Effect of Laser-Exposed Volume and Irradiation Position on Nonphotochemical Laser-Induced Nucleation of Potassium Chloride Solutions.

Herein, we study the influences of the laser-exposed volume and the irradiation position on the nonphotochemical laser-induced nucleation (NPLIN) of supersaturated potassium chloride solutions in water. The effect of the exposed volume on the NPLIN probability was studied by exposing distinct milliliter-scale volumes of aqueous potassium chloride solutions stored in vials at two different supersaturations (1.034 and 1.

Design and Validation of a Droplet-based Microfluidic System To Study Non-Photochemical Laser-Induced Nucleation of Potassium Chloride Solutions.

Non-photochemical laser-induced nucleation (NPLIN) has emerged as a promising primary nucleation control technique offering spatiotemporal control over crystallization with potential for polymorph control. So far, NPLIN was mostly investigated in milliliter vials, through laborious manual counting of the crystallized vials by visual inspection. Microfluidics represents an alternative to acquiring automated and statistically reliable data.

Mechanism of enhanced enzymatic hydrolysis performance by ethanol assisted deep eutectic solvent pretreatment- from the perspective of lignin.

Valorization of lignocellulose has received a lot of attention due to the abundance of lignocellulosics. It was showed that synergistic carbohydrate conversion and delignification could be achieved via ethanol assisted DES (choline chloride/lactic acid) pretreatment. To explore the reaction mechanism of lignin in the DES, milled wood lignin obtained from Broussonetia papyrifera was subjected to pretreatment at critical temperatures.

Pursuing Green and Efficient Agriculture from Molecular Assembly: A Review of Solid-State Forms on Agrochemicals.

Achieving rapid global agricultural development while maintaining ecological harmony is a major challenge of the new millennium. Meeting this challenge requires the development of efficient and environmentally friendly agrochemicals, including pesticides and fertilizers. Molecular assembly, as a promising strategy, has garnered significant attention in recent years for the development of advanced solid-state forms of agrochemicals.

Effects of various parameters on solution-mediated phase transformation of calcium d-gluconate: an approach to obtain pure metastable monohydrate.

The high risk of solution-mediated phase transformation (SMPT) from the metastable monohydrate to stable Form I makes it difficult to produce pure metastable monohydrate of calcium d-gluconate. In this work, we explored the effect of various operating parameters on the SMPT of calcium d-gluconate in water and proposed an effective approach to obtain the desired monohydrate. First, the two forms of calcium d-gluconate were characterized and compared using powder X-ray diffraction (PXRD), thermal analysis, and Raman spectroscopy.

Dental erosion caused by glucocorticoid therapy in a patient with optic neuritis: a case report.

Dental erosion is characterized by progressively destroyed teeth, which has no relation to bacteria but to chemicals. Some internal factors, such as gastroesophageal reflux induced by bulimia, anorexia, gastrointestinal diseases, or drugs, and external factors, such as diet, drugs, and occupational acid exposure, are considered promotive factors for this disease. This article presents a patient suffering from severe dental erosion in the whole dentition, especially in the maxillary teeth, due to gastroesophageal reflux induced by glucocorticoid therapy for optic neuritis.

Effective fractionation of lignocellulose components and lignin valorization by combination of deep eutectic solvent with ethanol.

A combination of deep eutectic solvent with ethanol was developed for pretreatment of to effectively extract lignin and promote the subsequent enzymatic hydrolysis. In order to further explore the optimal conditions for enzymatic hydrolysis, a central composite design method was applied. The correlation between each factor and glucose yield was obtained, and the optimal conditions was 160°C, 60 min, the ratio of DES to E was 1/1 (mol/mol).

Exploring the Effects of the Interaction of Carbon and MoS Catalyst on CO Hydrogenation to Methanol.

Hydrogenation of CO to form methanol utilizing green hydrogen is a promising route to realizing carbon neutrality. However, the development of catalyst with high activity and selectivity to methanol from the CO hydrogenation is still a challenge due to the chemical inertness of CO and its characteristics of multi-path conversion. Herein, a series of highly active carbon-confining molybdenum sulfide (MoS@C) catalysts were prepared by the in-situ pyrolysis method.

Zoledronate promotes bone formation by blocking osteocyte-osteoblast communication during bone defect healing.

Nitrogen-containing bisphosphonates (N-BPs) are potent antiresorptive drugs and their actions on osteoclasts have been studied extensively. Recent studies have suggested that N-BPs also target bone-forming cells. However, the precise mechanism of N-BPs in osteoblasts is paradoxical, and the specific role of osteocytes is worthy of in-depth study.

[Maxillary first molar with two distobuccal root canals: a case report].

The root and canal anatomy of maxillary first molar is very complicated. The incidence of having two canals in the mesiobuccal root of maxillary first molar is higher than that in its distobuccal root. This article described a maxillary first molar with five root canals, including two canals in mesiobuccal and distobuccal roots.

Isolation and phenotypic characterization of side population cells in oral squamous cell carcinoma.

A subset of cancer stem cells termed 'side population' (SP) cells has been identified in several types of solid tumor and is known to be responsible for the failure of chemotherapy and for cancer relapse. In the present study, the oral squamous cell carcinoma (OSCC) cell line SCC‑55 was used for analysis of the SP cells based on Hoechst 33342 exclusion, via the ATP‑binding cassette (ABC) transporter, with and without verapamil using fluorescence activated cell sorting. The results demonstrated that the presence of SP cells in the SCC‑55 cell line was 2.
