Platinum/nitrogen-co-doped TiO as photocatalyst and light-free catalytic adsorbent for gaseous formaldehyde.

Platinum and nitrogen co-doped titanium dioxide (Pt/N-TiO, with 1 wt% Pt and an N/Ti molar ratio of 1) has been synthesized. This Pt/N co-doping strategy creates Schottky junctions, reduces the bandgap energy (3.25 to 2.

The smoking of heat-not-burn (HNB) cigarette products and its effects on indoor air quality.

In this research, the concentration levels of volatile organic compounds (VOCs) are monitored in a designated smoking booth using heat-not-burn (HNB) cigarettes (in reference to 1R6F cigarette) with controlled variables of number of cigarettes smoked (1, 3, and 6 cigarettes), booth ventilation (closed vs. open), and time after the release of cigarette smoke (T = 0, T = 5, T = 10, and T = 20 min)). The total VOC concentration (TVOC) released from an HNB cigarette is compared as a collective group (TV) and as three individual subgroups (TV: TV for 14 standardized VOCs (G), TV for 17 reference VOCs (G), and TV for 10 carbonyl compounds (CCs: G).

Mechanism, Performance, and Application of g-CN-Coupled TiO as an S-Scheme Heterojunction Photocatalyst for the Abatement of Gaseous Benzene.

In this research, S-scheme heterojunction photocatalysts are prepared through the hybridization of nitrogen-rich g-CN with TiO (coded as TCN-(): as the weight ratio of TiO:g-CN). The photocatalytic potential of TCN-() is evaluated against benzene (1-5 ppm) across varying humidity levels using a dynamic flow packed-bed photocatalytic reactor. Among the prepared composites, TCN-(10) exhibits the highest synergy between g-CN and TiO at "" ratio of 10%, showing superior best benzene degradation performance (e.

The extent of harmful volatile organic compounds released when smoking after breaking the flavor capsules of heat-not-burn (HNB) cigarette products.

A number of flavored capsule heat-not-burn (FC-HNB) tobacco products such as IQOS, Lil, and Glo have been introduced as a new generation of cigarettes. As they can release various types of volatile organic compounds (VOCs), it is important to assess the harmfulness associated with their use. Thus, the composition of VOCs in HNB cigarette vapor was evaluated to investigate the interactive roles of key variables controlling the relationships between VOC composition and capsule breaking, particularly the compositional changes induced by capsule breaking and release of flavor from FC-HNB cigarettes relative to regular products.

Volatile organic compounds released in the mainstream smoke of flavor capsule cigarettes.

In this study, the composition of mainstream smoke was investigated with an emphasis on a list of volatile organic compounds (VOCs: e.g., isoprene, acrylonitrile, methyl ethyl ketone, benzene, toluene, m-xylene and styrene) using the two types of flavor capsule cigarettes (FCCs, here coded as F1 and F2) in reference to one commercial, non-flavored (NF) and 3R4F cigarette.

An efficient strategy for the enhancement of adsorptivity of microporous carbons against gaseous formaldehyde: Surface modification with aminosilane adducts.

In an effort to develop a cost-effective mitigation tool for volatile organic compounds, particularly formaldehyde (FA), microporous activated carbon (AC) was modified into three different forms of AC-1, AC-2, and AC-3 using a raw commercial AC product (AC-0). First, AC-1 and AC-2 were produced by the modification of AC-0 with N/S heteroatoms using identical mixture of dicyandiamide and thiourea precursors through either solvothermal (AC-1) or microwave-assisted calcination (AC-2) synthesis. Second, aminosilane-functionalized AC (AC-3) was prepared solvothermally using N-[3-(Trimethoxysilyl)propyl]ethylenediamine reagent.

Electricity production and phosphorous recovery as struvite from synthetic wastewater using magnesium-air fuel cell electrocoagulation.

This research was based on the investigation of a major principle, regarding the effects of NaCl and KHPO concentrations on struvite recovery, with electricity production using magnesium-air fuel cell electrocoagulation, in accordance with the concentration of phosphorous and chloride. The weight ratio of N:P in the synthetic wastewater was in the range of 1.2-21.

Long-Term Blood Pressure Control Effect of Celiac Plexus Block with Botulinum Toxin.

Celiac plexus block (CPB) is one of the main treatment options for patients resistant to conventional antihypertensive drugs. We present a case of resistant hypertension (RHTN) that was treated with CPB using botulinum toxin. An 18-year-old male patient with RHTN, who suffered from persistent hypertension even after combination therapy and a renal denervation procedure, was referred to our pain center for CPB.
