#1
Yoshie Ishikawa, Naoto Koshizaki
Pulsed laser melting in liquid (PLML) is a technique to fabricate submicrometer crystalline spherical particles of various materials by laser irradiation of suspended raw particles with random shapes. To fully exploit the unique features of PLML-fabricated particles (crystalline and spherical) in practice, a mass-production PLML technique is required. To this end, the present study develops a new slit nozzle that guides the suspension film flow into a non-droplet continuous stream with a low flow rate. These two incompatible flow properties (continuity and slowness) are difficult to be realized for a liquid jet to free space...

Ye Tian, Xiaoying Gao, Wei Hong, Miao Du, Pengju Pan, Jing Zhi Sun, Zi Liang Wu, Qiang Zheng
In a previous work (ACS Appl. Mater. Interfaces 2017, 9, 34349-34355), a facile approach was reported to prepare thin hydrogel films based on the Marangoni effect. After dripping onto a water surface, a drop of ethanol solution of poly(stearyl acrylate-co-acrylic acid) (P(SA-co-AAc)) spread quickly to form a thin film. The solvent exchange from ethanol to water led to the gelation of polymer solution which turned into a hydrogel film. Here we investigate the scenario and seek for the governing kinetics of the Marangoni-effect-assisted preparation of hydrogel films...

The aim of this work was to analyse the effect of different osmotic dehydration (OD) processes (sucrose, trehalose, glucose, lactose) as a pre-treatment for grape before exposure to freezing. The osmotic treatment had less effect on blueberry moisture content among different sugars. Impregnation with sugars decreases the freezing time of grapes, compared to untreated grapes. Trehalose and lactose had a remarkable effect on shortening the time for grapes to pass the zone of maximum crystallisation of ice. It was concluded that drip loss and electrolyte permeability of cell membranes decreased and the soluble solids content increased after osmotic dehydration treatment...

While many techniques are known to music creators, the technique of repetition is one of the most commonly deployed. The mechanism by which repetition is effective as a music-making tool, however, is unknown. Building on the speech-to-song illusion (Deutsch, Henthorn, & Lapidis in Journal of the Acoustical Society of America, 129(4), 2245-2252, 2011), we explore a phenomenon in which perception of musical attributes are elicited from repeated, or "looped," auditory material usually perceived as nonmusical such as speech and environmental sounds...

Xuesaitong (XST) is mainly used to treat cardiovascular and cerebrovascular diseases, sometimes causing cutaneous adverse drug reactions (cADRs) with unknown mechanisms of pathogenicity or risk factors. We aimed to verify whether human leukocyte antigen (HLA) alleles are associated with XST-related cADRs in Han Chinese population. We carried out an association study including 12 subjects with XST-induced cADRs, 283 controls, and 28 XST-tolerant subjects. Five out of 12 patients with XST-induced cADRs carried HLA-C*12:02, and all of them received XST via intravenous drip...

The effect of season, localization, filleting regime and storage on water-holding properties of Atlantic salmon ( Salmo salar L.) was investigated. Salmon was sampled at two different slaughter facilities (in the north and south of Norway) in autumn and spring and divided in pre- and post-rigor groups, which were sampled before and after filleting. This gave a total of 16 groups that were analyzed for water-holding capacity (WHC), water content and pH. In addition, a storage trial was performed to assess the effect of all the design variables on drip loss and the composition of the drip loss during up to 18 days of storage...

Hybrid organic-inorganic perovskite nanowires have received considerable attention for applications in optoelectronic fields; however, practical implementation of perovskite nanowires into optoelectronic devices is often hindered by low product yields, scaled-up synthesis, or overall lack of synthetic control. Herein, we report novel insights into large-scale freestanding lead halide perovskite nanowires using a series of solvent effects. A facile pathway for converting layered raw materials to nanowires with high conversion yields can facilitate the large-scale applications of nanowires, which could help us understand the unique aspects of the formation chemistry of the materials...

