Thermal Lithiated-TiO<sub>2</sub>: A Robust and Electron-Conducting Protection Layer for Li–Si Alloy Anode
Developing new electrode
materials with high capacity and stability
is an urgent demand in electric vehicle applications. Li<sub><i>x</i></sub>Si alloy, as a promising high-capacity and Li-containing
anode candidate, has attracted much attention. However, the alloy
anode suffers severely from intrinsic high chemical reactivity and
poor cycling stability in battery fabrication and operation. Here,
we have developed a facile coating-then-lithiation approach to prepare
lithiated-TiO<sub>2</sub> protected Li<sub><i>x</i></sub>Si nanoparticles (Li<sub><i>x</i></sub>Si–Li<sub>2</sub>O/Ti<sub><i>y</i></sub>O<sub><i>z</i></sub> NPs) as an attractive anode material. The robust lithiated-TiO<sub>2</sub> protection matrix not only provides fast electron transport
pathways to efficiently improve the electrical conductivity between
Li<sub><i>x</i></sub>Si/Si NPs, but also spatially limits
the direct solid electrolyte interphase formation on Li<sub><i>x</i></sub>Si/Si cores during cycling. More importantly, this
dense coating layer protects most inner Li<sub><i>x</i></sub>Si alloys from ambient corrosion, leading to high dry-air stability.
As a result, the resulting Li<sub><i>x</i></sub>Si–Li<sub>2</sub>O/Ti<sub><i>y</i></sub>O<sub><i>z</i></sub> anode achieves greatly enhanced cycling and chemical stability in
half-cells. It maintains capacity of about 1300 mAh g<sup>–1</sup> after prolonged 500 cycles at a high current rate of C/2, with 77%
capacity retention. In addition, it exhibits excellent dry-air stability,
with around 87% capacity retained after exposure to dry air (10% relative
humidity) for 30 days
DataSheet2_Cyclohexane removal and UV post-control of bioaerosols in a combination of UV pretreatment and biotrickling filtration.DOCX
Biofiltration of hydrophobic and recalcitrant volatile organic compounds faces challenges, and the bioaerosols sourced from the biofiltration might cause secondary pollution. In this study, the combination of ultraviolet photodegradation and biotrickling filtration (UV-BTF) was designed to treat gaseous cyclohexane, and UV post-treatment (post-UV) was further utilized for the bioaerosol emissions management. Results showed that the combined UV-BTF permitted faster biofilm formation and had better removal efficiencies (REs) than the single biotrickling filter (BTF). The maximum elimination capacity (EC) of UV-BTF and single BTF was 4.4 and 1.32 g m−3 h−1, respectively. Carbon balance for the bioreactor showed that both BTF and UV-BTF could convert more than 50% of the initial cyclohexane into microbial biomass. High-throughput sequencing analysis showed that UV-BTF had a richer and more diverse microbial community compared with the single one. The post-UV had a good inactivation effect on the bioaerosols. Not solely the concentrations additionally the particle sizes of the bioaerosols from the post-UV became lower and smaller than those from the single BTF. Microbial analysis showed that UV had a greater impact on the species and quantity of both bacteria and fungi, but mainly on the number of bacteria. Such results suggested that UV could be used as the pretreatment for the enhancement of hydrophobic and recalcitrant VOCs removal in the subsequent biopurification, and also as the post-treatment for the inactivation of some harmful bioaerosols.</p
Sulfite as a Green Co-milling Agent for Mechanochemical Destruction of Polychlorinated Aromatics: Working Mechanism and Structural Dependence
Mechanochemical destruction of obsolete halogenated persistent
organic chemicals (especially polychlorinated aromatics) has been
documented as a safe non-combustion technology, but the smooth implementation
of such a system still calls for an appropriate and sustainable co-milling
agent. As an example, we show that Na2SO3 as
a co-milling agent not only achieves faster degradation rate for hexachlorobenzene
(HCB) than calcium oxide (1.4-fold) and reduced iron powders (2.9-fold)
with equal mass but also enables high dechlorination ratio (97.4%)
after 4 h of milling in a planetary mill. With the input of mechanical
energy, the mechanistic study suggests that sulfite salts suffer partial
melt to generate SO32– species on fresh
surfaces, which attack HCB molecules via the one-electron-transfer
mechanism. Detection on intermediates and characterization on milled
samples demonstrate that HCB undergoes dechlorination, polymerization,
and hydrogenation and finally converts to amorphous and graphitic
carbons. Correlation analysis indicates that the degradation reactivity
of a specific polychlorinated aromatic compound in such a system is
strongly dependent on its molecular structure (e.g., substituent groups
and degree of chlorination). This work provides a new insight for
utilizing sulfite for green disposal of halogenated wastes

Laws that are made to be broken
Criminal laws are created to achieve various ends. These include (i) reducing the incidence of wrongdoing, and (ii) holding wrongdoers responsible for their wrongs. Some criminal laws are created to further the first of these ends by means of compliance. The second end is to be furthered only if, regrettably, some fail to comply. These criminal laws are made to be followed. Other criminal laws are not created with compliance in mind. Conviction, in these cases, is no regrettable fallback. It is the primary means by which the law is to contribute to ends (i) and (ii). Laws of this second kind are made to be broken. My concern in this paper is with the creation of such laws. Section I sharpens the contrast drawn above, and considers some arguments for enacting laws that are made to be broken. The following sections develop an argument against. Section II introduces what I call the ‘identification principle.’ It argues that the principle is an implication of the ideal of the rule of law, and that it binds state officials who make, apply, and enforce criminal laws. Section III argues that, when laws are made to be broken, the identification principle is violated. Section IV concludes
