Electrocatalytic nitrogen reduction reaction (NRR) under ambient conditions provides an intriguing picture for the conversion of N 2 into NH 3 . However, electrocatalytic NRR mainly relies on metal‐based catalysts, and it remains a grand challenge in enabling effective N 2 activation on metal‐free catalysts. Here we report a defect engineering strategy to realize effective NRR performance (NH 3 yield: 8.09 μg h −1 mg −1 cat. , Faradaic efficiency: 11.59 %) on metal‐free polymeric carbon nitride (PCN) catalyst. Illustrated by density functional theory calculations, dinitrogen molecule can be chemisorbed on as‐engineered nitrogen vacancies of PCN through constructing a dinuclear end‐on bound structure for spatial electron transfer. Furthermore, the N−N bond length of adsorbed N 2 increases dramatically, which corresponds to “strong activation” system to reduce N 2 into NH 3 . This work also highlights the significance of defect engineering for improving electrocatalysts with weak N 2 adsorption and activation ability.

IOP Conference Series: Earth and Environmental science 2018年第1期102卷

作者： NP Adetya H Hadiyanto Department of Chemical Engineering Faculty of Engineering Diponegoro University Jl. Prof Soedarto SH Tembalang Semarang 50275 Indonesia Master Program of Environmental Science School of Postgraduate Studies Diponegoro University Jl. Imam Bardjo No 3-5 Semarang Indonesia

Microalgae Spirulina sp. has been identified as potential source of natural food supplement and food colorant. The high water content of microalgae (70-90%) causes an obstacle in biomass dehydration which requires large amounts of energy, eventually damaging the lipid in the microalgae. Therefore, the lipid must be extracted by using a suitable method which complies to wet biomass conditions. One of the methods is applying osmotic shock. This study was aimed to investigate the influence of osmotic agent (NaCl) concentration (10-30%) and extraction time (20-50 min) on yield of lipid and also to determine the optimal conditions in the extraction process through response surface methodology. The extraction was conducted at a temperature of 40°C under ultrasound frequency of 40 kHz. The result showed that the optimum yield lipid obtained was 6.39% in 16.98% NaCl concentration for 36 minutes 10 seconds.

Monoclonal antibody (mAb) is a very useful tool in not only medical field but also in research field. However, the current cost of its production is very high as most mAbs are produced in mammalian cell system. Escherichia coli is a good alternative but has many bottlenecks. Recently, it was demonstrated that biological active full-length Immunoglobulin G (IgG) could be produced in the reductive cytoplasm of an engineered E. coli strain called SHuffle. In this study, we investigated the effect of temperature and induction level on the production of full-length humanized anti-Her2 and chimeric anti-VEGF IgGs expressed as cyclonal. The solubility as well as the assembly of the IgG molecules was examined by western blot analysis. It was found that expression at 30 °C with 0.1 mM IPTG induction was the most suitable for trastuzumab. In contrast, the full-length expression of chimeric anti-VEGF required induction with 1 mM IPTG at 30 °C., however, 1 mM IPTG induction resulted in more full-length IgG. In conclusion, the present study indicated that E coli could be successfully used for the full-length expression of IgG by suitably modifying the expression conditions.

252nd ACS National Meeting and Exposition: Chemistry of the People, by the People, for the People

Electronic excitations in the condensed phase play a central role in several fields of modern chemical research, ranging from lightharvesting chromophores in biochemical systems to ultrafast excitations in all facets of timedomain spectroscopy. In each of these areas, the chemical system exhibits a multitude of interactions (both classical and quantum) between different chemical interfaces that give rise to the experimentallyobserved spectrum. These manybody interactions are particularly crucial in the liquid phase, as these effects are significantly more complex than in either gasphase or solidstate systems. In this talk, a new microscopic picture of solutesolvent electron dynamics and solvatochromic effects is presented, which is uncovered using a new realtime quantum dynamics approach for large solvated systems.1 In particular, we show that a complex interplay of quantum interactions underlies our observations of solutesolvent effects in a solvated donoracceptor system. Our ability to probe extremely large systems allows us to highlight the unusual manybody mechanisms that mediate solvatochromic shifts in both nonpolar and polar solvent - without recourse to empiricallyderived continuum models. Moreover, our timedomain studies of these solvated systems provide a natural approach to probe in microscopic detail the timedependent electron dynamics and couplings between the solute and solvent in emergent order. At the end of this talk, new studies (in progress) on large plasmonic systems will also be presented.