The formation of droplets is ubiquitous in many natural and industrial processes and has reached an unprecedented level of control with the emergence of milli- and microfluidics. Although important insight into the mechanisms of droplet formation has been gained over the past decades, a sound understanding of the physics underlying this phenomenon and the effect of the fluid's flow and wetting properties on the droplet size and production rate is still missing, especially for the widely applied method of step emulsification...

A multilayered water-skin model is used to experimentally verify a new sensing method for determining the skin penetration depth of radiation with 0.1-0.9 terahertz (THz) frequencies. A water overlayer is dripped on a skin sample to form a multilayered structure for dynamically measuring the reflected THz-wave amplitude during water desorption. Skin penetration depths can be successfully derived by using the multilayered water-skin model and by considering the measured reflectivity, water dielectric constants, and effective thicknesses of the water overlayer on the skin sample...

Irrigation is the main source of soil water in greenhouse. There is a lack of understanding on the effects of drip irrigation under the plastic film on the distribution characteristics of soil nutrients, enzyme activity and glomalin-related soil protein (GRSP) in soil aggregates. The effects of different irrigation low limits (20 kPa, D20 ; 30 kPa, D30 ; 40 kPa, D40 ) on soil organic carbon (SOC), total nitrogen (TN), total phosphorus (TP), urease activity, invertase activity and GRSP in soil aggregates were investigated under the greenhouse with the continuously six years' irrigation...

The setting up of innovative irrigation water management might contribute to the mitigation of negative issues related to climate change. Our hypothesis was that globe artichoke irrigated with a traditionally drip system could be converted to an innovative water management system based on precision irrigation techniques and on evaporative cooling application in order to improve crop physiological status with positive impacts on earliness, total heads yield and water saving. Over two experiments carried out at plot- and field-scale, two irrigation management systems, differing in type and application time, were compared: (i) conventional, and (ii) canopy-cooling...

We report a new immersed alternating current (AC) electrospray droplet generation method that can generate monodispersed water-in-oil droplets, with diameters ranging from 5  μ m to 150  μ m, in a stationary oil phase. This method offers high through-put, easy size tuning, and droplets with a viscous aqueous phase at high ionic strengths (raw physiological samples). Yet, it does not require coordinated flows of the dispersed/continuous phases or even a microfluidic chip. The design relies on a small constant back pressure (less than 0...

This study aimed to investigate the effects of creatine monohydrate (CMH) and guanidinoacetic acid (GAA) supplementation on the growth performance, meat quality, and creatine metabolism of finishing pigs. The pigs were randomly allocated to three treatment groups: the control group, CMH group, and GAA group. In comparison to the control group, CMH treatment increased average daily feed intake and GAA treatment increased average daily feed intake and average daily gain of pigs. In addition, CMH and GAA treatment increased pH45 min , myofibrillar protein solubility, and calpain 1 mRNA expression level and decreased the drip loss and shear force value in longissimus dorsi or semitendinosus muscle...

Sodium-glucose cotransporter 2 (SGLT-2) inhibitors are a class of medications used for glycemic control in type II diabetes mellitus. Their mechanism of action involves preventing resorption of glucose at the proximal kidney, thereby promoting glucosuria and weight loss. However, they have also been found to be associated with euglycemic diabetic ketoacidosis (euDKA). This case describes a 25-year-old male with a history of type II diabetes on metformin, sitagliptin, and dapagliflozin who was admitted with his third episode of pancreatitis secondary to hypertriglyceridemia...

In this manuscript, flame-retardant and smoke-suppressant flexible polyurethane foams (FPUFs) were designed and synthesized based on novel liquid phosphorus-containing polyol named as PDEO and expandable graphite (EG). The reactive PDEO can be chemically added into the chain of FPUF, while expandable graphite was blended into the matrix of foam through foaming process. Benefitting from the incorporation of reactive PDEO with a long chain, the resultant FPUF containing EG exhibited considerable mechanical properties...
