AbstractThe ability to achieve dual‐mode thermal regulation for switchable heating and cooling on a single platform has thus far been challenged by the availability of suitable materials. The materials need to possess both high solar reflectance and high transmittance, necessitating large and small thicknesses in the same coating layer, respectively (i.e., the thickness constraint). Herein, for the first time, a single‐layer coating made in a facile one‐step process is reported, which exhibits rapid switch between high solar reflection (≈96.6%) and high solar transmission (≈86.6%). In the dry state, high solar reflectance and infrared (IR) emittance (>96% from 8 to 13 µm) enable passive radiative cooling, resulting in all‐day near/sub‐ambient temperatures in the demanding weather conditions of the tropical climate. Upon wetting, high transparency in the broadband range (0.3–2.5 µm) allows solar heating, leading to switchable thermal regulation. Such unprecedented performances are achieved through a unique hierarchical porous structure comprising of vertically aligned microscale pores in nanoscale pore matrix. This structure breaks the thickness constraint and broadens its applicability, in particular for seasonal areas with large temperature variation throughout the day.

AbstractTetrahedral framework nucleic acids (tFNAs) have attracted extensive attention as drug nanocarriers because of their excellent cellular uptake. However, for oligonucleotide cargos, tFNA mainly acts as a static delivery platform generated via sticky‐ended ligation. Here, inspired by the original stable space inside the tetrahedral scaffold, a dynamic lysosome‐activated tFNA nanobox is fabricated for completely encapsulating a short interfering RNA (siRNA) of interest. The closed tetrahedral structure endows cargo siRNA with greater resistance against RNase and serum and enables solid integration with the vehicle during delivery. Moreover, the pH‐responsive switch of nanobox allows the controlled release of siRNA upon entry into lysosomes at cell culture temperature. Based on protective loading and active unloading, an excellent silencing effect on the target tumor necrosis factor alpha (TNFα) gene is achieved in in vitro and in vivo experiments. Conclusively, the nanobox offers a dynamic pH‐sensitive confinement delivery system for siRNA and can be an extendable strategy for other small RNA.

AbstractCarbon‐supported Pt‐based electrocatalysts have been widely investigated for diverse electrochemical energy storage and conversion applications. Vulcan XC72R (VC) supported Pt(20 wt%) nanoparticles (NPs) (denoted as Pt(20 wt%)NPs/VC produced by Johnson Matthey (JM)) is the most commonly‐used catalyst and is thus widely considered to be the state‐of‐the‐art electrocatalyst. Although Pt(20 wt%)NPs/VC(JM) has demonstrated very good electrocatalytic performance in these applications, further improvement in its electrocatalytic activity and electrochemical stability is still highly desired. In this study, an innovative strategy, involving graphitic carbon nitride (g‐CN) coating of the electrocatalyst, is shown to improve the performance. Although other researchers have attempted modifying the support and components during the process of making an electrocatalyst, the authors report, for the first time, the nitriding of an existing catalyst, that is, post‐modification of the electrocatalyst. Due to the unique features of g‐CN coating, which include high chemical stability, good oxygen adsorption and improved ionomer distribution in the catalyst layer, the g‐CN‐coated Pt(20wt%)NPs/VC(JM) electrocatalyst (g‐CN content: 0.61 wt%) has demonstrated both improved polarization performance and electrochemical stability. This simple but very effective strategy is believed to open a new avenue for improvement of electrocatalytic performance for a range of diverse commercially‐available electrocatalysts used in proton exchange membrane fuel cells.

AbstractDeveloping high performance, low‐cost solid‐state light emitters in the telecom wavelength bandwidth is of paramount importance for infrared light‐based communications. Colloidal quantum dot (CQD) based light emitting diodes (LEDs) have shown tremendous advances in recent times through improvement in synthesis chemistry, surface property, and device structures. Despite the tremendous advancements of CQD based LEDs in the visible range with efficiency reaching theoretical limits, their short‐wave infrared (SWIR) counterparts mainly based on lead chalcogenide CQDs, have shown lower performance (≈8%). Here the authors report on highly efficient SWIR CQD LEDs with a recorded EQE of 11.8% enabled by the use of a binary CQD matrix comprising QD populations of different bandgaps at the emission wavelength of 1550 nm. By further optimizing the optical out‐coupling via the use of a hemispherical lens to reduce optical waveguide loss, the EQE of the LED increased to 18.6%. The CQD LED has an electrical bandwidth of 2 MHz, which motivated them to demonstrate its use in the first SWIR free‐space optical transmission link based entirely on CQD technology (photodetector and light emitter) opening a new window of applications for CQD optoelectronics.

