Revisiting the Definition of Solar Cell Generations
Authors: Schmid Martina 
Published: August 2023

AbstractThe classification of photovoltaic technologies into generations aims at facilitating the overview and equally can support the identification of future trends. The initial definition by Martin Green follows the historical development, which however does not necessarily need to imply that a certain technology is old or outdated. To find an update of that early graph without immediately refusing the initial classification, first, the representation is filled with up‐to‐date numbers. Despite several new definitions of generations being introduced, these merely stay on a general level without quantitative justification. Here, in contrast, classification is further strengthened by numbers of the latest efficiency records and module prices. By becoming specific, it is possible to draw the current picture, compare it to the initial idea and reveal novel trends and potential. Showing different representations of the quantitative values further allows setting a focus of investigation and looking at the situation from various perspectives. In this way, it is expected to support the discussion not just of classification but rather of future technology potential, which becomes apparent from parallel trends. In addition, the importance of advanced optical designs for future competitive efficiency enhancement will be presented.

Published: August 2023

AbstractOrganic luminophores with high emission efficiency in solution as well as solid‐state have received increasing attention due to their promising applications in biosensors, biological imaging, and optoelectronic devices. Herein, four triphenylamine (TPA)‐substituted boron ketoimine molecules (TPA‐BKI a‐d) are designed and synthesized by combining a donor‐acceptor (D‐A) electronic system and highly twisted block. The asymmetry of molecular and the planarity of the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO) sides in the excited state endow TPA‐BKI a‐d with rigidified conformations, allowing bright emission in dilute solution. Additionally, their highly twisted structures avoid close contact between molecules and detrimental exciton interactions, leading to efficient emission in the solid state. Meanwhile, the emission colors are modulated by the incorporation of different substituents through the amino‐yne click reaction. Furthermore, because of the protonation and deprotonation of the amino substituents, TPA‐BKI‐d exhibits reversible alterations of optical properties in both solution and solid states.

AbstractIt is significantly important to design fluorescent probes with excellent stimulated emission (SE) efficiency for low‐power stimulated emission depletion (STED) imaging. Herein, 4,6‐bis((E)‐4‐(dibenzothiophene)styryl)‐5(ethoxycarbonyl)‐2,2‐difluoro‐2H‐1,3,2‐ dioxaborinin‐1‐ium‐2‐uide (BBSF) is chosen as guest fluorescence molecule and 4,4′‐bis9H‐carbazol‐9‐ylbiphenyl (CBP) selected as host matrix. It is demonstrated that BBSF@CBP microcrystals possess outstanding amplified stimulated emission (ASE) behavior and thermally activated delayed fluorescent (TADF) characteristics, which are beneficial for achieving low‐power STED imaging through decreasing the saturation intensity. Moreover, BBSF and CBP molecules are encapsulated into polyethylene‐polypropylene glycol (Pluronic F127) to form amphipathic BBSF@CBP nanoparticles (NPs), which show bright red emission with extraordinary fluorescence quantum yield (Φ) of 0.375, large Stokes’ shift of 190 nm, appropriate long‐lived lifetime of 16.17 ns, and high photostability. The measured saturation intensity and lateral resolution of BBSF@CBP NPs are 0.28 MW cm−2 and 73.77 nm, respectively. Moreover, STED imaging in living HeLa cells with enhanced resolution of 72.20 nm is also achieved by utilizing the prepared BBSF@CBP NPs. This study demonstrates the high performance of TADF NPs, making them promising as fluorescent probes for low‐power STED imaging in living cells.

Published: August 2023

AbstractConstructing nanostructures with high structural stability and ultrafast electrochemical reaction kinetics as anodes for sodium‐ion batteries (SIBs) is a big challenge. Herein, the robust 2D VS2/ Ti3C2Tx MXene nanostructures with the strong Ti─S covalent bond synthesized by a one‐pot self‐assembly approach are developed. The strong interfacial interaction renders the material of good structural durability and enhanced reaction kinetics. Meanwhile, the enlarged and few‐layered MXene nanosheets can be easily obtained according to this interaction, providing a conductive network for sufficient electrolyte penetration and rapid charge transfer. As predicted, the VS2/MXene nanostructures exhibit an extremely low sodium diffusion barrier confirmed by DFT calculations and small charge transfer impedance evidenced by electrochemical impedance spectroscopy (EIS) analysis. Therefore, the SIBs based on the VS2/MXene electrode present first‐class electrochemical performance with the ultrahigh average initial columbic efficiency of 95.08% and excellent sodium‐ion storage capacity of 424.6 mAh g−1 even at 10 A g−1. It also shows an outstanding sodium‐ion storage capacity of 514.2 mAh g−1 at 1 A g−1 with a capacity retention of nearly 100% within 500 times high‐rate cycling. Such impressive performance demonstrates the successful synthesis strategy and the great potential of interfacial interactions for high‐performance energy storage devices.

