TL;DR: In this paper, the authors discuss the possible effects of accepting IGD as an addiction, the most important critiques regarding certain IGD criteria (i.e., preoccupation, tolerance, withdrawal, deception, and escape), and the controversies surrounding the name and content of IGD.
Abstract: Scientific interest in behavioral addictions (such as Internet gaming disorder [IGD]) has risen considerably over the last two decades. Moreover, the inclusion of IGD in Section 3 of DSM-5 will most likely stimulate such research even more. Although the inclusion of IGD appears to have been well received by most of the researchers and clinicians in the field, there are several controversies and concerns surrounding its inclusion. The present paper aims to discuss the most important of these issues: (i) the possible effects of accepting IGD as an addiction; (ii) the most important critiques regarding certain IGD criteria (i.e., preoccupation, tolerance, withdrawal, deception, and escape); and (iii) the controversies surrounding the name and content of IGD. In addition to these controversies, the paper also provides a brief overview of the recent findings in the assessment and prevalence of IGD, the etiology of the disorder, and the most important treatment methods.

TL;DR: It is concluded that for many gamers, losing track of time is a positive experience and is one of the main reasons for playing videogames.
Abstract: Playing videogames is now a major leisure pursuit, yet research in the area is comparatively sparse. Previous correlational evidence suggests that subjective time loss occurs during playing videogames. This study examined experiences of time loss among a relatively large group of gamers (n = 280). Quantitative and qualitative data were collected through an online survey. Results showed that time loss occurred irrespective of gender, age, or frequency of play, but was associated with particular structural characteristics of games such as their complexity, the presence of multi-levels, missions and/or high scores, multiplayer interactions, and plot. Results also demonstrated that time loss could have both positive and negative outcomes for players. Positive aspects of time loss included helping players to relax and temporarily escape from reality. Negative aspects included the sacrificing of other things in their lives, guilty feelings about wasted time, and social conflict. It is concluded that for many gamers, losing track of time is a positive experience and is one of the main reasons for playing videogames.

TL;DR: The electrostatic interaction, ligand exchange, and oxygen defects on LAH surfaces jointly facilitated PO4 adsorption but with varied contribution under different pH conditions, suggesting the combined contribution of two-component of La and Al may be an important direction for the next generation of commercial products for eutrophication mitigation.
Abstract: Lanthanum (La) bearing materials have been widely used to remove phosphorus (P) in water treatment. However, it remains a challenge to enhance phosphate (PO4) adsorption capacity and La usage efficiency. In this study, La was coprecipitated with aluminum (Al) to obtain a La/Al–hydroxide composite (LAH) for P adsorption. The maximum PO4 adsorption capacities of LAH (5.3% La) were 76.3 and 45.3 mg P g–1 at pH 4.0 and 8.5, which were 8.5 and 5.3 times higher than those of commercially available La-modified bentonite (Phoslock, 5.6% La), respectively. P K-edge X-ray absorption near edge structure analysis showed that PO4 was preferentially bonded with Al under weakly acid conditions (pH 4.0), while tended to associate with La under alkaline conditions (pH 8.5). La LIII-edge extended X-ray absorption fine structure analysis indicated that PO4 was bonded on La sites by forming inner sphere bidentate-binuclear complexes and oxygen defects exhibited on LAH surfaces, which could be active adsorption sites for PO4....

TL;DR: This work shows how superhydrophobic surfaces can be used to reduce protein adsorption and to promote desorption, and suggests this type of surface may be useful in environments, such as microfluidics, where protein sticking is a problem and fluid flow is present.
Abstract: Wall adsorption is a common problem in microfluidic devices, particularly when proteins are used. Here we show how superhydrophobic surfaces can be used to reduce protein adsorption and to promote desorption. Hydrophobic surfaces, both smooth and having high surface roughness of varying length scales (to generate superhydrophobicity), were incubated in protein solution. The samples were then exposed to flow shear in a device designed to simulate a microfluidic environment. Results show that a similar amount of protein adsorbed onto smooth and nanometer-scale rough surfaces, although a greater amount was found to adsorb onto superhydrophobic surfaces with micrometer scale roughness. Exposure to flow shear removed a considerably larger proportion of adsorbed protein from the superhydrophobic surfaces than from the smooth ones, with almost all of the protein being removed from some nanoscale surfaces. This type of surface may therefore be useful in environments, such as microfluidics, where protein sticking is a problem and fluid flow is present. Possible mechanisms that explain the behaviour are discussed, including decreased contact between protein and surface and greater shear stress due to interfacial slip between the superhydrophobic surface and the liquid.