AbstractThe Southern Great Plains (SGP) region of the United States is widely known for its dryland dual‐purpose winter wheat (Triticum aestivum L.) cropping systems—integrated systems that provide both livestock grazing and grain production. Few of these systems are organic, however, and no relevant research had been conducted on this topic. A large‐scale (41 ha) systems research study was conducted for 3 yr (2018–2021) to compare a transitional organic dual‐purpose wheat system with a conventional one, with system management components customized to the ecological region. Organic wheat yield was 20% lower than conventional in the first season of organic transition, but there was no yield difference by the third year. The yield improvement in the organic system may be attributed to N fixation by a legume‐based cash crop the previous winter season, exogenous nutrients from application of composted manure, and appropriate wheat cultivar selection. Because of limited moisture, relying on annual establishment of summer cover crops to fix N and deliver other ecosystem services in the organic system was not feasible in most years. Grain protein concentration (GPC) of the transitional organic wheat ranged from 91 to 103 g kg−1, below the 120 g kg−1 threshold for a food market organic price premium. More intensive N management, including in‐season application of a more available form of N that is organic approved, could be an effective strategy to increase GPC. This proof‐of‐concept study shows that organic dual‐purpose wheat systems can be a viable enterprise in the SGP, though additional research is needed to address challenges identified herein.

AbstractOrganic–inorganic nanocomposites have attracted great interest due to the remarkable improvement in mechanical properties when compared to neat polymers. The use of a low‐cost nanofiller added to good properties becomes attractive to the industry. Attapulgite (ATP) is a very interesting nanofiller alternative, especially when used with polyolefins, as in the case of high‐density polyethylene (HDPE). However, this system is not simple, as HDPE is a nonpolar polyolefin that can cause low dispersion of ATP. One way to increase the interaction between these phases is the surface modification of ATP. In this work, the surface of ATP was modified using trimethylamine hydrochloride. HDPE/ATP nanocomposites with 1 and 5 wt% of raw ATP (ATPr) or organophilic ATP (ATPo) were prepared by extrusion. The effectiveness of the organophilization process of ATP was evaluated by X‐ray diffraction, mechanical properties (Shore D hardness and tensile test), and thermal properties (thermogravimetric analysis and differential scanning calorimetry), contact angle, and scanning electron microscopy. In the HDPE/ATPo nanocomposites, it was possible to observe an improvement in mechanical and thermal properties when compared to HDPE/ATPr nanocomposites. The organophilization of ATP promoted a greater interaction between the phases, contributing to a better dispersion of ATP in the HDPE matrix.

AbstractThe objective of the current research is to propose new polymer composites with optimal acoustic properties. To do so, the ethylene‐vinyl acetate foam is employed as the based polymer and the nano silica, nano clay and graphene nanoplatelets are used as extra ingredients. The appropriate amounts of the blowing agent and nano materials are determined using the Taguchi design technique. Using the L9(34) Taguchi array, different foams are manufactured and their specifications are determined experimentally. Most importantly, the sound absorption and transmission loss of the foams are measured and utilized to specify their noise reduction coefficient (NRC) as well as their average transmission loss (ATL). To maximize the NRC and ATL, optimal formulations are derived based on the Taguchi method. Then the optimal foams are manufactured to characterize their acoustic properties. Experimentations show that both NRC and ATL are respectively improved by 9.76% and 7.98% compared to the best NRC and ATL record of the samples of the Taguchi table. Some new samples with at most one nano material are also produced to study the synergistic effects of the nano materials. Measurements of the acoustic properties of these foams revealed that the combination of the nano materials offers superior acoustic properties.