AbstractAlthough the advances in organic solar cells (OSCs) have been considerable, their efficiency is still limited by recombination losses. Photogenerated electrons and holes are generally bound as localized excitons in organic semiconductors. The transition from excitons into free charges requires diffusion and dissociation processes, in which parasitic recombination losses exist. Reducing these losses is necessary for highly efficient OSCs. The crystallization behavior of the active layers can influence the efficiency of exciton diffusion and dissociation. In this work, different additives are delicately designed to control the crystallization behavior. It is found that the crystallization quality of active layers can be improved by controlling the aggregation of nonfullerene acceptors. The π–π stacking of blend films becomes compact, meanwhile, the crystallization in the vertical direction is more uniform. These are beneficial to the diffusion and dissociation of excitons. As a consequence, recombination losses are reduced and power convention efficiencies (PCEs) are improved significantly. Meanwhile, the general applicability of the additive is demonstrated in various organic photovoltaic systems, in which a PCE of 19.3% is achieved in D18:BTP‐eC9‐4F OSCs. This work provides a facile strategy to reduce the recombination losses of excitons for efficient devices.

AbstractThe United States (US) is the world's largest beef producer and the third‐largest exporter. Beef production is also an important component of Texas history and economy. However, the US beef industry faces several challenges, including declining domestic consumption and competition for export markets. A potential strategy to overcome these challenges is promoting US beef products in international markets. Mexico is one of the markets of importance as it is the third‐largest export destination for US beef. In this study, we explored the use of “US” country of origin and “Texas” geographic indication information for consumer advertising of beef in Mexico. It was posited that Texas's international reputation as a cattle‐producing region could be used to promote Texas beef products. Data for this study were collected in 2019 and 2020 using an online survey of 1021 Mexican food shoppers. The survey included a choice experiment with 12 hypothetical choice scenarios of beef steak with different product attributes and prices. The product attributes considered were place of origin, food safety level, and production practices. Mexican consumers were found to have a strong preference for domestic beef products. Moreover, Mexican consumers are willing to pay $1.16 and $1.18/lb for enhanced food safety and natural production practices. Consumers are also willing to pay $0.19/lb more for US–Texas beef than that of US beef. The results of this project provide valuable information for developing marketing strategies and promotion campaigns aiming to improve the competitiveness of US and Texas beef products in foreign markets [EconLit Citations: D12, Q17, Q18].

AbstractWork is an important social determinant of health; unfortunately, work‐related injuries remain prevalent, can have devastating impact on worker health, and can impose heavy economic burdens on workers and society. Occupational health services research (OHSR) underpins occupational health services policy and practice, focusing on health determinants, health services, healthcare delivery, and health systems affecting workers. The field of OHSR has undergone tremendous expansion in both definition and scope over the past 25 years. In this commentary, focusing on the US, we document the historical development and evolution of OHSR as a research field, describe current doctoral‐level OHSR training, and discuss challenges and opportunities for the OHSR field. We also propose an updated definition for the OHSR field:Research and evaluation related to the determinants of worker health and well‐being; to occupational injury and illness prevention and surveillance; to healthcare, health programs, and health policy affecting workers; and to the organization, access, quality, outcomes, and costs of occupational health services and related health systems. Researchers trained in OHSR are essential contributors to improvements in healthcare, health systems, and policy and programs to improve worker health and productivity, as well as equity and justice in job and employment conditions. We look forward to the continued growth of OHSR as a field and to the expansion of OHSR academic training opportunities.

AbstractMLN4924 is known for its potential in cancer treatment and antiviral activity as a NEDD8‐activating enzyme (NAE) inhibitor. We designed and synthesized fluorinated MLN4924 derivatives by electrophilic fluorination at the 6′‐position and nucleophilic fluorination at the 2′‐position of the sugar moiety, respectively. The compounds were then evaluated for their anti‐HCMV activity, and compound 2 a exhibited the most potent HCMV inhibitory activity, showing similar results to MLN4924 but with no toxicity at a high concentration. Docking studies highlighted the importance of the sugar conformation in the binding interaction with the target protein. This research offers critical insights into the optimization of MLN4924 derivatives and provides a promising pathway towards the development of effective antiviral agents.

