pro ...

Abstract:
... Plastic pollution, particularly non-degradable residual plastic films and microplastics (MPs), is a serious environmental problem that continues to worsen each year. Numerous studies have characterized the degradation of plastic fragments; however, there is known a lack of about the state of current physicochemical biodegradation methods used for plastics treatment and their degradation efficiency ...

Abstract:
... Natural dyes are highly promising alternatives; however, their use has some drawbacks such as low light fastness, color yield, and repeatability. The objective of this study is to improve the light fastness of natural dyes. For this objective, wool fabrics dyed with pomegranate peels were subjected to different chemical treatments and UV curing. An important conclusion of this work is that UV curi ...

Herein, we report an efficient approach of self-assembling MoO₃–ₓ QDs on MXene (Ti₃C₂Tₓ) to fabricate multifunctional polyester fabrics. In a typical preparation, MoO₃–ₓ QDs with an average size of 5 nm were uniformly distributed on the surface o ...

Abstract:
... An efficient one-pot synthesis of imidazo[1,2-a]pyridines from 2-bromoazirines and pyridines has been developed. The construction of the bicyclic framework of imidazo[1,2-a]pyridines occurs in two steps through the formation of (2H-azirin-2-yl)pyridinium bromides followed by dehydrobrominative UV light-induced cyclization. The method can also be applied for the synthesis of imidazo[2,1-a]isoquinol ...

For the first time, a novel class of deep-blue (DB)-emitting Csₓ(NH₄)₁₋ₓPbCl₂Br (0.3 ≤ x ≤ 1) perovskite nanocrystals (PNCs) were prepared by a facile ligand-assisted one-step ball milling method. The resulted PNCs are characterized by high chlorine content (66.7%) and excellent color purity. Their photoluminescence position can be finely modulated from 434 nm to 447 nm, which extends notably beyo ...

Abstract:
... Fragmentation of plastic macro-debris into secondary microplastics [MPs] is primarily the result of their extensive oxidation under exposure to solar UV radiation. The heterogeneity in the marine zones with respect to their oxidative potential for plastics, introduces a marked zonal bias in their ability to carry out weathering and fragmentation. Comparing the oxidative environments of the beach z ...