AbstractElectrospinning is an efficient technique to fabricate nanofibers of controlled diameter and uniform morphology. Herein, we report a low‐cost and high‐yield route to fabricate PAN/DAC composite nanofibers and its use for vapor sensing of 2,4‐Dinitrotoluene (DNT) and 2,4,6‐Trinitrotoluene (TNT) with a detection level in the range of parts‐per‐billion. Furthermore, the sensing ability and photo‐induced electron transfer mechanism of DAC towards DNT and TNT in the solution phase were also investigated in detail via absorption, steady‐state, and time‐resolved fluorescence spectroscopy and further supported by density function theory (DFT). The calculated Stern‐Volmer quenching constants, 810 M−1 (DNT) and 1170 M−1 (TNT), revealed that DAC is not much sensitive in solution‐phase because of the self‐condensation phenomenon of DAC molecules. This concern was addressed by the development of a fluorescent nanofiber probe constituting π‐electron‐rich carbazole (CZ) derivatives, namely 3,6‐Diaminocarbazole (DAC) as a fluorescent material and polyacrylonitrile (PAN) as a support polymatrix. This fluorophore‐doped nanofiber matrix was fabricated at a relatively lower wt% ratio (PAN:DAC::10:6), obtaining an average diameter of 857 nm and exhibited promising features in the vapor detection of DNT and TNT such as fast response time, excellent sensitivity and selectivity. Reduction of self‐condensation caused DAC molecules' fluorescence self‐quenching by simply employing the electrospinning technique to cast PAN/DAC nanofibrous film. This work promises a new aspect of sensitivity enhancement of carbazole molecular unit by amine modification and further incorporation into the polymer matrix. This nanofiber‐based sensor can lead to the design and development of highly efficient and field‐deployable vapor sensors for the detection of nitroaromatic compounds, with application in both explosive sensing and environment pollution.

Published: May 2022

AbstractIn this study, we report for the first time about using glyoxal‐based electrolytes in combination with a Fe2O3@C‐based conversion type anode for application in lithium‐ion batteries (LIBs). We show that at room temperature (RT) the use of these alternative electrolytes is possible, but it is not more advantageous than that of the conventional LP30. At 60 °C, on the other hand, utilizing a glyoxal‐based electrolyte appears very promising since the Fe2O3@C‐based electrode, cycled in combination with 1 M LiTFSI in TEG:PC+2 % VC, displays a high specific capacity (800 mAh g−1) and a high stability over 500 cycles. X‐ray photoelectron spectroscopy (XPS) measurements indicate that these high performances are possible thanks to the generation of a thermally stable and thick SEI, which is particularly favorable for maintaining a highly reversible conversion reaction.

Published: May 2022

AbstractMarginal agricultural land (MAL) has received much attention in research and policy formation as a potential resource for cultivating biomass for energy and biobased products. However, it is still unclear whether biomass from MAL meets the requirements of social sustainability. This study develops a conceptual linkage between value‐chain analysis and social life‐cycle analysis (S‐LCA), and assesses both positive impacts (handprints) and negative impacts (footprints). A participatory approach including interviews and surveys was used to understand views and perceptions of the relevant stakeholders. A systemic strategy was applied to analyze value‐chain activities, understand challenges, and identify competitive advantages and disadvantages. For S‐LCA, the variety of impacts and indicators was met through a literature review and a consistent scoring system. The cultivation of perennial crops on MAL tends to cause skepticism among stakeholders, who are concerned about long‐term commitment and biodiversity risks. Annual crops, on the other hand, are perceived by all stakeholder categories as very promising opportunities across all impact categories and indicators. They can facilitate income diversification and offer smart sustainable cropping options through crop rotation, agroforestry, etc. Most of the technological pathways examined are highly innovative, have a low technological readiness level, and are still at the early market development stage. As such they are ranked by stakeholders as medium opportunities for short‐term implementation. In contrast, pyrolysis to industrial heat, ethanol from switchgrass, insulation material from hemp, and biogas/biomethane from sorghum are considered opportunities with good chances of being implemented in the short term. © 2022 The Authors.

Bio‐economy for sustainable growth in developing countries: The case of oil palm in Malaysia and Indonesia
Authors: Goh Chun Sheng , Potter Lesley 
Published: May 2022