ObjectiveSmall‐cell lung cancer (SCLC) is the malignancy most frequently associated with paraneoplastic neurological syndromes (PNS) and can trigger different antibody responses against intracellular (Hu) or neuronal surface (GABABR) antigens. Our aim was to clarify whether the genomic and transcriptomic features of SCLC are different in patients with anti‐GABABR or anti‐Hu PNS compared with SCLC without PNS.MethodsA total of 76 SCLC tumor samples were collected: 34 anti‐Hu, 14 anti‐GABABR, and 28 SCLC without PNS. The study consisted of 4 steps: (1) pathological confirmation; (2) next generation sequencing using a panel of 98 genes, including those encoding the autoantibodies targets ELAVL1‐4, GABBR1‐2, and KCTD16; (3) genome‐wide copy number variation (CNV); and (4) whole‐transcriptome RNA sequencing.ResultsCNV analysis revealed that patients with anti‐GABABR PNS commonly have a gain in chromosome 5q, which contains KCTD16, whereas anti‐Hu and control patients often harbor a loss. No significantly different number of mutations regarding any onconeural genes was observed. Conversely, the transcriptomic profile of SCLC was different, and the differentially expressed genes allowed effective clustering of the samples into 3 groups, reflecting the antibody‐based classification, with an overexpression of KCTD16 specific to anti‐GABABR PNS. Pathway analysis revealed that tumors of patients with anti‐GABABR encephalitis were enriched in B‐cell signatures, as opposed to those of patients with anti‐Hu, in which T‐cell‐ and interferon‐γ‐related signatures were overexpressed.InterpretationSCLC genetic and transcriptomic features differentiate anti‐GABABR, anti‐Hu, and non‐PNS tumors. The role of KCTD16 appears to be pivotal in the tumor immune tolerance breakdown of anti‐GABABR PNS. ANN NEUROL 2023;94:1102–1115
Photochemical Desaturation and Epoxidation with Oxygen by Sequential Flavin Catalysis
Authors: Walter Alexandra , Eisenreich Wolfgang , Storch Golo 
Published: August 2023

AbstractCatalytic desaturations are important strategies for the functionalization of organic molecules. In nature, flavoenzymes mediate the formation of α,β‐unsaturated carbonyl compounds by concomitant cofactor reduction. Contrary to many laboratory methods for these reactions, such as the Saegusa‐Ito oxidation, no transition metal reagents or catalysts are required. However, a molecular flavin‐mediated variant has not been reported so far. We disclose a photochemical approach for silyl enol ether oxidation, which leads to α,β‐unsaturated ketones (13 examples) in very good yields. The flavin catalysts are stable throughout the desaturation reaction, and we successfully applied them in a subsequent aerobic epoxidation by simply changing the reaction conditions. This protocol allowed us to directly convert silyl enol ethers into α,β‐epoxyketones in a one‐pot fashion (12 examples). Sequential flavin catalysis is not limited to one specific reactivity combination and can, inter alia, couple the photochemical oxidation with radical additions. We anticipate that flavin‐catalyzed desaturation will be applicable to other substrate classes and that its sequential catalytic activity will enable rapid substrate diversification.

AbstractNovel photochromic and long‐persistent photoluminescent electrospun nanofibrous films were developed for anticounterfeiting applications. The inclusion of rare‐earth activated strontium aluminum oxide (RSAO) nano‐scaled particles into nanofibers of cellulose acetate‐polycaprolactone (CA‐PCL) composite facilitated the development of a simple method for creating an organic–inorganic photoluminescent nanocomposite. Upon excitation at 365 nm, the luminescent nanofibrous films showed an emission band of 516 nm. The current from photochromic films change color to green when illuminated with ultraviolet light as proved by absorption and fluorescence analyses, and CIE Lab parameters. Both mechanical and hydrophobic properties of the electrospun films were found to improve with raising RSAO content in CA‐PCL. Improved hydrophobic performance was monitored without any compromise to their other desirable properties. The morphology of the synthesized phosphor nanoparticles was investigated to indicate particle diameter of 2–12 nm, whereas the morphology of the electrospun nanofibers displayed diameters of 200–300 nm. The cytotoxicity of RSAO was also explored using the MTT proliferation assay. When exposed to UV, the nanofibrous films showed reversible photochromism without fatigue