After the detection of gravitational waves from compact binary coalescences, the search for transient gravitational-wave signals with less well-defined waveforms for which matched filtering is not well suited is one of the frontiers for gravitational-wave astronomy. Broadly classified into “short” ≲1 s and “long” ≳1 s duration signals, these signals are expected from a variety of astrophysical processes, including non-axisymmetric deformations in magnetars or eccentric binary black hole coalescences. In this work, we present a search for long-duration gravitational-wave transients from Advanced LIGO and Advanced Virgo’s third observing run from April 2019 to March 2020. For this search, we use minimal assumptions for the sky location, event time, waveform morphology, and duration of the source. The search covers the range of 2–500 s in duration and a frequency band of 24–2048 Hz. We find no significant triggers within this parameter space; we report sensitivity limits on the signal strength of gravitational waves characterized by the root-sum-square amplitude hrss as a function of waveform morphology. These hrss limits improve upon the results from the second observing run by an average factor of 1.8.

This paper presents the results of a search for generic short-duration gravitational-wave transients in data from the third observing run of Advanced LIGO and Advanced Virgo. Transients with durations of milliseconds to a few seconds in the 24–4096 Hz frequency band are targeted by the search, with no assumptions made regarding the incoming signal direction, polarization, or morphology. Gravitational waves from compact binary coalescences that have been identified by other targeted analyses are detected, but no statistically significant evidence for other gravitational wave bursts is found. Sensitivities to a variety of signals are presented. These include updated upper limits on the source rate density as a function of the characteristic frequency of the signal, which are roughly an order of magnitude better than previous upper limits. This search is sensitive to sources radiating as little as ∼10−10 M⊙c2 in gravitational waves at ∼70 Hz from a distance of 10 kpc, with 50% detection efficiency at a false alarm rate of one per century. The sensitivity of this search to two plausible astrophysical sources is estimated: neutron star f modes, which may be excited by pulsar glitches, as well as selected core-collapse supernova models.

IOP Conference Series: Earth and Environmental science 2018年第1期105卷

作者： Yogi Wibisono Budhi Dhinny Dwi Putri Afifa Husna Hans Kristian Irawan Manabu Miyamoto Shigeyuki Uemiya Chemical Engineering Study Program Institut Teknologi Bandung Jl. Ganesha 10 Bandung Indonesia Department of Materials Science and Technology Gifu University 1-1 Yanagido Gifu 501-1193 Japan

Hydrogen has been considered as promising energy carrier that can be produced from renewable resources, such as biomass through gasification. This process results in producer gas containing CO, CO2, H2, N2, and CH4. The conventional enhancement of hydrogen is typically conducted using several unit operations such as water gas shift reactor (WGSR) and separation unit such as Pressure Swing Adsorption (PSA). Process intensification offers a new method to integrate both WGSR and separation unit into single membrane reactor. This research aimed to investigate the influence of dynamic operation on membrane reactor performance. The steady state fixed bed reactor and membrane reactor were used as base case to judge the performance of dynamic membrane reactor. The water gas shift reaction over Fe2O3/Cr2O3/CuO was carried out at 350°C and 1 atm by varying the feed composition and gas residence time. The feed composition ratio of H2O/CO consisted of 2 and 3 on mole basis, while the gas residence times were 1.2 s and 2.3 s. The membrane reactor consists of shell and tube sides made of Pd/Al2O3 material with technical specification of 10 mm inner diameter, 20 μm Pd thickness supported by alumina, and 10 cm reactor length. The compositions of the feed gas and products were measured using gas analysers such CO gas detector (Bacharach PCA® 3) and H2 gas detector (Cosmos XP-3140). The dynamic operation was performed following the square wave perturbation of the feed gas at switching time of 15 s. The experiment results showed that increasing the feed composition ratio and gas residence time increased the conversion of CO and hydrogen production in the fixed bed reactor and membrane reactor. Higher production of hydrogen also improved the recovery of hydrogen in membrane reactor. The use of membrane reactor increased significantly the conversion of CO when compared to fixed bed reactor. Moreover, the dynamic membrane reactor would give much better performance in term of CO conversio

Faunus ater is a favoritemollusca that is often found on the Bale River. Local people use these snails as food for consumption along with their main food. Bale River itself is located adjacent to the cement factory, used water washing machines distributed to the river is feared to support the presence of lead (Pb) and zinc (Zn) metals in the river. This study aims to analyze the relationship of Pb and Zn content in sediments to the content of Pb and Zn in Faunus ater. Data collection was carried out in Februari until April 2018. The relationship between Pb and Zn content in sediments with Pb and Zn content in the body of Faunus ater was analyzed by correlation analysis. The results of the data analysis showed that the metal content of Pb and Zn in sediment and Faunus aterwere found to vary. The highest Pb content in sediment was found at station 2 in March, amounting to 32.87 mg / kg. while the highest Zn content was found at station 1 in March amounting to 84 mg / kg. The relationship of heavy metals Pb and Zn in sediments to the content of Pb and Zn in the body of Faunus ater showed a negative correlation. The conclusion of this study is that there is no correlation between the content of Pb and Zn heavy metals in sediments on the content of lead Pb and Zn in the body of Faunus ater at the Bale Lhoknga River in Aceh Besar District.