AbstractMalaysia and Indonesia are two vivid examples of economic development built upon land exploitation. The concept of ‘bio‐economy’ illustrates a pathway for countries to move on to a more sustainable course of development by creating added value downstream and diversifying away from primary production. Growing a local oleochemical industry was naturally the first step for Malaysia and Indonesia as the world's largest palm‐oil producers. This was extended to biofuel production, which first aimed for export revenues. The biofuel sector later became an important buffer for the palm‐oil industry to absorb excessive stock with domestic blending targets during low price periods. Meanwhile, the utilization of biomass for power generation has grown significantly for both exports and local use. Converting biomass into second‐generation biofuels and other advanced bio‐based materials has also attracted great interest from foreign investors. However, the high cost of biomass mobilization has limited the deployment of advanced biorefineries. One interesting option is to integrate waste management with the production of high‐value bioenergy and biomaterials, adopting the model of a multi‐feedstock biorefinery. While several bio‐based industrial clusters were set up to attract investment with the consolidation of infrastructure surrounding major ports, more effort is still needed to explore and identify feasible business models with optimized supply chains. Cross‐border cooperation may open new doors for building regional bio‐based value chains. The ongoing digital revolution may provide breakthroughs in chain integration and technology deployment. © 2022 Society of Chemical Industry and John Wiley & Sons, Ltd.

AbstractBackgroundTo minimize drug‐related toxicity and monitor dosing regimens, an ultra‐sensitive, simple and high‐throughput analytical method for therapeutic drug monitoring is required. A novel LC–MS/MS bioassay of levetiracetam, lamotrigine and 10‐hydroxycarbazepine in human plasma was established. The analytes were separated on a Hypersil GOLD™ C18 column under a 2.5 min isocratic elution after one‐step protein precipitation. MS detection was performed under electrospray ionization positive‐mode fitted with selected reaction monitoring. The validated ranges were 0.1–20 μg/ml for LTG, 0.3–60 μg/ml for 10‐hydroxycarbazepine and levetiracetam. The intra‐ and inter‐batches of precision and accuracy was within ±15%. The novel method met all other criteria. Conclusion: This method can be used to monitor drug concentrations and decision‐making in epileptic patients.

AbstractIntroductionBipolar disorder (BD) and migraine headaches are frequently comorbid. The common etiological features are unknown, however cortical hyperexcitability (EEG) of migraines, and the report of hyperexcitability in pluripotent stem cell‐derived neurons from lithium responsive BD subjects offers a physiological hypothesis of excitable neurons linking these disorders. However, clinical studies suggest that a history of migraine is associated with higher rates of relapse in those with BD taking lithium. Lithium use and history of migraine in this prospective longitudinal study of BD find that lithium use is associated with a greater symptom severity in BD.MethodsData on longitudinal outcome from 538 patients with BD I were categorized according to treatment with lithium and comorbidity with migraine. Clinical outcome measures on depression, mania, and quality of life over the most recent 2‐year period compared the BD and BD/migraine cohort according to lithium treatment status.ResultsA history of migraines was associated with worse clinical outcomes of depression (p = .002), mania (p = .005), and mental and physical quality of life (p = .004 and p = .005, respectively), independent of lithium use. The BD/migraine cohort treated with lithium was associated with worse symptoms of mania, whereas those without migraine and lithium use were associated with milder manic symptoms (p = .026).ConclusionsHerein, we replicate the relatively worse outcome in BD with comorbid migraine. We find evidence to suggest that lithium use is associated with more severe symptoms of mania among those with BD and a history of migraine and conclude that lithium is contraindicated in BD comorbid with migraine.

AbstractIntroductionBidirectional effects between cognition and pain have been extensively reported. Although brain regions involved in cognitive and pain processing seem to partly overlap, it is unknown what specific brain regions are involved in the interaction between pain and cognition. Furthermore, the role of gonadal hormones on these interacting effects has not been examined. This study investigated brain activation patterns of the interaction between pain and cognition over different phases of the naturally occurring menstrual cycle.MethodsFifteen healthy normally cycling females were examined over the course of 4 different cycle phases. Sensory stimulation was applied using electrical pulses and cognitive performance was assessed using the Multi‐Source Interference Task. Brain imaging consisted of functional magnetic resonance imaging using a repeated measures ANOVA group analysis approach.ResultsSensory stimulation was found to interact with task performance in the left precuneus, left posterior cingulate cortex and right inferior parietal lobule. No effects of cycle phase were observed to interact with main effects of stimulation, task or interaction effects between task performance and sensory stimulation.ConclusionPotential neural correlates of shared resources between pain and cognition were demonstrated providing further insights into the potential mechanisms behind cognitive performance difficulties in pain patients and opening avenues for new treatment options including targeting specific cognitive factors in pain treatment such as cognitive interference.