Published: August 2023

AbstractMagnetic composite hydrogels exhibit promising prospects for diverse applications, but their mechanical properties impose limitations on their further advancement. In this study, a novel approach is proposed to directly prepare magnetic composite hydrogels utilizing nanoferroferric oxide, aiming to replace the existing preparation method. Meanwhile, graphene oxide (GO) is introduced into magnetic composite hydrogels to enhance their mechanical characteristics. By employing ammonium citrate (AC) as a dispersant, the dispersion of ferroferric oxide magnetic nanoparticles at a concentration of 40 mg/mL is achieved, enabling their coexistence with GO for the preparation of magnetic composite hydrogels. Notably, the incorporation of 3 mg/mL GO and 40 mg/mL magnetic nanoparticles in polyacrylamide (PAM) hydrogel yields remarkable improvements in maximum stress and strain, reaching 148 kPa and 496%, respectively. In contrast, magnetic composite hydrogels without GO exhibit lower values of 46.5 kPa and 351%. The presence of magnetic nanoparticles imparts magnetism to the hydrogel, with higher concentrations of magnetic nanoparticles leading to increased magnetism. Moreover, the presence of AC and GO renders the hydrogels electronegative, thereby endowing them with selective adsorption capabilities. In summary, the magnetic composite hydrogels prepared by one‐pot method have good mechanical properties and selective adsorption capacity, and have good application potential.
Pain after cancer: Time to move towards a mechanism‐based approach!
Authors: Meeus Mira 
Published: August 2023

AbstractThe high prevalence and the debilitating nature of pain following cancer urge the need for appropriate pain assessment and management in this population. Yet cancer pain remains under‐recognized and under‐treated. For effective pain management, correct identification of the presence of different underlying pain mechanisms is warranted, since pain management strategies differ considerably according to the predominant mechanisms. To raise awareness around possible underlying pain mechanisms in pain after cancer, the three major pain mechanisms are shortly explained and translated to this specific population. Next, in this Special Issue, we delve further into the existing evidence on the presence of these pain mechanisms in patients with pain after cancer, and on how they can be assessed or approached in patients with pain after cancer.

AbstractBrain dissection is typically an important part of teaching neuroscience in health professional programs. This results in the need to effectively remove brains, which is often performed in a gross anatomy laboratory in the same curriculum. The aim of this study was to determine the most effective method of brain removal based on the time required for removal, difficulty of removal, and preservation of key brain structures for educational purposes. Six different dissectors performed each of the three calvaria removal approaches and three different spinal cord transection methods rating them for difficulty and tracking the time required. The combination of calvaria and brainstem approaches and the order of completion was randomized to control for fatigue and previous individual experience. After all brains were removed, each was evaluated by neuroscience faculty for utility in education contexts. The study found little difference between the individual approaches for both calvaria removal and spinal cord transection in regards to quality of outcome. The use of a circumferential cut only proved to be the most time‐effective method for calvaria removal while a posterior cut between C1 and C2 was the most time‐effective and least difficult method for brainstem release. There was no one technique that proved to be most beneficial across all three measures. However, different approaches resulted in a different combination of benefits across the time, difficulty, and outcome ratings that should be considered in light of the individual needs of any program or researcher.

Published: August 2023

AbstractTargeted treatment of cancer is one of the most paramount approaches in cancer treatment. Despite significant advances in cancer diagnosis and treatment methods, there are still significant limitations and disadvantages in the field, including high costs, toxicity, and unwanted damage to healthy cells. The phage display technique is an innovative method for designing carriers containing exogenic peptides with cancer diagnostic and therapeutic properties. Bacteriophages possess unique properties making them effective in cancer treatment. These characteristics include the small size enabling them to penetrate vessels; having no pathogenicity to mammals; easy manipulation of their genetic information and surface proteins to introduce vaccines and drugs to cancer tissues; lower cost of large‐scale production; and greater stimulation of the immune system. Bacteriophages will certainly play a more effective role in the future of medical oncology; however, studies are in the early stages of conception and require more extensive research. We aimed in this review to provide some related examples and bring insights into the potential of phages as targeted vectors for use in cancer diagnosis and treatment, especially regarding their capability in gene and drug delivery to cancer target cells, determination of tumor markers, and vaccine design to stimulate anticancer immunity.
